How to test our code to send 400 queries per user per minute in Gatling

I want to limit server calls to 400. For that I need to check if I pass 400+ queries will it give me error.
And how write code for 1 user repeated 400 times over a minute.
val UIScenario = scenario("UI Simulation")
.repeat(400)
{
exec(loginScns).exec(search)
}
setUp(
delphiUIScenario.inject(rampUsers(1) over(1 second))
).protocols(httpProtocol)
Please help to sort out this
Thanks !!!!!!!!!!!!
For such as scenarios you can use Apache Benchmark tool. Here is homepage and documentation of it.

eBay API error : You have exceeded your maximum call limit

I have a table of eBay itemid, and for each id I want to apply a reviseitem call, but from the second call I get the following error:
You have exceeded your maximum call limit of 3000 for 5 seconds. Try back after 5 seconds.
NB: I have just 4 calls.
How can I fix this problem?
ebay count the calls per second per unique IP's. So please make sure your all calls from your application must be less than 3000 per 5 seconds. hope this would help.
I have just finished an eBay project and this error can be misleading. eBay allow a certain amount of calla a day and if you exceed that amount in one 24 hour period you can get this error. You can get this amount increased by completing an Application Check form http://go.developer.ebay.com/developers/ebay/forums-support/certification
The eBay Trading API, to which your ReviseItem call belongs, allows up to 5000 calls per 24 hour period for all applications, and up to 1.5M calls / 24hrs for "Compatible Applications", i.e. applications that have undergone a vetting process called "Compatible Application Check". More details here: https://go.developer.ebay.com/developers/ebay/ebay-api-call-limits
However, that's just the generic, "Aggregate" call limit. There are different limits for specific calls, some of which are more liberal (AddItem: 100.000 / day) and others of which are more strict (SetApplication: 50 / day) than that. Additionally, there are hourly and periodic limits.
You can find out any application's applicable limits by executing the GetApiAccessRules call:

You can try that out four your own application by pasting an AuthToken for your application into the form at https://ebay-sdk.intradesys.com/s/9a1158154dfa42caddbd0694a4e9bdc8 and then press "Execute call".

How to Fix Read timed out in Elasticsearch

I used Elasticsearch-1.1.0 to index tweets.
The indexing process is okay.
Then I upgraded the version. Now I use Elasticsearch-1.3.2, and I get this message randomly:
Exception happened: Error raised when there was an exception while talking to ES.
ConnectionError(HTTPConnectionPool(host='127.0.0.1', port=8001): Read timed out. (read timeout=10)) caused by: ReadTimeoutError(HTTPConnectionPool(host='127.0.0.1', port=8001): Read timed out. (read timeout=10)).
Snapshot of the randomness:
Happened --33s-- Happened --27s-- Happened --22s-- Happened --10s-- Happened --39s-- Happened --25s-- Happened --36s-- Happened --38s-- Happened --19s-- Happened --09s-- Happened --33s-- Happened --16s-- Happened
--XXs-- = after XX seconds
Can someone point out on how to fix the Read timed out problem?
Thank you very much.
Its hard to give a direct answer since the error your seeing might be associated with the client you are using. However a solution might be one of the following:
1.Increase the default timeout Globally when you create the ES client by passing the timeout parameter. Example in Python
es = Elasticsearch(timeout=30)
2.Set the timeout per request made by the client. Taken from Elasticsearch Python docs below.
# only wait for 1 second, regardless of the client's default
es.cluster.health(wait_for_status='yellow', request_timeout=1)
The above will give the cluster some extra time to respond
Try this:
es = Elasticsearch(timeout=30, max_retries=10, retry_on_timeout=True)
It might won't fully avoid ReadTimeoutError, but it minimalize them.
Read timeouts can also happen when query size is large. For example, in my case of a pretty large ES index size (> 3M documents), doing a search for a query with 30 words took around 2 seconds, while doing a search for a query with 400 words took over 18 seconds. So for a sufficiently large query even timeout=30 won't save you. An easy solution is to crop the query to the size that can be answered below the timeout.
For what it's worth, I found that this seems to be related to a broken index state.
It's very difficult to reliably recreate this issue, but I've seen it several times; operations run as normal except certain ones which periodically seem to hang ES (specifically refreshing an index it seems).
Deleting an index (curl -XDELETE http://localhost:9200/foo) and reindexing from scratch fixed this for me.
I recommend periodically clearing and reindexing if you see this behaviour.
Increasing various timeout options may immediately resolve issues, but does not address the root cause.
Provided the ElasticSearch service is available and the indexes are healthy, try increasing the the Java minimum and maximum heap sizes: see https://www.elastic.co/guide/en/elasticsearch/reference/current/jvm-options.html .
TL;DR Edit /etc/elasticsearch/jvm.options -Xms1g and -Xmx1g
You also should check if all fine with elastic. Some shard can be unavailable, here is nice doc about possible reasons of unavailable shard https://www.datadoghq.com/blog/elasticsearch-unassigned-shards/

How to put some delay after certain time interval in load runner?

I am using load runner tool for performance testing. I want to put some delay after certain interval of time like every 5 minutes.
Kindly guide me.
Please use the below code,
sleep(1000*60*5);
Example:
web_add_cookie(<bla bla bla bla>);
sleep(1000*60*5);
web_link(<bla bla bla bla>);
Pacing in run time settings
sleep(300000);
If you are adding a delay to allow a slow server to respond then you are on the wrong path
