Kubernetes logging - can see everything but logs?

mehdi_b — Wed, 07 Sep 2022 07:43:25 GMT

I am trialling the dynatrace solution.

I have installed the classic integration on my kubernetes cluster (hosted on AKS but using the k8s agent)

I seem to see metrics et al, excepts logs of my pods.

cf below to show that the stuff seems to run alright

I understand that for application instrumentation, I need to redeploy the pods.. which I did

As I said dynatrace seems to give the metrics fine and even the smartscape topology is building up nicely.. but I am desperate to see the logs produced by pods or from instrumented java applications.

Keen to hear if someone has pointers to share

Best regards

Mehdi

Hi mehdi_b,

I have just set up a logging for a springboot app in an onprem OP cluster. It works fine. Application log can be seen.

It is not clear for me what is your dynakube instumentation type? classicfullstack? or something else? As far as I know app only instrumentation id not support the log monitoring yet.

What was your log monitoring configuration steps? Have you already done these steps?

1. Logstorage configuration, DT server restart required at managed env, in saas I don not know.

2. Log monitoring v2 should be switched on.

3. Process or host level log source configuration (example):

Log monitoring documentation:

I hope it helps.

thank you very much @Mizső !

I didn't realise that by default kubernetes log monitoring isn't enabled by default.

Below doc clarifies this point
