Hi,

how can a BIND 9 operator detect an DNSTAP overload condition?

My understanding is that BIND 9 worker threads write DNSTAP information into a circular buffer in memory, which is that read by a different
thread to write out the data (to file or socket).

Is there any indication to the user (log message, marker in DNSTAP data) in the situation where BIND 9 receives more DNSTAP events than it could
write out, so that older events get overwritten in the buffer?

I've read dnstap.c and I could not find a hint, but I've could missed
it.

Greetings

Carsten
