Gatling.sh error Unrecognized VM option 'OptimizeStringConcat'

Open Gatling.bat and remove “-XX:+OptimizeStringConcat”. Now it works…

My 2 cents: either you don’t have an internet connection, or you’re behind a proxy, so you can’t access the internet directly.
If so, read the doc: https://github.com/excilys/gatling/wiki/HTTP#wiki-proxy

invisible0786 · February 25, 2014, 10:15am

Yes I am behind the proxy. how do i print dynamic parameter value on console output?

Excilys · February 25, 2014, 10:20am

WDYM?

invisible0786 · February 25, 2014, 10:24am

sorry steph i don’t understand this. what is WDYM?

Excilys · February 25, 2014, 10:48am

WDYM = What Do you Mean

invisible0786 · February 25, 2014, 11:14am

I am capturing value dynamically for field ID as follows

check(regex("""&id=(.*?)">""").saveAs(“ID”)))

now I want to print this value on console output so that I can verify it manually first?

Excilys · February 25, 2014, 11:17am

https://github.com/excilys/gatling/wiki/Session#wiki-functions

invisible0786 · February 25, 2014, 11:37am

OK Thanks.

i have defined following function in my gatling file
def selectRandomElementFromList(list: List[String]) : String = {
val rand = new Random(System.currentTimeMillis());
val random_index = rand.nextInt(list.length);
val result = list(random_index);
return result
}

now i want to use this function so that i can select a random value for following regex

check(regex(""“categoryId=(.*?)”><""").findAll.transform(selectRandomElementFromList).saveAs(“categoryId”))

however this particular step is failing with error “type mismatch; found:String Required: Option[?]”

Can you advise what wrong i am doing here ?

Excilys · February 25, 2014, 12:27pm

You’ve switch from Gatling 1 to Gatling 2, right?

First, findAll returns a Seq, not a List, so it’s:
def selectRandomElementFromList(list: Seq[String]) instead of List

Then, in Gatling 2, transform signature is not Option => Option, so

transform(_.map(selectRandomElementFromList))

invisible0786 · February 25, 2014, 12:50pm

Hurrey my problem is solved. I am using gatling 2 only and not switched from 1 to 2. really interested tool and I am really loving it. Only I found initially people may struggle little if they are not familiar with scala.

Secondly I need to focus and achieve little bit if I can integrate it with graphite and if I can monitor server specific resources etc??

I will raise more question in next few days time until i get 100 % confidence so please don’t mind and don’t be upset if I ask silly questions?

Excilys · February 25, 2014, 12:56pm

No pro, go ahead!

invisible0786 · February 25, 2014, 1:16pm

I would like a define a work load modal as follows

Rampup 50 user in 60 seconds
when all 50 users are up and running then run the whole scenario for 30 minutes
ramp down all 50 users in 60 seconds

I have defined my scenario as follows
setUp(jpetstorescn.inject(ramp(50 users) over (5 seconds)).protocolConfig(httpConf))

But in this scenario all 50 users are running only 1 iteration and then ramped down all. how I can define scenario as per my requirement above?

Excilys · February 25, 2014, 3:43pm

Wrap you scenario content in a during loop.

how to use feeder in gatling 2. don’t know but i am getting error when using feed(feeder) after .headers(headers_3) request ?

val feeder = csv(“MTUserData.csv”).circular

val login = exec(http(“TX02_TourLogin”)
.post("/servlets/com.tours.servlet.SignonServlet")
.headers(headers_3)
.feed(feeder)
.queryParam(""“procSub”"", “”“1"”")
.param(""“userName”"", “${UserName}”)
.param(""“password”"", “${UserPwd}”)
.param(""“login.x”"", “”“32"”")
.param(""“login.y”"", “”“11"”"))
.pause(47 milliseconds)

any idea?

Excilys · February 26, 2014, 2:59pm

This doesn’t work in Gatling 1 either.

feed doesn’t belong to request, it’s a structure DSL element, just like exec:

val login = feed(feeder)
.exec(http(“TX02_TourLogin”)
.post("/servlets/com.tours.servlet.SignonServlet")
.headers(headers_3)
.queryParam(""“procSub”"", “”“1"”")
.param(""“userName”"", “${UserName}”)
.param(""“password”"", “${UserPwd}”)
.param(""“login.x”"", “”“32"”")
.param(""“login.y”"", “”“11"”"))
.pause(47 milliseconds)

Hi Steph,

When login into my application then I am getting currently a window popup with message that my application is blocked by security but the work around is that if i click on OK button on this popup window then i can continue my business process. how I can achieve this via gatling?

See attached screenshot

BlockerScreenshot.docx (257 KB)

Nicolas_R · February 26, 2014, 5:18pm

Gatling works at the HTTP level … so, is there any HTTP request fired after clicking “yes” ?

invisible0786 · February 26, 2014, 5:23pm

yes after clicking on “OK” button on windows security popup i have completed my business process successfully and recorded all http traffic. but during replay it’s failing in window popup step i guess?
