After running a scenario, you perform an analysis of the run by generating graphs
and reports.
If the graphs show a reasonable transaction time for the Vusers, you
do not need to further analyze the transactions. However, if the transaction
response time is not acceptable, you can use one of LoadRunner's monitoring tools
to pinpoint the problem. The monitoring tools are Transaction Breakdown, Network
Monitoring, and Resource Monitoring.
You use the Transaction Breakdown utility to determine where the bottleneck lies.
This utility indicates the cause of the slow response time: Network or client delays,
CPU performance, I/O delays, database locking, or other issues at the database
server. The transaction breakdown utility gives you detailed information about each
of the components by displaying the client/network and server components for
each of the transactions in the scenario.
Once you determine where the problem lies, you can upgrade or reconfigure your
system accordingly.
