Chapter 1. Introduction
The Datadog integration with Ceph allows Datadog to execute and process the output from:
-
ceph status -
ceph health detail -
ceph df detail -
ceph osd perf; and, -
ceph osd pool stats.
The integration enables Datadog to:
- Monitor the status and health of the Ceph Storage cluster
- Monitor I/O and performance metrics; and,
- Track disk usage across storage pools.
Using Datadog to monitor Ceph requires installing a Datadog agent on at least one Ceph monitor node. When monitoring Ceph, the Datadog agent will execute Ceph command line arguments. Consequently, each Ceph node must have an appropriate Ceph key providing access to the cluster, usually in /etc/ceph. Once the agent executes the Ceph command, it sends Ceph cluster status and statistics back to Datadog. Then, Datadog will present the status and statistics in the Datadog user interface.
Since Datadog uses an agent, the Ceph cluster must be able to reach the internet; however, the Ceph cluster does not have to be reachable from the internet.
Datadog supports retrieving ceph status with RHCS 2. Datadog will provide an update to support ceph status for RHCS 3 in a subsequent release of its dd-agent.
