Web Resource Graphs in Load runner analysis

Retries per second:
  • No of attempted Server connections
  • A server connection is required-When an initial connection could not be made
  • When an initial connection is shutdown by Server
  • When an initial connection is unauthorized by Server
  • When a proxy authentication is required
  • When server could not resolve load genrator’s IP address
Connections per second:
  • Number of TCP/IP connections opened
  • Number of Connections Shutdown. No of connections is fraction of hits/sec
  • TCP/IP connections are expensive interms of server, router and network resource consumption. So HTTP request should use same connection instead of opening new connection each time of each request.
SSL connections per second:
  • No of SSL connections opened per second
  • After TCP/IP connection SSL connection is opened.
  • SSL connection has heavy resource consumption.
  • If we select simulate new user at each iteration then there should not be more than one SSL connection per sec
