Im not so good with numbers and graphs turn me on
I also think graphing make it easier to visualize what actually happen
with your email system instead of
looking at bunch of text & numbers.
I am using following combination of following software to create my
- modified updatemailstats.pl ( available from
How I set it up :
- Nagios does monitoring and at the same time it collect performance
data. So basically it combine 2 jobs into one : monitoring & reporting.
- n2rrd convert the performance data and convert it to rrd which can be
used by cacti
- cacti provide web interface for graph management which allows you to
easily zoom in and out of the graph, go to specific dates etc ...
Graph sample :
SMTP connect vs Reject :
Rejected message at SMTP level :
Accepted Message :
Postfix Queue Level :
I have more graph but currently too lazy to upload. You can modify
updatemailstats.pl quite easily to suit sendmail.
Another useful reporting tool that I use is splunk ( splunk.com ) &
mailwatch for mailscanner ( http://mailwatch.sourceforge.net/doku.php ) .
The latest version of splunk allow you to search logs easily and you can
create graph with ease.
