How to Configure a Global Blackout in Foglight (4213624)

A Global Blackout allows administrators to suppress alarms across the entire Foglight environment based on a configured schedule. This feature is typically used during planned maintenance windows, upgrades, migrations, or other activities that may generate expected alarms.

Administrators may need to temporarily suppress alarm generation and notifications for all monitored objects within Foglight. Rather than applying blackouts individually to agents or monitored hosts, a Global Blackout provides a centralized mechanism for controlling alarm suppression across the entire Foglight Management Server.

Foglight 6.3.0.5 and 7.1.4 introduced support for Global Blackouts through the system:globalblackout command available in the Foglight command-line utility (fglcmd).

Available Commands

• Enable a Global Blackout
  system:globalblackout -set -schedulename SCHEDULE_NAME
• Display the Current Global Blackout Configuration
  system:globalblackout -show
• Remove the Global Blackout
  system:globalblackout -clear

Example: Enable a Continuous Global Blackout

The following example applies the built-in Always schedule, which places the entire Foglight environment into a continuous blackout.

fglcmd -usr <username> -pwd <password> -cmd system:globalblackout -set -schedulename Always

Example output:

Global blackout schedule set to Always 30afa315-3131-48c2-b0e8-71fea187af4e

Verify the Current Global Blackout

fglcmd -usr <username> -pwd <password> -cmd system:globalblackout -show

Example output:

Global blackout schedule set to Always 30afa315-3131-48c2-b0e8-71fea187af4e

Remove the Global Blackout

fglcmd -usr <username> -pwd <password> -cmd system:globalblackout -clear

Example output:

Global blackout schedule is not set

View Available Schedules

To display all configured schedules, run:

fglcmd -usr <username> -pwd <password> -cmd schedule:list

The schedule name returned by this command can be specified using the -schedulename parameter when enabling a Global Blackout.

Foglight Cloud

Foglight Cloud provides API-based management of Global Blackouts. For assistance configuring Global Blackouts through the API, contact Quest Support.

• Global Blackouts are configured at the Foglight Management Server level.
• The blackout schedule remains active until it is cleared or the schedule expires.
• The built-in Always schedule can be used to immediately suppress alarms indefinitely.
• Use system:globalblackout -show to verify the current configuration.
• Use schedule:list to view all available schedules.
