JMeter tutorial 18 - How to monitor server health using Perfmon Plugin | GUI Mode

This is the eighteenth video of JMeter Tutorial series which covers how to monitor server health using JMeter plugin- Perfmon
Learning:
server - machine where Application Under Test is hosted
Steps involved in performance testing:
• developed test script
• performed execution
• analyze the result parameters:
response times:
min
avg(expected - 5 sec; actual - 30 sec)
max
median
90% line
Etc
This higher average response time might be because of server issues
Parameters to analyze on the server:
• CPU usage
• Memory
• Disk IO
• etc
How to analyze the issues with server?
using JMeter plugin - Perfmon
Perfmon consists of :
• Metrics collector listener
• Server agent
Download perfmon -

Download plugin manager -

Server agent - need to be installed on the server where application under test is hosted

Nice video, it will help to who are need to work on Jmeter Perfmon Metric

[@qualityassurancelab7764]

Thanks Midhuna , Happy Learning!

[@ravikrishnanthangavel9511]

Great Video..

[@Leenalee2230]

Your teaching was awesome, please do the videos with recent jmeter version please

[@vidulamodh1147]

Nice explanation. I am trying to use port other than 4444 which is open but facing error... Please let me know how can I use other port?

[@MrJosephklouda]

Well, so jmeter and server agent must run on that server when there is database on server too?

[@amithdas1431]

Nice video, want to learn performance testing from youso any batch going on this ?

[@user-mk7lt8kz2d]

Nice video, I have two questions: 1. Is it safe to install sever agent on server? 2. If memory usage is high then which configuration need to update similar for CPU usage.

[@user-mk7lt8kz2d]

Nice, Video I have 2 questions: 1. Is it safe to install server agent on server? 2. If CPU or memory usage is high what configuration need to change?

[@ravikrishnanthangavel9511]

could you please guide me as to how i can find the server port number?

[@harishkadambala8748]

please make a video on how to send these results to excel file

bro have you got any help i have same issue if you have solution then help me

[@mubeencht786]

Hello, Can we just check if any server is Up and Down and report its status through email? Please assist

[@qualityassurancelab7764]

To check if the server is up or down, send the request to the server using Sampler such as HTTP Sampler. If the Response is 2xx OK(checked from Listener), the server is up, else the server is down. Accordingly you can send email using SMTP Sampler. References - SMTP Sampler - kzbin.info/www/bejne/j6bZdZWHidCahKM HTTP Sampler and Listerner - kzbin.info/www/bejne/a3ObiaWKlp6Ba6c

Hi, startagent batch file open after enter but that is blank, what i do now?

[@hanglethi9999]

Thanks for your sharing, this video is so helpful to me. Can u have a question? I see in your video u set the current server is your localhost, if I wanna to test the real server machine I will type the lôcalhost machine IP and do the same right?

[@qualityassurancelab7764]

You are welcome! To test the real server, you will provide the Host/IP and Port of that particular server.

[@hanglethi9999]

Quality Assurance Lab thank you for your response, Can you help me with the an other question?. Iam dealing with the Thread users and ramp up. I have read a lot webpage to understand the relation ship between them, but it is so complex to understand to me. My question is if is possible to set 1000user with 1s rampup, as I known each vitual users will start each second so if I set the ramp up is 1s is not possible, right? But if I set 1000 users with 1000s(ramp up) is ok, but it takes a lot of time to finish the test,

[@qualityassurancelab7764]

@@hanglethi9999 Ramp Up period denotes how long JMeter should take to get all the threads started. If there are 1000 threads and a ramp-up time of 1000 seconds, then each thread will begin 1 second (i.e. 1000/1000 Second) after the previous thread started. Hope this helps, please let me know for any further query!

[@hanglethi9999]

Quality Assurance Lab thank you for your replying. Can I ask one more quétion, about number of threads(users)?: for example I have 1000users in the Database, and will do stress tét for 1000users to login the same time into the system. I will create the number of thread is 1000users and 1000s rampup with 1 lôp, that is correct for 1 screnario?

[@udaysiddu2096]

my server agent shutting down as soon as I started the JMeter test, any solution ?

[@ishallnotbenamed0810]

2:30 who’s gonna tell or where will we get this information that average should be 5 sec or any value. Actual result we can find anytime but just to verify actual vs expected, that will be the matter of concern. Thanks in advance

Senior DB engineer or any lead engineer responsible for the development. As per rules some analytics data should be provided by product owner to know the real-time usage.

[@prathameshsawant656]

Please make video perform using Non-gui mode

[@qualityassurancelab7764]

Sure, I will make the video on Perfmon using NON-GUI mode soon

Hi, You can now check out the video of Perfmon using Non GUI mode - kzbin.info/www/bejne/kHykdXmflJ58mMU

Can you please help? I'm trying to do Server Performance Testing in Jmeter - 5.4.2 via PerfMon - 2.3. But when I try to run the bat file of startAgent - 2.2.3 it just opens for one moment and them closes (Note that I've JRE version 1.8 installed). When I tried to open the file via cmd directory command it's giving me the following error: `ERROR: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory I've tried to install the 2.2 version of startAgent. I've tried to put the startAgent in the same directory as JMeter. I've tried start it by disabling Firewall and Anti-Virus. But nothing is working. I tried to do some related research regarding this error but there isn't many solution that I have found to be useful.
