is an industry-standard open source software package for storing and displaying time-series data. It is used extensively by system administrators, network engineers, and other IT professionals for monitoring and troubleshooting applications, services, and the infrastructure.
is a data logging and graphing system. It allows users to store data in round-robin database (RRD) files, and then quickly generate graphs of that data. It is written in C, and is very fast and efficient.
RRDtool allows for efficient storage of time-series data with high resolution over long periods of time.
- Round-robin databases: RRDtool stores data in round-robin database (RRD) files which are efficient, compact, and easy to use.
- Data sources: RRDtool supports various data sources such as counter, gauge, absolute, derive, and more.
- Consolidation functions: RRDtool provides a set of consolidation functions such as AVERAGE, MIN, MAX, LAST, and TOTAL.
- Graphs: RRDtool can generate various types of graphs such as line, area, stack, and more.
- Alarms: RRDtool can be used to set alarms which can be triggered when certain conditions are met.
- Thresholds: RRDtool allows users to set thresholds on data sources which can be used to limit or flag values.
- Plugins: RRDtool provides a set of plugins which can be used to extend the functionality of the system.
- Time-series data: RRDtool can convert data into time-series data which can be used for further analysis.
- Scalability: RRDtool is highly scalable and can store large amounts of data efficiently.
- Extensibility: RRDtool can be extended using custom code, which allows for more flexibility.
- Open source: RRDtool is open source software, which means that it can be freely modified and redistributed.
