Cisco Prime NAM for Application Performance Troubleshooting

Intelligent Application Performance Analysis Cisco Prime™ NAM Applications Server Client Client Delay Server Network Client Client Network Delay Server Network Delay Application Delay Network Delay Client Total Delay Identify sites, hosts, and applications with poor performance Isolate the problem to the network, server, or application Trigger packet captures based on response-time alarms Validate quality-of-service (QoS) planning assumptions Analyze application behavior and trends for capacity planning

Adobe Flash Demonstration Outline (1 of 3) Identify site and application with response-time degradation Choose Monitor > Alarm Summary Select Data Center in Top N Sites by Alarm Count and right-click Alarm Details. Choose Monitor > Response Time Summary Choose Filter: Site - Data Center Select http in Top N Applications by Server Response Time and right-click Analyze Application Response Time. Review baseline and determine whether degradation is due to network or server Choose Filter: Time – 1 Day and zoom into last spike in transaction time. Scroll down. Choose Other Metric: Metric 1 - Avg Round Trip Time, and Metric 2 - Number of Transactions. Select Top Server in Top N Servers by Avg Server Response Time and right-click Analyze Host Traffic. Click Host Conversations
