CPU.sh is required to populate some of the dashboards in the unix app. Unfortunately, when I run cpu.sh manually nothing happens. How do I get this running. I'm using a vanilla install of centOS.
Well, Dimitri, it sounds like quite the problem. 🙂
You may want to make sure that the sysstat package, which includes sar, is installed. Cpu.sh has a dependency on that and unfortunately, until that's installed, you're stuck.
yum -y install sysstat
Once that's installed, restart Splunk and you'll be in good shape.
systat is only required for linux operating systems. For Solaris, the scripted inputs (top.sh, vmstat.sh, etc) should work with the solaris tools such as prstat, etc.
