Patent number: 8948010Abstract: The network device is described that comprises an allocator to adaptively allocate respective event message rate limits to client network devices that is in communication with an event-based system logging server to send event messages to the logging server for processing. The adaptively allocated event message rate limits are communicated to the client network devices so that limiting of a global rate of event messages received by the logging server comprises limiting the respective rates at which the client network devices can transmit event messages to the logging server. Measurement of respective event message rates comprises a count of event messages actually received by the logging server from the corresponding client device within a defined time window.Type: GrantFiled: August 29, 2012Date of Patent: February 3, 2015Assignee: Cisco Technology, Inc.Inventors: Steve Chen-Lin Chang, Shyyunn Sheran Lin, Junekang Yang, Jianbin Zhao, Ludwig Alexander Clemm

Patent number: 8868897Abstract: A method and apparatus for self-monitoring to identify an occurrence of a threshold and rebooting in response to the occurrence of the threshold is provided. In an embodiment, a data processing apparatus comprises one or more processors; logic coupled to the one or more processors and comprising one or more stored sequences of instructions which, when executed by one or more processors, cause the one or more processors to obtain a threshold associated with the apparatus; self-monitor the apparatus to identify an occurrence of the threshold; and self-reboot the apparatus responsive to the occurrence of the threshold.Type: GrantFiled: January 4, 2012Date of Patent: October 21, 2014Assignee: Cisco Technology, Inc.Inventors: Alexander Clemm, Junekang Yang, Steve Chen-Lin Chang, Jiabin Zhao, Shyyunn Sheran Lin

Patent number: 7752504Abstract: A network device and a method for monitoring operational messages is described. The method comprises monitoring an occurrence of an operational message of the network device, and storing dynamic context information at the time that the operational message occurred. The stored dynamic context information is then associated with the operational message. The operational message (e.g., a syslog message) may be stored together with the dynamic context information in a metalog memory and may comprise a snapshot of a procedure stack, the procedure stack including information indicative of a sequence of procedure invocations.Type: GrantFiled: May 31, 2007Date of Patent: July 6, 2010Assignee: Cisco Technology, Inc.Inventors: Steve Chen-Lin Chang, Ludwig Alexander Clemm, Junekang Yang, Jiabin Zhao, Shyyunn Sheran Lin

Publication number: 20090003345Abstract: There are provided a method, system, logic and network device to provide additional information and at least one recommended action relating to error information reported by a feature module of the network device. The method comprises generating a request that includes error information reported by a feature module of a network device, the error information including one or more runtime parameters associated with the network device. The method further comprises transmitting the generated request and receiving a response to the request including additional information and the at least one recommended action relating to the error information, the additional information and the at least one recommended action being based at least in part on the one or more runtime parameters.Type: ApplicationFiled: June 27, 2007Publication date: January 1, 2009Inventors: Steve Chen-Lin Chang, Ludwig Alexander Clemm, Jiabin Zhao, Junekang Yang, Shyyunn Sheran Lin
