New GKE cluster logging thousands of errors

Asked 2021-Mar-08 at 16:12

After creating a fresh new Kubernetes cluster in Google Kubernetes Engine I am seeing a lot of errors in Google Cloud logging related to the metrics agent.

I have had that problem with an existing cluster on version 1.18.x. Then I upgraded to 1.19.x after the suggestion that this would fix it. However, the problem persisted so I upgraded to 1.20.x and still no change.

Eventually I created a new cluster with the most recent Kubernetes version and still see hundreds of errors being logged immediately after:

I deployed a new app to GKE, I see the GKE dashboard has thousands of errors on gke-metrics-agent:

It uses a high resource.

I checked the logs, and I saw all errors related to Prometheus, but I didn't find a way to troubleshoot these errors:

cluster version: 1.18.12-gke.1206

What are these errors, and how I can fix it?

It looks like some GKE 1.18.12-gke-X versions have bug where gke-metrics-agent produces a lot of Warning messages.

There is already a Public Issue Tracker ticket for this bug. You can follow updates regarding this issue here. You can also use (+1) to indicate that you are affected by this bug.

Workaround of this issue is to use newer version - 1.18.14-gke.1200+

Vulnerabilities

No vulnerabilities reported

Install metrics-agent

You can download it from GitHub.
You can use metrics-agent like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the metrics-agent component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .

Support

As the agent works at the bytecode level, we support any language which runs on the JVM. Every language which compiles and runs on the JVM must obey by the bytecode rules. This simply means we need to understand the translation mechanisms of each language for the language level method name to the bytecode level. In Java this is usually 1:1 (excluding some generics fun). You can always examine the javap (the Java Disassembler) command to view the bytecode contents in a more Java centric way. As an example. Lets take the followin Scala class. If we run javap on this. You can do the same for Kotlin, Clojure and any other JVM language. Be aware that there may be some quirks in the naming translations and it may not always be as simple as shown above.
