## What it is
RRDtool is the industry-standard open-source tool for storing time-series data in fixed-size round-robin databases and generating graphs from it. It ships as a C library (librrd), CLI tools, a caching daemon, and bindings for Perl, Python, Ruby, Lua, and Tcl.

## Use cases
- store time-series metrics in a fixed-size database
- graph router traffic and system metrics over time
- log sensor data like office temperature
- generate monitoring graphs from collected data sources
- export time-series data as XML
- integrate metrics logging into shell scripts or Python

## When to choose
- you need compact, fixed-size storage for metrics that never grows unbounded
- you want fast graph generation for monitoring dashboards
- you're collecting periodic samples from devices, sensors, or network interfaces
- you need a battle-tested, lightweight C library embeddable in other tools

## When to avoid
- you need full historical retention of every raw data point
- you want a modern query language or horizontal scaling like Prometheus or InfluxDB
- your data is irregular or event-based rather than periodic samples
- you need a REST API or cloud-native deployment
