Export metrics from your Ceph clusters to your Prometheus monitoring system.
You'll need a working Ceph cluster, and a working Prometheus server. Setup and installation of those is left as an exercise to the reader.
The server that you run this exporter needs to be configured to access
the Ceph cluster as a client. If you can run ceph status and get a
reasonable response you are good to go. It does not need to be run
on a server that is running other Ceph services, although there is
nothing preventing that. The server running the exporter service will
also need to be accessible from the Prometheus server.
The exporter service is developed and tested using Python 3. Running the service with Python 2 is untested.
virtualenv --python=/usr/bin/python3 /opt/ceph_exporter
/opt/ceph_exporter/bin/pip install git+https://github.com/jcollie/ceph_exporter.git
cp /opt/ceph_exporter/etc/ceph_exporter.service /etc/systemd/system
systemctl daemon-reload
systemctl enable ceph_exporter
systemctl start ceph_exporterThe Ceph exporter is configured using command line options:
usage: ceph_exporter.py [-h] [--config CONFIG] [--name NAME]
[--keyring KEYRING] [--endpoint ENDPOINT]
[--executable EXECUTABLE]
optional arguments:
-h, --help show this help message and exit
--config CONFIG Ceph config file location, default is
`/etc/ceph/ceph.conf`
--name NAME Ceph client name used to authenticate to the Ceph
cluster, default is `client.admin`
--keyring KEYRING Name of the file that contains key for authentication
with the Ceph cluster, default is
`/etc/ceph/ceph.client.admin.keyring`
--endpoint ENDPOINT Twisted server endpoint specifier, default is
`tcp:9192`
--executable EXECUTABLE
Path to the Ceph command line client executable,
default is `/usr/bin/ceph`
Twisted server endpoint specifiers are described here.
Multiple Ceph clusters could be monitored by copying the systemd
service file to a new name and pointing the exporter to different
configuration files.
Add a job to your Promethus configuration that looks like the following:
scrape_configs:
- job_name: 'ceph'
scrape_interval: 30s
scrape_timeout: 10s
target_groups:
- targets:
- 'localhost:9192'
