to monitor the remote linux machine i use check_by_ssh plugins . I loged in as nagios user and did key-gen and exchanged the plublic key so that nagios can do a password less login and get the datas like memory, cpu load etc.... But for some reason i dont see anything in the web interface except for (permission denied message). Later i tried doing the same as a root from the nagios server and it started showing up on the web interface. I want to achieve this with nagios user. Any help would be highly appreciated. -- Anirudh Srinivasan
