I see that you are talking to a XenServer host. I am performing something similar. What I have had to do to achieve results is to create a local Nagios user on the XenServer host which has SSH keys to allow the server Nagios user to connect and avoid using any root SSH keys which the Nagios user is unlikely to be able to read.
Once you have connected to the XenServer host check that the Nagios user can execute the commands you are running. If you are simply looking at the dom0 as if it was a host and checking items such as cpu, memory or disk usage then you should not have a problem. If you are executing XenServer xe commands then you will need to pass a username and password that has access to the XenServer to run these commands. This will be root or another account that has been granted access. You can store these values in the resources.cfg file and pass them in your command definition. I have also noticed that your service definition is passing 4 arguments, where your command definition is only using 3 arguments and the hostaddress. It would be worth checking to make sure that you are passing the correct arguments from your service and command definitions to your remote host. James From: Eduardo Montes de Oca S.

In particular, there is one error: When I run a shell script located in another server, from the Nagios server using the check_by_ssh plugin, I don't have any errors and I can see the result of the script, like this: root@nagioserver#<mailto:root@TSM-SRV-V-114> /usr/lib/nagios/plugins/check_by_ssh -l root -H "ipxenserver" -C /usr/lib/nagios/plugins/check_Xencpu "OK:CPU%= 3" But, by any strange reason, when I configure the check for Nagios presents the results in its interface, I have the error: [cid:image001.png@01CD7B8F.4994F110] I have made the ssh authorization keys in both servers (Nagios and Xen), I configured the users, permissions,etc. And I can't to do this work it. Could someone help me solve this problem???? This is a part of my definition files: #XENServer define command { command_name check_by_ssh_xentop command_line /usr/lib/nagios/plugins/check_by_ssh -l '$ARG1$' -H '$HOSTADDRESS$' -C '$ARG2$' -i '$ARG3$' } #Hypervisor check define service{ use generic-service host_name ORLANDO service_description Hypervisor CPU check_command check_by_ssh_xentop!root!ipxenserver!/usr/lib/nagios/plugins/check_Xencpu.sh!/root/.ssh/id_rsa! } Regards! -- IC.
