The things that PCP brings to the table for monitoring cluster performance
- centralized monitoring and management of distributed processing
(PCP uses very efficient TCP/IP protocols to move the data about)
- a unified API to access _all_ performance data (from the h/w,
the o/s, the service layers and the applications) ... this
includes all of the metrics Joseph was asking about, and lots
more ... the same API works for different operating systems,
so monitoring tools are insulated from the details of dredging
interesting numbers from dark corners of each o/s
- the available performance data can be easily extended via a
a plugin architecture
- real-time and historical data sources are unified under the
- an inference engine for detecting common performance scenrios
and raising arbitrary alarms (can be used with both real-time and
historical data sources)
There is an open source stripchart monitoring tool developed by Michal
Kara (details from the News page off the oss.sgi.com projects page).
Other SGI-developed monitoring tools (including 3-D visualization of
performance) are not open sourced, but are are sold as part of the SGI
Linux solutions (ACE is one example)
We are always keen to communicate with people who'd be interested in
adapting or expanding PCP into new performance monitoring scenarios.
