Abstract
Embodiments of the invention are directed to monitoring resources of a network processor to detect a condition of exhaustion in one or more of the resources over a predetermined time interval and to provide an indication of the condition. Some embodiments periodically sample various resources of a network processor and from the samples calculate utilization of the network processor's memory bus and core processor, and determine if an interworking FIFO packet queue error has occurred. Such information may help network operators and/or support engineers to quickly zero in on the root cause and take corrective actions for network failures which previously could have been attributed to many different causes and that would have required significant time and effort to troubleshoot.
