Silencing Windows

Silencing Windows

Silencing Windows are 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). Silencing Windows are applied to resources and can be applied at either or both of the Host and Instance levels.

Silencing Windows can be created as one-time or recurring.

• The default time range for silencing windows is one month ago through one month in the future. This can be customized using the date picker in the top-right corner.
• The view can be further customized with Filters on Resources, State, and/or Tag.

Silencing Windows Card

This card displays the following information for all Silencing Windows meeting the currently configured filters.

Information is displayed in a table format with sortable columns, as follows:

• The State column displays whether the Silencing Window is Active, Recurring, set to run in the Future, or has Completed.

• The Ticket ID column references a planned Maintenance ticket, if any, for that Silencing Window.

• The Information column displays the timing of the Silencing Window.

• The Resources column displays the number of resources associated with the Silencing Window.

• The Comments column displays a description of or reason for the modification, and any other relevant information.

• Hover the cursor over the column headings to sort the list in ascending or descending order.

Existing Silencing Windows can be edited, extended, closed, or deleted, as follows:
