+Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.
 
 The plugin works by scanning the configured SocketDir for OSD and MON socket files.  When it finds
-a MON socket, it runs **ceph --admin-daemon $file perfcounters_dump**. For OSDs it runs **ceph --admin-daemon $file perf dump** 
+a MON socket, it runs **ceph --admin-daemon $file perfcounters_dump**. For OSDs it runs **ceph --admin-daemon $file perf dump**
 
 The resulting JSON is parsed and grouped into collections, based on top-level key.  Top-level keys are
 used as collection tags, and all sub-keys are flattened. For example:
