One of the most innovative features of check_netapp_pro is probably the option -rm_ack, which solves the problem of errors not being alarmed for confirmed overall checks. These errors will not be alarmed actively and can therefore be easily overlooked. This switch might soon be replaced by another, more sophisticated …
Our new check PerfAggregate measures various performance counters per aggregate. Currently, the following counters can be monitored:
aggr_throughput (B/s) latency (µs) read_data (B/s) total_transfers (/s) total_transfers_hdd (/s) total_transfers_ssd (/s) transmit_failure (-) user_read_blocks (/s) user_read_latency (us) …

Example:``` $ check_netapp_takeover.pl -H filer01f NETAPP_TAKEOVER OK node filer0101 connected (ha mode): The the storage failover facility is enabled. Takeover of …

Until now this check measured the size in bytes. From now on we have an additional argument ‑‑what=size|inodes. Setting this argument to inodes tells the …
Obviously, one of the first plugins that we implemented was designed to monitor volumes and aggregates and their respective usage (“how many bytes are still available”). This plugin is called Usage and from the get-go it could monitor disk space usage in bytes as well as the number available (or used) …
