OpenStack infrastructure monitoring

Beyond the workloads running in OpenStack tenants, cloud operators must ensure that they have the necessary metrics to ensure OpenStack services’ availability, performance, and usage status. Monitoring data should involve mainly two different categories of the OpenStack infrastructure services, as follows:

• Cloud software: This includes OpenStack APIs, schedulers, databases, message busses, and load-balancing services.
• Under cloud: This includes running operating systems, storage, and network hardware.

In the following section, we will explore Prometheus, a well-integrated and adopted monitoring and alerting toolkit for large-scale deployment.
