Hi,
We are using haproxy 1.6 and a custom log format with built-in variables
like %HM, %HP, %HQ and %HV.
Is it possible to restrict or rewrite the length of certain variables?
Especially %HQ (request query) may become very long in our environment
which leads to haproxy cutting off the log at 1024 bytes I think. This
is problematic, because our log parser misses important information
then. We do not need the whole query string in the logs. The first few
bytes would be fine.
One possible workaround could be to move the %HQ to the end of the log
line. It gets automagically cut when it becomes too long, but the same
issue may happen with %HP (request path) then.
Unfortunately I didn't find anything in the docs and badly failed while
trying to output a variable that only contains the first few bytes of
some specific fields (especially "path" and "query").
Best regards
