Hey Abhishek your videos are really amazing ,you are the only person explaining perfectly each and every concept that are useful in devops journey , even in the paid tutorials they I'll just explain the installation basic stuff , really appreciate you for your free videos ,coz your videos are the perfect answer for lot ppl who want to pursue devops and not sure how to proceed further I'll highly recommend for every one to follow your videos to explore in devops .
@@AbhishekVeeramalla first of all thanks for all these detailed vedios. It would be helpful if you could make a vedio on Kloudfuse too. Working on a requirement where we have to migrate the existing dashboards from Grafana to Kloudfuse.
Great Content. After installing Grafana and adding Prometheus as a data source, if needed, we can also view the default query directly from the panel menu: Click on the three dots in the top right corner of the panel. Select 'Edit.' In the 'Metrics browser ' section, contains the query used for retrieving the data.
Crystal clear explanation. .Sir. Haven't seen someone who explains to this extent. Thank you very much Sir.. for making our daily work understandable and easy..GurudevoBhava🙏
Hi Abhishek, I hope you are doing well. I wanted to request you to create separate video on Prometheus and Grafana to integrate Prometheus metrics into the Node.js backend and use client libraries to expose custom metrics like API response times, request counts, and error rates. Thanks!
So many hiccups while trying to get the Prometheus, Grafana and Kube-State-Metrics to open up in a browser. Finally, after different ways of solving it, I completed this session successfully. Thankyou for this session Abhishek. Learnt a lot from this one.
After exposing the cluster via a NodePort, I am unable to access the application from outside the cluster, such as opening it in a browser. I am using Windows 11 Home Edition with Docker Desktop as the driver. I have encountered this issue since services class. I kindly request your assistance with resolving this matter. @AbhishekVeeramalla
It is more clear than 9 hrs udemy vdo. If you created 2nd part of this vdo.. please provide link in this vdo itself . You have explain what really a new developer needs. Very understandable.

Hey abishek, just continue another video on Prometheus like Create a basic application in kubernetes like production environment. monitor the application trigger some basics alerts in the alert manager. This will be very much helpful for all
great job, stopping and listening I am working on it, but slightly faster, some places you will touch but again you will push that will explain later. Even though I expose the prometheus and the grafana but I couldnt expose, might be becoz I was working on the ubuntu and then trying to open on the windows browser, as I do not have the internet on the ubuntu side, thx
Your Training Explains What How Why aspects of concepts. awesome. Will you able to upload some training/insight on Helm Chart, Azure Dev Ops and Azure Dev Ops Developer certification(AZ204).
Hey, the video was very instructive. Can you please share your thoughts on how to keep the grafana data sources and dashboard stored and mounted along with the grafana pods? Setting up this by the UI is a good way to start, but I wonder if there is an easy way to recover it when the pods get recreated (in case of error or shutting down the cluster, for instance). Thanks
Hey Abhishek the session was really insightful and loved the way you explained the things will be waiting for further video where we get to see the creation of the metric server and adding it to the config map file of prometheus server !
It's really an informative tutorial. I have a small doubt 😊 Suppose,if the Prometheus installed outside the kubernetes cluster, what all the steps we need to do for the k8s monitoring.
Hey Abhishek, thanks for explaining all these installation processes in detail, just one doubt, if we are using AKS cluster, which IP can I use while port forwarding Prometheus????
Thanks for the wonderful session Abhishek. I have 2 queries Abhishek 1. If you're installing Minikube on your aws Ubuntu Ec2 instance , what will be the default driver you should take like Docker or another one ? 2. What type of Instance like t2 micro or medium required for installing this minikube and run your kubectl services. Thank you
Hi .. Minikube can run on AWS .. no doubts but your free instance has very less resources. So may be you should go with medium or any other size but that will incur some costs.
Thanks for your all your effort’s How to resolve the Prometheus OOM kill issue ? If we deployed kube Prometheus stack in our k8’s cluster And it is possible for volume expansion dynamically ? If volume has full with 90% like that Just give me some hints Anna ?
In managed kubernetes like aks,eks,gks, there is everything managed by providers like scaling in pod level,node level,and even cluster also scaling and managed by providers right so out of all things why we need monitoring particularly on managed kubernetes architecture. Could explain that, this question i faced from the interviewer. What are things we have to do using monitoring tools like Prometheus or grafana.
Tools like Prometheus and Grafana provide the capabilities needed to collect, visualize, and act on key metrics, allowing you to maintain operational visibility and proactive management of your Kubernetes environment.

21:05 Prometheus learnings Error: if we use docker as driver on linux, we unable to access the prometheus even after exposing the service type as nodeport. Solution: used command “ minikube service prometheus-server-ext “ which provided url as output to access the prometheus. Because when using docker driver on linux, the terminal needs to be open to run it. Once you stop the tunnel for service. It won’t be able to access. it is better to use virtual box(windows)/ hyperkit(mac) as driver for minikube to access prometheus
Thanks for the great session Could you please help me on below. If we have 15 AKS/EKS, then 1. Do we need to install the Prometheus agent on 15 AKS/EKS as a pod via helm? OR 2. Does Prometheus need to be installed on a single EC2/VM & Prometheus will pull the metrics from AKS/EKS?
Hi Abishek great video. Good explaination. I have one doubt what if dev team wont agree for writing metrics. is there any altenative? or we can use node exporter for application?
Abhishek nodeport use krte h jb to minikubeip:port pe terminal se access ho jati h application. But browser se ni hoti access . Browser pe bhi honi chahiye na?? But localhost:port pe ho rha access instead of minikube ip🙃 (practising on local with Ubuntu lts)
Hi @Abhi, Lets assume if Prometheus is on ClusterIP mode, will Grafana get the Metrics..? As per my understanding Nodeport Configuration is just for accessing Prometheus on Browser. Correct me if i'm wrong.
Bro, There are No correct videos available to connect the Prometheus to trigger alerts to slack or email. Can you please do video on Alert Manager? It helps a lot to so many people.

Any idea about chatgpt in devops
Hi .. I made a video on chatGPT and my views on it. Please check
Hi @Abhi, Lets assume if Prometheus is on ClusterIP mode, will Grafana get the Metrics..? As per my understanding Nodeport Configuration is just for accessing Prometheus on Browser. Correct me if i'm wrong.
node port is used for accessing outside the cluster

Thank you ^^
Bro, There are No correct videos available to connect the Prometheus to trigger alerts to slack or email.
Can you please do video on Alert Manager? It helps a lot to so many people.
Sure, thanks for the suggestion
Very Very Nice and Detailed explanation Sir, Thanks a lot for your efforts and hardwork🙏
Most welcome !!
Hi sir, Thanks for sharing information. I have doubt. How the kube-state-metrics pod is created? is it created by default when we install prometheus?
