Mapped and online LUNs can remain unused in a filer because a connected initiator is missing. With the NetApp-CLI, such LUNS can be detected by following these steps:
First, we look for initiator groups for which **all **initiators are not logged in.
node01::> lun igroup show -igroup \*group06\* -instance Vserver …
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) …
The newly published check_netapp_takeover has been enhanced to check the metro-cluster configuration too. All of these checks are done in one service-check. Example:``` $ check_netapp_takeover.pl -H filer01f NETAPP_TAKEOVER OK node filer0101 connected (ha mode): The the storage failover facility is enabled. Takeover of …
If you are checking your filer with the Snapshots plugin, you may get an error like: Can't call method "attr" on an undefined value at /opt/.../lib/nagios/plugins/check_netapp_pro/checks/Snapshots.pm line 289. The reason for this is, that the SnapDrive application creates flexclones, which are created, …
The Check UsageTrend can be used to interpolate the usage of a volume or aggregate into the future and send an alarm if it would get filled up within a given time. 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) …

We are currently working on a check that monitors AutoSupport events, i.e. a check that sends an alarm if a AutoSupport message could not be created or sent. The last 50 ASUP events are polled and an alarm is triggered for any message with a failed status (transmission failed oder collection failed). Here’s an …
The newest unstable release 3.9.2_04 is now available in the Q-portal. It includes the following changes:
