You can set up one or more maintenance windows for your Keynote alarms. You can set up recurring maintenance windows or a one-time, absolute maintenance window when your site will be down and you want your alarms disabled. This is useful, for example, if your web server is regularly down for maintenance at a certain time each week, and you don’t want to be bothered with availability or performance alerts during this period.
No alarms are triggered during a maintenance window even if the performance or availability of a measurement meets alarm thresholds. However, data points are still gathered as the measurement itself is not suspended. If you run a scatter plot for a time period that includes a maintenance window, data points gathered during the window are displayed. During a maintenance window, an alarm is listed as temporarily disabled in the alarm Summary page.
You can create any number of maintenance periods. Each can be applied to any number of alarms. Each alarm can also have multiple maintenance periods assigned to it.
- Maintenance periods are most useful for recurring periods when you want alarms turned off temporarily.
- You can also set up one-time maintenance windows, or simply disable your alarms manually before and re-enable them afterwards.
