Memory and CPU usage of managed service for apache kafka

[RuiSMagalhaes]

Hi,

We are running a GCP Managed Kafka cluster in region europe-west2.

The cluster is active and processing traffic — we can see metrics such as Bytes_in_countand Bytes_out_count working correctly.

However, CPU and memory utilization metrics such as managedkafka.googleapis.com/cpu/usage and .../memory/usage are not available in Metrics Explorer.

Only cpu.limit and memory.limit are exposed.

I can see dashboards with cpu and memory usage at 0:

Is there anything we need to enable to receive those metrics ?
Is this expected or is this a possible issue in metric export ?

Thanks!

Hi @RuiSMagalhaes ,

Welcome to Google Cloud Community!

Here are some workaround that may help along with relevant documentation:

1. Check Service Account Permissions
Managed services usually operate with a Google-managed service account that has the necessary permissions to write metrics.

• The service agent for Managed Kafka typically has a role like roles/managedkafka.serviceAgent.
• You can find service agents in IAM by enabling “Include Google-provided role grants”. The service agent will be in the format service-<PROJECT_NUMBER>@gcp-sa-managedkafka.iam.gserviceaccount.com.

2. Check GCP Status Dashboard

• Go to the Google Cloud Status Dashboard, there might be regional issues affecting specific services or Cloud Monitoring.

Check for any ongoing incidents related to:

• Cloud Monitoring
• Managed Service for Apache Kafka
• Specifically in the europe-west2 region.

If Metrics Remain Unavailable/Zero for an active cluster, please reach out to our Google Cloud Support.
