<html> <head> <style></style> </head> <body class='hmmessage'> Hello All, have been banging my head against the wall trying to get check_by_ssh to work. No matter what I try to do, I keep getting Remote command execution failed: . I have verified that I can ssh to the remote pc from the server as both root & the nagios user with no problem or password request so the key gen is fine. If I run check_ssh -H hostname, I gt back a response so I also know ssh is running ok on the target machine. Do not see any issues in the logs, as far as I can tell, it should be working fine. Am I missing something here? I have tried running the check_by_ssh plugin from the command line with no success , specifying ports, protocol, user, etc ./check_by_ssh -H pbylinux7 -C '/usr/local/nagios/libexec/check_ssh' -2 -4 -p 22 and have created the following check : services.cfg define service { use local-service ; check current load on machine hostgroup_name ssh-nagios-services service_description Current Load check_command check_ssh_load!5.0,4.0,3.0!10.0,6.0,4.0 } in command.cfg # 'check_ssh_load' command definition define command { command_name check_ssh_load command_line $USER1$/check_by_ssh -H $HOSTADDRESS$ -C "/usr/local/nagios/libexec/check_load -w $ARG1$ -c $ARG2$" } hostgroup has also been added <hr />The New Busy is not the too busy.
