There is not that many Perl tools for log analysis (monitoring, colorizing, etc) and management. Logwatch is probably the most well know Perl log analyzer. This type of tools is covered in log monitoring page.

Perl-based log analyzer essentially represent a primitive monitoring system and are flexible enough to be used as monitoring sensors for all popular monitoring solutions. They are usually pretty extensible and can be tuned to the task in hand, the operation which is much more difficult for analyzers written in other scripting languages as system administrators usually know Perl, not rarely other scripting languages.
One type of systems that you probably should avoid are those which just expose regular expressions via Perl, providing just a capability to apply regular expression to the stream of log records (log analyzers for dummies; of log stream grep tools). Such solutions essentially hide the Perl strengths downgrading it to the version of grep and as such are not attractive to competent system administrator. They bring very little to the plate.

Kazimir is a log analyzer. It has a complete configuration file used to describe what kind of logs (or non-regression test) to be watched or spawned and the kind of regexp to be found in them. Interesting information found in logs may be associated with "events" in a boolean and chronological way. The occurrence of events may be associated with the execution of commands.Release focus: Initial freshmeat announcement
Octopussy is a solution to manage your logs (also frequently called a SIM/SEM/SIEM Solution). Basically, it stores your logs, produces reports, and raises alerts.Release focus: Major bugfixes
Changes:
Reports in XML have been added. Logs Wizard allows you to check whether unknown logs match a Service that doesn't belong to the current Device. There is a global bugfix regarding special characters. There are bugfixes for Report Scheduler and octo_logrotate.
About:
devialog is a behavior/anomaly/signature-based syslog intrusion detection system which can detect new, unknown attacks. It fits comfortably in a heterogeneous Unix/Linux/*BSD environment at the core of a central syslog server. devialog generates its own signatures and acts upon anomalies as configured by the system administrator. In addition, devialog can function as a traditional syslog parsing utility in which known signatures trigger actions.Release focus: Minor bugfixes
Changes:
Bug fixes include better handling of lines with some special characters. A timing error was fixed within alert generation: sometimes alerts would be sent inadvertently based on the timing of a new log arriving as an alert was sent out in specific high-volume log situations. Altered signature generation creates more exact regular expressions.
LMF (Log Monitoring Framework) is a flexible log monitoring framework that allows the user to match text from log files using Perl regular expressions and capturing parentheses. An optional external command will be executed when a user-specified number of matches is found within a user-specified period. In additon to the trigger, the rule can also have a message associated with it; when the rule is triggered, that message will be logged to the LMF log file. Each rule can also have a duration associated with it; after a rule has been triggered and the duration has expired, an optional external command will be run.
Octopussy is a Perl/XML log analyzer, alerter, and reporter.
A small agent whose job is to monitor files on the system and send them via syslog protocol to a server
The Syslog Management Tool (SMT) is a Web-based system that collects syslog messages using a modified version of Modular Syslog. It processes them for errors and generate alerts, launches programs, or sends emails based on user-defined actions. Since it uses a Web console, rules, hosts, and much more can be centrally managed. It is designed to be disaster resilient by distributing components throughout a global enterprise to survive Web console loss, database loss, or syslog server loss.

This new design of syslog allows for an easy implementation of input and output modules. The modules that mantain compatibility with its precursor are included in the standard distribution along with four modules: om_peo (an implementation of PEO-1 and L-PEO, two algorithmic protocols for integrity checking), om_mysql and om_pgsql (modules that sends output to a MySQL and PostgreSQL database, respectively) and om_regex (a module that allows output redirection using regular expressions).Audit is a client/server tool that allows remote system logs auditing and centralizing. The server (auditd) runs, commonly, on audited (vulnerable) machines and the client (audit) on the auditors workstations. Multiple auditors are supported and managed by one or more auditors 'chiefs'; each auditor can be configured in a way allowing them to examine specific sets of logs and certify that possible intruders did not modify them.
Its modular design allows custom made authentication methods; other log sources and formats can be easily supported. All data transfers between both parties are encrypted.
When combined with Modular Syslog, audit makes the perfect auditing tool for system logs.

Epylog is a log notifier and parser that periodically tails system logs on Unix systems, parses the output in order to present it in an easily readable format (parsing modules currently exist only for Linux), and mails the final report to the administrator. It can run daily or hourly. Epylog is written specifically for large clusters where many systems log to a single loghost using syslog or syslog-ng.
