We would like to see metrics to cumulate downtime in ArcGIS Monitor, such as for Portal, specific services, server roles, etc.
Currently, ArcGIS system managers have no way to easily see metrics on how many minutes parts of the system experienced downtime. Managers have to manually check the start and end time of downtimes.
This is to report numbers on system downtime to users and management, to support SLA compliance reporting and to quantify operational impact over time.
It should be possible to filter and select time and date ranges in ArcGIS Monitor and there should be metrics to present the total unavailability of a monitored component.
