May be you can jump to the next lab and go back here in a few minutes as reports need some time to be populated
5. Launch the host report you created previously

20 of 26 © 2010 Cisco Systems, Inc. All rights reserved

6. Explore period, granularity, style

7. Launch the 3 response time reports you created together

21 of 26 © 2010 Cisco Systems, Inc. All rights reserved

8. Interpret the result

3. Create a new threshold

4. Choose “network layer host “, and In Packets

5. Put the ip address, choose an interval of 30 seconds, select delta as sample timer, put a rising threshold equal to the threshold traffic rate multiplied by the interval (10 pakets/sec * 30 sec), select your rising event
