Script for Exim-mail server

[kiko84]

Hi,

I'm searching for scripts and XML files to graph statistic of my Mail server - Exim. I have found a script on this forum but for Postfix and it doesn't work.

Somebody can help me ?

Thanks

Here is a quick script I threw together for such a purpose. It's quick, dirty, and worked for me. YMMV. If you improve upon it, please post the new code to this topic or e-mail me.

I changed the script a bit...I'm no perl programmer so feel free to point out any bad practices Anyway, it's working for me.
I'm also quite new to cacti so if there's a better way do this, point that out to

I run the above script from cron:

# SNMP Scripts

/usr/local/share/snmp/scripts/cron:

Code: Select all

#!/usr/local/bin/bash
#SNMP scripts
/usr/local/share/snmp/scripts/exim.cron.pl >/usr/local/share/snmp/scripts/exim.cron.log

I read the data from the output/ files with scripts and snmp.

snmpd.conf:

Code: Select all

#Custom OIDs
exec .1.3.6.1.4.1.3032.64 exim-traffic /usr/local/share/snmp/scripts/exim-traffic
exec .1.3.6.1.4.1.3032.65 exim-rejected /usr/local/share/snmp/scripts/exim-rejected
exec .1.3.6.1.4.1.3032.66 exim-delivery /usr/local/share/snmp/scripts/exim-delivery

exim-traffic script is simple:

Code: Select all

#!/usr/local/bin/bash
cat /usr/local/share/snmp/scripts/output/exim-traffic.output

the others look the same.

After you added the lines snmpd.conf do a kill -HUP snmpd-pid and:
run script: /usr/local/share/snmp/scripts/exim.cron.pl
try this: snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.3032
Should give you something like:

Nothing left but to get the data in to cacti:

i tried this, but i get:

also when doing an snmpwalk, i get the following:

I run the above script from cron:

Code: Select all

# SNMP Scripts
*/5 * * * * /usr/local/share/snmp/scripts/cron > /dev/null 2>&1

/usr/local/share/snmp/scripts/cron:

Code: Select all

#!/usr/local/bin/bash
#SNMP scripts
/usr/local/share/snmp/scripts/exim.cron.pl >/usr/local/share/snmp/scripts/exim.cron.log

I read the data from the output/ files with scripts and snmp.

snmpd.conf:

Code: Select all

#Custom OIDs
exec .1.3.6.1.4.1.3032.64 exim-traffic /usr/local/share/snmp/scripts/exim-traffic
exec .1.3.6.1.4.1.3032.65 exim-rejected /usr/local/share/snmp/scripts/exim-rejected
exec .1.3.6.1.4.1.3032.66 exim-delivery /usr/local/share/snmp/scripts/exim-delivery

exim-traffic script is simple:

Code: Select all

#!/usr/local/bin/bash
cat /usr/local/share/snmp/scripts/output/exim-traffic.output

the others look the same.

After you added the lines snmpd.conf do a kill -HUP snmpd-pid and:
run script: /usr/local/share/snmp/scripts/exim.cron.pl
try this: snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.3032
Should give you something like:

Code: Select all

SNMPv2-SMI::enterprises.3032.64.2.1 = STRING: "exim-traffic"

Nothing left but to get the data in to cacti:

exim-traffic:

Code: Select all

#!/usr/local/bin/bash
snmpdata=`snmpget -v 2c -c $1 $2 .1.3.6.1.4.1.3032.64.101.1 | awk -F""" '{ print $2 }'`
echo $snmpdata

Input parameters
$1 is communityname
$2 is hostname
