Overview

You inquire if it is possible to check which node the LGP is currently assigned to from the command or log.

Information

There is no command or parameter to check the LGP node. However, a way of checking could be as follows:
On the traffic node : cd /<directory used is logging profile>/available
Inside the "available" directory there will be directories of the "lgpnode" to which the .dat log file has been transferred and then marked as .DONE
This could give a view of which LGP node has received the logs from the traffic node.
