I have 416 webservice API's to test . I am loading those url's from a CSV file . my test need to find an API which takes more than 2 sec to respond . I couldn't find a way to measure response time for an API .
I am using
Thread Users - 416
Ramp up Period - 1
Loop Count - 1
I have tried "View Results in Table" listener which shows the sample time . But the sample time does not show individual response time .
Please let me know if you find any solution ?
You shouldn't use listeners as View Results in Table in Load test because it consumes a lot of resources
this visualizer uses a lot of memory.
Use Duration Assertion instead, defined it with 2000 milliseconds in your case
Duration Assertion tests that each response was received within a given amount of time. Any response that takes longer than the given number of milliseconds (specified by the user) is marked as a failed response.
Add listener Summary report which has columns as average, minimum and maximum response time taken by a hit.You can also save this report by clicking on Save Table data button.
Also, add View Results Tree listener in which Sampler Result tab has all the details corresponding to that hit.
On the "Advanced" tab of the HTTP Request sampler (or even better HTTP Request Defaults) there is Timeouts section where you can define maximum value for establishing the connection and/or getting the response.
If JMeter fails to get the response within the time frame (in milliseconds) the relevant sampler will be marked as failed.
In order to see individual response times - add the variable from the CSV file as HTTP Request label (or prefix or postfix) - this way you will see the associated URLs in the listeners and in the HTML Reporting Dashboard :

Objective : To Use Grafana log panel to display Apache JMeter Logs for an execution, using InfluxDB Backend Listener.
apache-jmeter-5.5
influxdb-1.8.10-1
grafana-8.5.0
I am using InfluxDBBackendListenerClient for my JMeter tests and grafana to display the the test metrics data into the dashboard.
I want to use the Grafana Logs Panel, to fetch Apache-Jmeter Execution Data,
I had accomplished this couple of years back and the log panel use to look like the below image:
Unfortunately, I don't have that dashboard and want to integrate the logs to my current dashboard.My Current logs dashboard looks like this below:
Influx Query: I have used the below mentioned influx query, I know something is wrong with the query.
I would really appreciate is anyone can help me resolve this query and aid me to get a dashboard in similar format as the first image,
JMeter's Backend listener doesn't send Apache JMeter logs, here is the list of the metrics which are supported as of JMeter 5.5
15.1.1 Thread/Virtual Users metrics
Thread metrics are the following:
<rootMetricsPrefix>test.minAT
Min active threads
<rootMetricsPrefix>test.maxAT
Max active threads
<rootMetricsPrefix>test.meanAT
Mean active threads
<rootMetricsPrefix>test.startedT
Started threads
<rootMetricsPrefix>test.endedT
Finished threads
15.1.2 Response times metrics
Response related metrics are the following:
<rootMetricsPrefix><samplerName>.ok.count
Number of successful responses for sampler name
<rootMetricsPrefix><samplerName>.h.count
Server hits per seconds, this metric cumulates Sample Result and Sub results (if using Transaction Controller, "Generate parent sampler" should be unchecked)
<rootMetricsPrefix><samplerName>.ok.min
Min response time for successful responses of sampler name
<rootMetricsPrefix><samplerName>.ok.max
Max response time for successful responses of sampler name
<rootMetricsPrefix><samplerName>.ok.avg
Average response time for successful responses of sampler name.
<rootMetricsPrefix><samplerName>.ok.pct<percentileValue>
Percentile computed for successful responses of sampler name. There will be one metric for each calculated value.
<rootMetricsPrefix><samplerName>.ko.count
Number of failed responses for sampler name
<rootMetricsPrefix><samplerName>.ko.min
Min response time for failed responses of sampler name
<rootMetricsPrefix><samplerName>.ko.max
Max response time for failed responses of sampler name
<rootMetricsPrefix><samplerName>.ko.avg
Average response time for failed responses of sampler name.
<rootMetricsPrefix><samplerName>.ko.pct<percentileValue>
Percentile computed for failed responses of sampler name. There will be one metric for each calculated value.
<rootMetricsPrefix><samplerName>.a.count
Number of responses for sampler name (sum of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.sb.bytes
Sent Bytes
<rootMetricsPrefix><samplerName>.rb.bytes
Received Bytes
<rootMetricsPrefix><samplerName>.a.min
Min response time for responses of sampler name (min of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.max
Max response time for responses of sampler name (max of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.avg
Average response time for responses of sampler name (avg of ok.count and ko.count)
<rootMetricsPrefix><samplerName>.a.pct<percentileValue>
Percentile computed for responses of sampler name. There will be one metric for each calculated value. (calculated on the totals for OK and failed samples)
In order to be able to see JMeter log in Grafana you need to add it somehow to InfluxDB, I can think of the following options:
Periodically read it using JSR223 Test Elements and sending to InfluxDB HTTP endpoint using "normal" JMeter HTTP Request sampler
Come up with your own implementation of the Backend Listener which will be sending log file entries along with other metrics
I have Test plan with a transaction controller Landingpage (containing 10+ requests). since I have clicked generate parent sample I get the complete result of the process (this is desired)
Now when I run Jmeterin non Gui and open the jtl file, dont get the result of landingpage but the result for every single request.
How can I run the test plan in non gui mode but still have the result grouped by transaction controllers
I cannot reproduce your issue using default Results File Configuration:
You should see each individual request under the "Landing Page" transaction controller plus 1 extra request with the name of your Transaction Controller and its response time will be the cumulative response time of all its children.
More information: What is JMeter’s Transaction Controller?
I've executed a single request for an API in Jmeter. When I am trying to check for the latency details, I get different values of latency in View Result Tree and View Results in Table.
Sample Details in View Results Tree Listener is Load time:23202, Latency:23202
Sample Detail in View Results in Table Listener is Sample Time: 23241, Latency: 0
enter image description here
enter image description here
What can be the possible reasons for the same?
Is there any way we can get the correct latency details in Jmeter when we hit any request?
The reason for the same is that you're looking into different results of the same.
If you open .jtl results file using text editor of your choice or an application like MS Excel you will see that there is one line for each request
And when you open .jtl results file using "Browse" button in the listener of your choice - the values are the same for each request in any listener
So the situation you're describing is not possible as you're comparing not the same results as they even have different response time.

How Do I Run JMeter in Non-GUI Mode?
Suppose, I am adding some think time(Timers) in each HTTP request, but when I execute the test, in the report it shows response time as Sum of ThinkTime + actual response time.
How can I get actual response time from the result?
by default, JMeter does not include Timer's time in the response time of any HTTP sampler.
In case if you are using Transaction Controller to group the requests, then you can deselect the checkbox Include duration of timer and pre-post processors in generated sample in the transaction controller.
By default JMeter does not include the duration of:
Timers
PreProcessors
PostProcessors
into Sampler's response time unless you use Transaction Controller with Include duration of timer and pre-post processors in generated sample option selected. If this is the case and you use dynamic values in the Timer - you can consider using Sample Variables functionality to record think time into .jtl results file.
Think Time is the time taken by the user to read,
understand and take next action on the webpage.
So the time between a response and the net request
is the Think Time. This can be simulated by adding
a timer.
I have written a load test for a web application. The test script submits a request to the server via HTTP and then polls the server in a While loop with a small timer, to see when the request has been processed. The problem I am having is that in all the listeners (aggregate graph, table, etc.) JMeter only shows the time each request took and not the total time to process the job, i.e. time from initial request sent until response that contains the expected "complete" message.
How can I add something like "profiling points" which will get data onto the listeners graphs? Or is there another way this is typically handled?
You need a Transaction Controller. Put elements times of which you want to aggregate under it. Transaction controller will then appear in all your listeners. Its load and latency times will be sums of those parameters of its nested elements.
Note that this time by default includes all processing within the controller scope, not just the samples, this can be changed by unchecking "Include duration of timer and pre-post processors in generated sample".
