Kubernetes 101 - Episode 10 - Monitoring with Lens, Prometheus, and Grafana

[@JeffGeerling]

Be sure to check out the book based on this series! www.kubernetes101book.com Thanks so much for watching, to those of you who made it through all ten episodes :)

Doesn't Lens also deploy it's own resources into the cluster ? In terms of watching logs form a bunch of pods. Take a look at github.com/johanhaleby/kubetail

[@JeffGeerling]

@@DontScareTheFish Nope! If it did, I wouldn't touch it with a 100' pole. It does have some options that you could 'inject' like a custom Prometheus configuration, but that's not on by default, and if they ever tried putting that in by default I'd turn against Lens in a heartbeat.

[@neknarqo]

I must say that Operators episode was the eye-opening moment for me. It could be that the topic is more advanced than what is expected from a 101 series. I really hope there will be more intermediate content

[@DevOpsDirective]

Fantastic series, Jeff! Even having worked with k8s for a few years now, I still learned some new things and cemented a few concepts that were still nebulous!

[@EligioMerino]

Awesome K8s monitoring intro!! 👏👏 I am looking forward to learn a bit more on the alerting topic with these tools 👀

[@MichalKottman]

Bought the book, looking forward to seeing it grow. Thank you for sharing your knowledge!

[@apulacheyt]

Another excellent episode. Thanks a lot Jeff! I've tried deploying Prometheus and Grafana using the helm chart you mentioned on my Raspberry pi K3S cluster and I've got the prometheus-kube-state-metrics pod on CrashLoopBackOff. It's the only pod that's not running. Logs said: standard_init_linux.go:219: exec user process caused: exec format error │ stream closed I've assumed the chart is only AMD64 compatible. I would be really great if more of these tools were multi arch. Next step, I will try it in my other AMD64 K8S cluster. Till next time.

[@JeffGeerling]

If you're on Pi / ARM, please give carlosdp's cluster-monitoring stack a try: github.com/carlosedp/cluster-monitoring It's the same thing, but uses images guaranteed to work on ARM/ARM64.

[@apulacheyt]

@@JeffGeerling I will try it on my Raspberry K3S Cluster later. Thanks for the suggestion. Don't you think that cross platform apps compiling and OCI cross platform image building would be a great topics for future episodes?. What are the options apart from Docker build and buildx?. I will really enjoy to learn how to do that. And it will help develop Raspberry Pi and ARM ecosystems. Just thinking out loud!.

[@bluebobx]

@@apulacheyt I can recommend Saint Jeff's 😉 book Ansible for Kubernetes. I seem to remember that targeted builds were in that book. I got that with his Ansible for DevOps book and it's a good combination. Gets my recommendation! 🤩

[@makkurotatsu]

Now that's what I call a great series. Tons of useful information presented in a pleasant and calm manner. Kudos!

[@TrainWithDevesh]

Excellent video! Just what I was looking for!

[@DarianBenam]

Top notch video! 🚀

[@geisterkind1]

Hi Jeff, thank you for this series - please finish your book :) really enjoy your videos

[@devaroop]

Hey Jeff, thanks for giving to the community. Amazing series. God bless.

[@vasilypodguzov8845]

Dear Jeff, a lot of thanks for this video.

[@grzegorzbajson3897]

Great job Jeff. Again. Thank you!

[@techloading510]

Thank you for the detailed explanation. Your videos are the best 👍 I have no need for a cluster but this has helped me scope the infrastructure/tools I could use in the future 🚀

[@wilcosec]

Great series! Thank you for making it. And the operators one was my favorite episode!

[@sf2998]

Should we use Rancher and Lens IDE together or using them separately??

[@yvanhelie5324]

This is a great presentation! Keep the good works!

[@umairzubairy427]

great content, i would recommend to monetize your videos to get some ads so you can get something in reward ... thanks for these videos

[@Rienck]

Hey Jeff, I really enjoyed thid serie!Het zou geweldig zijn als je een kubernetes 102 serie zou maken. Or in English, it would be great if you would make a 102 serie about kubernetes! Groeten uit Nederland!

[@styopg]

Thank you very much, Jeff! You are very cool and amazing man.

[@mallxs]

Thanks for the book, But on a point in time i wlll bing All the Kubenetes 101 Episodes

[@romangalochkin2564]

Thanks you for your videos! Continue and do not give up.

[@orzechot]

Awesome series! Thanks a million!

[@deefdragon]

Some opinions: The operators episode could have been part of a 102 series yes. A Q&A section was REALLY needed. k8s is complicated, and a Q&A would cover some of the possible holes that people had. Diving more into deploying & customizing stuff with Helm would have been appreciated.

[@JeffGeerling]

Good points, I think a Helm deep dive episode might've been better than the Operators video. Also, I'm considering doing a separate 'Kubernetes Questions, Answered' video at some point, maybe a few videos over time. There are definitely some good ones I haven't answered from live chat and comments!

[@deefdragon]

@@JeffGeerling I think the best way to describe my thoughts on the series would be to say that it crossed between a 101 and a 103. It also would have been nice to have a consistent format on discussion of a topic or problem and then implementing the topic/solution. You discussed logging problems/options in 6 for example, but did not deploy them. 1-3 did a great job of this. some of the others as well. Episode 10 centered around the insights problem at a high level, but that was not how it was approached. k8s is complicated and there is VERY little good, *consistent* information on the topic. This series would be a great hand hold, but it still has its issues.

[@jonasgroendahl]

I just started learning kubernetes and prometheus. I haven't used Lens before but it looks a lot like Minikube dashboard. Is it the same?

[@EhrlicherEdukator]

I have just bought your book. I hope it is a good as the Ansible for Devops! Best regards from Germany!

[@SergeyTarabara]

Cool video! Thx! Tell please about logging (collecting, analyzing, alerting) in k8s in next your video.

[@SK-wf1oh]

How Can I define the period of store logs per container in Lens tool? I'm not able to chech logs from 6 h back? ???

Hi, from Bannockburn, Australia. Not live because of the timezone.

[@Adks007]

Very informative. What are your thoughts on rancher when compared to lens?

[@StephenFasciani]

Man my autism picked a bad thing to wanna go for... Autism hates abstract concepts and yet I love IT. Even with a fancy UI I struggle to wrap my brain around all the concepts... I seem to only do well in school (BSIT/4 year degree) but when I want to do something nice for myself to monitor my own application server it just goes way over my head.

How to make Prometheus storage persistent for 1 year

[@windowsrefund]

Please refrain from using the bogus term "Open Source". What you are talking about here is actually "Free Software".

[@premierde]

I am in a situation where the node_exporter in always in pending state. And the port 9100 is already occupied tcp6 0 0 :::9100 :::* LISTEN 516561/node_exporte ; After doing kill -9, it get restarted itself ( kube-scheduler). Is there a way to get rid of this & get prometheus node exporter in running state.
