ABSTRACT:
A method in a data processing system for monitoring for errors on a network. Responsive to detecting a change in a state of the network, determine whether the change in state is a loss of a communications link to a remote data processing system. If the change in state is a loss of the communications link, determine whether the communications link was established for at least a first period of time to be considered an acceptable connection to the remote data processing system; and create a new serviceable event, if a second period of time passes without reestablishing the communications link to the selected data processing system. Repeat occurrences of identical outages are tracked and multiple detected instances of an outage for different partitions are counted as a single failure in the examples.
