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.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>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.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I have also noticed that your service definition is passing 4 arguments, where your command definition is only using 3 arguments and the hostaddress.
