Monitor Ceph

Decapod supports integration with various monitoring systems. By default, it uses an in-house tool called ceph-monitoring. You can also integrate Decapod with other tools, such as Prometheus through Telegraf. For a list of supported plugins, see Playbook plugins.

The ceph-monitoring tool collects statistics on the cluster state and monitors its performance by running particular scripts under the admin service.

To access the collected data:

1. Obtain the Decapod monitoring port. The port is the value of the DECAPOD_MONITORING_PORT environment variable and is 10001 by default.
2. Access the data using the obtained port and your credentials. For example, if you access Decapod using http://10.0.0.10:9999, the data will be served on http://10.0.0.10:10001.

If there is no information available about a recently deployed cluster, try again in 15 minutes. If the data is still not accessible, obtain the logs of the admin service:

$ docker-compose -p myprojectname logs admin
