The format of this expression is the policy expression language. Filter evaluation stops immediately when any error is detected without executing the policyAction.

This object lets the manager control the maximum amount of time that may pass before an element is re-checked. In other words, in any given interval of this duration, all elements must be re-checked.

This object lets the manager control the maximum amount of time that may pass before an element has the action run on it. In other words, in any given interval of this duration, all elements under control of this policy must have the action run on them. Note that it is an implementation-dependent matter as to how the policy agent schedules the policy action on various elements within this interval." ::= { pmPolicyEntry 6 } pmPolicyPrecedence OBJECT-TYPE SYNTAX Integer32 (0..65535) MAX-ACCESS read-create STATUS current DESCRIPTION "The order in which policies on the local system are evaluated. A policy with a higher precedence value will be evaluated after a policy with a lower precedence. For example, a policy with a precedence value of 999 will be evaluated after a policy with a precedence value of 998. These values must be unique on the local policy system that realizes this module. The value for a particular policy should be the same across an administrative domain, though that is not mandatory. When the local policy system performs the evaluation in the pmPolicyFilter for the policy identified by this row it will also read the pmTrackingElementToPolicyStatus object for each object returned as a result of the policy evaluation. If that object is set to modified(3), then the pmPolicyAction shall not be taken on that element. The value of precedence(4), of pmTrackingElementToPolicyStatus is an indication that when an evaluation was performed by another policy, the pmTrackingElementToPolicyStatus was found to have a value of on(1) and that policy had a higher precedence value than the policy that initially set the value of the pmTrackingElementToPolicyStatus to on(1). In this event, the pmTrackingElementToPolicyPrecedence object shall have the value of the pmPolicyIndex for the policy with the higher precedence value entered. If the policy identified by this row of the pmPolicyTable has a higher precedence value than the value found in pmTrackingElementToPolicyPrecedence then the pmPolicyAction should be performed on the element and the pmTrackingElementToPolicyPrecedence object updated with the value of the pmPolicyIndex for this policy. The only exception to these rules is when the policy that has the higher precedence value in not currently running, i.e., the schedule is off." ::= { pmPolicyEntry 7 } pmPolicyGroup OBJECT-TYPE SYNTAX SnmpAdminString MAX-ACCESS read-create STATUS current DESCRIPTION "An administratively assigned string that is used to group policies.
