I had the follow data
index=os sourcetype=top host=xxxxxxx
| search COMMAND = "startWebworksAd" OR COMMAND="startWLSServer" OR COMMAND="startManagedWeb" OR COMMAND="launch.sh"
| table host, COMMAND
This data is based on top command on linux so if the process is not running so into the splunk the process will not have data been updating, I whish list the process on the query even when this situation occur count line by line and when not found they list as 0
