We want gluster's monitoring/observability to be as easy as possible going forward. As part of reaching this goal we are starting this initiative to add improvements to existing apis/commands and create new apis/commands to gluster so that the admin can integrate it with whichever monitoring tool he/she likes. The gluster-prometheus project hosted at https://github.com/gluster/gluster-prometheus is the direction in which we feel metrics can be collected and distributed from a Gluster cluster enabling analysis and visualization.


As a first step we want to hear from you what you feel needs to be addressed.

Regarding monitoring; I would love to see in my monitoring that geo-replication is working as intended; at the moment I'm faking georep monitoring by having a process touch a file (every server involved in gluster touches another file) on every volume and checking mtime on the slave.

However, I discovered that this is not foolproof: if the georep run stops for whatever reason the mtime of the monitored file is being kept updated, probably because it's updated to often, but the georep is not complete.

I've also seen that a crashed glusterd escapes this monitoring.



What would also be fun is some kind of monitoring where you can find out why gluster is running at X MB/sec where Y MB/sec is expected (bit large target, that)



I've once tried monitoring 'gluster volume status all' output but that only works if everything is OK; with some network problems you can wait for hours for output which then causes more problems.



Also, I've checked the example output at https://github.com/gluster/gluster-prometheus:

would JSON or something like that be more friendy to parse instead of the "[parameter] { [details] } [number]" format?

thanks,
Maarten.
