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
