## What it is
mtools is a Python collection of helper scripts for parsing, filtering, and visualizing MongoDB log files (mongod/mongos). It also includes mlaunch for spinning up local MongoDB test environments (replica sets, sharded clusters) and mtransfer for copying databases between instances.

## Use cases
- parse and filter mongodb log files
- visualize mongodb slow queries
- find table scans in mongod logs
- spin up a local mongodb replica set for testing
- set up a sharded mongodb cluster locally
- merge and slice mongodb logs by time
- get summary info from a mongodb log file
- transfer a database between mongodb instances

## When to choose
- you administer or debug MongoDB servers and need to analyze log files
- you need a quick local MongoDB test environment with replica sets or shards
- you want plots of query durations, connections, or restarts from logs

## When to avoid
- you use a database other than MongoDB
- you need production monitoring/alerting rather than ad-hoc log analysis
- you need a supported MongoDB Inc. tool for commercial support contexts
