Hello, This may come across as a simple question but just wanted to check. I am looking at importing live data from my cluster via ceph -s e.t.c into a graphical graph interface so I can monitor performance / iops / e.t.c overtime. I am looking to pull this data from one or more monitor nodes, when the data is retrieved for the ceph -s output is this information that the monitor already has locally or is there an overhead that is applied to the whole cluster to retrieve
this data every time the command is executed? Reason I ask is I want to make sure I am not applying unnecessary overhead and load onto all OSD node’s to retrieve this data at a near live view, I fully understand it will apply a small amount of load / CPU on the local MON to process
the command, I am more interesting in overall cluster. Thanks, Ashley |
