Email Statistics
Email Statistics
How to get statistics about the performance of your mail server
Built-In Statistical Reports
Server-Manager
Some email statistics can be seen from server-manager under "Administration", "Mail log file analysis"
qplogsumm.pl
SME 7.2 and later include the 'logterse' plugin to qpsmtpd as well as the 'qplogsumm.pl' statistics script. 'qplogsumm.pl' creates and updates /var/log/qpsmtpd/state which shows per-plugin statistics for any qpsmtpd plugin that appears in a qpsmtpd logterse entry.
Contribs & Addons
Brian Read's spamfilter-stats-7.pl
Brian Read's mailstats.pl script analyzes your qpsmtpd log files and sends a daily email to "admin" summarizing that day's email activity.
Download & Installation
wget -O /etc/cron.d/mailstats.cron \ http://mirror.contribs.org/smeserver/contribs/bread/mailstats/mailstats.cron wget -O /usr/bin/spamfilter-stats-7.pl \ http://mirror.contribs.org/smeserver/contribs/bread/mailstats/spamfilter-stats-7.pl
WARNING: Make sure that these files are accessible before executing the above commands! If you are unable to access http://mirror.contribs.org/smeserver/contribs/bread/mailstats/ the above commands will create empty files, overwriting existing versions.
Change Email Recipient
The email recipient is specified in the spamfilter-stats-7.pl file, currently (v0.6.11) at line 108, using:
$opt{'mail'} = "admin";
which will deliver email to the local 'admin' account on your SME server. Configure email forwarding in server-manager::Collaboration::Users::admin to deliver the emails to another location.
Handling @*.u Logfiles
Multilog occasionally generates log files that end in ".u" instead of ".s". The multilog manual says this:
- .s: This file is completely processed and safely written to disk.
- .u: This file was being created at the moment of an outage. It may have been truncated. It has not been processed.
While these files should not be generated under normal circumstances, they are (as attested by personal experience, forum posts and bug reports). In order to include these files when reporting email statistics, you will need to modify /etc/cron.d/mailstats.cron by changing
0 0 * * * root perl /usr/bin/spamfilter-stats-7.pl /var/log/qpsmtpd/*.s /var/log/qpsmtpd/current
to
0 0 * * * root perl /usr/bin/spamfilter-stats-7.pl /var/log/qpsmtpd/*.[us] /var/log/qpsmtpd/current
or
0 0 * * * root perl /usr/bin/spamfilter-stats-7.pl /var/log/qpsmtpd/@* /var/log/qpsmtpd/current
qplogtail
qplogtail is a script intended to help monitor /var/log/qpsmtpd/current and extract a concise but meaningful display of what the server is doing the the current moment.
qplogtail extracts 5 kinds of information:
- Normal connections:
28545 Accepted connection 4/30 from 86.139.2.73 ... - Errors in violation of Instances:
