which logger to enable for investigating Master/Slave communication

[Mohammed, Ashfaque]

Hi,

For Jenkins version 1.458, for Maven builds we are noticing sometimes even 
after the build is done the master is waiting for a long time to finish. So 
need to investigate whether master is waiting for the slave is slow to respond.

Would appreciate if someone can point the correct logger(s) to enable for 
debugging this.

Thanks.
Ash.
