logstash-output-datadog_logs

DatadogLogs lets you send logs to Datadog based on LogStash events.

Requirements

The plugin relies upon the zlib library for compressing data. Successfully tested with Logstash 6.x, 7.x and 8.x.

How to install it?

logstash-plugin install logstash-output-datadog_logs

How to use it?

The datadog_logs plugin is configured by default to send logs to a US endpoint over an SSL-encrypted HTTP connection. The logs are by default batched and compressed.

Configure the plugin with your Datadog API key:

output {
    datadog_logs {
        api_key => "<DATADOG_API_KEY>"
    }
}

To enable TCP forwarding, configure your forwarder with:

output {
    datadog_logs {
        api_key => "<DATADOG_API_KEY>"
        host => "tcp-intake.logs.datadoghq.com"
        port => 10516
        use_http => false
    }
}

To send logs to the Datadog's EU HTTP endpoint, override the default host

output {
    datadog_logs {
        api_key => "<DATADOG_API_KEY>"
        host => "http-intake.logs.datadoghq.eu"
    }
}

Add metadata to your logs

In order to get the best use out of your logs in Datadog, it is important to have the proper metadata associated with them (including hostname, service and source). To add those to your logs, add them into your logs with a mutate filter:

filter {
  mutate {
    add_field => {
      "host"     => "<HOST>"
      "service"  => "<SERVICE>"
      "ddsource" => "<MY_SOURCE_VALUE>"
      "ddtags"   => "<KEY1:VALUE1>,<KEY2:VALUE2>"
    }
  }
}
