Lots of good info there, thank you!  I tend to get options fatigue when trying to pick out a new system.  This should help narrow that focus greatly.

Grafana is the web frontend for creating the graphs.

 

InfluxDB holds the time series data that Grafana pulls from.

 

To collect data, I am using collectd daemons running on each ceph node (mon,mds,osd), as this was my initial way of ingesting metrics.

I am also now using the influx plugin in ceph-mgr to have ceph-mgr directly report statistics to InfluxDB.

 

I know two other popular methods of collecting data are Telegraf and Prometheus, both of which are popular, both of which have ceph-mgr plugins as well here and here.

Influx Data also has a Grafana like graphing front end Chronograf, which some prefer to Grafana.

 

Hopefully thats enough to get you headed in the right direction.

I would recommend not going down the CollectD path, as the project doesn't move as quickly as Telegraf and Prometheus, and the majority of the metrics I am pulling from these days are provided from the ceph-mgr plugin.

 

Hope that helps,

Reed

Reed:  If you don’t mind me asking, what was the graphing tool you had in the post?  I am using the ceph health web panel right now but it doesn’t go that deep.
