Monitor Ceph: From node status to cluster-wide performance

Ceph is an open source distributed object store and file system designed for scalability, reliability, and performance. It provides an S3- and Openstack Swift–compatible API for storing, retrieving, and managing objects. Datadog can be used to monitor Ceph's operations and performance by providing cluster-level metrics, pool-level resolution, and node status information. This helps in identifying bottlenecks, provisioning resources appropriately, and maintaining the health of a running Ceph cluster.
