|List of Plugins|
The NetApp plugin is a read plugin that connects to a NetApp storage system and queries various performance values from the system. Queried values include used / free disk space, read and write operations, network IO, and CPU utilization.
The plugin uses libnetapp, a library provided by NetApp, Inc., to connect to one or more filers and receive information. This way information is available that isn't provided via SNMP, for example snapshot statistics. Due to a wide variety of available statistics, it is possible to control very fine-grained which information to collect using the configuration. Each group of statistics can be collected in a separate interval, so that free / used disk space can be collected less often than, say, CPU utilization.
The plugin was written in 2009 by Sven Trenkel for the noris network AG and licensed under the MIT license.
This plugin is a generic plugin, i.e. it cannot work without configuration, because there is no reasonable default behavior. Please read the Plugin netapp section of the collectd.conf(5) manual page for an in-depth description of the plugin's configuration.

Used and free space in a volume. You can also see the amount of additional space available thanks to Single Instance Storage (SIS) by finding duplicate blocks. SIS began its very first run on this volume around 21:00 but all freed space was still in use by older snapshots. At around 0:00 the space reserved for snapshots was increased, at 11:30 these snapshots were deleted, causing “normal” space to be freed while some space remains reserved for snapshots.
- libnetapp, a library that is part of the Manage ONTAP SDK published by NetApp.
Netapp Configuration Required
This is an example configuration that has to be done on the filer before collectd can start collecting data via the API. A user with API access needs to be created, as stated above, but SSL also needs to be setup and enabled.
