These are tools to analyze SpamAssassin logs and generate reports. Generally, they take syslog data logged by the 'spamd' server as input.

- mailgraph: Generates graphs from syslogs. demo available.
- mailscanner-mrtg – demo available
- mailwatch – no demo, but the previous link has screenshots
- monkeynoodle.org spamassassin MRTG scripts: Scans the maillog/syslog and feeds the SA results into a format from which MRTG is used to create graphs. demo available
- sa-stats for 3.3 Not updated since 3.0 (or earlier) This works OK for 3.2.5, but you might benefit by changing the default log file location, and start time (try "yesterday"). --top=10 seems to produce unlimited output. The script doesn't seem to analyse usefulness of particular rules, but the performance figures might be helpful.
- munin: Munin is a tool for graphing all sorts of information about one or more servers and displaying it in a web interface. It uses the excellent RRDTool (written by Tobi Oetiker) and is written in Perl. demo available
- PostConf – Postfix and SA management and content analysis (free and commercial)
- Perl Monk's rewrite of Mike's Stat Script
- qmailmrtg – example available
- sa-stats.pl (Dallas Engelken's version) : Generates a report in text or HTML from a spamd log file or from syslog. not to be confused with the "sa-stats.pl" in the SpamAssassin distribution; it's entirely different. Rules Emporium is no longer available. There's a copy of version 0.93 available here
- sa-exim-stats : Generates rrdtool graphs from sa-exim log files.
- spamdstats: Continuously parses spamd's log file in the background and stores various data in one Berkely DB file to be read by a second script.
- vispan – demo available
- sa-daily-report: Generates and mails a report of all the email quarantined as spam the previous day, to allow checking for false positives.
- spamness: An extension for Mozilla Thunderbird that gives visual feedback on each message's SpamAssassin score and offers links back to the rules database section of this wiki.
