Adding -E 1 to the check_by_ssh command will ignore the first line of output.

In my previous message page 1, I have put the command definition and there is already -E 1

The check_by_ssh

# 'ssh_disk' command definition
define command{
command_name ssh_disk
command_line /usr/local/nagios/libexec/check_by_ssh -i /home/nagios/.ssh/id_dsa -H '$HOSTADDRESS$' -E 1 -C "/usr/lib/nagios/plugins/check_disk -w $ARG1$ -c $ARG2$ -e -p '$ARG3$'"

It could also be the single quotes around the macros remove them and see if that works for you.

No, the same ..

Can you login to the Nagios server as the nagios user and run the command like in the previous post, filling in the IP Address and arguments and post the output here?

Could you please post your service definition for the one that's using this check_command and failing? The command definition looks good, as well as the fact it's working over the CLI.

define service {
host_name xxxxxxx,
service_description /
check_command ssh_disk!20%!10%!/
use generic-service
}

To rule out parsing and values getting lost in translation, could you create a new command definition and assign this to your service? This isn't ideal, but it will at least help us to see what's going on. Let us know what the status is for the check when it comes back.

Code: Select all

$USER1$/check_by_ssh -i /home/nagios/.ssh/id_dsa -H xxxxxx -E 1 -C "/usr/lib/nagios/plugins/check_disk -w 10 -c 20 -e -p /"

# 'ssh_disk' command definition
define command{
command_name ssh_disk_test
command_line $USER1$/check_by_ssh -i /home/nagios/.ssh/id_dsa -H '$HOSTADDRESS$' -E 1 -C "/usr/lib/nagios/plugins/check_disk -w 10 -c 20 -e -p /"
}



define service {
host_name xxxxxx, xxxxxxx
service_description /_test
check_command ssh_disk_test
use generic-service
}


It's the same ... check goes down when the session is closed

It really sounds like the storage isn't persistent if that's the case. What type of firewall device is this?
