That is unfortunately for access logs. For error logs you'd need
something like <if> and LogLevel but this would be rough for a
protocol-like filter since all of the early work would not have the
boosted trace level. Maybe a simple piped logger that discards traceN
messages w/o the interesting IP in them.
Probably something worth improving on.
