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.

The following tools are in the mtools collection:
mlogfilter <https://rueckstiess.github.io/mtools/mlogfilter.html>__
slices log files by time, merges log files, filters slow queries, finds
table scans, shortens log lines, filters by other attributes, convert to
JSON
mloginfo <https://rueckstiess.github.io/mtools/mloginfo.html>__
returns info about log file, like start and end time, version, binary,
special sections like restarts, connections, distinct view
mplotqueries <https://rueckstiess.github.io/mtools/mplotqueries.html>__
visualize log files with different types of plots (requires matplotlib)
mlaunch <https://rueckstiess.github.io/mtools/mlaunch.html>__
a script to quickly spin up local test environments, including replica sets
and sharded systems (requires pymongo)
mtransfer <https://rueckstiess.github.io/mtools/mtransfer.html>__
an experimental script to transfer databases between MongoDB instances by
copying WiredTiger data files (requires pymongo and wiredtiger)
For more information, see the mtools documentation <https://rueckstiess.github.io/mtools>__.
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, 3.9, and 3.10.
Some of the tools have additional dependencies, which are listed under the
specific tool's section. See the installation instructions <https://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 October 2022, that includes MongoDB 4.2 or newer.
NOTE: logv2 format (MongoDB 4.4+) is not fully supported yet.
See Changes to mtools <https://rueckstiess.github.io/mtools/changelog.html>__
for a list of changes from previous versions of mtools.
