Got that full path added. Now I'm getting this error: System.Exception: An error occurred during log collection: ArcGIS Log Query Error: Invalid token, ClientID does not match. StatusCode: 498 at ESRI.PS.EIST.SystemLogParser_Plus.CLI.StartHere.Main(String args)
Instead of using my server domain name, I tried using my server's elastic ip address and that worked!! Thanks for your help.
