+# ceph
+
+This module monitors the ceph cluster usage and consuption data of a server.
+
+It 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
+```shell
+# chmod 640 /etc/ceph/ceph.client.admin.keyring
+```
+
+### Configuration
+
+Sample:
+```yaml
+local:
+ config_file: '/etc/ceph/ceph.conf'
+ keyring_file: '/etc/ceph/ceph.client.admin.keyring'
+```

+# netdata python.d.plugin configuration for ceph stats
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 10
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 10 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# retries: 60 # the JOB's number of restoration attempts
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, ceph plugin also supports the following:
+#
+# config_file: 'config_file' # Ceph config file.
+# keyring_file: 'keyring_file' # Ceph keyring file. netdata user must be added into ceph group
+# # and keyring file must be read group permission.
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+#
+config_file: '/etc/ceph/ceph.conf'
+keyring_file: '/etc/ceph/ceph.client.admin.keyring'
+
