Customer says they need 95th percentile response time value for all transactions. Your scenario has 10 virtual users which you know will generate at least 90 observations for each transaction. Your colleague says you must change your scenario to ensure 95th percentile can be calculated. You decide to:
For LoadRunner Agent to be running in process mode on a Windows machine, what must be true?
You have 10 observations for response times (all in seconds) - 1,2,3,4,5,6,7,8,9,10. The correct values for average and 90th percentile are:
Your test scenario has 200 vusers. Beyond 50 vusers, you notice that response times stayed the same but Total transactions per second and Throughput (bytes) went down. You decide to:
Your script has a LoadRunner parameter called ticket_amount. In order to print its value for debugging purpose the right code is:
A character array called username can be declared in C as follows:
Run-time settings in the Controller allow you to select either thread or process mode for running your test. You prefer:
You can create blocks in run-logic:
Receive Request Timeout value should be:
- Imagine a small store with a single clerk and an area for browsing products and no one leaves without buying something. A customer enters the store, browses available products, selects one of them, pays for it at the counter and then exits the store. Assume that this is a stable system (the arrival rate at which people enter the store is the same as their exit rate) and think time is defined as time spent by customers browsing the products before getting in line to pay for their selection.
If 30 customers were seen entering the store in a 60-minute interval and each customer spent 10 minutes in the store before leaving, what was the average number of customers in the store during this time?
Sequential data selection setting for a parameter should be used:
lr_param_sprintf can be used to create a new parameter from a string.
IP spoofing configuration
To prevent making requests during replay to hosts in a web HTTP/HTTP script that are of no interest to you (say external sites outside of your organization), you can:
Your customer has strict Response Time SLAs. You ran a test but forgot to add SLAs in the scenario before running it. You can:
A test scenario has 50 vusers. Think time is set to vary randomly between 50% to 150% of the recorded value. Pacing is set to 10 seconds. The test script has 5 transactions. The 95% response time SLA is 5 seconds. The test results indicate the SLAs were met. Customer asks if the system can support 50 simultaneous users in production. You say:
The vuser_init and vuser_end actions:
