Ceph integration for Grafana Cloud
Ceph uniquely delivers object, block, and file storage in one unified system.
This integration includes 6 useful alerts and 1 pre-built dashboard to help monitor and visualize Ceph metrics.
Before you begin
In order for the Ceph integration to work, you must enable the built-in Prometheus plugin in your Ceph cluster, with the provided command:
ceph mgr module enable prometheus
Install Ceph integration for Grafana Cloud
- In your Grafana Cloud stack, click Connections in the left-hand menu.
- Find Ceph and click its tile to open the integration.
- Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Ceph metrics to your Grafana Cloud instance.
- Click Install to add this integration’s pre-built dashboard and alerts to your Grafana Cloud instance, and you can start monitoring your Ceph setup.
Post-install configuration for the Ceph integration
After enabling the prometheus plugin, instruct Grafana Agent to scrape your Ceph nodes.
Ceph exposes a
/metrics endpoint. To scrape it, add the provided snippet to your agent configuration file.
ceph_cluster label must be added to each scrape, such as the snippet. This is used as a filter in the dashboards, so you can monitor your nodes by cluster. Make sure to give it a value according to your environment.
Make sure to change
targets in the snippet according to your environment.
Configuration snippets for Grafana Agent
metrics.configs.scrape_configs, insert the following lines and change the URLs according to your environment:
- job_name: integrations/ceph # one job per node relabel_configs: - replacement: '<your-instance-name>' target_label: instance static_configs: - targets: ['cephnode1:9283'] labels: ceph_cluster: 'my-cluster'
Full example configuration for Grafana Agent
Refer to the following Grafana Agent configuration for a complete example that contains all the snippets used for the Ceph integration. This example also includes metrics that are sent to monitor your Grafana Agent instance.

The Ceph integration installs the following dashboards in your Grafana Cloud instance to help monitor your system.
- Ceph - Cluster
The Ceph integration includes the following useful alerts:
|CephUnhealthyWarining||Warning: The Ceph cluster has warning level issues|
|CephUnhealthyCritical||Critical: The Ceph cluster has critical issues|
|CephDiskLessThan15Left||Warning: The Ceph cluster has less than 15% storage space left|
|CephDiskLessThan5Left||Critical: The Ceph cluster has less than 5% storage space left|
|OSDNodeDown||Warning: The OSD node is down|
|MDSDown||Warning: All MDS nodes down|
The most important metrics provided by the Ceph integration, which are used on the pre-built dashboard and Prometheus alerts, are as follows:
# 0.0.6 - September 2023 * Update Grafana Agent configuration snippets to include filtered metrics used in gauge panels # 0.0.5 - September 2023 * New Filter Metrics option for configuring the Grafana Agent, which saves on metrics cost by dropping any metric not used by this integration. Beware that anything custom built using metrics that are not on the snippet will stop working. * New hostname relabel option, which applies the instance name you write on the text box to the Grafana Agent configuration snippets, making it easier and less error prone to configure this mandatory label. # 0.0.4 - September 2022 * Update panels descriptions. # 0.0.3 - April 2022 * Update mixin to latest version: - Removes all cluster variable in favor of `ceph_cluster` - Removes `node_exporter` based panels - Migrates from graph panel to time series panels - Removes panel stacking - Fixes `CephUnhealthy` alert - spliting into 2 different alerts with Warning and Critical levels - Sets default time threshold to 5m on all alerts # 0.0.2 - October 2021 * Update all rate queries to use `$__rate_interval`, so they respect the default resolution # 0.0.1 - August 2021 * Initial release
By connecting your Ceph instance to Grafana Cloud, you might incur charges. To view information on the number of active series that your Grafana Cloud account uses for metrics included in each Cloud tier, see Active series and dpm usage and Cloud tier pricing.
