Hi, today in SWO, we can have a node that is "managed", "unmanaged" or "alert muted".
When the node is "managed" all is working as expected.
When the node is "alert muted" the node is managed (all polling done) but not alert is triggered, that's fine too.
When the node is "unmanaged", the polling is stopped, so there is no impact of a down node for maintenance on the availability calculation.
We propose to have another management mode where the node is still "managed", the polling continues and the alerts are raised BUT without availability calculation, or in other words the down status of the node does not impact the availability.
Why ? As a telecom operator, when we do fiber maintenance, we need to be able to verify the good restoration of the fiber link by checking a node (typically a WAN router) that is behind the fiber. When we set the node "unmanaged" we are not able to do this. But if we let the node "managed", then the availability is impacted and we have penalties (we serve public services).
This in-between management node is e.g. available in free monitoring software like Zabbix if inspiration is needed.
Thanks
