AIX: Paging Information
This check measures the usage of paged AIX volumes.
The warning and critical for the usage can be configured.
You can also enable performance data for the traffic and latency
for specific protocols (global, nfs, cifs, san, fcp, iscsi) via the parameters.
The service goes
CRIT if the usage goes over
the configured warning/critical level
Trends: This checks supports volume
trends. This means that this 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
It will take at least one trend range of time until the trend
approximately reflects the reality.
Name of the volume as defined in the system
One service is created for each volume.
