NetApp Filer: Used Space of Aggregations

Distribution	Official part of Checkmk
Lizenz	GPLv2
Unterstützte Agenten	Netapp

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

Trends: This checks supports aggregation trends. This means that the netapp_ontap_aggr 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 aggregation 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 aggregation 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.

Item

Name of the aggregation as defined in the system

Discovery

One service is created for each {local} aggregation.
