Lograptor is a GREP-like search tool for system logs written in legacy BSD syslog format RFC 3164 and for IETF syslog protocol RFC 5424.
The program can perform searches in syslog files like as the UNIX command "grep", but with the addition of some filters and parameters, useful to restrict the search field and retrieve the relevant information from log files. You could specify parameters like hostname, application, date, time range, plus a set of filters on message data.
Lograptor can also produce reports and publish them into a directory or send them by e-mail. The report may be a general or a specific report tailored for some accounts or hosts.
The basic idea is to have a compact and highly configurable CLI tool for system logs analysis. The log analysis is based on application or device that originated the message, using a set of rules for matching and for report composition.
The project uses parts of Epylog package under LGPL terms with author's permission.

Installing from package:
sudo pip install lograptor # System wide installation, require root access. pip install --user lograptor # Installation into the user space.
Installing from source:
git clone https://github.com/brunato/lograptor cd lograptor/ python setup.py install python setup.py install_data
To verify if the program is installed type lograptor without arguments on the command line. The default configuration location and settings will be shown.
After the installation copy the default configuration files of the package source into /etc/lograptor to define your custom configurations:
/etc/lograptor/lograptor.conf Default main configuration file /etc/lograptor/report_template.html Report HTML template /etc/lograptor/report_template.txt Report plain text template /etc/lograptor/conf.d/*.conf Configuration files for applications
For configuring the package at user level put your configuration in ~/.config/lograptor/lograptor.conf.
For more info about main configuration file please see "man lograptor.conf". For each application a configuration file is needed. Logs of unconfigured applications are simply ignored by the program. For more info please see "man lograptor-apps".
lograptor [options] PATTERN [FILE ...] lograptor [options] [-e PATTERN | -f PATTERNS_FILE ] [FILE ...]
Lograptor has many CLI options. Some options are identical to those of UNIX command "grep". If FILE arguments list is empty the program processes the log files of the last 24 hours. For more information on usage options see "lograptor --help" or "man lograptor".
