This is likely a result of #2274

We'll use agent-{START_TIME}-{IP}.log for agent log names.

"agent" is added to distinguish agent from island logs.

Having the start time in the log could be useful during debugging. It will also allow log files to be sorted by name and appear in chronological order.

The IP is enough to uniquely identify machines for our test suite.
