I have some ubuntu VM's created in Azure, I have installed the Splunk Forwarder and Splunk Add On For Unix, on my main Splunk instance installed the Splunk App for Unix and set the server to listen and set things running, and it's kinda working, but not how I expected.
When I look for Hosts in Splunk App for Unix the servers are showing, and the disk space is being recorded, but nothing else is, no CPU or Memory which were the two indicators I wanted to monitor.
In the Splunk Add-on all options are enabled (including cpu.sh and vmstat.sh) and on the monitored server $SPLUNKHOME/etc/apps/SplunkTA_nix/local/inputs.conf everything has been set to both 1 and 0 (to double check my stupidity of 0/1 being false) but still nothing is shown for CPU and memory, is this a limitation of Azure or am I doing something wrong?
You can also toggle the
interval value to reduce frequency and thereby reducing data volume.
Although the TA itself uses scripts that run on the splunk cron. So it actually sounds like what you described is exactly how the TA works. The app itself doesn't collect data.
Did you try running the specific scripts referenced within the TAs to see if they cpu and other inputs are working at the source? I believe adding a
--debug could help as well.
