Performance Counters for LoadRunner

Client-Side Counters

  • Response Time: Measures the time from when a user enters a request until the first character of the response is received.
  • Throughput: Represents the rate at which a computer or network receives requests per second.
  • Amount of Connection Pooling: Indicates the number of user requests that are met by pooled connections.
  • Maximum Active Sessions: Reflects the maximum number of sessions that can be active at once.
  • Hits per Second: Represents the number of hits on a web server during each second of a load test.

Server-Side Counters

  • Processor Usage: Measures the amount of time the processor spends executing non-idle threads.
  • Memory Use: Indicates the amount of physical memory available to processes on a computer.
  • Disk Time: Measures the amount of time the disk is busy executing read or write requests.

NO..All are not Server side metrices..Few among them like Memory, COU Utlisations , Disk time are server side metrices
