Hi there, I've found some time to take a look at Gatling again and am working through getting started. I first ran the provided BasicExampleSimulation and I have some questions about the reports. 1) What is the difference between "Global - Requests /sec" and "Global - Transactions/sec".     For the basic example the charts are subtly different, but I'm not sure how and the wiki doesn't seem to mention transactions/sec 2) For the 'Latency' report under the details tab, the latency is always being reported as 0ms. Huh? How is that possible? Could it be a bug? 3) It would be great to have the details under 'Statistics' available at the 'Global' level. (ie aggregated over all request types). Is this possible? Thanks for any help. We are excited about maybe using Gatling - it looks like a great tool šŸ™‚ ---

ā€œTransactions/secā€ is the number of response received per sec. I can show you some kinds of bottlenecks on your app. > Iā€™ll fix the wiki today: > [https://github.com/excilys/gatling/issues/500](https://github.com/excilys/gatling/issues/500) Hi Stephane, Could you please clear this up a bit more: 1. Could you please explain failed / successfull requests and failed / successfull transactions? For the transaction(response) I assume the successful may be 200 and for failed - 404 response but what about requests? 2. What is ā€œAll sessionsā€ stand for? Suppose we have a test in which every user does a scenario that consists of three requests. Those are made subsequently with a random pause within one second. So in any particular second of the simulation what would the ā€œAll sessionā€ parameter present? Thanks! Regards, Eugene ---

Hi, > 1. Could you please explain failed / successfull requests and failed / > successfull transactions? For the transaction(response) I assume the > successful may be 200 and for failed - 404 response but what about requests? Request vs response charts are about counting the number of requests sent per second, or the number of responses received per second. Status is the one of the (request/response) pair, so it's the same for both. Failure is not only about response status code, for example:    - what if connection couldn't be established? The request couldn't even    be sent and that's a failure.    - if you set up a check on the body because you expect some content and    it's not here? Check failures are accounted too.    - what if you do expect another status code? you can override default    status check. > 2. What is "All sessions" stand for?

Right ā€¦ so sessions = number of running users, whereas the actual number of sessions on the server side (fully logged in users) may be something else entirely ā€¦ ---

You can have both matching if the last step of your scenario is logging out. Otherwise, server session will linger until idle time out. ---

Hi, Cloud you please explain detail of latency time in bad network situation? Dose latency mean network consume time? We want to calculate time without network consume time to fix the real performance issue. Thanks, ---

Latency means the time your server starts responding to a request, from the client POV. Of course it includes network, Gatling is a client. If you want the server side times, you have to measure there with the proper monitoring tools suited for your technology.
