Monitor SpamAssassin with MRTG

If you want to monitor how many e-mails are tagged SPAM you can use MRTG (which I love). First install MRTG as mentioned in the guide. You need to place two statistics gathering "programs" in your /etc/mrtg directory. An example of SpamAssassin MRTG statistics can be seen here.

[root@e-smith]# cd /etc/mrtg
[root@e-smith]# chmod 755 spamstats.pl
[root@e-smith]# chmod 755 spam-stats


if you want to use my spamassassin MRTG config file then also download that


You now need to create the output directory where MRTG will place result data. This directory is configured in the spamassassin.cfg file and in my case /home/e-smith/files/ibays/mrtg

[root@e-smith]# mkdir /home/e-smith/files/ibays/mrtg/html/spamassassin

You should now be able to run MRTG (notice that you get warnings in the first two runs)

[root@e-smith]# mrtg spamassassin.cfg

You would properly like to have this added to your existing MRTG cron job so add a line in the all-ip file (also located in /etc/mrtg)
[root@e-smith ]# pico all-ip
Insert the following line in the bottom and press CTRL-X, Y, to save:
/usr/bin/mrtg /etc/mrtg/spamassassin.cfg;
If you want to verify that you get data from your log files you can run both programs (spam-stats and spamstats.pl) from the command line.
ex.
[root@e-smith ]# ./spam-stats
spam: 4
clean: 19
skipped: 0
total: 23
processed: 23
[root@e-smith ]# perl spamstats.pl localhost spam
4
23
