Network Monitoring
Bryan Hess, head of networking in the computer center, explained how they monitor hundreds of networking switches at the lab, see his slides for many details.
- All monitoring done in-band.
- Extensive checking and archiving of results for later analysis.
- Monitor latency, packet loss, throughput as early warning of future switch failure.
- Network configurations stored in svn.
- They do NOT monitor "edge" devices (e.g. computers, about 5000 total), just the networking infrastructure.
- They also do not monitor end-user applications.
