mentat.module.ideagen module

This Mentat module is a script providing functions for generating IDEA messages, mainly for testing or development purposes.

The messsages are generated using prepared templates filled with randomized values of certain keys.

Currently this script is work in progress and many features are hardcoded, like the lists of values for message randomization process.

This script is implemented using the pyzenkit.zenscript framework and so it provides all of its core features. See the documentation for more in-depth details.

Message templates

Message templates are based on jinja2 templates. The location of template directory can be adjusted with command line option --template-dir or configuration file directive template_dir and by default is set to /etc/mentat/templates/idea.

Usage examples

# Display help message and exit.
mentat-ideagen.py --help

# Run in debug mode (enable output of debugging information to terminal).
mentat-ideagen.py --debug

# Run with increased logging level.
mentat-ideagen.py --log-level debug

# Generate given number of messages.
mentat-ideagen.py --count 10

# Generate random number of messages up to given max count.
mentat-ideagen.py --random-count 10

# Generate messages into given queue directory.
mentat-ideagen.py --queue-dir /var/mentat/spool/mentat-inspector.py/incoming
