Values.ScheduleSourceSpecifies when and how long an alarm mute rule is active. The schedule uses either a cron expression for recurring mute windows or an at expression for one-time mute windows. When the schedule activates, the mute rule mutes alarm actions for the specified duration.
type nonrec t = {expression : Expression.t;The schedule expression that defines when the mute rule activates. The expression must be between 1 and 256 characters in length. You can use one of two expression formats: Cron expressions - For recurring mute windows. Format: cron(Minutes Hours Day-of-month Month Day-of-week) Examples: cron(0 2 * * *) - Activates daily at 2:00 AM cron(0 2 * * SUN) - Activates every Sunday at 2:00 AM for weekly system maintenance cron(0 1 1 * *) - Activates on the first day of each month at 1:00 AM for monthly database maintenance cron(0 18 * * FRI) - Activates every Friday at 6:00 PM cron(0 23 * * *) - Activates every day at 11:00 PM during nightly backup operations The characters *, -, and , are supported in all fields. English names can be used for the month (JAN-DEC) and day of week (SUN-SAT) fields. At expressions - For one-time mute windows. Format: at(yyyy-MM-ddThh:mm) Examples: at(2024-05-10T14:00) - Activates once on May 10, 2024 at 2:00 PM during an active incident response session at(2024-12-23T00:00) - Activates once on December 23, 2024 at midnight during annual company shutdown
*)duration : Duration.t;The length of time that alarms remain muted when the schedule activates. The duration must be between 1 and 50 characters in length. Specify the duration using ISO 8601 duration format with a minimum of 1 minute (PT1M) and maximum of 15 days (P15D). Examples: PT4H - 4 hours for weekly system maintenance P2DT12H - 2 days and 12 hours for weekend muting from Friday 6:00 PM to Monday 6:00 AM PT6H - 6 hours for monthly database maintenance PT2H - 2 hours for nightly backup operations P7D - 7 days for annual company shutdown The duration begins when the schedule expression time is reached. For recurring schedules, the duration applies to each occurrence.
*)timezone : Timezone.t option;The time zone to use when evaluating the schedule expression. The time zone must be between 1 and 50 characters in length. Specify the time zone using standard timezone identifiers (for example, America/New_York, Europe/London, or Asia/Tokyo). If you don't specify a time zone, UTC is used by default. The time zone affects how cron and at expressions are interpreted, as well as start and expire dates you specify Examples: America/New_York - Eastern Time (US) America/Los_Angeles - Pacific Time (US) Europe/London - British Time Asia/Tokyo - Japan Standard Time UTC - Coordinated Universal Time
