Java gateway not listening

15-12-2014, 11:04

Hi,

I want to use the java gateway to monitoring JMX stuff, but cant get the java-gateway daemon to listen on given port. I can start the java-gateway with

/etc/init.d/zabbix-java-gateway start

it will start and gives OK but crashes direct after startup instead of starting to listen on port 10052.

here's my zabbix_java config

Code:

# This is a configuration file for Zabbix Java Gateway.
# It is sourced by startup.sh and shutdown.sh scripts.

### Option: zabbix.listenIP
#       IP address to listen on.
#
# Mandatory: no
# Default:
LISTEN_IP="0.0.0.0"

### Option: zabbix.listenPort
#       Port to listen on.
#
# Mandatory: no
# Range: 1024-32767
# Default:
LISTEN_PORT=10052

### Option: zabbix.pidFile
#       Name of PID file.
#       If omitted, Zabbix Java Gateway is started as a console application.
#
# Mandatory: no
# Default:

PID_FILE="/var/run/zabbix/zabbix_java.pid"

### Option: zabbix.startPollers
#       Number of worker threads to start.
#
# Mandatory: no
# Range: 1-1000
# Default:
START_POLLERS=5

Java gateway not listening

Hey ZabbixITG,

Change your init script zabbix-java-gateway to init file script bellow:

cat /etc/init.d/zabbix_java
#!/bin/bash
NAME=zabbix-java
PATH=$PATH
DAEMON=/opt/zabbix/sbin/zabbix_java/startup.sh
DOWN=/opt/zabbix/sbin/zabbix_java/shutdown.sh
DESC="Zabbix Java Gateway daemon"
PID=/tmp/zabbix_java.pid
test -f $DAEMON || exit 0
set -e
case "$1" in
start)
echo "Starting $DESC"
$DAEMON
;;
stop)
echo "Stopping $DESC"
$DOWN
;;
*)
N=/etc/init.d/$NAME
# echo "Usage: $N {start|stop}" >&2
echo "Usage: $N {start|stop}" >&2
exit 1
;;
esac
exit 0

Regards,

Lagos

Same error

Hi lagos.mc,

I think I have the same problem, my Zabbix Java Gateway start ok but the port isn't listening.

I don't have Zabbix installed in /opt/zabbix. Where can I find the Java Gateway script?

Thanks
