LoadRunner Controller throws up errors here and there almost all the time; 99% of these errors are due to either scripting problems or code changes (the other 0.9% are out of memory exception errors )
The errors generated in the Controller are usually enough to figure out what the problem is, however there are times where the errors generated leave one searching for clues like a scavenger hunt.
Then I came across this option in the Controller… “Generate snapshot on error“… hmm, this looks like it could prove very useful for web testing.
Indeed it did. Turns out that every-time an error is encountered in the Controller, a snap-shot of the page the error was encountered on will be saved and stored in the results folder in .html format.
LoadRunner is a suite of applications designed specifically for performance testing of computer systems.
Put at a very high level, LoadRunner is used to throw load (or Virtual Users in LoadRunner terms) at a system to check for performance counters such as throughput, CPU per transaction etc. LoadRunner supports a variety of different architectures including Web, ERP, CRM and more.
This article details the steps of how to set-up multiple load generators to work with your LoadRunner Controller environment.
There are several drivers for going with this approach:
- Your load generator may actually sit on the same box as your Controller (design flaw)
- Your load generator may be a low spec box which maxes out at X number of VUsers
- You want load to hit the target from multiple machines to introduce threading.
