DisMan Schedule MIB

The DisMan working group also produced a mechanism for scheduling particular actions (a specified SET assignment) at given times. This requires that the agent was built with support for the disman/schedule module (which is included as part of the default build configuration for the most recent distribution).

There are three ways of specifying the scheduled action:

repeat FREQUENCY OID = VALUE

configures a SET assignment of the (integer) VALUE to the MIB instance OID, to be run every FREQUENCY seconds.

cron MINUTE HOUR DAY MONTH WEEKDAY OID = VALUE

configures a SET assignment of the (integer) VALUE to the MIB instance OID, to be run at the times specified by the fields MINUTE to WEEKDAY. These follow the same pattern as the equivalent crontab(5) fields.

These fields should be specified as a (comma-separated) list of numeric values. Named values for the MONTH and WEEKDAY fields are not supported, and neither are value ranges. A wildcard match can be specified as '*'.

The DAY field can also accept negative values, to indicate days counting backwards from the end of the month.

at MINUTE HOUR DAY MONTH WEEKDAY OID = VALUE

configures a one-shot SET assignment, to be run at the first matching time as specified by the fields MINUTE to WEEKDAY. The interpretation of these fields is exactly the same as for the cron directive.
