Return code 255 and flapping services on Solaris9

[Peter Michael Calum]

Hi

I dont think the debug.sh script works with check_by_ssh, it seems that
the parameters is misunderstood in some way

the command in my services.cfg looks like this :
------------------------------------------------
define service{
        use                             local-service         ; Name of
service template to use
        hostgroup_name                  SUN240, SUN440, SUN480, RHEL,
TSP4
        host_name                       khk23dsg6.ip.tdk.dk
        service_description             DISK
        check_command                   check_by_ssh! -l nagios -i
/home/nagios/.ssh/id_rsa -C 'plugin/check_disk -w 25% -c 15% -l -X
devfs'
        notifications_enabled           1
        }

I think maybe the 'plugin/check_disk -w 25% -c 15% -l -X devfs' gives
the problem 
(on the host called by check_by_ssh the plugins is in 'plugin/' under
the nagios user account)

disapeared)

To debug, you need to wrap your plugin call. See this fine article:
