postfix and svlogd ?

postfix and svlogd ?

[Gilles]

Hello.

Is it possible to have postfix logging managed by svlogd?
[The postfix directory (in the debian package with sample
services) does not contain a log/run script.]

Thanks.
Gilles

It seems I didn't get any response to that one...
Doesn't anyone use postfix with runit?

Postfix uses syslog, but is there a way to make it work with
svlogd?
Or will I have to install socklog and set it up as a UNIX
log service?

Last time I looked I found that postfix works quite hard to make itself 
unsupervisable. I haven't seen any patches for it to make it better 
behaved, but I also haven't looked very hard.

This was on a page linked from the top page in a google search on "postfix
runit".

Thanks Mike.

Looks like the initscripts-ng-devel list is another good resource. See, 
e.g.:

http://www.mail-archive.com/initscripts-ng-devel@lists.alioth.debian.org/msg00015.html

Is there anything about logging on that page?

The question was how to make postfix provide its logging output
as input to svlogd (if it's at all possible).
[The intention is to avoid running syslogd.]

But am I seriously mistaken, or is it again some info about how
to run postfix supervised?  And not about how to grab postfix
log messages so as to be able to use "svlogd"?

The fact that several people seem to imply that it isn't trivial
(such as the need for a patch to be applied, as stated above) to
run postfix under runit make me wonder about the example script
provided by Gerrit Pape, copied here below:

---CUT---
#!/bin/sh
exec 1>&2

daemon_directory=/usr/lib/postfix \
command_directory=/usr/sbin \
config_directory=/etc/postfix \
queue_directory=/var/spool/postfix \
mail_owner=postfix \
setgid_group=postdrop \
  /etc/postfix/postfix-script check || exit 1

exec /usr/lib/postfix/master
---CUT---

[No mention of any caveat.]
So actually, is this sufficient or not to run postfix under
supervision???


Thanks for your advice,
Gilles

Looks like it should be, but might be overkill as well.  What we use
with Annvix (and which works for supervision, without patches):

[vdanen@build ~]$ cat
svn/packages/releases/1.2-RELEASE/postfix/SOURCES/postfix.run 
#!/bin/sh
# this was originally posted at http://mandree.home.pages.de/postfix/daemontools.html
# but doesn't seem to be there anymore... thanks google!

set -e

PATH="/sbin:/usr/sbin:/bin:/usr/bin"

# this runs postfix supervised

command_directory=`postconf -h command_directory`
daemon_directory=`$command_directory/postconf -h daemon_directory`

# kill postfix if running to ensure we run supervised
$daemon_directory/master -t || $command_directory/postfix stop >/dev/null 2>&1

# make consistency check
$command_directory/postfix check >/dev/console 2>&1

exec $daemon_directory/master >/dev/null 2>&1

Hi.

Eventually, to bring a conclusion to this thread:

I don't know.  But...

... I installed socklog, set up as a "unix" log server, and
it's all that's needed.

At least for the Debian package, postfix runs fine as-is.


Thanks for the answers I've received.

Well, the patch that I have indicated is the minimum of
the minimum--and good so!--in fact it touches nearly zero
of Postfix. (I would also NOT accept anything of the genre
that would go more in depth AND DOESN'T come with Wietse
Venema's green light.) 

Why does it need to be in svlogd per se?, use
socklog--from the SAME runit series (or *family*) and uses
the IDENTICAL style of config. files--I don't start any
log service for Postfix. 

Example from my /var/log/socklog/mail/...: 

...
2006-03-08_14:33:46.20193 mail.info: Mar  8 21:33:44
 postfix/postfix-script: starting the Postfix mail system
 (foreground)
2006-03-08_14:33:56.25236 mail.info: Mar  8 21:33:56
 postfix/master[156]: daemon started -- version
 2.3-20060202, configuration /etc/postfix
...
2006-03-08_22:32:05.18664 mail.info: Mar  9 05:32:05
 postfix/pickup[1005]: xxxxx: uid=yyyy from=<zzz>
... 

It doesn't solve 1-1 your requirements, but it's a
solution ... provided your #1 goal is to use Postfix a' la
runit (and mine it is).
