Overview

Apache Tomcat is a free and open-source implementation of the jakarta servlet, jakarta expression language, and websocket technologies. It provides a pure java http web server environment in which java code can also run. Thus, it is a java web application server, although not a full JEE application server.

Use the Apache Tomcat integration to:

  • Collect metrics related to the cache, connection pool, memory, request, session and thread pool and collect logs related to access, catalina, and localhost.
  • Create visualizations to monitor, measure and analyze the usage trend and key data, and derive business insights.
  • Create alerts to reduce the MTTD and also the MTTR by referencing relevant logs when troubleshooting an issue.

Data streams

The Apache Tomcat integration collects logs and metrics data.

Logs help you keep a record of events that happen on your machine. The Log data streams collected by Apache Tomcat integration are access, catalina, and localhost, so that users can keep track of the IP addresses of the clients, bytes returned to the client or sent by clients, etc., so that users could monitor and troubleshoot the performance of Java applications.

Metrics give you insight into the statistics of the Apache Tomcat. The Metric data streams collected by the Apache Tomcat integration are cache, connection pool, memory, request, session and thread pool, so that the user can monitor and troubleshoot the performance of the Apache Tomcat instance.

Data streams:

  • access: Collects information related to the HTTP transactions, client IP, response code and request processing time.
  • cache: Collects information related to the overall cache of the Apache Tomcat instance.
  • catalina: Collects information related to the startup and shutdown of the Apache Tomcat application server, the deployment of new applications, or the failure of one or more subsystems.
  • connection pool: Collects information related to connection pool such as number of active and idle connections.
  • localhost: Collects information related to Web application activity which is related to HTTP transactions between the application server and the client.
  • memory: Collects information related to heap memory, non-heap memory and garbage collection of the Tomcat instance.
  • request: Collects information related to requests of the Apache Tomcat instance.
  • thread pool: Collects information related to the overall states of the threads, CPU time and processing termination time of the threads in the Tomcat instance.
  • session: Collects information related to overall created, active and expired sessions of the Tomcat instance.

Note:

  • Users can monitor and see the log inside the ingested documents for Apache Tomcat in the logs-* index pattern from Discover, and for metrics, the index pattern is metrics-*.

Compatibility

This integration has been tested against Apache Tomcat versions 10.1.5, 9.0.71 and 8.5.85, and Prometheus version 0.20.0.

Prerequisites

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended or self-manage the Elastic Stack on your own hardware.

In order to ingest data from the Apache Tomcat, user must have

  • Configured Prometheus in Apache Tomcat instance

Setup

For step-by-step instructions on how to set up an integration, see the Getting started guide.

Steps to setup Prometheus

Here are the steps to configure Prometheus in Apache Tomcat instance:

  1. Go to <TOMCAT_HOME>/webapps from Apache Tomcat instance.

  2. Please find latest Prometheus version, replace in below command and perform from Apache Tomcat instance: -

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/<prometheus_version>/jmx_prometheus_javaagent-<prometheus_version>.jar
  1. Create config.yml file in <TOMCAT_HOME>/webapps and paste the following content in config.yml file: -
rules:
- pattern: ".*"
  1. Go to /etc/systemd/system and add the following content within the [Service] section of the tomcat.service file: -
Environment='JAVA_OPTS=-javaagent:<TOMCAT_HOME>/webapps/jmx_prometheus_javaagent-<prometheus_version>.jar=<prometheus_port>:/opt/tomcat/webapps/config.yml'
  1. Run the following commands to reload the systemd manager configuration and restart the Apache Tomcat service to set the updated environment variable: -
systemctl daemon-reload
systemctl restart tomcat

Steps to configure Filestream input for Access logs

Here are the steps to configure Log format in Apache Tomcat instance:

  1. Go to <TOMCAT_HOME>/conf/server.xml from Apache Tomcat instance.

  2. The user can update the log format in the pattern field of the class org.apache.catalina.valves.AccessLogValve. Here is an example of the org.apache.catalina.valves.AccessLogValve class.

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
       prefix="localhost_access_log" suffix=".txt"
       pattern='%h %l %u %t "%r" %s %b %A %X %T "%{Referer}i" "%{User-Agent}i" X-Forwarded-For="%{X-Forwarded-For}i"' />
  1. The supported log formats are:
Common Log Format :- '%h %l %u %t "%r" %s %b'
Combined Log Format :- '%h %l %u %t "%r" %s %b "%{Referrer}i" "%{User-Agent}i"'
Combined Log Format + X-Forwarded-For header :- '%h %l %u %t "%r" %s %b %A %X %T "%{Referer}i" "%{User-Agent}i" X-Forwarded-For="%{X-Forwarded-For}i"'
  1. Run the following commands to restart Apache Tomcat instance: -
systemctl restart tomcat

Supported log formats for Catalina and Localhost logs:

  • With error stack trace:
dd-MMM-yyyy HH:mm:ss.SSS [Severity] [Subsystem] [Message Text] [Error Stack Trace]
  • Without error stack trace:
dd-MMM-yyyy HH:mm:ss.SSS [Severity] [Subsystem] [Message Text]

Note:

  • Restarting Apache Tomcat does not affect the virtual desktops that are currently running. It will only prevent new users from logging in for the duration of the restart process (typically several seconds).
  • A user can support a new format of log by writing their own custom ingest pipelines. To facilitate the multiline parsing of catalina and localhost logs, the multiline configuration can be used to match the multiline pattern of logs.

Configuration

You need the following information from your Apache Tomcat instance to configure this integration in Elastic:

Apache Tomcat Hostname

Host Configuration Format: http[s]://<hostname>:<port>/<metrics_path>

Example Host Configuration: http://localhost:9090/metrics

Validation

After the integration is successfully configured, clicking on the Assets tab of the Apache Tomcat Integration should display a list of available dashboards. Click on the dashboard available for your configured data stream. It should be populated with the required data.

Troubleshooting

  • apache_tomcat.access.header_forwarder is renamed to client.ip in version 0.16.1 of this integration. Hence please consider changing apache_tomcat.access.header_forwarder to client.ip field where it is being used. By using the Update By Query API, apache_tomcat.access.header_forwarder can be renamed to client.ip field for all the documents which would help to adapt this change.

  • In case of data ingestion if user encounter following errors then it is because of the rate limit of Prometheus endpoint. Here there won't be any data loss but if user still want to avoid it then make sure configured Prometheus endpoint is not being accessed from multiple places.

{
  "error": {
    "message": "unable to decode response from prometheus endpoint: error making http request: Get \"http://127.0.0.1/metrics\": dial tcp 127.0.0.1: connect: connection refused"
  }
}
  • If events are ingested with incorrect timestamps, kindly verify the Timezone setting for the Catalina and Localhost logs data streams on the 'Add Apache Tomcat' page.

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.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
Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), event.module should contain the name of this module.
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
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.request.referrer
Referrer for this HTTP request.
keyword
http.response.status_code
HTTP response status code.
long
http.version
HTTP version.

log.file.idxlo
The low-order part of a unique identifier that is associated with a file. (Windows-only)
keyword
log.file.inode
Inode number of the log file.
keyword
log.file.vol
The serial number of the volume that contains a file. (Windows-only)
keyword
log.offset
Log offset.
long
related.ip
All of the IPs seen on your event.
ip
source.ip
IP address of the source (IPv4 or IPv6).
ip
tags
List of keywords used to tag each event.
keyword
url.extension
The field contains the file extension from the original request url, excluding the leading dot. The file extension is only set if it exists, as not every url has a file extension. The leading period must not be included. For example, the value must be "png", not ".png". Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz").
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.

Exported fields

FieldDescriptionType
@timestamp
Event timestamp.
date
apache_tomcat.localhost.subsystem
Indicates Apache Tomcat’s subsystem or the type of the module that was the source of the message. For example, RBPM or Java Messaging Service (JMS).
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
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
error.stack_trace
The stack trace of this error in plain text.
wildcard
error.stack_trace.text
Multi-field of error.stack_trace.
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.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
Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), event.module should contain the name of this module.
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.timezone
This field should be populated when the event's timestamp does not include timezone information already (e.g. default Syslog timestamps). It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00").
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
input.type
Type of Filebeat input.
keyword
log.file.device_id
ID of the device containing the filesystem where the file resides.
keyword
log.file.fingerprint
The sha256 fingerprint identity of the file when fingerprinting is enabled.
keyword
log.file.idxhi
The high-order part of a unique identifier that is associated with a file. (Windows-only)
keyword
log.file.idxlo
The low-order part of a unique identifier that is associated with a file. (Windows-only)
keyword
log.file.inode
Inode number of the log file.
keyword
log.file.vol
The serial number of the volume that contains a file. (Windows-only)
keyword
log.level
Original log level of the log event. If the source of the event provides a log level or textual severity, this is the one that goes in log.level. If your source doesn't specify one, you may put your event transport's severity here (e.g. Syslog severity). Some examples are warn, err, i, informational.
keyword
log.offset
Log offset.
long
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
tags
List of keywords used to tag each event.
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.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
Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), event.module should contain the name of this module.
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.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
service.address
Address where data about this service was collected from. This should be a URI, network address (ipv4:port or [ipv6]:port) or a resource path (sockets).

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.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
Name of the module this data is coming from. If your monitoring agent supports the concept of modules or plugins to process events of a given source (e.g. Apache logs), event.module should contain the name of this module.
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.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
service.address
Address where data about this service was collected from. This should be a URI, network address (ipv4:port or [ipv6]:port) or a resource path (sockets).
keyword
tags
List of keywords used to tag each event.
keyword
