Troubleshooting: Data Gathering Engine component does not remain in running state

PROBLEM:

Data Gathering Engine component does not remain in running state

CAUSE:

Not all network packets from DGE(x) reach the BVE server. The issue of dropped packets can be viewed by capturing a packet dump at BVE and DGE(x) end simultaneously and then open it in Wireshark tool.

Log entries similar to the below will also be observed in DGE/DGEx logs:

2016-12-22 10:35:56,993 j.ClientConnection[JMS Connection-com.zyrion.traverse.jms.ClientConnection]: \(ERROR\

RESOLUTION:

  • Review the network path to ensure that all network packets that are sent by DGE(x) are received by the BVE server.
