1. A method for determining a root cause of event messages on a network, the method comprising: receiving a first plurality of event message from the network, the first event message being associated with a service path through the network and representative of a change in status in the network; analyzing parameters of the first event message to determine if a first event associated with the first event message correlates to a second event; examining a field of the first event message to determine if the field is set to one of label switch path (LSP) down, LSP reroute, and LSP up; if the first event associated with the first event message correlates to the second event, assigning an impact level to the correlation between the first event and the second event, wherein the impact level assigned is one of a plurality of primary impact levels or one of a plurality of secondary impact levels; and if the first event associated with the first event message does not correlate to the second event, storing the first event message as an uncorrelated event.
