SensuPluginsZFS

Sensu plugin for zfs health checks.

Checks

check-zpool.rb

This checks does the following checks against one or more zpools.

• Check state
• Check vdev errors
• Check capacity
• Check that a scrub has been run recently

The following flags can be used to configure the checks.

• -z, --zpool What zpool to check. If omitted, we check all zpools.
• -c, --capacity-warn Capacity threshold for when to warn. (default 80)
• -C, --capacity-crit Capacity threshold for when to crit. (default 90)
• -s, --scrubbing-interval Warn when it is more than this number of days since last scrub. (default 7)

Metrics

metric-zfs-arc.rb

Reads /proc/spl/kstat/zfs/arcstats for ARC statistics and puts them in a form usable by Graphite.

Contributing

At this time ideas for additional checks/metrics would be very much appreciated.

I have a few ideas that would be nice:

• Check for zpool state
• Check for vdev errors
• Check for pool capacity
• Check that disks have been scrubbed recently
• Metric for disk utilization
