Stripcharts

Goals

Stripcharts is a system for recording and displaying time-varying system load and performance information. The basic idea:

  • A set of scripts, run periodically using crontab, record performance metrics (CPU load, network connection rates, queue lengths, etc.) as time-stamped entries in log files.
  • A web interface lets you generate graphs of combinations of these quantities, over whatever time scale you want.

Looking at these graphs can be a major help in tracking down problems in complex server systems. Stripcharts is independent of BOINC, but it's especially helpful for diagnosing performance problems in BOINC servers.

Stripchart data

  • CPU load
  • number of users
  • number of results
  • number of results sent
  • number of results returned
  • disk usage
  • connections/second
  • network bandwidth
