This is Monitor Rolling Upgrade Process in MANO.
The MANO system plays a crucial role in the application upgrade process by sending a trigger to the application when the upgrade is about to take place so the applications have time to prepare necessary steps to ensure user experience remain unaffected. Monitoring during the upgrade process involves overseeing the performance and operational metrics of the application during the upgrade. Each application can be monitored by one or more KPIs, and if any of these metrics exceed their thresholds, it is considered a failure and will be handled by rollback.
The KPI metrics will be added at the start of the upgrade to track newly activated application and will be deleted at the end of the process regardless the result.
The monitoring system has the duty to collect, store and summary the data and firing alert about the threshold for MANO.
During the upgrade process, if the new instances fail the health check or any anomalies are detected by the monitoring system, the upgrade will be halted. |
