CEPH collector

Monitors the ceph cluster usage and consumption data of a server, and produces:

• Cluster statistics (usage, available, latency, objects, read/write rate)
• OSD usage
• OSD latency
• Pool usage
• Pool read/write operations
• Pool read/write rate
• number of objects per pool

Requirements

• rados python module
• Granting read permissions to ceph group from keyring file

# chmod 640 /etc/ceph/ceph.client.admin.keyring

Configuration

Edit the python.d/ceph.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/ceph.conf

Sample:

local:
  config_file: '/etc/ceph/ceph.conf'
  keyring_file: '/etc/ceph/ceph.client.admin.keyring'

Troubleshooting

To troubleshoot issues with the ceph module, run the python.d.plugin with the debug option enabled. The output will give you the output of the data collection job or error messages on why the collector isn't working.

First, navigate to your plugins directory, usually they are located under /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata

Now you can manually run the ceph module in debug mode:

./python.d.plugin ceph debug trace
