Configuring Parameter for Load Testing in Production

Samples: Samples denote to the number of http request.
 Average: Average is the average response time for that particular http request. If there are 1000 samples in application then  if 2333 is average time.Then for 1000 samples average time is 2333.This value is in milliseconds.Same for min and max

Min: Min denotes to the minimum response time taken by the http request.If   for 1000 samples  the minimum response time is 266 ms. It means one http request responded in 266 ms out of 1000 samples .


Max: Max denotes to the maximum response time taken by the http request. If   for 1000 samples  the max  response time is 1100 ms. It means one http request responded in 1100 ms out of 1000 samples
Error %: This denotes the error percentage in samples during run.
Throughput : The throughput number represents the actual number of requests/minute the server handled. It is supposed to represent the load on the server .

Latency:
The time from just before sending the request until the request has been processed (request and reply assembly). In short, this should be a more accurate time from a user experience view than the elapsed field which is the time from when the request is sent until a response is received.
Response time (= Sample time = Load time = Elapsed time) is a difference between time when request was sent and time when response has been fully received.
So Response time always >= latency.

Ramp –Up Period :
For example
Number of threads(users) = 11
Ramp up period(in seconds) =  110
Loop Count = 1
110/11=10second
In Every 10 second(110/11) one request hits the server.
Starts with one request initially
Number of threads(users) = 11
Ramp up period(in seconds) = 660
Loop Count = 1
Every 60 second(660/11) one request hits the server
Starts with one request initially
Number of threads(users) = 11
Ramp up period(in seconds) = 660
Loop Count = 3
Every 60 second(660/11) 3 request hits the server
Starts with 3 request initially.

Schedular:Start and end time upto which load testing is performed.It is combined with ramp up period and loop count to simulate real  environment.
