LoadView uses Load Injector Servers from Amazon Web Services and Azure Cloud Services.  Load Injector Servers can be generated from a number of geographical zones. LoadView can instantiate up to 500 Load Injectors per zone. The number of LI Servers and the number of virtual users on each LI Server will be calculated automatically based on the LoadView scenario, the number of zones, and the calibration results if used.

By default, LoadView automatically selects geographical zones to ensure high performance and load balancing among LI Servers. However, while testing, you can adjust the distribution of the LI Servers and virtual users between different zones.

Custom Geo Distribution option is not supported during the free trial.

To customize LI geo-distribution, on the Test Scenario page turn off the Auto Distribution option and configure zones and virtual user allocation:

  1. In the Load Injector Geo Distribution section, click Change and disable Auto Distribution in the Geo Zones window.
  2. Select zones you need to use and apply changes.
  3. If necessary, adjust the allocation of virtual users among zones using the sliders in zone rows. To fix the virtual user allocation for the particular zone, click the lock button in the zone line.

For example, if the bulk of your visitors come from a particular region, you can set a higher percentage of the load to simulate from this zone.

Running Large Load Tests

For safety reasons, we limit the number of LIs to run a test. If you are planning to run very large load tests, please contact technical support to allocate extra capacity in AWS data centers.

Reference Load Injector Servers

LoadView runs a separate Reference Load Injector per each zone to measure reference test results for device state verification while testing. See more tips on Reference LIs usage in Advanced Usage of Reference Load Injectors.

Auto Distribution Mode

When Auto Distribution is on, Reference Load Injector is not used.

Custom LI Servers Distribution

By default, when you turn off the Auto Distribution option and set up custom geo zones, LoadView runs a Reference Load Injector in the first selected zone. You can manually disable/enable a Reference Load Injector for each zone in the Load Injector Geo Distribution section.

Note that Reference Load Injectors are billed according to the common LI pricing
