would like a broadcast message when pid changes..

[Tom H]

Hi,

I am using monit on CentOs 6.2 instances, but I cannot get it to 
broadcast a message when a service is restarted.

Any suggestions on what am I doing wrong here...


address@hidden ~]# cat /etc/monit.d/munin-node.conf
check process munin-node with pidfile /var/run/munin/munin-node.pid
start program = "/etc/init.d/munin-node start"
stop program = "/etc/init.d/munin-node stop"
if changed pid then exec "/bin/echo logger | /usr/bin/wall"


address@hidden ~]# cat /etc/monit.conf
set daemon 20 # check services at 2-minute intervals
set httpd port 2812 and
use address localhost # only accept connection from localhost
allow localhost # allow localhost to connect to the server and
include /etc/monit.d/*



address@hidden ~]# ps -ef | grep munin; service munin-node restart; 
ps -ef | grep munin-node
