NetApp Filers: Used space of aggregations
|Distribution:||official part of Check_MK|
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_api_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.
Name of the aggregation as defined in the system
All local aggregations are automatically inventorized.
