Using time ranges, a path can have a different alert profile at different times. For example, you might apply the ‘WAN’ profile during business hours to alert on data loss, latency, etc.; but after end-of-business, when performance is less critical, switch over to the basic ‘connectivity’ profile. Assuming a 9 to 5 workday your time ranges might look like this:
- Business hours
- M-F 9:00-17:00
- Sat-Sun 0:00-11:59
- Mon-Fri 0:00-8:59
- Mon-Fri 17:01-11:59
One continuous range, ‘always’, is pre-defined, and it’s applied when no other ranges are defined. To define other time ranges navigate to > Manage Time Ranges. Time ranges rely on the monitoring point time zone setting. If the timezone is incorrect, your alert conditions won’t be applied at the time you intended.
After you create your time ranges, you can pair them with alert profiles when you are creating or editing a path. Profile/time-range pairs are a per-path configuration. For example, ‘network health’ can be paired with the ‘business hours’ time range for one path, but with the ‘weekend’ range for another path.
If you delete a time range that is assigned to a path, the time range and its corresponding alert profile are removed from the path; if no other profile/time-ranges are assigned, then the last applied alert profile is paired with the default range ‘always’.
Overlapping time ranges
When applying multiple alert profiles, time ranges with the same frequency (e.g daily, weekly, etc.) and period (e.g 00:00-24:00) cannot overlap. When ranges with different frequencies have overlapping periods, an order of precedence determines which profile is applied: yearly time ranges supersede monthly, monthly supersedes weekly, weekly supersedes daily.
For example, two weekly ranges defined Friday 08:00-17:00 and Friday 16:00-18:00 cannot be applied to the same path. However, a monthly range, recurring on the 15th from 16:00-18:00, and a weekly range, Friday from 16:00-18:00, can be applied to the same path; if the 15th day of the month is ever a Friday, the monthly range is applied.
‘Always’ and ‘Daily’ are considered overlapping ‘Always’ and ‘Daily’ are considered overlapping and so they cannot be applied concurrently.
