NetApp Filers: Used space and traffic of volumes

Distribution: official part of Check_MK
License: GPL
Supported Agents: NETAPP

This check measures the usage of volumes. The usage is checked against a warning and a critical level, which can be specified in numerous ways.

Trends: This checks supports volume trends. This means that the netapp_api_volumes check is able to compute the change of the used space over the time and can make a forecast into the future. It can estimate the time when the volume will be full.

In the default configuration the check will compute the trend based on the data of the last 24 hours using a logarithmic average that gives more recent data a higher weight. Also data beyond the 24 hours will to some small degree be reflected in the computation. The advantage of this algorithm is a more precise prediction and a simpler implementation, which does not need any access to any RRDs or similar storage.

Please note that when a volume is started to be monitored, the trend of the past is unknown and is assumed to be zero. It will take at least one trend range of time until the trend approximately reflects the reality.

You can also enable performance data for the traffic and latency for specific protocols (global, nfs, cifs, san, fcp, iscsi) via the parameters
