Problem with check_by_ssh

[mirko stefanelli]

Hi,

yes if I doing it from the CLI as Nagios User is work fine.

Here:

Command definition:

# 'check_tablespace' command definition_
define command{
        command_name    check_tablespace
        command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -C
"/usr/local/nagios/libexec/check_tablespace $ARG1$ $ARG2$ $ARG3$ $ARG4$"


Host definition:

define host{
        use                     linux-server            ; Name of host
template to use
                                                        ; This host
definition will inherit all variables that are defined
                                                        ; in (or inherited
by) the linux-server host template definition.
        host_name               siper_afr
        alias                   siper_afr
        address                 10.5.3.xxx
        parents                 routerIperAfr
        }

service definition:

define service{
        use                             local-service         ; Name of
service template to use
        host_name                       siper_afr
        service_description             tablespace
        check_command
check_tablespace!siper!<user>!<passwd>!89
        notifications_enabled           0
        }

Service template definition:

# Local service definition template - This is NOT a real service, just a
template!

define service{
        name                            local-service           ; The name
of this service template
        use                             generic-service         ; Inherit
default values from the generic-service definition
        max_check_attempts              4                       ; Re-check
the service up to 4 times in order to determine its final (hard) state
        normal_check_interval           5                       ; Check the
service every 5 minutes under normal conditions
        retry_check_interval            1                       ; Re-check
the service every minute until a hard state can be determined
        register                        0                       ; DONT
REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!
        }

thank in advance,
Mirko.
