Ceph storage

Supported by Dynatrace

This extension provides ability to monitor usage of Ceph storage system. It covers both client side and host level in-depth data.

This is intended for users, who:

Would like to monitor usage and performance of their Ceph platform.
Require constant ability to have live information about host resources and data flow.
Aim to shorten analysis time, required to find out root cause of possible system failures, to the minimum.

use cases

This enables you to:

Monitor host resources usage and its capacity levels.
Collect data regarding active and inactive Ceph object storage daemons.
Observe system data flow in terms of write/read operations, for the cluster as a whole, and for the osd's in particular.

Environment with Ceph storage deployed

The only thing required is to have an environment with Ceph storage running
