To monitor Logstash nodes:
Install X-Pack by running
bin/logstash-plugin installin the Logstash installation directory on each node you want to monitor:
bin/logstash-plugin install x-pack
The plugin install script requires direct Internet access to download and install X-Pack. If your Logstash node doesn’t have Internet access, manually download and install X-Pack. See Installing X-Pack.
Configure your Logstash nodes to send metrics to your Elasticsearch cluster by setting the
logstash.yml. If security is enabled, you also need to specify the credentials for the built-in
To visualize Logstash as part of the Stack (shown below in Step 5), send metrics to your production cluster. Sending metrics to a dedicated monitoring cluster will show the Logstash metrics under the monitoring cluster.
If SSL/TLS is enabled on the production cluster, you must connect through HTTPS. As of v5.2.1, you can specify multiple Elasticsearch hosts as an array as well as specifying a single host as a string. If multiple URLs are specified, Logstash can round-robin requests to these production nodes.
logstash_systemuser is automatically added when you install X-Pack. Don’t forget to change the default passwords for all of the built in users. If X-Pack security is disabled on the production cluster, you can omit the
passwordfor the agent.
If SSL/TLS is enabled on the production Elasticsearch cluster, specify the trusted CA certificate(s) that will be used to verify the identity of the nodes in the cluster.
To add a CA certificate to a Logstash node’s trusted certificates, you can specify the location of the PEM encoded certificate with the
Alternatively, you can configure trusted certificates using a truststore (a Java Keystore file that contains the certificates):
xpack.monitoring.elasticsearch.ssl.truststore.path: /path/to/file xpack.monitoring.elasticsearch.ssl.truststore.password: password
Also, optionally, you can set up client certificate using a keystore (a Java Keystore file that contains the certificate):
xpack.monitoring.elasticsearch.ssl.keystore.path: /path/to/file xpack.monitoring.elasticsearch.ssl.keystore.password: password
- Restart your Logstash nodes.
To verify your X-Pack monitoring configuration, point your web browser at your Kibana host, and select Monitoring from the side navigation. Metrics reported from your Logstash nodes should be visible in the Logstash section. When security is enabled, to view the monitoring dashboards you must log in to Kibana as a user who has the
When upgrading from older versions of X-Pack, the built-in
user is disabled for security reasons. To resume monitoring, change the password and re-enable the logstash_system user.
