Also, the –t 20 was added because I was getting 10-second timeout messages, and wanted to make sure that the code was responding to the right item placed in the checkcommands.cfg file – so I changed that to –t 20 as well.)<o:p></o:p> <o:p> </o:p> My checkcommands.cfg entry:<o:p></o:p> <o:p> </o:p> # 'check_ssh' command definition<o:p></o:p> define command{<o:p></o:p> command_name check_ssh<o:p></o:p> command_line $USER1$/check_ssh -4 -t 20 -H $HOSTADDRESS$<o:p></o:p> }<o:p></o:p> <o:p> </o:p> My services entry:<o:p></o:p> <o:p> </o:p> define service{<o:p></o:p> use generic-service ; Name of servic<o:p></o:p> host_name <machine names here><o:p></o:p> service_description SSHPING<o:p></o:p> is_volatile 0<o:p></o:p> check_period 24x7<o:p></o:p> max_check_attempts 4<o:p></o:p> normal_check_interval 5<o:p></o:p> retry_check_interval 1<o:p></o:p> contact_groups admins<o:p></o:p> notification_options w,u,c,r<o:p></o:p> notification_interval 960<o:p></o:p> notification_period 24x7<o:p></o:p> check_command check_ssh<o:p></o:p> }<o:p></o:p> <o:p> </o:p> It is right now running as a service, but it fails in exactly the same way as a host-check command.
