enhancements for StackLight:
To obtain the enhancements, follow the steps described in
Apply maintenance updates.
Authentication for Prometheus and Alertmanager
Implemented authentication for Prometheus and Alertmanager web UIs through the
proxy nodes that are available if external access to cloud resources is enabled
in your OpenStack deployment.
OpenStack tenant monitoring
Enhanced OpenStack tenant monitoring by improving the Grafana dashboards:
- Improved the Ceph pools overview dashboard to display the read
and write IOPS and throughput per pool as well as sort the pools by top 5.
- Added the Nova - users and Nova - tenants dashboards
and improved the Nova - instances dashboard to display
comprehensive information about the usage and allocation of CPU, RAM, disk
throughput, IOPS, and space by file, network, and block devices, as well as
the information about the network throughput. Added the capability to sort
these metrics by top users, tenants, and instances.
- Improved the Nova - utilization dashboard.
- Removed the Openstack - Tenants dashboard in favor of the
informative Nova - users and Nova - tenants
dashboards.
Prometeus alerts enhancement
Enhanced the Prometheus alerts by adding the
PrometheusRuleEvaluationsFailed alert that raises in case of evaluation
failures of the Promethues recording rules.
