Help to configure httpd.conf to create the mod_gzip Logfile

Help to configure httpd.conf to create the mod_gzip Logfile
Hello,

I have installed mod_gzip in my raq4 and it works ok.

I just can't configure httpd.conf to generate the log for mod_gzip.

I add in httpd.conf:

LogFormat "%h %l %u %t \"%V %r\" %>s %b mod_gzip: %{mod_gzip_result}n In:%{mod_gzip_input_size}n Out:%{mod_gzip_output_size}n:%{mod_gzip_compression_ratio}npct." common_with_mod_gzip_info2
CustomLog /var/log/httpd/mod_gzip_log common_with_mod_gzip_info2


But I always get the same error when I try to restart Apache:

Syntax error on line 149 of /etc/httpd/conf/httpd.conf:
Invalid command 'Out:%{mod_gzip_output_size}n:%{mod_gzip_compression_ratio}npct."', perhaps mis-spelled or defined by a module not included in the server configuration

What am I doing wrong?

where do I have exactly to place the "Logformat ...etc" in httpd.conf?

anybody had this problem?

Thanks.

I haven't tried mod_gzip. From your error log, it tells me you splitted the single line to two lines without slash.

Your line should be:

LogFormat "%h %....Out:%...ssion_ratio}npct." common_with_mod_gzip_info2

Note, I use .... just to shorten the line so you can see they are on the same line here.

You can also break that long line into two lines in httpd.conf like so:

LogFormat "%h %l %u %t \"%V %r\" %>s %b mod_gzip: %{mod_gzip_result}n In:%{mod_gzip_input_size}n \
Out:%{mod_gzip_output_size}n:%{mod_gzip_compression_ratio}npct." common_with_mod_gzip_info2

Thanks ... it worked :-)

I was pasting the single line in pico ant it splitted automatically in two lines...

Hi again,

Excuse me if I ask some basic questions but that's because I have just started with the Apache webserver and Linux.

Now that I have mod_gzip and mgstats working Ok on my box, I see that the mod_gzip_log is growing damn fast...

I would like to know how can I rotate this log at least twice a day.

Also I would like to know how can I just reset it.
What I do now is Stop Apache and reset it manually, then restart apache.

thanks for your help :-)

>> I would like to know how can I rotate this log at least twice a day

There are too many ways to do it. You can use newsyslog, check /etc/newsyslog.conf for details. Personally, I use my very own script. There are many people out there using cronolog -> http://www.ford-mason.co.uk/resources/cronolog/

Say cronolog, to rotate /var/log/httpd/access_log once a day:

LogFormat "%h %l %u %t \"%V %r\" %>s %b mod_gzip: %{mod_gzip_result}n In:%{mod_gzip_input_size}n \
Out:%{mod_gzip_output_size}n:%{mod_gzip_compression_ratio}npct."
TransferLog "|/usr/local/sbin/cronolog /var/log/httpd/%Y/%m/%d/access_log"

- The location becomes /var/log/httpd/2001/08/24/access_log
- cronolog runs as a standalone process in background so when it's time for rotation, it will restart httpd automatically

Hi,

Finally I used logrotate.
I placed a file called modgzip_rot in the /etc/logrotate.d

/var/log/httpd/mod_gzip.log {
missingok
compress
size 100M
}

When the mod_gzip.log reaches 100 mb it's rotated and reseted to 0 kb's but it does not log. It remains 0 kb's.

I delete mod_gzip.log restart apache and it is regenerated and logging again.

Can I do something to avoid stopping and restarting apache after the mod_gzip.log rotation?

No. You also can't manually rotating your mod_gzip.log this way:
cp -Rp mod_gzip.log /other/path/to/mod_gzip.log
cat /dev/null > mod_gzip.log

While Apache is running, if you alter the log file in any ways, Apache will no longer write to that file. You must HUP it.
