Monitoring overview

You can monitor the health of your cluster and virtual machines (VMs) with the following tools:

OKD cluster checkup framework

Run automated tests on your cluster with the OKD cluster checkup framework to check the following conditions:

  • Network connectivity and latency between two VMs attached to a secondary network interface

  • VM running a Data Plane Development Kit (DPDK) workload with zero packet loss

The OKD cluster checkup framework is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

Prometheus queries for virtual resources

Query vCPU, network, storage, and guest memory swapping usage and live migration progress.

VM custom metrics

Configure the node-exporter service to expose internal VM metrics and processes.

VM health checks

Configure readiness, liveness, and guest agent ping probes and a watchdog for VMs.

The guest agent ping probe is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
