When running a training or mentoring session, people often ask what runtime settings they should use; as if there is a magical list of settings that will always be correct for any testing situation. Obviously you select runtime settings that are appropriate for what you are trying to achieve with your test, but the funny thing is that there are actually a small list of settings that are usually appropriate for most situations. Read on…

General: Run Logic

Whenever I am using a vuser type that allows multiple actions in a single script, I will create a separate action for each business process and put appropriate percentage weightings on each action. It is very unusual to have to do anything more complicated than this. I don’t usually use the “sequential” option or create blocks unless I need to have fractional percentage weightings for a business process – percentages must be integer values, so to run a business process 0.1% of the time you could create a block that runs 1% of the time, and put an action in the block that runs 10% of the time.

It’s also rare to set a script in a scenario to run for a specified number of iterations (mostly done by time or set to run indefinitely). Generally “number of iterations” is only used when running the script in VuGen.

General: Pacing

  • “As soon as the previous iteration ends” is used when running in VuGen or when loading/verifying data. Do not use this for load testing
  • I have never seen the point of the “After the previous iteration ends” option. Why would you want to run an unknown number of transactions per hour against the system?
  • Don’t use the “At fixed intervals”. If something causes your users to become “in step”, they will tend to stay that way and continue to all hit the server at the same time.
  • “At random intervals” is definitely the way to go. Obviously for your users to create a certain number of orders per hour the iteration time must average to 3600/num iterations in an hour. Do not make the lower boundary value any bigger than the maximum time it takes to complete the business process, or you will end up creating less transactions per hour than you intend to.

General: Log

  • Logging creates additional overhead on your load generators, and can create huge log files.
  • I log absolutely everything when debugging in VuGen.
  • When running the script as part of a scenario, I leave extended logging on but change the logging to “Send messages only when an error occurs”. This gives a little more information than turning logging off entirely, and won’t create any additional overhead while everything is running smoothly (and if the system is not running smoothly you are going to need to stop the test and investigate anyway).

General: Think Time

  • Just like the pacing setting, I think that it is a good idea to put some randomness in your think times.
  • I use a random percentage of 50-150% of recorded think times.
  • Use “Ignore think time” if you are debugging in VuGen or if you are loading/verifying data.

General: Additional Attributes

  • This option is ignored by most people. It is used to create a parameter with a given value without having to edit the script (as runtime settings can be overridden in the Controller).
  • In the screenshot I have created a parameter of ServerName with the address of the test environment. If you were testing in more than one test environment at a time, this would make save some time.

General: Miscellaneous

  • Continue on error is generally only going to be used if you have written code to do something when you encounter an error. Usually the default behaviour of ending the current iteration and then starting the next one is sufficient). I don’t advise anyone to try to write a script that handles errors in the same way as a real user because it will create a lot of additional work for very little benefit, but doing something simple like writing some useful information to the logs and then calling lr_exit(LR_EXIT_ACTION_AND_CONTINUE , LR_FAIL) can be useful.
  • “Fail open transactions on lr_error_message” should always be ticked. If you are raising an error, you should fail the transaction step that you are performing.
  • “Generate snapshot on error” is useful. If it is a web script, any error messages should be added to your content check rules.
  • Run your virtual user as a thread unless you have code that is not threadsafe or there is some other reason to run your virtual users as a process. The overall memory footprint on your load generators will be higher if you run as a process.
  • I never use the “Define each action as a transaction” option. If I want a transaction in my script I will add it myself with lr_start_transaction.
  • I never use “Define each step as a transaction” either. If it is a web script, I can use the transaction breakdown graph to get this information, otherwise I will add the transactions myself.

Network: Speed Simulation

  • Not all vuser types have this option available.
  • Most of the time my virtual users will use the maximum bandwidth.
  • If I want to emulate users with bandwidth constraints, I will do this in a separate scenario.
  • Google calculator is handy to calculate bitrates if your bitrate is not available from the drop-down list e.g./ “256 Kbps in bps

All of the following settings only apply to web-based scripts. Each vuser type will have its own runtime setting options. It is important to know what they mean and how they will influence your test results before running any tests that you plan to report on.

Browser: Browser Emulation

  • Some people get confused by the User-Agent (browser to be emulated) setting. If 90% of your users use Internet Explorer 6.0 and the rest use Firefox 1.5, you don’t have to change the runtime settings for your users to match this. All it changes is the string that is sent in the “User-Agent” field of your HTTP requests. This is completely pointless unless your application has been written to serve different content to different browsers based on the User-Agent field.
  • TODO

Internet Protocol: Proxy

  • Generally people won’t be using your web applications through your proxy server, so it shouldn’t be part of your test either.
  • If you start getting errors that are due a proxy server rather than the system under test, it will just confuse the people who have to fix the problem.
  • A proxy server will also make IP-based load balancing ineffective.
  • If it’s an intranet application and everyone will be using the application through the company’s proxy, then the proxy server should be explicitly declared to be in scope for your load test. You should make sure that you have an identical proxy server for your test environment, or that you have permission to be generating load on a piece of Production infrastructure.

Internet Protocol: Preferences

  • TODO

Internet Protocol: Preverences - Options

  • These settings are default values specified by Mercury, rather than being inherited from the web browser that is installed on your workstation. Generally you will not need to change them, but be aware that they are here.

Internet Protocol: Download Filters

  • Download filters are a quick way of preventing your scripts from downloading content from certain URLs or hosts/domains.
  • I generally use this feature when the web application in the test environment contains third-party images used for tracking website usage (e.g. images from Webtrends or Red Sheriff etc).
  • I think it is better to specify which hosts your script is allowed connect to, rather than which hosts your script can’t connect to (because it’s easy to miss one accidentally, or the application may change and refer to a new third-party domain).
  • Use web_add_auto_filter if you want to specify this in your script rather than your runtime settings.

Internet Protocol: ContentCheck

  • I have talked about Content Check rules before; I think that if you aren’t using them already, then you are not getting the most out of the LoadRunner feature-set.

    Hi,

    This update was useful as it helped me understand certain run-time features which I wasnt using so far. Thanks!
    I have one doubt regarding one run-time setting that you have mentioned. Under the Logs – > Extended Logs, you have selected all the three options, dont you think for a test with longer duration (running into hours) and for large number of users this could be an issue as this would in-turn generate lot of data which might not be actually required?

    Thanks,
    KK

    “Whenever I am using a vuser type that allows multiple actions in a single script, I will create a separate action for each business process and put appropriate percentage weightings on each action.”

    I have been advocating this for years. As we consult for new clients, and help them improve their performance testing processes, this is one of the items that I advocate under performance testing. I usually find they create one script for each click-path or BP, and these dozens of scripts at the same time, or worse, one at a time. Using a single script with action-weighting helps force the tester to get a thorough load on his system, simplifies increasing user load (you only need to increase VUsers on one script, not 30), and simplifies test management.

    I think this item is worth post all on its own.

    Overall, excellent post. This needs to be a Top Page.

    Nice work.

    Hi,

    Is there any way to record Window download box in Loadrunner 8.1?

    I tried many things butno luck,it seems that its not recording that download dialog box.

    When I click on “export” tab, download dialog comes with 3 option:
    1. Open
    2. Save
    3. Cancel

    I’m choosing Save but nothing getting recorded in Loadrunner.

    Please help.

      Hi Deepanshu ,

      For download the file it will work by load runner.
      You do onething first check manually the size of the file.
      Check manually in output log in that transaction the file size.
      !00% its working by load runner.
      If you want to see the size of the file through load runner then you use the function Web_get_init_property.

      About youe query that is save,open ,cancel that is Client side Activity.

      Thanks

    Great post, but I have an unrelated question. When purchasing a load testing software package, how do you decide what number of vusers you should get a license for? Is there some rule of thumb I should use to calculate this number? Our highest volume app is a student portal, with a max of 10000 successful user logins with in an hour. Our total student population is 50-60K. Based on these numbers can you determine a good number of vusers we should purchase. I know that 500 vusers can translate to more than 500 “real users”. Any help would be greatly appreciated.

    3. What dictates the Network Buffer Size?
    4. For a best practise, how will we know what the size should be, before test execution?

    Is there any way to record Window download box in Loadrunner 8.1?

    LoadRunner (Web HTTP protocol) records the HTTP traffic between the client and server. It does not record GUI actions. The download box is a GUI feature of IE and selecting the save or open options have no impact on the client-server communication. This means that you cannot record the download box and it has no impact on a recorded load test script.

      In standalone mode only we can choose the browser what ever we want to reocrd the script. but if you are running the scenario in controller/performance center it will automatically invoke the default browser to simulate the load on server

    Hi,
    I am new to loadrunner. But I am facing a wierd problem while recording. So I would appreciate any help regarding this.
    I have downloaded the LoadRunner 9.1 Evaluation version from the HP site. I am trying to record opening a report (in a new window) in a Reporting platform. But looks like only the frame of the report is getting recorded but not the tabular content in the report.

    These are the step I followed:
    1. In VUGen, I openned a new script and chose Web(HTTP/HTML)
    2. Then just started to recording as an ‘Action’
    3. I stopped recording when the report came up with all the data, in the new window
    4. When I replay it on the report frame come up but not the data.

    Is there any initialization or any extra setup I can do to solve this.
    Appreciate your help.

    You don’t think if we don’t enabled extended log -> Data Returned by server, we are not in position to check why some users were failing at a particular page.
    Sometime it happens that error comes when load is there on application.
    But when you check manually then application works properly.

    Excellent information. It would be nice if you can fill the <<TODO sections also. Regarding the section

    “It’s also rare to set a script in a scenario to run for a specified number of iterations (mostly done by time or set to run indefinitely). Generally “number of iterations” is only used when running the script in VuGen.”

    I think the number of iterations are useful when we run with the option “run until completion” in controller.

    “I have never seen the point of the “After the previous iteration ends” option. Why would you want to run an unknown number of transactions per hour against the system? ”

    There is actually a very good reason for this option if you’re doing stress testing – by which I mean testing where you increase the load the system is under and observe how response times increase. With this setting you can in theory achieve a stable rate of throughput even though part of the system is 100% utilised – the longer input rate of transactions reaches an equilibrium, even though you can’t predict what that rate will be.

    If you don’t use this setting, you’re just thrashing the system as hard as it will go, and this will tell you nothing about the behaviour under stress. Think of it simulating a real user – just because a page takes longer to get served to the user wouldn’t normally mean they would respond to it quicker.

    Hello.

    Avery helpfull post indeed!

    Just be aware of changes applied to Scenario you are running.

    This is: When you already have an existent scenario created and /or “saved” ypu cannot used again if you modify the scripts over Run Time Settings.. in a strange way.. Scenario gets married with an specific version of your script (the one wich it was created with) and even if you perform canges over any of the scripts for tat scenaio WILL NOT BE APPLIED.. I just found this out. So if anyone is having problems with that should try to use a NEW scenario or well not just apply changes over existent script and save it as NEW script “Save as”.

    Hope this helps

      To bump up the cache size, use the Replay run time settings for logging, advanced, and set the “size in KB of the log cache”.

    Hi Stuart

    Regards from Mexico! I have a doubt, about is possible in CITRIX Protocol evaluate the response from emergent screen and continue with other actions and return to the original script code, I tryed this based on if is succesful the transaction and write in a file errors, but the request is. If error take actions and restart with the next iteration and test record.

    Hi Stuart,

    In our case, we deal with a WPF Client based on .Net 4.5 and WCF Asynchronous Web Service calls for every Business Flow(typically a Transaction like Login, Save, Open..etc) Each of these Actions have, on an average, say 10 asynchronous web service calls.

    Ideally since the calls are asynchronous, we have should be considering the call that takes the max response time as the time for the entire action to be completed. Right?

    Now here comes a tricky situation, if some the calls become synchronous then how can we track them and their response times?

    So far we have been tracking all of this behaviour via Fiddler’s Timeline feature for every single flow.

    Is there any better way of doing it from LoadRunner
    like Web_Concurrent_Start()..but I came to know about a limitation that we cannot capture individual webservice calls using the above function.

    Please suggest how to effectively capture response times of asynchronous webservice calls

    We are using LR 11.52

    Hi,

    vugen: 11.04
    Controller : 9.1
    IE:8.0
    Protocol : web click and script (GUI based script)
    Application doveloped on javascript and Jquery

    we recorded few scripts one appliaction (Javascript and Jquery based application) six months back those are working fine vugen and contorller

    Benchmark:
    Throughput: 5,696,380,731
    Average hits/second: 107,111

    Devlopment team changed now UI for application by using the new jquery JavaScript library (making heavy use of this new jquery version in new release). now for all scripts i modified the code for few transactions. now scripts are working fine.

    but issue is Throughput, hits and passed transactions are much less and the transactions response times are much slower.

    throughput: 3,075,974,896
    Average hits per second :26.974

    Note we manual checks during the last load test and the application was responding fast (around 1 sec response time). The load test shows at the same time response times of up to 49 seconds.

    Additionally we did a load test with only one vuser and one transaction per scripts and measured the response times. These were then compared by manual measurement done by the dev team (see attached). Again LoadRunner was showing much higher response times which should not be the case.

    could you please help on this issue.

    Thanks in advace,

    Hi All, Am getting 500 internal server warning message is coming when application launch. Do u hve any solution?

    • Stuart Moncrieff July 14, 2015 at 4:47 pm - Reply

      If the HTTP 500 error occurs when you use the application manually (check your VuGen recording/code generation log), then it is a defect with the application under test.

      If you are getting the HTTP 500 error when you run the script with a single user, then there is something wrong with your script (missed a value that needs to be correlated, bad data, etc.).

      If the HTTP 500 error only occurs under load, then ask yourself if the load you are running is realistic (hopefully you did a Workload Modelling exercise). If it is realistic, then there is a load-related problem with your system under test. If your Peak Load workload model is not realistic (e.g. waaay too much load), then re-test with realistic load, and see if the problem is still present during your stress test.

      This is not a problem that you should *fix* by changing your script’s runtime settings.

    Hi Stuart,

    I am encountering with some error in LoadRunner Controller. However my script works fine with 50+ iterations. Please find below the error snippets as follows:-

    2 -79992 Action.c(7): Error: Failed to find SapGui component by ID “sbar” 7 Cntrl 7 1 1
    2 -79984 Action.c(82): Error: Failed to get the “VerticalScrollbar” property of SapGuiComponent “TableControl” 1 Cntrl 1 1 1

    2 -79906 Action.c(109): Error: Failed to press button “Release (Ctrl+F1)” 16 Cntrl 16 1 1
    2 -79638 Action.c(82): Error: Table – Failed to fill with data from Table parameter “{data}” 10 Cntrl 10 1 1

    As per as I am concerned with above errors, specific component is not loading at that moment when controller execute the script with multiple VUsers. I am doing load testing of SAPGui app. Response time is intermittently high.
    I tried to increase/decrease lr_think_time but it didn’t help out. Could you please help me to eliminate those errors?

    Hi Stuart,

    I had a question regarding the “Bandwidth Simulation” but don’t seem to get answers anywhere.

    If I have a test with two injectors each running 50 users each (total 100 users) and if the bandwidth is set to 512 Kbps, what is the treatment? Does every user get 512 Kbps raising the total possible bandwidth to 512*100 or is shared by all the users i.e. 512/100.

    Any pointers will really help.

    Thanks.

    Hi, Normally we performing the script in HP ALM and results also generated to open in HP Analysis tool. But there am having few questions:

    1.Passed transactions are equal for the entire time we setup in scheduler(inclusive rampup/steady state/rampdown)
    2.Total duration of the test performed 1hour. Is that need to focus only steady state where all the users are concurrently hitting to server. Bcoz, If we can calclulate one hour this much transactions were passed and then will expect this time will be these many transactions going to achieve. Is that the SLA deriving?
