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
