RRDtool alternatives
RRDtool is a tool for creating data logging and graphing applications. It maintains a simple round-robin database to store its data. This makes it easy to add new data records to the log file, maintains the data in a compact form, and makes it possible to access the data in a very fast way. The system stores and displays time-series data (values that change over time, like connection bandwidth, CPU load, temperature, traffic, etc.). It stores the data in a very compact way that will not expand over time, and it can create graphs showing the data.
The data can be accessed in several ways: as simple time-series data over a period of time, in simple graphs showing the data at a particular time, or in more complicated graphs showing how the data varied over a period of time. This same approach can be used to store sensor readings from a weather station, transaction rates from a web server, or CPU load from a Unix machine.
