I would like to monitor parameters like
- cluster state of each node
- state of each node
- excessive replication conflicts
- excessive flow control conflicts
- large replication queues
in an XtraDB cluster (at the moment I don’t know if those are even possible) and I’m not quite yet at the point where I want to install the SeveralNinesCluster control tools as the cluster is production and therefore sacred.
I have already looked at the s9s nagios plugin but it seems to depend on tables which belong to the s9s-cluster control so that path is kinda blocked.
All suggestions are welcome.
