mtools

mtools is a collection of helper scripts to parse and filter MongoDB log files (mongod, mongos), visualize log files and quickly set up complex MongoDB test environments on a local machine.

What's in the box?

The following tools are in the mtools collection:

mlogfilter
slices log files by time, merges log files, filters slow queries, finds table scans, shortens log lines, filters by other atributes

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

mplotqueries
visualize logfiles with different types of plots (requires matplotlib)

mlogvis
creates a self-contained html file that shows a visualization in a web browser (as an alternative to mplotqueries)

mlaunch
a script to quickly spin up local test environments, including replica sets and sharded systems (requires pymongo)
