Do you have total and consumed disk space for all mounts available in Splunk?
What have you tried so far?
taking the information about disks from the SplunkTAnix you have the following informations:
that you can use to do all the comparisons you want.
e.g. the time distribution od UsePct in time so you could trace the UsePct data, something like this:
index=os sourcetype=df | multikv | timechart span=1h max(UsePct) AS perc By host
fields: size = 15T, mountedon = /stg UsePct =92%, Used=14T, Avail = 1.4T
the requirement is to have
for each mount, Size and Used space side-by-side column chart or any other chart at any given moment and trend, just for visualization.
I am getting it in table part using
| stats latest(Size) as "TotalStorage" by mount,Used | rename Used as UsedStorage
To have a time distribution, try something like this:
index=os sourcetype=df host=your_host | multikv | bin span=1h _time | stats latest(Size) AS "TotalStorage" latest(Used) AS Used latest(UsePct) AS UsePct by Filesystem _time
