[users@httpd] httpd vhost centralized logging
Hi All,
I have running various web farms and I'm looking for better solution to
forward all vhost logs to the centralized syslog server. How do you guys
keep vhost logs? I have done googling this kind of setup but there is no
result.
I'm thinking to use logger tool for every httpd services running but it's
not an ideal because it takes more resources in server. Let say there are 50
vhost in a server, then 100 logger apps will be running because 2 logger per
vhost (ErrorLog & CustomLog).
Thanks.
Regards,
James

you can use one local facility and zillions of program names to distinguish
between different logs.

Have you looked at syslog-ng?
Also might want to take a look at loganalysis.org. They have some
resources which may (or may not) be of some help.

We wanted to use syslog too, but it's very rigid (only 8 localX facility
for custom logs) so we discarded this solution.
We heard of scribe, the logs aggregator Facebook uses; it seems very
flexible, and since FB is using it for his web servers, it's probably
doing its job quite well. Sitll, we didn't have time to pilot it.

For one single error log to wich all vhosts log, just place the ErrorLog
directive in the server config scope (outside of any VirtualHost container).
For multiple error logs, one for each vhost, place ErrorLog directives
in virtual host scope (inside VirtualHost containers).
The same goes for RewriteLog, ScriptLog, TransferLog and CustomLog.

Hi Jonas,
Thanks for your response. What is your configuration for ErrorLog on all
vhost?

James

Separate loggers for each main HTTP server is not the same as separate
loggers for each *virtual* host.
Set up the logging in the main httpd config and you can have all vhosts
use the same logger instance(s).
I currently have this in a reverse proxy with 65 vhosts:
CustomLog "|/usr/bin/logger -h 10.0.7.12 -t httpd -p local4.notice"
vhostcombinedsyslog
CustomLog "|/usr/bin/logger -h 10.0.7.12 -t httpd -p local4.notice"
vhostnumsyslognc
Those two lines results in a total of two logger apps running.
Regards
/Jonas

Don't get complicated through the various loggers available, simply use
logrotate the default linux application used to rotate the log files in
apache.
