Monitor mail server on Linux/Unix servers

[dstubbs]

I have been trying to configure Zabbix to monitor my mail server which is on a Fedora Core installation.

I have seen lots of posts from users with what they have tried but I cannot seem to get anything to work correctly.


Here is some of the things I have tried:

This always return 0-
UserParameter=mail.queue_count,mailq|grep "Total"|cut -f3 -d" "

The below commands should if they worked return the number of files in the mail queue times 2 which can be corrected by a .5 multiplier.

This always returns 0-
UserParameter=mail.queue_count,ls /var/spool/mqueue/ | wc -w

This one always returns 1-
UserParameter=mail.queue_count,echo /var/spool/mqueue/* | wc -w

The below command always returns 'Not Supported'-
UserParameter=mail.queue_size,ls -lA /var/spool/mqueue | grep "total" | cut -f2 -d" "

Now if I su to the zabbix user and run these commands at the console, I get the correct output. Note: I had to add the zabbix user to the mail in order to read the /var/spool/mqueue directory.

Has anyone had luck with trying to monitor their mail queue and size parameters?

Thanks

Well i was just looking into this subject but since I'm using postfix I'd use a command like this:

mailq |grep "Requests." | cut -d " " -f 5
which will give me the total entries in the queue.

mailq check that works with sudo (mailq privileged command)

--zabbix node--
1. add the user zabbix to sudo without password
2. copy zabbix_sendmail.pl script to zabbix executable directory
3. edit zabbix_agentd.conf file add:
#sendmail stats
UserParameter=sendmail.mailq,/usr/local/zabbix_agentd/zabbix_sendmail.pl
4. restart zabbix_agentd
--zabix node--

--zabbix server--
1. create item
key=sendmail.mailq
type of information=numeric
--zabbix server--

by using sudo with no password zabbix will now be able to execute the privileged mailq command and sendmail results

hope this helps
