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
