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.

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 attributes, convert to JSON

mloginfo

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

mplotqueries

visualize log files with different types of plots (requires matplotlib)

mlogvis

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

mlaunch

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

mtransfer

an experimental script to transfer WiredTiger databases between MongoDB instances by copying data files (requires pymongo and wiredtiger)
