Command line graph execution on Linux

Is there a way to execute a graph on Linux on the commercial Clover Server product? I have a cron script that I'd like to be able to execute a graph when it finishes. I've seen many references to the command line capability, but I don't see any mention in the documentation so I have no clue where to start.

Thanks,
Andrew

  Hi Andrew,
  
  You can utilize Simple HTTP API, namely operation "graph_run". You can invoke such URL using curl, wget, or similar tool from your Cron script.
  
  You probably know that, but just for sure - Server contains Cron-like scheduler internally - Scheduling. So I guess you have some special requirement to use system-wide Cron.
  
  I hope this helps.

  I'm using a cron job because I can't get shell commands to work when Clover runs them due to the user (tomcat) that Clover runs as. If I could specify a different account for Clover to use when it runs the shell commands, I would be good.

  Hi,
  
  Unfortunately Server can execute scripts only under Tomcat account. What you can do:
  
  

  
  
  • Use commandline like su - user2 -c "/path/myscript.sh" but that would need password. You can omit password by http://unix.stackexchange.com/questions ... t-password
  
  
  • Use sudo and allow user to execute specific command without password in sudoers
  
  
  • Try http://www.tuxation.com/setuid-on-shell-scripts.html
    
    

  
  
  Just please keep in mind that those options are potential security threat.
  
  I hope this helps.
