disk usage, splunk add on unix

sreesh — Thu, 21 May 2020 15:05:59 GMT

Would like to have chart of the total disk space vs used for all mounts at the current time for a host for comparison.

Would like to have trend chart of the total disk space vs used for all mounts for a host for comparison.

Any suggestions?

Do you have total and consumed disk space for all mounts available in Splunk?
What have you tried so far?

Hi
taking the information about disks from the Splunk_TA_nix you have the following informations:

Filesystem
Type
Size
Used
Avail
UsePct
MountedOn

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

Ciao.
