Monitoring Ingress HTTP traffic from all namespaces.

I found the following item on the Netdata documentation page.

After that I tried to list this plugin in my Values.yaml and start a helm upgrade.

helm upgrade -f values.yaml netdata netdata/netdata,
             --namespace monitoring,
             --set parent.nodeSelector."beta\.kubernetes\.io/os"=linux,
             --set child.nodeSelector."beta\.kubernetes\.io/os"=linux,
             --set parent.database.volumesize=4Gi,
             --set-file sd.child.configmap.from.value=./child.yml

Unfortunately without success. Do you have any suggestions how to achieve this goal ?

Eventuel also interesting to know. My service discovery looks like this.

Possibly also interesting to know. My service discovery looks like this.

Thanks in advance for any help!

The configuration looks alright to me.

Can you please send us the error.log that you should find in /var/log/netdata of the child pod that runs Netdata?

Do you have any input @ilyam8 regarding the k8s setup?

Thanks for approving my account and for the quick feedback.

it’s not like i don’t see any info in netdata.
But not the one I need. Effectively I only need the HTTP requests that go through the ingress

If more information is needed I am at your disposal.

Hi @chefcook, sorry for the delay in getting back to you.

Gave a short answer in Monitoring Ingress HTTP traffic from all namespaces. · Issue #221 · netdata/helmchart · GitHub

TL;DR

Unfortunately, it is not possible atm. Fortunately, we plan to have that fixed this quarter :smiley:


If you have any other questions or wants me to provide any details - I’m happy to answer.
