+.. _prometheus-rbd-io-statistics:
+
RBD IO statistics
-----------------
of ``pool[/namespace]`` entries. If the namespace is not specified the
statistics are collected for all namespaces in the pool.
+Example to activate the RBD-enabled pools ``pool1``, ``pool2`` and ``poolN``::
+
+ ceph config set mgr mgr/prometheus/rbd_stats_pools "pool1,pool2,poolN"
+
The module makes the list of all available images scanning the specified
pools and namespaces and refreshes it periodically. The period is
configurable via the ``mgr/prometheus/rbd_stats_pools_refresh_interval``
force refresh earlier if it detects statistics from a previously unknown
RBD image.
+Example to turn up the sync interval to 10 minutes::
+
+ ceph config set mgr mgr/prometheus/rbd_stats_pools_refresh_interval 600
