Abstract

Systems, methods, and device are provided for device monitoring. One method embodiment includes transmitting a network management message to a device. The method includes collecting response information from the device based on the network management message. The method further includes receiving unsolicited information from the device. The response information and the unsolicited information are analyzed according to a set of heuristics to provide a health measurement of the device.

messages reporting a non-functioning component on the device.

5. The station of claim 1, further including program instructions that execute to collectively analyze all of the information, both solicited and unsolicited, in order to formulate a health measurement for the device and for the network.

6. The station of claim 1, further including program instructions that execute to assign pre-selected weight values to the collected and received information as part of an applied heuristic and to use the weight values to provide the health measurement.

7. The station of claim 6, further including program instructions that execute to initiate network actions, based on the health measurement, to avoid potential issues with the device and the network.

8. The station of claim 1, further including program instruction that execute to implement different weight values to solicited and unsolicited information as parameters to the set of heuristics as suited to a particular type of network device.

9. The station of claim 1, further including program instruction that execute to implement different weight values to solicited and unsolicited information as parameters to the set of heuristics as suited to a particular type of network.

10. The station of claim 1, wherein the device and the station are connected over a local area network (LAN).

11. The station of claim 1, wherein the device and the station are connected over a wide area network (WAN).

12. A network management station, comprising:

a processor;

a memory coupled to the processor; and

program instructions provided to the memory and executable by the processor to;

poll a device, connected to the station over a network, with network management messages;

receive processor utilization, memory utilization, link up/down status, trap, buffer utilization, discard and error information in response to the polling and as unsolicited information initiated by and transmitted from the device; and

apply heuristics to the received information from the polling and unsolicited transmissions collectively to determine a health of the device.

13. The station of claim 12, further including program instructions which execute to display a visual indicator of the health of the device.

14. The station of claim 13, further including program instructions which execute to display additional detail report information upon a selection of the visual indicator.

15. The station of claim 12, further including program instructions that execute to register, as a parameter to the applied heuristics, that the data traffic through a port of the device is being under utilized.

16. The station of claim 15, further including program instructions that execute to register, as a parameter to the applied heuristics, that the data traffic through a port on another network device is overburdened.

17. The station of claim 16, further including program instructions that execute to initiate an action based on the determined health of device in order to avoid a problem on the device and the network.

18. A method for network and network device monitoring, comprising:

transmitting a network management message to a device;

collecting response information from the device based on the network management message;

receiving unsolicited information from the device; and

analyzing the response information and the unsolicited information according to a set of heuristics to provide a health measurement for the device.

19. The method of claim 18, wherein the method further includes transmitting an SNMP message to the device.
