Aggregated data (reports and graphs) are stored for 180 days
Individual request logs are stored for 7 days
OpenTelemetry trace data can be sent to a customer-hosted Collector at no extra charge
Overhead
The minimum time charged for a test is 10 minutes
The set up time to launch load generators is not charged
Tests using less than 10 VU are charged as using 10
Every test is charged by its maximum target number of VU for the duration of the test
Compute capacity
Every 500 VUs in a test gets you one Locust worker (running on 1 vCPU with 2 GB RAM), plenty for most HTTP and WebSocket tests
If your users do very high throughput (more than 1,000 requests/s per worker), use other protocols that are heavier for the load generator, or need to do heavy calculations in your scripts you can increase the ratio—you are then charged for 500 VU per worker
