How random is Metron's Doppler selection?


Mike Heath
 

Metron's documentation [1] says "All Metron traffic is randomly distributed
across available Dopplers." How random is this? Based on observation, it
appears that logs for an individual application instance are consistently
sent to the same Doppler instance. The consistency aspect is very important
for us so that our Syslog forwarder can consolidate stack traces into a
single logging event.

How random is this distribution really for an application instance's logs?
