network, you compile normal data for your network. You can compare this normal data against the
results that you get when the network experiences trouble.
For example, ping each node to discover how long it typically takes to receive a response from
devices on your network. Capture and save each response time and you can use these baseline
response times to help you troubleshoot. You can also use the show tech and show khi
performance {buffer-pool|cpu|memory|process|pthread|slabinfo} commands to
obtain baseline output for normal system behavior.
