Check_jmx plugin problem

[Emmanuel Chanteloup]

Hi Natxo,

First, thank you for your time.

Here is my nrpe.conf :
_________________________________________________________________________________________________

log_facility=daemon

pid_file=/var/run/nrpe.pid

server_port=5666

nrpe_user=nagios

nrpe_group=nagios

dont_blame_nrpe=0


debug=1

command_timeout=60

connection_timeout=300

command[check_users]=/usr/local/nagios/libexec/check_users -w 10 -c 15
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c
30,25,20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p
/dev/mapper/VolGroup00-LogVol00
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10
-s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 655 -c
700
command[check_jmx]=/usr/local/nagios/libexec/check_jmx -U
service:jmx:rmi:///jndi/rmi://localhost:8999/jmxrmi -O java.lang:type=Memory
-A HeapMemoryUsage -K used -I HeapMemoryUsage -J used -vvvv -w 800000000 -c
1500000000

_________________________________________________________________________________________________

all my commands are working except the check_jmx. Nrpe is running through
xinetd, here is my nrpe file in /etc/xinetd.d :

service nrpe
{
        flags           = REUSE
        socket_type     = stream
        port            = 5666
        wait            = no
        user            = nagios
        group           = nagios
        server          = /usr/local/nagios/bin/nrpe
        server_args     = -c /usr/local/nagios/etc/nrpe.cfg --inetd
        log_on_failure  += USERID
        disable         = no
        only_from       =  10.1.2.1 127.0.0.1 10.1.2.200
}

Regards,

emmanuel
