Module tail 

The last access-log lines in memory, and live followers of new ones, for the admin API (18.10.0). Off until enable: then each batch the access-log sink writes out (every 100 ms, off the request path) is also split into lines here.

Constants

CAPACITY

Lines kept for recent.

MAX_FOLLOWERS

Followers at once; more are refused.

MAX_LINE

A longer line is cut to this many bytes (on a character boundary).

Functions

enable

Start keeping lines (the admin listener does, at start).

follow

Add a follower: false when MAX_FOLLOWERS already follow.

recent

The last n lines, oldest first.
