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:
slices log files by time, merges log files, filters slow queries, finds table scans, shortens log lines, filters by other atributes, convert to JSON
returns info about log file, like start and end time, version, binary, special sections like restarts, connections, distinct view
visualize logfiles with different types of plots (requires matplotlib)
creates a self-contained html file that shows an interactive visualization in a web browser (as an alternative to mplotqueries)
a script to quickly spin up local test environments, including replica sets and sharded systems (requires pymongo)
generates structured pseudo-random data based on a template for testing and reproduction
