Support metrics API

[ijl]

dashboard should read from the metrics APIs in order to be compatible with future kubernetes versions.

heapster is being deprecated (kubernetes-retired/heapster#2022) in favor of metrics-server (https://github.com/kubernetes-incubator/metrics-server).

The current heapster or metrics-server releases can provide the metrics APIs (https://github.com/kubernetes/community/blob/master/contributors/design-proposals/instrumentation/resource-metrics-api.md). So a single client implementation can support both on I think kubernetes 1.7 or above.

cc #2976, #1310

I can start working on this.

[bryk]

Awesome, this is yours then. Enjoy :) Talk to me or @konryd on slack if you need any help.

[gjmzj]

@ibrasho looking forward to your good news.

[ibrasho]

I hadn't had much time to work on this in the past couple of weeks. I'm expecting to be able to put more time into it soon.

I'd appreciate someone with good understanding of the current implementation to run ideas by on Slack or email.

Or just use the thumbs up reaction to the original issue post to bump it up...

Since this didn't make it into the latest release, is it still planned to replace the dependency on Heapster with the metrics API? (@ibrasho ?)

We're having to run Heapster along-side metrics-server in our 1.11 cluster just for the dashboard 😬

[leezout]

Any news on that ? As right now using k8 1.11.3 and the latest version of the dashboard/heapster/influxdb
I am unable to get the metric system to work.

Metric client health check failed: the server is currently unable to handle the request (get services heapster). Retrying in 30 seconds.

[nicroto]

I just want to add that those additional dependencies take quite a bit of resource, too. I hope you will be able to switch to the new API soon. Thanks for working on this.
Cheers!

#3504 Is ready to be reviewed. Please bring any criticisms (constructive or otherwise) and we'll hash this out. :)

@weiqiang333 对不起，标准语言是英语。如果您不会说英语，请使用翻译服务。 (And sorry for my terrible Chinese... I simply used Google Translate...)

[chiefy]

As someone who has deployed dashboard w/ heapster, coming back here and trying to figure out if I still need to use heapster, or if I can use metrics-server is very confusing. The wiki still states you have to use heapster?

[labria]

@chiefy this has been merged, but not yet released.

[leezout]

@labria Do we know the approximate release date for 2.0?

[Vrtak-CZ]

@leezout see https://github.com/kubernetes/dashboard/milestone/1

[ld-singh]

any idea on new release date for 2.0?

[xspeng]

How's this going?

[floreks]

Check the relases :)

[MarcusNoble]

Looks like there's a mistake in https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta1/aio/deploy/recommended.yaml, the deployment refers to kubernetes-dashboard-head while all other resources use kubernetes-dashboard.

I'm also having trouble running this on 1.13. Looks like the dashboard isn't finding the metrics scraper service so isn't starting.

[pratikvasa]

Ya same issue here..I tried deploying this and it worked. It is not on https though

[ld-singh]

Anyone faced issue mentioned in #4088 and fixed?

[lz006]

same issue here on 1.14

[starplanet]

Does this problem have been fixed on 1.14?

[maciaszczykm]

Metrics support is part of v2 beta. Beta is not part of K8s release, we have to make it final then we can update.

[nicklhy]

Same issue on kubernetes V1.15.2

[BskyRui]

Dashboard doesn't support metrics on Kubernetes V1.15.3 🙁

[floreks]

Any details about that? Version used? Configuration details? Without additional information, I am just assuming this is a configuration issue on your end.

Kubernets V1.15.3 & Dashboard v1.10.1, I installed metrics successful, After refresh the dashboard page, I can't see the CPU graph. I need to configure something?

[BouweCeunen]

I have this issue when there are 'completed' pods in my namespace. When I execute kubectl delete pods --field-selector=status.phase=Succeeded --all-namespaces, everything is ok.

[floreks]

@BskyRui what part of the sentence "Metrics support is part of v2 beta" is not clear? It will not work with v1. Also, there are still some issues related to the graphs itself: https://github.com/kubernetes/dashboard/milestone/1

[HelloMyDevWorld]

kubeadm v1.16.2 is there any idea how to run dashboard there ?

[oscarlofwenhamn]

@patsadow2 We've gotten the v2 beta dashboard running easily in our 1.16.2 cluster, using the manifest provided here.
