Hi Pavan, Happy to share with you, that I got an offer with 80% hike.

[@PavanElthepu]

Wow, many congratulations💐💐. So happy for you. Would love to connect with you. Please connect with me on LinkedIn when you get some time

[@mgs9452]

I totally agree with the previous commenters that approaching promql from the standpoint of sql is golden - it likely covers 90% of the target audience for the topic. It certainly worked for me like a charm. Thank you.

[@madlim8169]

Its cool that you compare it with SQL query, much more easier to understand how PromQL works, tqsm

[@patilsanika7699]

Simply great explanation. Want more on histograms and and their actual visualisation in Graphana.

[@ivanmclennon]

I'm currently struggling with a task where I need to extract metrics for OpenStack VMs from prometheus, this was very helpful for my understanding of PromQL basics, thank you. Will definitely be checking out your other content! 👍

[@DungPham-fh7ck]

Thanks for your effort put in K8S & Prometheus Series, this helped me out a lot :)

[@swaroopjoseph8085]

Awesome simple to understnd. Thanks a lot!

[@mallikarjunkonemane6908]

Nice tutorial sir🔥🔥 Need more Vedios in depth vedios on Prometheus and Grafana

[@PavanElthepu]

Sure. Stay tuned!

[@muradheyderov]

Thanks for great explanation

[@samipdaveyt]

amazing explanation brother.. salute ❤

[@PrashantSingh-un6yj]

Very good tutorial and understand rate,irate and increase function. please make tutorial for summary and histogram :)

[@PavanElthepu]

I already made a video on Histogram and Summary Prashant. Here is the link: Prometheus Custom Metrics kzbin.info/www/bejne/mXO5np55n7SUaZo

Desculpe meu inglês e ruim, gostei muita da sua explicação, estou trabalhando recentemente pra criar dashboards de um aplicação e tinha várias dúvidas de quais funções de agregação usar, no seu vídeo ficou bem claro como usar.

[@PavanElthepu]

Translation: Sorry for my bad English, I really liked your explanation, I'm recently working to create dashboards for an application and I had several doubts about which aggregation functions to use, in your video it was very clear how to use them.

[@PavanElthepu]

Thank you very much. Happy Learning👍

[@JackReacher1]

18:47 Why are you calculating the sum in the query, shouldn't it just be rate for Traffic and Error Rate? In Latency shouldn't it be response_duration instead of request_duration?

[@vijaykumarreddyt3287]

Hello pavan, some metrics are not there or not being collected in my AKS cluster. I recently deployed latest prometheus-stack. I used same scrape configurations used in my older AKS clusters there it is working but here some metrics are not being collected. Also, one difference i observed is under service discovery page in prometheus, for some services, targets column/label is showing as droped. Could it be the reason why some metrics are not being collected?

[@ABB0S]

The question is, if prometheus accepts requests from port 9090, can it show all requests, not in kubernetes on the backend, but in regular microservic, thanks in advance for the answer

[@PavanElthepu]

Yes, provided you configure accordingly

[@itz5296]

at 11:20 how is it last 3 mins? why (10:01:00) was not included?

[@softwaretitbits5849]

Is there a PromQL equivalent to the SQL query `SELECT COUNT(DISTINCT user) FROM ServiceLevelIndicator_milliseconds_count WHERE time BETWEEN @from AND @to`? Trying to create a distinct user chart over time.
