Is it possible either using OCI or OCUM to create a report that would show uptime of a particular storage node? I need to report on this for SLA's. I know it is not as simple as some would make it out to be because there are many things that can affect whether an application actually sees it's storage, but for starters I am thinking we could just report on uptime of the nodes. In a quick look though I am not seeing that as something I could easily report on from OCI or OCUM and want to see if it is even possible before I waste any more time.
I no longer know OCUM well enough to say whether it would have the data or not.
ASUP used to have this as a key metric, so it is probably in ActiveIQ somewhere. It was based on analysis of logs after restart events. If you use ASUP/ActiveIQ, that may be your easiest path to reporting this metric.
