**mtools** is a collection of helper scripts to parse, filter, and visualize
MongoDB log files (``mongod``, ``mongos``). mtools also includes ``mlaunch``, a
utility to quickly set up complex MongoDB test environments on a local machine,
and ``mtransfer``, a tool for transferring databases between MongoDB instances.

   JSON

   returns info about log file, like start and end time, version, binary,
   special sections like restarts, connections, distinct view

`mplotqueries <http://rueckstiess.github.io/mtools/mplotqueries.html>`__
   visualize log files with different types of plots (requires ``matplotlib``)

`mlaunch <http://rueckstiess.github.io/mtools/mlaunch.html>`__
   a script to quickly spin up local test environments, including replica sets
   and sharded systems (requires ``pymongo``)

`mtransfer <http://rueckstiess.github.io/mtools/mtransfer.html>`__
   an experimental script to transfer databases between MongoDB instances by
   copying WiredTiger data files (requires ``pymongo`` and ``wiredtiger``)

Requirements and Installation Instructions
------------------------------------------

The mtools collection is written in Python, and most of the tools only use the
standard packages shipped with Python. The tools are currently tested with
Python 3.7, 3.8, and 3.9.

Some of the tools have additional dependencies, which are listed under the
specific tool's section. See the `installation instructions
<http://rueckstiess.github.io/mtools/install.html>`__ for more information.

The mtools suite is only tested with actively supported (non End-of-Life)
versions of the MongoDB server. As of December 2021, that includes
MongoDB 4.0 or newer.
