How to Monitor Metrics in jmeter

 

Sub: They are two things in on-prime one is with overall CPU and memory i.e., server-level

another one is to validate the process level i.e, PID while checking with TOP command in Linux or 

monitoring in permon in windows.


1. For monitoring Linux server level we can use "SSHMon Sample Collector" which

- sar -u 1 1 |awk '/^Average:/{print 100-$8}' For CPU

- sar -b 1 1 | awk '/^Average:/ {print 0 + $2}' For I/O

- sar -S 1 1 | awk '/^Average:/ {print 0 + $6}' For SWAP

    This collector gets the samples with out agent and these are for global Samples for the hosts


2. For Monitoring Individual processes like tomcat, notification microservice, Orientdb service, and java services we need to install Perfmon agent in Linux servers.


Steps to install perfmon :

1. create a folder and give full permissions like sudoers and download the software from wget

 wget https://github.com/undera/perfmon-agent/releases/download/2.2.3/ServerAgent-2.2.3.zip .

2. unzip ServerAgent-2.2.3.zip

3. sudo chmod 777 startAgent.sh

4. sh startAgent.sh

in JMeter you can get the details from perfmon



in the command : pid=9843:percent PID is the process id

Convert Swagger apis into jmeter script

Method #1 1. Download "openapi-generator-cli-7.9.0.jar" from https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/ 2. get the json file from swagger 3. execute the below command in cmd prompt  java -jar openapi-generator-cli-7.9.0.jar generate -i sampleAPI.json -g jmeter  Note:  java should be  in env variables and jar be in  the same path Method #2 import to Postman and export each API with the curl command copy the curl command and Jmeter->Tools->import from cUrl-> place the command and import. Note: Manual effort and recommended for specific APIs

Jmeter Preprocessor to add Dynamic parameters

Image
sub: one scenario need to capture the data from previous request and pass as a parameters in jmeter Problem: but key and pair both are dynamic and very huge values. we can't handle each parameter as below Note: Here Key and values both are dynamic Solution : we need to capture all the respose data and segrigate and pass through JSR223Preprocessor. Here is the solution. Step1: Step 2: Modify the request Add JSR223Preprocessor in the request //int count=Integer.parseInt(vars.get(“paths_matchNr”)) //log.info “parameters count” + count //vars.put("JsonResponse", prev.getResponseDataAsString()); import java.util.regex.Matcher; import java.util.regex.Pattern; import java.text.*; import java.util.*; //Paths Data List result= new ArrayList(); def count = Integer.parseInt(vars.get("ALLVALUES_matchNr")); log.info("count=" + count);//83 //["#31:218","#62:1","#61:1","#63:1","#31:2...
