I have seen feature requests in the past that when haproxy reloads, to
pull the health status of the servers so that haproxy knows their state
without having to health check them. Willy has said he liked the idea
(http://marc.info/?l=haproxym=139064677914723). If this gets
implemented, it would probably be a minor detail to not only dump the
up/down state, but all stats.

Hi Andreas,
Its not like your question was wrong, but probably there is no
good/satisfying short answer to this, and it was overrun by other
mails...
As far as i know it is not possible to keep this kind information
persisted in haproxy itself when a config restart is needed.
The -sf only makes sure old connections will nicely be closed when
they are 'done'.
I have 'heard' of statistics gathering tools that use the haproxy unix
stats socket to query the stats and store the information in a
separate database that way you could get continued statistics after
the config is changed.. I don't have any examples on how to do this or
have a name of such a tool in mind though.. Though googling for
haproxy monitoring quickly shows some commercial tools that have
haproxy plugins and probably would provide answers to the questions
you have.
Maybe others on the list do use programs/scripts/tools to also keep
historical/cumulative data for haproxy and can share their experience
with it?

Hi all,
the list is normally really responsive. In this case nobody
gave an answer. So, I don't know whether my question was such a
stupid one that nobody wanted to answer.
So, I bring it up again in the hope someone is answering:
Is there a way to reload the configuration without loosing
current statistics? Or is this conceptually not possible?
Best regards
Andreas Mock

Betreff: Keeping statistics after a reload
Hi all,
is there a way to reload a haproxy config without resetting the
statistics shown on the stats page?
I used
haproxy -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid)
to make such a reload. But after that all statistics are reset.
Best regards
Andreas Mock
