samba monitor script

[p7]

hi all

someone braught down the main samba daemon by accident the other day, so we couldnt do processing. i tried to put a script in cron
to monitor samba n bring it up (which was supplied by itrc, thx. its a good script but i noticed that if i kill the main samba daemon and a client samba daemon is up, the script says samba is up. i then tried it straight from startsmb and it also thinks samba is up! it there a bug here?

thx in advance

There is a file which contains the PID of the main smbd daemon

/var/opt/samba/locks/smbd.pid

build a monitor script by the PID from this file and check if the daemon with this PID is running.

As a template take a look at

/opt/samba/HA/samba.mon

Your script is flawed in that if it sees any process with smbd, then it is okay.

As Rainer says, look for the actual pid:


#!/usr/bin/ksh

SMBD=`cat /var/opt/samba/locks/smbd.pid`
NMBD=`cat /var/opt/samba/locks/nmbd.pid`
set -o xtrace

if [ -z "`ps -ef |grep -v grep |grep $SMBD`" ] ;then
/sbin/init.d/samba stop
/sbin/init.d/samba start
elif [ -z "`ps -ef |grep -v grep |grep $NMBD`" ] ;then
/sbin/init.d/samba stop
/sbin/init.d/samba start
fi

If you are still interested -

HP CIFS Version A.02.02.01, released 3/27/2006, contains a new utility, smbmonitor. This is a perl script with many options to choose which daemons to monitor, restart them in necessary, collect data, send alert email, etc.

The Release Note at http://docs.hp.com/en/B8725-90102/index.html has a mention of the tool and the CIFS release can be download from the software depot at http://h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B8725AA
