Overview
Ceph is a framework for distributed storage clusters. The frontend client framework is based on RADOS (Reliable Autonomic Distributed Object Store). Clients can directly access Ceph storage clusters with librados, but also can use RADOSGW (object storage), RBD (block storage), and CephFS (file storage). The backend server framework consists of several daemons that manage nodes, and backend object stores to store user's actual data.
Use the Ceph integration to:
- Collect metrics related to the cluster disk, cluster health, cluster status, Object Storage Daemons (OSD) performance, Object Storage Daemons (OSD) pool stats, Object Storage Daemons (OSD) tree and pool disk.
- Create visualizations to monitor, measure and analyze the usage trend and key data, and derive business insights.
- Create alerts to reduce the MTTD and also the MTTR by referencing relevant logs when troubleshooting an issue.
Data streams
The Ceph integration collects metrics data.
Metrics give you insight into the statistics of the Ceph. The Metric data streams collected by the Ceph integration are cluster_disk
, cluster_health
, cluster_status
, osd_performance
, osd_pool_stats
, osd_tree
and pool_disk
, so that the user can monitor and troubleshoot the performance of the Ceph instance.
Data streams:
cluster_disk
: Collects information related to overall storage of the cluster.cluster_health
: Collects information related to health of the cluster.cluster_status
: Collects information related to status of the cluster.osd_performance
: Collects information related to Object Storage Daemons (OSD) performance.osd_pool_stats
: Collects information related to client I/O rates.osd_tree
: Collects information related to structure of the Object Storage Daemons (OSD) tree.pool_disk
: Collects information related to memory of each pool.
Note:
- Users can monitor and see the metrics inside the ingested documents for Ceph in the
logs-*
index pattern fromDiscover
.
Compatibility
This integration has been tested against Ceph 15.2.17 (Octopus)
and 14.2.22 (Nautilus)
.
In order to find out the Ceph version of your instance, see following approaches:
-
On the Ceph Dashboard, in the top right corner of the screen, go to
Help
>About
. You can see the version of Ceph. -
Please run the following command from Ceph instance:
ceph version
- The
ceph-rest-api
tool has been deprecated and dropped from Ceph versionMimic
onwards. Please refer here: https://docs.ceph.com/en/latest/releases/luminous/#id32
Prerequisites
You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended or self-manage the Elastic Stack on your own hardware.
In order to ingest data from the Ceph, user must have
- Enable RESTful module. Refer: https://docs.ceph.com/en/octopus/mgr/restful/#restful-module
- Create API keys to allow users to perform API key authentication. To create API User and API Secret Key, please refer https://docs.ceph.com/en/octopus/mgr/restful/#creating-an-api-user
Setup
For step-by-step instructions on how to set up an integration, see the Getting started guide.
Configuration
You need the following information from your Ceph instance
to configure this integration in Elastic:
Ceph Hostname
Host Configuration Format: http[s]://<ceph-mgr>:<port>
Example Host Configuration: https://127.0.0.1:8003
API User and API Secret Key
To list all of your API keys, please run the following command from Ceph instance:
ceph restful list-keys
The ceph restful list-keys command will output in JSON:
{
"api": "52dffd92-a103-4a10-bfce-5b60f48f764e"
}
In the above JSON, please consider api
as API User and value of 52dffd92-a103-4a10-bfce-5b60f48f764e
as API Secret Key while configuring an integration.
Validation
After the integration is successfully configured, clicking on the Assets tab of the Ceph Integration should display a list of available dashboards. Click on the dashboard available for your configured data stream. It should be populated with the required data.
Troubleshooting
- If
host.ip
appears conflicted under thelogs-*
data view, this issue can be resolved by reindexing theCluster Disk
,Cluster health
,Cluster Status
,OSD Performance
,OSD Pool Stats
,OSD Tree
andPool Disk
data streams.

OSD Tree
This is the osd_tree
data stream. This data stream collects metrics related to Object Storage Daemon (OSD) tree id, name, status, exists, crush_weight, etc.
An example event for osd_tree

ECS Field Reference
Please refer to the following document for detailed information on ECS fields.
Exported fields
Field | Description | Type | Metric Type |
---|---|---|---|
@timestamp | Event timestamp. | date | |
ceph.osd_tree.children | Bucket children list, separated by a comma. | keyword | |
ceph.osd_tree.crush_weight | CRUSH buckets reflect the sum of the weights of the buckets or the devices they contain. For example, a rack containing a two hosts with two OSDs each, might have a weight of 4.0 and each host a weight of 2.0. The sum for each OSD, where the weight per OSD is 1.00. | float | gauge |
ceph.osd_tree.depth | Depth of OSD node. | long | |
ceph.osd_tree.device_class | The device class of OSD. i.e. hdd, ssd etc. | keyword | |
ceph.osd_tree.exists | Represent OSD node still exist or not (1-true, 0-false). | boolean | |
ceph.osd_tree.node_osd_id | OSD or bucket node id. | long | |
ceph.osd_tree.node_osd_name | OSD or bucket node name. | keyword | |
ceph.osd_tree.primary_affinity.count | The weight of reading data from primary OSD. | float | gauge |
ceph.osd_tree.reweight | OSD reweight sets an override weight on the OSD. This value is in the range 0 to 1, and forces CRUSH to re-place (1-weight) of the data that would otherwise live on the drive. | float | |
ceph.osd_tree.status | Status of the OSD, it should be up or down. | keyword | |
ceph.osd_tree.type.id | OSD or bucket node typeID. | long | |
ceph.osd_tree.type.name | OSD or bucket node type, illegal type include osd, host, root etc. | keyword | |
data_stream.dataset | Data stream dataset. | constant_keyword | |
data_stream.namespace | Data stream namespace. | constant_keyword | |
data_stream.type | Data stream type. | constant_keyword | |
input.type | Type of Filebeat input. | keyword |
