Red Hat SummitChapter 1. Monitoring high availability services
Red Hat OpenStack Services on OpenShift (RHOSO) high availability (HA) uses Red Hat OpenShift Container Platform (RHOCP) operations to orchestrate failover and recovery deployment. When you plan your deployment, ensure that you review the considerations for different aspects of the environment such as hardware assignments and network configuration.
The following shared control plane services are required to implement HA:
- Galera
- RabbitMQ
- memcached
These services run as pods, and they are managed by Operators and monitored by RHOCP.
You can use the RHOCP client command line interface (oc) to interact with the platform and retrieve information about the status of the RHOSO control plane services. For example, you can use the oc to complete the following actions:
- Monitor the startup and the state and availability of the RHOSO HA services.
- Investigate the pods of the RHOSO HA services.
- Investigate the Operators of the RHOSO HA services.
- Describe the statefulset of the RHOSO HA services.
- Investigate the RHOSO HA services.
- Test the resilience of the RHOSO HA services.
