DHCP server is too chatty
The DHCP server dominates almost 90% of our hosts' syslogs:
And it's relatively useless spew, too:
Oct 16 06:52:49 aperture-science python: Get DHCPDISCOVER packet from ff:12:34:56:78:9a
Oct 16 06:52:49 aperture-science python: dhcp_backend : Discover
Oct 16 06:52:49 aperture-science python: dhcp_backend : Discover result = 188.8.131.52
Particularly useless, because most of the traffic is from our monitoring service, which sends 2 DHCPDISCOVERs every 5 minutes.
Currently all of our syslog messages are at level DEBUG or INFO. Both of those seem like they should be filtered out for a production service. If there's anything that matters, it should be logged at a higher priority level, and we should filter out the spew.
