collectl

Utility to collect Linux performance data

Collectl is a performance monitoring and benchmark tool that tries to do it all. You can choose to monitor any of a broad set of subsystems which currently include buddyinfo, cpu, disk, inodes, infiniband, lustre, memory, network, nfs, processes, quadrics, slabs, sockets and tcp. Output can also be saved in a rolling set of logs for later playback or displayed interactively in a variety of formats. If all that isn't enough there are additional mechanisms for supplying data to external tools by generating output as s-expressions, a format of choice for some tools such as supermon or in another format called list-expressions. This output can be written to a file or sent over a socket. You can even create files in space-separated format for plotting with external packages like gnuplot.
