Silencing Windows

Silencing Windows

This card is used to create a time window for maintenance or planned outages by defining times when Alerts are temporarily suppressed or “silenced”. Alerts can occur both on the Host level (CPUs, Memory, etc.) and the Instance level (specific to a database). Separate Silencing Windows must be created on both the Host and Instance level to completely silence an Alert.
