Plural clusters or occurrences of a pattern of event types are identified (). Based on configuration items relating to events associated with the event types, a correlation rule is created () to define a relationship between the event types.

Creating a correlation rule defining a relationship between event types

A first future time occurs sooner than a second future time. The first future time indicates when the first and second future times are to be evaluated. The second future time provides a boundary between schedules occurring sooner and schedules occurring later. A schedule is generated and added to a database stored in a non-volatile storage. The schedule is for executing, in relation to an incident, an incident-handling action corresponding to a condition matching the incident. The schedule has an execution time at which to execute the incident-handling action in relation to the incident. Where the execution time is sooner than the second future time, the schedule is added to a queue stored in a volatile memory. Upon a current time equaling the execution time, the schedule is removed from the queue and correspondingly executing the incident-handling action in relation to the incident.

Incident handling

A system is provided for dynamically identifying and correlating network domain events. The system includes a network domain and a plurality of managed objects in the network domain. A management server is in communication with the managed objects. The management server can receive domain events from at least one of the managed objects. A management module on the management server maintains a topology of managed objects in the network domain. A rule knowledge base is in communication with the management server. The rule knowledge base includes correlation rules for identifying and correlating domain events. A correlation module utilizes a processor to correlate the domain events with the topology using the correlation rules to identify an interaction between the managed objects and the domain events.

Domain event correlation

A method of granting a public-key certificate to a managed node in an IT network is provided. A request from the managed node to grant the certificate is received at a certification server. It is ascertained whether an initialization-to-request time interval between an initialization time of the managed node and a request time assigned to the request is within a maximum time interval for automatic certificate grant. The requested certificate is automatically granted if the initialization-to-request time interval is within the maximum time interval.
