[ClusterLabs] Cluster metrics and collectd

[Huw Davies]

I was wondering if anyone had looked into getting cluster metrics (counters and performance) and exposing them via collect?

We’re about to go live with a large application on a four node RHEL and are interested in understanding the cluster loads - this will help us decide whether it’s better to run everything on a couple of nodes or to spread out across the whole cluster.

Locking in particular we are concerned could be a bottleneck (it is in the current implementation on another clustering solution)
