QueueStats -- Graph Qmail Local and Remote queue sizes

andrew2

An important part of maintaining the health of a Qmail server is to keep an eye on the size of the local and remote queues.
Messages piling up in the queues are a sure sign that something is wrong. Having historical graphs of queue size can help
for capacity planning as well. With that in mind, I set out to create a way to graph the queue size in Qmail using Cacti.

This is the very first version of this so bug reports/fixes and feature requests are more than welcome.

I am having trouble getting the exec line in the Qmail server's Snmpd.conf to work. I am running ucd-snmpd on a Red Hat 7.3 system. Any suggestions? SNMP seems to be working correctly for everything else.

Just in case, did you make sure to restart snmpd after making changes to the config file?

If so, what happens if you use snmpwalk to poll that data?

snmpwalk -Oav -v2c -c communityname serverip .1.3.6.1.4.1.2021.51.101.1

(Obviously replacing communityname and serverip with your SNMP community name and the IP of your qmail server.)

Also be sure that whatever user snmpd runs as has execute permission on queuesize.pl.

Try:

snmpwalk -Oav -v2c -c communityname serverip .1.3.6.1.4.1.2021.51.101.1

(Provided that's what you've entered into your snmp configuration on the target server.)

Looks like I had a typo in the README file...here is the updated package with the correct README.

thanks for this script!
works fine for me.

Just a hint:
the snmp community name is harcoded in the file queuecheck.pl and also not standard "public"

after changing this the script works fine for server localhost.

Hello guys,
I am getting some weird error when I run this:
snmpwalk -Oav -v2c -c commstring serverIP .1.3.6.1.4.1.2021.51.101.1
this is the error:
No more variables left in this MIB View (It is past the end of the MIB tree)

Please help

Hi All,

This script seems perfect for what I need, I have had to make a few modifications to queuesize.pl to get the correct output from the queue.

When I run it from the command line I get ;

$ /usr/bin/perl /usr/local/bin/queuesize.pl
Remote:25 Local:0

However, when I snmpwalk , I get the following ;

$ snmpwalk -Oav -v2c -c XXXX XXX.XX.XXX.XXX .1.3.6.1.4.1.2021.51
INTEGER: 1
STRING: "/usr/bin/perl"
STRING: "/usr/local/bin/queuesize.pl"
INTEGER: 0
STRING: "Remote:0 Local:0"
INTEGER: 0
""

As you can see the values are different?

Is this script still being worked on, or is there an alternative I should be using?

Thanks, Gavin
