This is an integration for Zeek, which was formerly named Bro. Zeek is a passive, open-source network traffic analyzer. This integrations ingests the logs Zeek produces about the network traffic that it analyzes.
Zeek logs must be output in JSON format. This is normally done by appending the
json-logs policy
to your local.zeek
file. Add this line to your local.zeek
.
@load policy/tuning/json-logs.zeek
Compatibility
This module has been developed against Zeek 2.6.1, but is expected to work with other versions of Zeek.
Zeek requires a Unix-like platform, and it currently supports Linux, FreeBSD, and Mac OS X.
Logs
capture_loss
The capture_loss
dataset collects the Zeek capture_loss.log file,
which contains packet loss rate data.
Exported fields
Field | Description | Type |
---|---|---|
@timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
cloud.account.id | The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier. | keyword |
cloud.availability_zone | Availability zone in which this host, resource, or service is located. | keyword |
cloud.image.id | Image ID for the cloud instance. | keyword |
cloud.instance.id | Instance ID of the host machine. | keyword |
cloud.instance.name | Instance name of the host machine. | keyword |
cloud.machine.type | Machine type of the host machine. | keyword |
cloud.project.id | The cloud project identifier. Examples: Google Cloud Project id, Azure Project id. | keyword |
cloud.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
cloud.region | Region in which this host, resource, or service is located. | keyword |
container.id | Unique container id. | keyword |
container.image.name | Name of the image the container was built on. | keyword |
container.labels | Image labels. | object |
container.name | Container name. | keyword |
data_stream.dataset | The field can contain anything that makes sense to signify the source of the data. Examples include nginx.access , prometheus , endpoint etc. For data streams that otherwise fit, but that do not have dataset set we use the value "generic" for the dataset value. event.dataset should have the same value as data_stream.dataset . Beyond the Elasticsearch data stream naming criteria noted above, the dataset value has additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.namespace | A user defined namespace. Namespaces are useful to allow grouping of data. Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with default . If no value is used, it falls back to default . Beyond the Elasticsearch index naming criteria noted above, namespace value has the additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.type | An overarching type for the data stream. Currently allowed values are "logs" and "metrics". We expect to also add "traces" and "synthetics" in the near future. | constant_keyword |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |

event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset | constant_keyword |
event.ingested | Timestamp when an event arrived in the central data store. This is different from @timestamp , which is when the event originally occurred. It's also different from event.created , which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested . | date |

They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization.

container.labels | Image labels. | object |
container.name | Container name. | keyword |
data_stream.dataset | The field can contain anything that makes sense to signify the source of the data. Examples include nginx.access , prometheus , endpoint etc. For data streams that otherwise fit, but that do not have dataset set we use the value "generic" for the dataset value. event.dataset should have the same value as data_stream.dataset . Beyond the Elasticsearch data stream naming criteria noted above, the dataset value has additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.namespace | A user defined namespace. Namespaces are useful to allow grouping of data. Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with default . If no value is used, it falls back to default . Beyond the Elasticsearch index naming criteria noted above, namespace value has the additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.type | An overarching type for the data stream. Currently allowed values are "logs" and "metrics". We expect to also add "traces" and "synthetics" in the near future. | constant_keyword |

This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |

event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization.

dns.answers.data | The data describing the resource. The meaning of this data depends on the type and class of the resource record. | keyword |
dns.answers.name | The domain name to which this resource record pertains. If a chain of CNAME is being resolved, each answer's name should be the one that corresponds with the answer's data . It should not simply be the original question.name repeated. | keyword |
dns.answers.ttl | The time interval in seconds that this resource record may be cached before it should be discarded. Zero values mean that the data should not be cached. | long |
dns.answers.type | The type of data contained in this resource record. | keyword |
dns.header_flags | Array of 2 letter DNS header flags. | keyword |
dns.id | The DNS packet identifier assigned by the program that generated the query. The identifier is copied to the response. | keyword |
dns.question.class | The class of records being queried. | keyword |
dns.question.name | The name being queried. If the name field contains non-printable characters (below 32 or above 126), those characters should be represented as escaped base 10 integers (\DDD). Back slashes and quotes should be escaped. Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively. | keyword |
dns.question.registered_domain | The highest registered domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". | keyword |
dns.question.subdomain | The subdomain is all of the labels under the registered_domain. If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period. | keyword |
dns.question.top_level_domain | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". | keyword |
dns.question.type | The type of record being queried. | keyword |
dns.resolved_ip | Array containing all IPs seen in answers.data . The answers array can be difficult to use, because of the variety of data formats it can contain. Extracting all IP addresses seen in there to dns.resolved_ip makes it possible to index them as IP addresses, and makes them easier to visualize and query for. | ip |
dns.response_code | The DNS response code. | keyword |
dns.type | The type of DNS event captured, query or answer. If your source of DNS events only gives you DNS queries, you should only create dns events of type dns.type:query . If your source of DNS events gives you answers as well, you should create one event per query (optionally as soon as the query is seen). And a second event containing all query details as well as an array of answers. | keyword |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
error.message | Error message. | match_only_text |
event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type , which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset | constant_keyword |
event.duration | Duration of the event in nanoseconds. If event.start and event.end are known this value should be the difference between the end and start time. | long |
event.id | Unique ID to describe the event. | keyword |
event.ingested | Timestamp when an event arrived in the central data store. This is different from @timestamp , which is when the event originally occurred. It's also different from event.created , which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested . | date |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.original | Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source . If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference . | keyword |
event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome , according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info , or any events for which an outcome does not make logical sense. | keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |

Beyond the Elasticsearch data stream naming criteria noted above, the dataset value has additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.namespace | A user defined namespace. Namespaces are useful to allow grouping of data. Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with default . If no value is used, it falls back to default . Beyond the Elasticsearch index naming criteria noted above, namespace value has the additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.type | An overarching type for the data stream. Currently allowed values are "logs" and "metrics". We expect to also add "traces" and "synthetics" in the near future. | constant_keyword |

event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |

container.name | Container name. | keyword |
data_stream.dataset | The field can contain anything that makes sense to signify the source of the data. Examples include nginx.access , prometheus , endpoint etc. For data streams that otherwise fit, but that do not have dataset set we use the value "generic" for the dataset value. event.dataset should have the same value as data_stream.dataset . Beyond the Elasticsearch data stream naming criteria noted above, the dataset value has additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.namespace | A user defined namespace. Namespaces are useful to allow grouping of data. Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with default . If no value is used, it falls back to default . Beyond the Elasticsearch index naming criteria noted above, namespace value has the additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.type | An overarching type for the data stream. Currently allowed values are "logs" and "metrics". We expect to also add "traces" and "synthetics" in the near future. | constant_keyword |
destination.address | Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain , depending on which one it is. | keyword |

event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset | constant_keyword |
event.ingested | Timestamp when an event arrived in the central data store. This is different from @timestamp , which is when the event originally occurred. It's also different from event.created , which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested . | date |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.original | Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex.

Exported fields
Field | Description | Type |
---|---|---|
@timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
client.address | Some event client addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain , depending on which one it is. | keyword |

container.name | Container name. | keyword |
data_stream.dataset | The field can contain anything that makes sense to signify the source of the data. Examples include nginx.access , prometheus , endpoint etc. For data streams that otherwise fit, but that do not have dataset set we use the value "generic" for the dataset value. event.dataset should have the same value as data_stream.dataset . Beyond the Elasticsearch data stream naming criteria noted above, the dataset value has additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.namespace | A user defined namespace. Namespaces are useful to allow grouping of data. Many users already organize their indices this way, and the data stream naming scheme now provides this best practice as a default. Many users will populate this field with default . If no value is used, it falls back to default . Beyond the Elasticsearch index naming criteria noted above, namespace value has the additional restrictions: * Must not contain - * No longer than 100 characters | constant_keyword |
data_stream.type | An overarching type for the data stream. Currently allowed values are "logs" and "metrics". We expect to also add "traces" and "synthetics" in the near future. | constant_keyword |
destination.address | Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain , depending on which one it is. | keyword |

error.message | Error message. | match_only_text |
event.action | The action captured by the event. This describes the information in the event. It is more specific than event.category . Examples are group-add , process-started , file-created . The value is normally defined by the implementer. | keyword |
event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type , which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset | constant_keyword |
event.id | Unique ID to describe the event. | keyword |
event.ingested | Timestamp when an event arrived in the central data store. This is different from @timestamp , which is when the event originally occurred. It's also different from event.created , which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested . | date |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome , according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info , or any events for which an outcome does not make logical sense. | keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
host.architecture | Operating system architecture. | keyword |
host.containerized | If the host is a container. | boolean |
host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |
host.hostname | Hostname of the host. It normally contains what the hostname command returns on the host machine. | keyword |
host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name . | keyword |
host.ip | Host ip addresses. | ip |
host.mac | Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen. | keyword |
host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. | keyword |
