Project Notes
mailgraph is a good tool at analysing mail server log, it supports many MTA(including sendmail, postfix, exim,etc.), with support for mailscanner,spamassassin,etc. As a whole, mailgraph can tell mail server statistics like how many messages sent/ received/ bounced/ rejected/ virus/ spam per time interval, which can be used as a sign of mail server healthy. This plugin includes a patch for mailgraph so that it will also output its statistics counter to an external file(plus the rra file),and a check_mailstat.pl which check the stat counter to see if it's ok, emit WARN/CRITICAl result if not.It can run on nagios server, or on remote server via NRPE.

NRPE: Unable to read output
by manh12a3, June 30, 2014
I download you plugin to test it but it didn't work for me and give me this error

Remote host:
I run command
./check_mailstat.pl -w 5:0:0:0:0:0 -c 10:0:0:0:0:0
OK: sent:0.03 received:0.03 bounced:0.00 rejected:0.00 virus:0.03 spam:0.00 |sent=0.03 received=0.03 bounced=0.00 rejected=0.00 virus=0.03 spam=0.00


/etc/init.d/nrpe.cfg
command[check_mailstat]=/usr/lib/nagios/plugins/check_mailstat.pl -w $ARG1$ -c $ARG2$

On server Nagios

./check_nrpe -H remotehost -c check_mailstat -a 50:0:0:0:0:0

NRPE: Unable to read output

Is there a way to run the script by check_ssh insted of NRPE?
by Diodati, December 31, 2013
I'd like to run the script on a remote server without NRPE support, but with ssh access. Is there a way to modify the script to accomplish that? Sorry, i'm not a perl programmer

Great plugin!
by Magalex_2x14, April 30, 2013
Thanks for the great plugin!
With Centreon 2.4.2 i can see graph only for "sent" counter. The problem is related to the performance data format. I'm not good specialist, but i took as a sample perfdata from other service with good graphs, and changed some code in check_mailstat.pl:

change line 97 to: my $perfdata = sprintf "'sent'=%-6.2f;;;;'received'=%-6.2f;;;;'bounced'=%-6.2f;;;;'rejected'=%-6.2f;;;;'virus'=%-6.2f;;;;'spam'=%-6.2f;;;;", @stat_counter;

add as line 98: $perfdata =~ s/s+//g; #remove spaces

I hope this helps... Sorry for bad English.

pnp4nagios template
by done, August 31, 2011
I made a pnp4nagios template which is similar with the one from mailgraph.cgi. Maybe you want to include it in the package. The data is displayed only in two graphs.

Owner's Reply:

There was in fact a PNP4Nagios template with check_mailstat.pl v0.9.1. However, I only updated it in my blog, and forgot to upload it here, sorry for that.
