HTTP Polling

Learn how to start and stop the polling

HTTP polling is an extension to the HTTP DSL, whose entry point is the poll method.

Common operations#

If you want to deal with several pollers with per virtual users, you have to give them a name and pass this name on each polling operation:

pollerName(name:String)

For example:

poll().pollerName("myCustomName");

poll().pollerName("myCustomName");

poll().pollerName("myCustomName")

poll.pollerName("myCustomName")

Of course, this step is not required if you deal with one single poller per virtual user.

Start polling#

The first thing to do is start the polling, by specifying the request and how often it will run:

every(period).exec(request)

The period parameter is from response received to next request sent.

For example:

exec(
  poll()
    .every(10)
    .exec(http("name").get("url"))
);

exec(
  poll()
    .every(10)
    .exec(http("name").get("url"))
);

exec(
  poll()
    .every(10)
    .exec(http("name").get("url"))
)

exec(
  poll
    .every(10)
    .exec(http("name").get("url"))
)

Stop polling#

When you don’t need to poll a request anymore, you can stop the poller:

poll.stop

For example:

exec(
  poll().stop()
);

exec(
  poll().stop()
);

exec(
  poll().stop()
)

exec(
  poll.stop
)
