As of version 1.1.9i9
Checkmk supports trends
. This means that
the df
check is now able to compute the change
of the used space over the time and can make a forecast into the future. It can estimate the point of time where the filesystem will be full.
In the default configuration the check will compute the trend based on the data of the last 24 hours. Similar like the CPU load this is done with a logarithmic average that weights the more recent time more than time farer away. 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 being monitored, then the trend of the past is unknown and will be assumed to be zero
. That means that it will take at least one trend range of time until the trend approximately reflects the reality.
Item
The name of the aggregate or volume on the NetAPP filer.
Discovery
One service is created for each filesystem the agent reports except mount points listed in {inventory_df_exclude_mountpoints} and filesystem types listed in {inventory_df_exclude_fs}. The Windows agent only reports fixed disks. The Linux agent reports filesystems that have a size and are not of type smbfs, tmpfs, cifs or nfs.
