Help: use monit to monitor a process doesn't work

5883 · 05-20-2014, 05:30 PM

Hi, sometimes my dhclient process could die without clue, don't know where the log file is.

so i want to use monit to restart dhclient.
This is what i added to /etc/monit/monitrc.
For testing, i'm called echo initially, when eth0's pid file is gone.

check process dhclient with pidfile /var/run/sendsigs.omit.d/network-manager.dhclient-eth0.pid
start program = "/bin/echo dhclient died, do something ..."

but nothing happened after 2 mins (i set in monitrc to check it every 2 mins)

Any suggestions ?

Something like this?

Code:

#!/bin/bash

if pgrep dhcpcd > /dev/null ; or pidof dhcpcd
then
    exit 0
else
    do something 
    exit 1
fi
#EOF
