Netapp Cluster Monitoring Beta

The title pretty much says it all! Today I’ll be releasing the beta for Netapp C-Mode monitoring and I hate to admit it’s not my best work… there are a large number of ways it could be improved but my time constraints for getting this particular job done were more narrow than I would have otherwise liked. This was compounded by having to wrestle with a number of bugs or strange quirks with Netapp Ontapi which caused some rather bizarre behaviour.

Included in this release will be monitoring of the following:

  • Volume health (percent disk used, disk space remaining, percent inodes used, inodes remaining, offline)
  • Aggregate health (percent disk used, disk space remaining, percent inodes used, inodes remaining, offline, is on home node)
  • Snapshot health (percent disk used, disk space remaining, percent inodes used, inodes remaining, offline)
  • Snapmirror relationship health (health and lag time)
  • Filer hardware health (fan, psu, temperature, battery)
  • Interface health (Physical or LIF is on home node and in the configured state)
  • Generic netapp alarms
  • Cluster health (Various conditions pertaining to cluster problems)
  • Disk health (Disk error flags)

This functionality has been 50% tested and very large clusters will encounter problems with the volume and snapshot monitoring… this should be rectified on the next release. I also expect that future versions may not be backwards compatible with this version when upgrading though I will endeavor to make sure the transition to future versions will be easy as possible.

I hope despite the current rickety state of the plugin that it helps some people 🙂
