To define synchronization frequencies in Uptime Infrastructure Monitor, you input a string that represents the amount of time between actions. These units of time can be days, hours, minutes, seconds, or a combination. Frequency definitions are used when configuring user detail synchronization, when configuring Uptime Infrastructure Monitor to use an Active Directory or LDAP listing for user authentication and management. (See Changing How Users Are Authenticated for more information.)
When defining new, or editing existing, Maintenance Profiles and Monitoring Periods, you need to use precise definitions that Uptime Infrastructure Monitor can correctly interpret. Time period definitions use a controlled vocabulary that allow you to precisely define, combine, and exclude time periods. The following sections provide you with information on accurately defining time period definitions:
- Units of time that act as building blocks in definitions include times of day, days of the week, months, years, and exact dates.
- each day is separated by a comma (e.g., “ mon, tue, wed ”)
- spaces are optional (e.g., “ mon,tue,wed ”)
- Elements in the range must be separated by hyphens
- spaces are optional; the following examples are correct:
- 8:00 AM - 8:00 PM
- Fri - Mon
- ranges wrap around day and week boundaries:
- “ 10PM - 2AM ” is interpreted as 10:00 p.m to 11:59 p.m. on one day, and 12:00 a.m. to 2:00 a.m. the following calendar day
- “ Fri-Mon ” is interpreted as Friday through Saturday on one week, then Sunday through Monday the following week
- Uptime Infrastructure Monitor converts day ranges to lists (e.g., “ Fri-Mon ” becomes
“ Fri, Sat, Sun, Mon ”)
- day ranges and lists can be mixed; the following examples are correct:
- Fri - Sun, Mon
Note: Fixed dates that do not include a time range are interpreted to include the entire day (i.e., 12:00 a.m. through 11:59 p.m.), although this will not automatically appear in the defined time period.
Note: A fixed date without a time that is at the end of a date range is interpreted to include the first minute of the next day (e.g., Uptime Infrastructure Monitor converts “ From Oct 28, 2016 to Oct 29, 2016 ” into “ From Oct 28, 2016 12:00AM to Oct 30, 2016 12:00AM ”).
Note: Recurring days that do not include a time range are interpreted to include the entire day (i.e., 12:00 a.m. through 11:59 p.m.), although this will not automatically appear in the defined time period.
- fixed dates
- fixed date ranges
- weekly recurrences
- monthly recurrences
- monthly ordinal recurrences
- yearly recurrences
Combine basic expressions by writing each one on a new line in the Definition box when defining a Maintenance Profile or Monitoring Period. The following examples demonstrate combinations of different basic expressions used to define a maintenance window:
Note that when a time period consists of more than one component time period expression, a condition met within any of those component time periods applies to the entire time period. For example, if a Monitoring Period named “Open Hours” is defined as:
Time periods can be excluded from greater time period definitions by using the term “ exclude ” as a prefix to the exclusionary expression. The following examples demonstrate the use of exclusions in time periods:
