Hi, thanks for this video, 'Deploy PodMonitor to scrape the produced metrics' step in Readme is same as 'Deploy the Grafana ingress' step.

Hi ! Sir Great Content. I am very new to this field and trying to learn about visualizing telemetry data. Your video was very informative, would like to know about the pipeline file editing part at 36.31 in the above video. Where to do it and how to do it and where to execute it. Please help. Thank you

yeah - it's F5 BIG-IP but we understand it's a typo.. ;-)

Hi, Thanks for this video. It is really helpful. Also I got a problem when I tried using filter with annotations and labels in processor/k8sattributes ( distibution: openshift ), I cannot able to scrape the data exactly from those annotations I used. Even I used the filter it is exporting all the data of all the pods in the openshift cluster. I'm using exporters/kafka data is emitted as otlp_json format.

Hello, Is this for observability of hipster-shop application running in kubernetes? Or This will give observability of kubernetes cluster even if there is no Application/hipstor-shop application not running??

I followed the step for installing Prometheus using helm with the parameters as it is shown in document but it is not visible and when I do it again it shows already in use.. does this Prometheus need to be installed in same default namespace or new namespace with name Prometheus?

Thanks for the video!
I have a question regarding the OpenTelemetryCollector manifest, why do you need to use the hostNetwork: true parameter?
Thanks :)

Hi, thanks a lot for this video. very interesting. I was wondering if it's possible for a collector (hosted on a dedicated cluster) to get kubernetes cluster metrics from another kubernetes cluster where applications and instrumentation is already done ?

Hi Henrik, Thanks for the great video, I have a query for k8seventreceiver, can we export k8s events as metrics using opentelemetry

[Sen-oszt]

Hi, I tried this but I do not see the Resource metrics in my logs or k8's metrics in grafana. I only see Resource logs. What can be the issue?

I feel like you don't have the letter K in your home country language coz you have a hard time pronouncing it 😄 thanks for the useful content
