Question about qslog

[Adam V.]

Hello,

So I have been familiarizing myself with this great Apache module, and
have decided to branch out into using some of the tools that come
packaged with the module (specifically, qslog). However, for the life of
me I cannot seem to get this to function properly, no matter how I
configure it.

I have tried using the suggested options (within and without "IfModule
log_config_module" &/or "IfModule qos_module" wrappers) both from the
main site:

CustomLog "|/usr/local/bin/qslog -o logs/qos_log -x -f ISBTQkU" "%h %>s
%b %T %{mod_qos_ev}e %k %{mod_qos_user_id}e"

And from the man page:

CustomLog "|/usr/local/bin/qslog -f ISBTQ -x -o
/usr/local/apache/logs/qos_log" "%h %>s %b %T %{mod_qos_ev}e"

LogFormat "%t %h \"%r\" %>s %b \"%{User-Agent}i\" %T"
TransferLog "|/usr/local/bin/qslog -f ..IRSB.T -x -o
/usr/local/apache/logs/qos_log"

And nothing seems to work. The only output I am ever able to get logged
looks like this:

27.01.2014
15:09:00;r/s;0;req;0;b/s;0;esco;0;1xx;0;2xx;0;3xx;0;4xx;0;5xx;0;av;0;<1s;0;1s;0;2s;0;3s;0;4s;0;5s;0;>5s;0;ip;3;usr;1;qV;0;qS;0;qD;0;qK;0;qT;0;qL;0;qs;0;sl;0.07;

Which appears to simply be broken output, as it looks like it is simply
logging all possible options, with zero values. It also appears to
simply be logging these every minute, regardless of whether there is any
traffic.

I even tried just running the comman straight from the terminal session,
and generating some traffic for it to parse, and the output remained the
same.

Might I ask if I am doing something wrong in my configurations? Or
perhaps I simply misunderstand how this utility is meant to function?

Thanks in advance.

Yes, qslog writes one log line every minute (1440 lines per day) showing how many requests the server has processed during that time.

This allows you to create graphs

and allows you to calculate/define your mod_qos rules respectively.
