I received the following question:
If we understand correctly, the blog entry and the microdelta_example.cfg explain that the parameter –delta=10 [–tolerance=5] overrides the interval (e.g 3 mins) set by the getter by collecting the data twice during the 3 minutes?!
That is not entirely true. The switch …
Sometimes it is not possible to identify volumes that accommodate a LUN by name only - for instance, if there is no apparent naming convention or if the names doesn’t give any indication of this fact. In such cases, it can be quite tedious to configure the checks for volume usage because the thresholds for LUN …
Host adapter such as 0a/0b (Fibre Channel, Serial Attached SCSI and parallel SCSI) can now be monitored in the same way that network adapters can be monitored using PerfLif and PerIf. This check is called PerfHostadapter . Example: $ ./ check_netapp_pro.pl PerfHostadapter -H sim83n1 NETAPP_PRO PERFHOSTADAPTER CRITICAL …
Up until now aggregates and volumes could be monitored in order to determine their disk usage. The Usage check was designed for this purpose and can be easily configured to fit your needs. However, there was no way of predicting when an aggregate would reach a critical level, or in other words, how many days it would …
Microdeltas is an experimental feature for measuring performance with a resolution smaller than 3 minutes. In the next release of Monitoring Plugins for NetApp, we introduce a new feature that provides ways to measure performance with very small deltas (in the time scale of seconds). All you have to do is set a …
For obvious reasons, the first checks that we developed primarily monitored volumes and aggregates. The overall method took the approach of sending an UNKOWN alarm if no volumes or aggregates could be found – since it is very unusual to find a filer without any aggregates or volumes. The same overall library was then …
Today we announce a new check NetInterface which monitors the Is-Home flag of a network interface and sends an alarm if current-port differs from home-port. This enables us to monitor the output of the following CLI command in a continuous and automated way:
clu1::> network interface show -is-home false Logical …
Since support for version 2.x will run out at the end of 2015, a number of checks that have not been replaced yet in the new version check_netapp_pro (3.x) will no longer be available: e.g. Hardware check, which has only been replaced partially (for instance, by Disk ). Now, with check_netapp7_head.pl, it is possible …
In order to verify a filer’s _system health status, _we now provide a new check: check_netapp_health.pl. It returns a warning message if the status of Seven and Cluster Mode filers deviates from “OK”. $ ./check_netapp_health.pl -H your-filer OK - system health status is ok. This check is included in …
Up until now, the Disk Check was used to inspect the failed (or offline) attribute of disks. Unfortunately in cluster mode, this caused disks that did not belong to an aggregate to be skipped and thus not to be checked. Therefore, we have extended the check as follows:
Failed disks will always be reported as such, …
