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:
- mlogfilter * slices log files by time, merges log files, filters slow queries, finds table scans, shortens log lines, filters by other atributes, 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 logfiles with different types of plots;
- 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 quickly spin up local test environments, including replica sets and sharded systems;
- mgenerate * generates structured pseudo-random data based on a template for testing and reproduction.
