Health monitor to check File on server

Hi,

 

 

There is a bug for default smb monitor in version 10.2.0

 

 

You must create a script in /usr/bin/monitors/SMB_Monitor_custom with the rights 755

 

 

And then add in local traffic/monitors menu an external script with the arguments "login" "password" "path"

 

 

 

http://devcentral.f5.com/wiki/default.aspx/AdvDesignConfig/Windows_File_Share_Monitor_SMB_CIFS.html

 

 

or this script

 

 

!/bin/bash

 

 

Save as /usr/bin/monitors/SMB_monitor_custom.bash

 

Make executable using chmod 755 /usr/bin/monitors/SMB_monitor_custom.bash

 

 

Use a custom shell command to perform a health check of the pool member IP address and port

 

 

Log debug to local0.debug (/var/log/ltm)?

 

Check if a variable named DEBUG exists from the monitor definition

 

This can be set using a monitor variable DEBUG=0 or 1

 

 

These arguments are supplied for all calls to that monitor

 

command : smbget -u login -p pass -w domain smb://server/path_to_file

 

$1 = IP_V6

 

$2 = port

 

$3 = login

 

$4 = pass

 

$5 = domain

 

$6 = complete path to the (empty) file to check

 

 

if [ -n "$DEBUG" ]

 

then

 

if [ $DEBUG -eq 1 ]; then logger -p local0.debug "EAV `basename $0`: \$DEBUG: $DEBUG"; fi

 

else

 

If the monitor config didn't specify debug, enable/disable it here

 

DEBUG=0

 

logger -p local0.debug "EAV `basename $0`: \$DEBUG: $DEBUG"

 

fi

 

 

Remove IPv6/IPv4 compatibility prefix (LTM passes addresses in IPv6 format)

 

IP=`echo $1 | sed 's/::ffff://'`

 

 

Save the port for use in the shell command

 

PORT=$2

 

 

Check if there is a prior instance of the monitor running

 

pidfile="/var/run/`basename $0`.$IP.$PORT.pid"

 

if [ -f $pidfile ]

 

then

 

kill -9 `cat $pidfile` > /dev/null 2>&1

 

logger -p local0.error "EAV `basename $0`: exceeded monitor interval, needed to kill ${IP}:${PORT} with PID `cat $pidfile`"

 

fi

 

 

Add the current PID to the pidfile

 

echo "$$" > $pidfile

 

 

Debug

 

if [ $DEBUG -eq 1 ]

 

then

 

Customize the log statement here if you want to log the command run

 

logger -p local0.debug "EAV `basename $0`: Running for ${IP}:${PORT} using smbget -u "$3" -p "$4" -w "$5" -O -q smb://${IP}/$6"

 

fi

 

 

Send the request request and check the response

 

smbget -u "$3" -p "$4" -w "$5" -O -q smb://${IP}/$6 >/dev/null 2>&1

 

 

Check if the command ran successfully

 

Note that any standard output will result in the script execution being stopped

 

So do any cleanup before echoing to STDOUT

 

if [ $? -eq 1 ]

 

then

 

if [ $DEBUG -eq 1 ]; then logger -p local0.debug "EAV `basename $0`: Succeeded for ${IP}:${PORT}"; fi

 

echo "UP"

 

else

 

if [ $DEBUG -eq 1 ]; then logger -p local0.debug "EAV `basename $0`: Failed for ${IP}:${PORT}"; fi

 

fi

 

 

rm -f $pidfile

 

 

 

Thx Hoolio for ur help
