Walkthrough on Postifx monitoring with Cacti

[nduda78]

Can someone post a step by step walk through on getting Postfix info (over SNMP perhaps?) to a cacti server and graph it. This should be for recieved, sent, bounced....etc

A search on the forums and google/news gives nothing on how to accompkish this in a step by step.

Thanks,
Nick

I could make templates but I don't know which OIDs should be used better. I made script that reports:
received
sent
clean
viruses
bounced
deffered
rejected
through SNMP. I don't know which would be the best place to mount this data in SNMP tree that does not conflict with other data.

Almost done, found some bugs, fixing and testing right away.

Fixed, tested, looks nice and right

Installation:
1) Configure SNMP agent on Mail server and make sure it is set up right.
2) Unzip fetch_mail_statistics.pl script in place of your choice. (I used /usr/local/bin)
3) Check that your perl path in script points to perl executable
4) Add following line in snmpd.conf file

When trying to import cacti_host_template_postfix_mailserver.xml I get the following error:

Dear typera

Can you create one item? DISCARD

Thank you so much.

I was able to get the template to import once I upgraded to the latest version of Cacti. I am now running into another issue. The postfix graphs do not seem to be updating properly. I get partial lines drawn for sent messages. Basically, the sent graph line will appear in segments across the graph. Anyone have any ideas as to why this is happening?

EDIT: Never mind it was because I had amavis changed to do everything local and the script filters out localhost.

I had everything up and working great...then I installed syslog-ng and only filtering shows up now. Anyone have any ideas? using postfix/amavis/clamd/spamassassin.
Here is the maillog portion of my syslog-ng.conf:

destination d_mail { file("/var/log/maillog" sync(10)); };
source s_local { internal(); file("/proc/kmsg" log_prefix("kernel: ")); unix-dgram("/dev/log"); };
filter f_filter4 { facility(mail); };
log { source(s_local); filter(f_filter4); destination(d_mail); };

I've gone though the steps as listed above, and have the following error when I manually run the poller.

Anyone have any ideas?

Did you configure SNMP agent on mailserver?
Does perl script have right permisions?

I am having problems displaying data in Cacti for Postfix Mailstats.

I am using the fetch_mail_statistics.pl script and grabbing the data via SNMP. I am using a loghost to log all my postfix mail data. I am running the fetch script on the loghost.

Here is the output of my logfile:

02/15/2006 01:20:05 PM - CMDPHP: Poller[0] Host[2] DS[41] SNMP: v1: loghost3, dsname: postfix_sent, oid: .1.3.6.1.4.1.2021.255.1, output: 84004
02/15/2006 01:20:05 PM - CMDPHP: Poller[0] Host[2] DS[40] SNMP: v1: loghost3, dsname: postfix_reject, oid: .1.3.6.1.4.1.2021.255.4, output: 0
02/15/2006 01:20:05 PM - CMDPHP: Poller[0] Host[2] DS[39] SNMP: v1: loghost3, dsname: postfix_recv, oid: .1.3.6.1.4.1.2021.255.0, output: 0
02/15/2006 01:20:05 PM - CMDPHP: Poller[0] Host[2] DS[38] SNMP: v1: loghost3, dsname: postfix_deferred, oid: .1.3.6.1.4.1.2021.255.2, output: 14062
02/15/2006 01:20:05 PM - CMDPHP: Poller[0] Host[2] DS[37] SNMP: v1: loghost3, dsname: postfix_bounced, oid: .1.3.6.1.4.1.2021.255.3, output: 4076




This data never makes it to my graph.

Any ideas??

Hello,
I tried to import template but I got the following error:

Error: XML: Hash version does not exist

I run Cacti 0.8.6c on Debian Sarge.
