I've installed the 6.3.4 forwarder on a Windows 2008 r2. It's got the Splunk Add-on for Microsoft Windows and perfmon enabled, but no perfmon memory is coming across. I'm thinking it's an OS problem. It is enabled and the forwarder has been restarted several times. It's grabbing Perfmon: PhysicalDisk/CPU/Network, etc, but no Memory.
inputs.conf
## Memory
[perfmon://Memory]
counters = *
disabled = 0
interval = 60
object = Memory
I'm having the same issue.
Here is what I use in my environment:
[perfmon://Memory]
useEnglishOnly=true
showZeroValue = 1
instances = *
object = Memory
counters = % Committed Bytes In Use; Available MBytes; Pages Input/sec;Free System Page Table Entries;Pages/sec
interval = 60
disabled = 0
Also, if you think it is an OS problem... Have you simply try to use perfmon directly to confirm the related counters still work as expected ?
