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.
- CPU load
- number of users
- number of results
- number of results sent
- number of results returned
- disk usage
- network bandwidth
