Keywords: minute, hour, weekday

InfraSonar provides dedicated keywords to make your alert expressions time-dependent. This is highly valuable for controlling when alerts are active.

Keyword Definitions:

• minute: A numeric (integer) value representing the current minute, ranging from 0 to 59.
• hour: A numeric (integer) value representing the current hour (in 24-hour format), ranging from 0 to 23.
• weekday: A string value representing the current day of the week (e.g., "Monday", "Tuesday", ..., "Sunday").

It is important to note that for all time-dependent keywords (minute, hour, weekday), the timezone of the container running the expression is used.

Example: Time-Based Alert Suppression

This example demonstrates how to suppress alerts for new errors outside of typical business hours (Monday-Friday, 8:00 AM - 5:30 PM).

case weekday in ['Saturday', 'Sunday']:
    return // Suppress all alerts on weekends

case hour < 8:
    return // Suppress all alerts before 8 AM

case hour > 17:
    case minute > 30:
        return // Suppress all alerts after 5:30 PM (17:30)

// If none of the above conditions are met
case item.error_count.diff() > 0:
    return WARNING, "Error(s) found on item: @item.name"

This setup allows for precise control over when alerts are active, reducing noise during non-operational hours.
