Optional components that pair with WPLoadTester. Same version as the main release.
Monitor CPU, memory, disk, network, and process metrics on your application servers during a load test. Correlate server load with client-side performance, side by side in the Analytics Dashboard.
Distribute load generation across multiple machines for tests larger than a single host can sustain. Install on each worker; the controller orchestrates the run and consolidates results.
