Monitoring

• simple monitoring tools do 95% of task

  • e.g. ftp://ndtl.harvard.edu/pub/SNMPoll
  • e.g. http://www.merit.edu/internet.tools/rover/

• monitor should be both poll & trap based for best reliability

  • but just polling will do better than just traps
  • and will work fine other than response latency

• simple, terse, messages on problems
