Scheduled Outages

Scheduled outages let you suppress notifications and pause status polling, threshold checking, and data collection during a specified time period. You might want to schedule an outage for any of the following reasons:

  • Updating components.

  • Performing scheduled reboots.

  • Planned decommissioning of nodes.

  • Preventing excessive notifications to on-call staff.

  • Completing scheduled infrastructure testing.

  • Other situations where known outages may be caused or thresholds may be reached

When you define a scheduled outage, you must set the following options:

  • Name.

  • Nodes to include.

  • Node interfaces to include.

  • Outage type (specific, daily, weekly, monthly).

  • Date and time for the outage.

  • Suppression settings (all notifications, status polling, threshold checking, data collection).

Scheduled outage parameters
Parameter Description

Node Labels

Nodes to include in the scheduled outage. At least one node is required to schedule an outage.

Outage Type

The outage’s recurrence schedule. An outage can be either a one-time occurrence (Specific) or a recurring event (Daily, Weekly, Monthly).

Interfaces

Interfaces to include in the scheduled outage. At least one interface is required to schedule an outage.

Applies To

Horizon services that will be suppressed during the outage (notifications, status polling, threshold checking, data collection). You can specify items for each service, or choose Select All.

During the scheduled outage, any nodes and interfaces that match the outage definition are suppressed.

Create a scheduled outage

You can create a scheduled outage in the Horizon web UI:

  1. Click the gear symbol at the top-right of the page.

  2. Under Service Monitoring, select Configure Scheduled Outages.

  3. Type a name for the outage in the New Name box and click the add symbol.

  4. Under Node Labels, select a node to include in the scheduled outage and click Add.

  5. Under Interfaces, select a node interface to include in the scheduled outage and click Add.

    • Alternatively, you can click Select All Nodes and Interfaces to include all nodes and interfaces in your monitored environment.

  6. Under Outage Type, select a recurrence schedule (Specific, Daily, Weekly, Monthly).

  7. Set a date and time for the outage. The available date and time settings depend on the recurrence schedule you choose:

    • Specific: Set a specific date and time period. This type of scheduled outage occurs only once during the specified period of time.

    • Daily: Set a time period during which a daily outage will occur.

    • Weekly: Set the day of the week and the time period during which a weekly outage will occur.

    • Monthly: Set the day of the month and the time period during which a monthly outage will occur.

  8. Click Add Outage.

  9. Under Applies To, select the functions that the outage will suppress:

    • Notifications: Suppress all or no notifications.

    • Status Polling: Include or exclude specific systems from status polling during the outage.

    • Threshold Checking: Include or exclude specific systems from threshold checking during the outage.

    • Data Collection: Include or exclude specific systems from data collection during the outage.

  10. Click Save.

Schedule an outage for a node

You can create a scheduled outage for a specific node in Horizon:

  1. Click Info  Nodes in the top menu bar.

  2. Click on the Node that needs a scheduled outage.

  3. Click Schedule Outage.

  4. Create an outage for the node [starting at step 5 since any outage created within a node will be named after the node]

You can also configure outages based on device dependencies with path outages.
