Intermittent Server Failures Documented
An e-business website was experiencing intermittent,
apparently non-repeatable
failures which were having a negative influence on sales,
but the failures did not appear in any regular pattern.
The key idea in the eValid solution was
to construct a set of test scripts performing typical actions,
run them on 24 x 7 on a 10/hour basis,
and wait to generate enough instances of the "intermittent"
failures were documented in playback event logs
to permit changes to be made
to the server software.
After several weeks of regular monitoring,
detailed analysis of the captured failures led to
repairs of each problem,
and the observed failure rate dropped significantly.

Intermittent Server Failure Monitoring
description for full details.
