A Logstash output plugin for sending logs to the Dynatrace Generic log ingest API v2. Please review the documentation for this API before using the plugin.

• Logstash 7.6+

Logstash is typically installed in the /usr/share/logstash directory, and plugins are installed using the /usr/share/logstash/bin/logstash-plugin command. If your logstash installation directory is different than this, your logstash-plugin command may be in a different location.

/usr/share/logstash/bin/logstash-plugin install logstash-output-dynatrace

See below for a detailed explanation of the options used in this example configuration.

output {
  dynatrace {
    id => "dynatrace_output"
    ingest_endpoint_url => "${ACTIVE_GATE_URL}/api/v2/logs/ingest"
    api_key => "${API_KEY}"
  }
}

The following configuration options are supported by the Dynatrace output plugin as well as the common options supported by all output plugins described below.

The following configuration options are supported by all output plugins:

• Value type is string
• Required

This is the full URL of the Generic log ingest API v2 endpoint on your ActiveGate. Example: "ingest_endpoint_url" => "https://abc123456.live.dynatrace.com/api/v2/logs/ingest"

• Value type is string
• Required

This is the Dynatrace API token which will be used to authenticate log ingest requests. It requires the logs.ingest (Ingest Logs) scope to be set and it is recommended to limit scope to only this one. Example: "api_key" => "dt0c01.4XLO3..."

• Value type is boolean
• Optional
• Default value is false

It is recommended to leave this optional configuration set to false unless absolutely required. Setting ssl_verify_none to true causes the output plugin to skip certificate verification when sending log ingest requests to SSL and TLS protected HTTPS endpoints. This option may be required if you are using a self-signed certificate, an expired certificate, or a certificate which was generated for a different domain than the one in use.

NOTE: Starting in plugin version 0.5.0, this option has no effect in versions of Logstash older than 8.1.0. If this functionality is required, it is recommended to update Logstash or stay at plugin version 0.4.x or older.

• Value type is boolean
• Default value is true

Disable or enable metric logging for this specific plugin instance. By default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

• Value type is string
• There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type. For example, if you have 2 dynatrace outputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
  dynatrace {
    id => "my_plugin_id"
  }
}

When troubleshooting, always try to reduce the configuration as much as possible. It is recommended to disable all plugins except the Dynatrace output plugin and a simple input plugin like the http input plugin in order to isolate problems caused by only the Dynatrace output plugin.

You can enable debug logging in one of several ways:

• Use the --log.level debug command line flag
• Configure the log4j2.properties file (usually in /etc/logstash) - More info here
• Use the logging API - details here
