Collector Architecture

Our present monitoring-plugin for NetApp FAS devices, named check_netapp_pro is based on the so-called collector architecture. This allows us to monitor even the most complex storage-systems like Fabric Metro Clusters. The collector architecture works as follows: Collectors are distinct scripts that collect all the data that the checks require and saves it in a Store on the Nagios Server. The checks have access to the Store and no longer contact the NetApp devices themselves.

check_netapp_pro: What's New in Version 3.0.7

Version 3.0.7 of our Monitoring Plugins for NetApp (check_netapp_pro) will be available soon and will include a number of new features that have been implemented based on feedback we received from our customers: New Check PerfSys: Not entirely new, but taken over from the stable version 2.x to version 3.x. In this new release, system-wide performance counters such as transfer-rate or _operations per second _ can also be checked on cluster mode Filers.

Mammamia!

To facilitate communication between users and developers, we are introducing a new switch: --mammamia The idea behind this switch: advanced users that want to test a script or a function which appears not to be working properly usually switch to the command line. Should they require the assistance of the developer, they previously had to include the output of the script in an email. In most cases, this was not enough and resulted in more requests from the developer such as: creating and sending rawdump, creating and sending verbose output – annoying!

PerfVolume – More Counter, Better Performance

The new version of **PerfVolume **is now able to handle any amount of volumes on a filer. The formerly common error message “Not enough memory to get instances” is a thing of the past. Should the amount of instances exceed the maximum possible value, the plugin would start a second call at runtime in order to collect the missing instances. The core task of the PerfVolume check has remained the same: continuous monitoring of latency (per volume latency) on NetApp filers.

rm_ack – an innovative Switch with the additional touch

The abbreviation rm_ack stands for remove service acknowledgement, which refers to a rather simple algorithm that can be used to identify masked alarms. Masked alarms are a phenomenon that solely appears with checks on multiple instances, such as the simultaneous checking of all volumes on a NetApp device. In a nutshell, during such a check, it can happen that a critical service check in Nagios gets acknowledged (Service Acknowledgement) because of a specific volume.

Nagios Plugins for Clustermode NetApp

Half a year ago there was very little demand for Nagios plugins that support Cluster Mode. Recently, we have received more and more requests for just such plugins. We are looking at Q4 2013 to launch our new release of Nagios Plugins for NetApp, Version 3.0, with added support for cluster mode. http://www.netapp-monitoring.info/en/matrix_check_netapp_pro.html
