How to generate a line chart for disk space by server and hard drive?

New Member

I'm new to Splunk and need some help with a chart for disk space usage. I'm getting the data already in Splunk Light and would like to do a line chart that displays ALL servers and ALL drives in the same chart.

Thanks for your help.

Depends upon what you want to plot as x-axis value and what as series, try something like this (check the sourcetype name is correct or not)

host on x-axis, and one line for each drive

index=foo sourcetype="Perfmon:Logical Disk" 
| chart avg(Value) over host by instance limit=0

drive on x-axis, and one line for each host

index=foo sourcetype="Perfmon:Logical Disk" 
| chart avg(Value) over instance by host limit=0 | rename instance as drive

Regular events from perfmon for example:

collection="Free Disk Space"
object=LogicalDisk
counter="% Free Space"
instance=C:
Value=30.601598715187794
host = server1

collection="Free Disk Space"
object=LogicalDisk
counter="% Free Space"
instance=C:
Value=63.5187794
host = server2

server1 has 3 drive letters C:, E:, F:.
server 2 has 1 drive letter C:
server 3 has 3 drive letters C:, D:, E:
