<h3>Goals</h3>
|
|
|
|
|
<p>
|
|
|
|
|
Stripcharts is a system for recording and displaying
|
|
|
|
|
time-varying system load and performance information.
|
|
|
|
|
The basic idea:
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li> 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.
|
|
|
|
|
<li> A web interface lets you generate graphs of
|
|
|
|
|
combinations of these quantities,
|
|
|
|
|
over whatever time scale you want.
|
|
|
|
|
</ul>
|
|
|
|
|
Looking at these graphs can be a major help in tracking
|
|
|
|
|
down problems in complex server systems.
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
Stripcharts is independent of BOINC,
|
|
|
|
|
but it's especially helpful for diagnosing performance
|
|
|
|
|
problems in BOINC servers.
