Getting Drive Specific Disk space information from hosts

I am using the universal forwarder on Windows Servers as I thought it would gather the needed information. However, it seems it only reports total disk space, _total, and not on the individual drives. Is there a way I can capture individual drives with perfmon or should I revert to WMI polling, which is a pain in our envrironment due to getting a service AD account?

If I have to switch to WMI polling is there any point in leaving the universal forwarder on the windows servers to collect information?

Any help would be appreciated.

I found out you need to enable the counter in perfmon in the perfmon.conf file in etc/system/local on the host. I added the following and I was able to get perfmon to work.

[PERFMON:FreeDiskSpace]
counters = Free Megabytes;% Free Space
disabled = 0
instances = *
interval = 10
object = LogicalDisk

This worked for me!

index=perfstats sourcetype=PerfmonMk* host=servername C | timechart avg("%_Free_Space") by host

dar104,

I tried what you suggested, and I am not seeing results by drive letter. Can you contact me to discuss? I'd like to know better what to expect.

Yes!
You can get the UF to do the polling for your, assuming it is running under an account with admin permissions. I used to use a VBS script to perform the WMI query locally and the results of the query would be forwarded onto the indexer, a nice simple way to achieve what you want.

All I was getting from the forwarder was total disk space % instead of individual drives. I think I figured out a solution. I am testing now. If it works I will put results here.

Thanks for the response.
