After setting up Datadog following the datadog / kubernetes tutorial, I went from one host (local one) to 7 and I don’t know why.
Since Datadog pricing is based on hosts, is it possible to reduce this number ?
Hello @mmc972 ,
When installing the datadog agent, it runs on every node of your cluster. As you have currently 3 nodes in your cluster, you should have at least 3 nodes in your datadog dashboard.
Duplicated hosts seem to be a known behavior on datadog side:
- It can happen either if you have manually added the hostname in the agent conf (AWS Integration Troubleshooting)
- or if the EC2
metadataendpoint is unreachable by the datadog agent (Duplicate hosts with Kubernetes on AWS (EC2 or EKS))
Did you add the host manually or block the metadata endpoint ?
