[@deepakranganathan9644]

@@TechWorldwithNana I have a doubt with respect to Prometheus setup for Django applications. If we have a load balancer which redirects to three application servers where the Django applications are running. Which of these setups will work and is optimally correct? 1. Having Prometheus installed in one of the application servers and then having a job for every Django application we need to monitor and provide all three application server's Django configuration details in the targets entry in prometheus.yml? - One more doubt, in this case, is when the targets are authenticated using OAuth, how can we manage in this scenario? 2. Installing Prometheus on any server and mentioning all the Django applications details in the targets entry in prometheus.yml file? - Do we need to have ssh trust set up in this case when the setup has to be done like this? It will be very helpful if you please give some insights on this. Thanks in advance :)

Nana, you're doing a great job. Don't stop what you're doing. This is helping a lot of people.

[@TechWorldwithNana]

Thank you Noah 🙏. 😊

I second this! I'm on my second video and looking forward to more. You have put out great content. Thank you.

[@michaelhughes8413]

Agree with you 💯

[@poefpoef]

The quality of this tutorial is truly excellent. Nana doesn’t jump into solutions, but describes the problem or issue first, consistently. That helps to understand not only the ‘how’, but also the ‘why’ and the ‘what’. In addition, Nana tells a coherent story at the right pace. Kudos for this great video!

[@yapadqoi]

Probably one of the best teachers I've ever had. Wow! In a week-end, I've learned more on DevOps solutions, going through your video series, than I did in months with official documentation and reference manuals. You make things so simple and easy to grasp. Great job! Thank you so much

ty for this, i learned prometheus a couple years ago and have been somewhat managing it and it was clear to me there was a much easier way to represent that documentation. i think this is great and should sit on the front page of prometheus docs itself.

Hi Nana, you are great. You are helping many people with your knowledge and all this is free of cost. So kind of you. Can you please upload a session on airflow -- what it is, how to install it on local machine and create the DAG and run some pipelines and also possibly how to monitor the data pipelines.

[@nagaarigala]

Way of Your explanation is very nice. It is very easy to understand everyone. Thanks Nana

[@nmhmm2472]

You are such amazing talented teacher I have ever been know

[@_ashout]

Hey Nana, Not quite sure if I missed something in the video or if someone else answered already but at around 12:52, you mention that Push metrics creates a "high load of network traffic", but I don't quite understand why a pull mechanism would be able to avoid that? You still need your prometheus servers to poll every microservice that would have been potentially pushing metrics at the same frequency right? Why does the "pull" mechanism put less load on your system?

[@ImAHorseDammit]

Imagine a world where you have to sort papers and archive them. If you get sent papers all the time from a load of clients you might get a huge backlog and you are unable to keep up with all notes you get. And if you are unavailable people will come back later or perhaps not even send the data. But if you only go get papers when you can handle them, the client can write more and more stuff on the same paper that you can handle in one go instead of getting the same data in 20 different papers. I'd say it's easier to send requests than to get them. Since the requests can vary in size greatly also there is a overhead to receiving connections after a certain scale. If you are running 100VMs with a total of 500services it's not that big of an issue, but start running thousands and thousands you'll get some bottlenecks quite fast.
