[one-users] Problem with monitoring scripts

[Olivier Sallou]

Thanks, 
there was an existing dir "one-im" in /tmp. I deleted the existing dir and it worked. 
New dir has been created with correct files.

I installed open nebula 1,4. I have a front end and a worker node. 
I have an error message with "master cannot send script" to worker node: 

Mon Sep 27 17:06:17 2010 [InM][I]: Monitoring host genomobyle (0) 
Mon Sep 27 17:06:19 2010 [InM][E]: Error monitoring host 0 : MONITOR FAILURE 
0 Can not send script to remote machine: genomobyle 

As I had to customize user and scripts, I wonder WHERE the master try to 
send scripts. Master is Ubuntu based with system install while worker is a 
Red Hat system. 
I checked that ssh and scp for the oneadmin user can be done without 
password, this is ok. However I cannot find where the master tries to send 
the scripts (I configured one with the ssh transport). 

I cannot find in documentation the required directories on workder node. 

Copy and execute code for im probes in one 1.4 is located here: 

http://dev.opennebula.org/projects/opennebula/repository/revisions/one-1.4/entry/src/im_mad/im_ssh/one_im_ssh.rb#L60 

That ssh connection creates the remote directory and writes the script 
using "cat >" (script is sent in stdin). 

By default remote scripts directory is /tmp/one-im. Check that is dir 
and files do have correct permissions if it exists, or delete it, will 
be created when monitoring the host. 

Bye
