Azure Application Gateway Logs capture essential information like access to your gateways (caller's IP, response latency, and more) or security events to detect or prevent threats.
Supported log categories:
Log Category | Description |
---|---|
This log can be used to view Application Gateway access patterns and analyze important information. This includes the caller's IP, requested URL, response latency, return code, and bytes in and out. An access log is collected every 60 seconds. This log contains one record per instance of Application Gateway. The Application Gateway instance is identified by the instanceId property. | |
This log can be used to view the requests that are logged through either detection or prevention mode of an application gateway that is configured with the web application firewall. Firewall logs are collected every 60 seconds. |
Requirements and setup
Refer to the Azure Logs page for more information about setting up and using this integration.
Settings
eventhub
:
string
An Event Hub is a fully managed, real-time data ingestion service. Elastic recommends using only letters, numbers, and the hyphen (-) character for Event Hub names to maximize compatibility. You can use existing Event Hubs having underscores (_) in the Event Hub name; in this case, the integration will replace underscores with hyphens (-) when it uses the Event Hub name to create dependent Azure resources behind the scenes (e.g., the storage account container to store Event Hub consumer offsets). Elastic also recommends using a separate event hub for each log type as the field mappings of each log type differ.
Default value insights-operational-logs
.
consumer_group
:
string
The publish/subscribe mechanism of Event Hubs is enabled through consumer groups. A consumer group is a view (state, position, or offset) of an entire event hub. Consumer groups enable multiple consuming applications to each have a separate view of the event stream, and to read the stream independently at their own pace and with their own offsets.
Default value: $Default
connection_string
:
string
The connection string is required to communicate with Event Hubs, see steps here.
A Blob Storage account is required in order to store/retrieve/update the offset or state of the eventhub messages. This means that after stopping the Azure logs package it can start back up at the spot that it stopped processing messages.
storage_account
:
string
The name of the storage account where the state/offsets will be stored and updated.
storage_account_key
:
string
The storage account key, this key will be used to authorize access to data in your storage account.
storage_account_container
:
string
The storage account container where the integration stores the checkpoint data for the consumer group. It is an advanced option to use with extreme care. You MUST use a dedicated storage account container for each Azure log type (activity, sign-in, audit logs, and others). DO NOT REUSE the same container name for more than one Azure log type. See Container Names for details on naming rules from Microsoft. The integration generates a default container name if not specified.
resource_manager_endpoint
:
string
Optional, by default we are using the azure public environment, to override, users can provide a specific resource manager endpoint in order to use a different azure environment.
Resource manager endpoints:
# Azure ChinaCloud
https://management.chinacloudapi.cn/
# Azure GermanCloud
https://management.microsoftazure.de/
# Azure PublicCloud
https://management.azure.com/
# Azure USGovernmentCloud

Logs
application_gateway
The application_gateway
data stream of the Azure Logs package will collect any Application Gateway log events that have been streamed through an Azure event hub.
An example event for application_gateway
looks as following:

Exported fields
Field | Description | Type |
---|---|---|
@timestamp | Event timestamp. | date |
azure.application_gateway.action | Action taken on the request. Available values are: Blocked and Allowed (for custom rules) Matched (when a rule matches a part of the request) Detected and Blocked (these are both for mandatory rules, depending on if the WAF is in detection or prevention mode). | keyword |
azure.application_gateway.hostname | Hostname or IP address of the Application Gateway. | keyword |
azure.application_gateway.instance_id | Application Gateway instance for which firewall data is being generated. For a multiple-instance application gateway, there is one row per instance. | keyword |
azure.application_gateway.operation_name | Operation name | keyword |
azure.application_gateway.policy.id | Unique ID of the Firewall Policy associated with the Application Gateway, Listener, or Path. | keyword |
azure.application_gateway.policy.scope | The location of the policy - values can be "Global", "Listener", or "Location". | keyword |
azure.application_gateway.policy.scope_name | The name of the object where the policy is applied. | keyword |
azure.application_gateway.transaction_id | Unique ID for a given transaction which helps group multiple rule violations that occurred within the same request. | keyword |
azure.correlation_id | Correlation ID | keyword |
azure.resource.authorization_rule | Authorization rule | keyword |
azure.resource.group | Resource group | keyword |
azure.resource.id | Resource ID | keyword |
azure.resource.name | Name | keyword |
azure.resource.namespace | Resource type/namespace | keyword |
azure.resource.provider | Resource type/namespace | keyword |
azure.subscription_id | Azure subscription ID | keyword |
azure.tenant_id | tenant ID | keyword |
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.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
data_stream.dataset | Data stream dataset. | constant_keyword |
data_stream.namespace | Data stream namespace. | constant_keyword |
data_stream.type | Data stream type. | 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 |
destination.bytes | Bytes sent from the destination to the source. | long |
destination.domain | The domain name of the destination system. This value may be a host name, a fully qualified domain name, or another host naming format. The value may derive from the original event or be added from enrichment. | 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.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.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.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 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.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 |
http.request.method | HTTP request method. The value should retain its casing from the original event. For example, GET , get , and GeT are all considered valid values for this field. | keyword |
http.response.status_code | HTTP response status code. | long |
http.version | HTTP version. | keyword |
message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message. | match_only_text |
network.bytes | Total bytes transferred in both directions. If source.bytes and destination.bytes are known, network.bytes is their sum. | long |
network.protocol | In the OSI Model this would be the Application Layer protocol. For example, http , dns , or ssh . The field value must be normalized to lowercase for querying. | keyword |
observer.name | Custom name of the observer. This is a name that can be given to an observer. This can be helpful for example if multiple firewalls of the same model are used in an organization. If no custom name is needed, the field can be left empty. | keyword |
observer.product | The product name of the observer. | keyword |
observer.type | The type of the observer the data is coming from. There is no predefined list of observer types. Some examples are forwarder , firewall , ids , ips , proxy , poller , sensor , APM server . | keyword |
observer.vendor | Vendor name of the observer. | keyword |
related.hosts | All hostnames or other host identifiers seen on your event. Example identifiers include FQDNs, domain names, workstation names, or aliases. | keyword |
related.ip | All of the IPs seen on your event. | ip |
rule.category | A categorization value keyword used by the entity using the rule for detection of this event. | keyword |
rule.description | The description of the rule generating the event. | keyword |
rule.id | A rule ID that is unique within the scope of an agent, observer, or other entity using the rule for detection of this event. | keyword |
rule.ruleset | Name of the ruleset, policy, group, or parent category in which the rule used to generate this event is a member. | keyword |
rule.version | The version / revision of the rule being used for analysis. | keyword |
source.address | Some event source 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 |
source.as.number | Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet. | long |
source.as.organization.name | Organization name. | keyword |
source.as.organization.name.text | Multi-field of source.as.organization.name . | match_only_text |
source.bytes | Bytes sent from the source to the destination. | long |
source.geo.city_name | City name. | keyword |
source.geo.continent_name | Name of the continent. | keyword |
source.geo.country_iso_code | Country ISO code. | keyword |
source.geo.country_name | Country name. | keyword |
source.geo.location | Longitude and latitude. | geo_point |
source.geo.name | User-defined description of a location, at the level of granularity they care about. Could be the name of their data centers, the floor number, if this describes a local physical entity, city names. Not typically used in automated geolocation. | keyword |
source.geo.region_iso_code | Region ISO code. | keyword |
source.geo.region_name | Region name. | keyword |
source.ip | IP address of the source (IPv4 or IPv6). | ip |
source.port | Port of the source. | long |
tags | List of keywords used to tag each event. | keyword |
url.domain | Domain of the url, such as "www.elastic.co". In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the domain field. If the URL contains a literal IPv6 address enclosed by [ and ] (IETF RFC 2732), the [ and ] characters should also be captured in the domain field. | keyword |
url.original | Unmodified original url as seen in the event source. Note that in network monitoring, the observed URL may be a full URL, whereas in access logs, the URL is often just represented as a path. This field is meant to represent the URL as it was observed, complete or not. | wildcard |
url.original.text | Multi-field of url.original . | match_only_text |
url.path | Path of the request, such as "/search". | wildcard |
url.query | The query field describes the query string of the request, such as "q=elasticsearch". The ? is excluded from the query string. If a URL contains no ? , there is no query field. If there is a ? but no query, the query field exists with an empty string. The exists query can be used to differentiate between the two cases. | keyword |
