Mod_qos Directives Not Recognized

Earlier today I recompiled Apache to include mod_qos to deal with some traffic/load problems. Build and install went uneventful. mod_qos is showing up in Apache Status, build info, and adding /qos (not exact syntax) as describe in documentation indicates to mod_qos is running properly. However, I've been utterly unsuccessful in configuring any of the directives to configure mod_qos. After searching much of the web, it seemed that the appropriate way on cPanel is to use 'Apache Configuration' edit the includes and add directives to pre-main global include. However, anytime I add any mod_qos related directive it fails with a parser error that the directive is not recognized. I've tried multiple, including 'QS_LogOnly on' by itself. No luck. If I enclose the directives with the include file parses fine, but none of the directives appear to be executing. Clearly the resolves to false and simply skips them. I must be missing some obvious and stupid step. How can it be that mod_qos is running yet doesn't seem to be loaded or active from a configuration point of view? Here's one of the iterations of initial rules I tried (not the final set, I was just starting to get to test what might work). # Observe mode only for now QS_LogOnly on # Default Request Limit 50 per site, per IP 20, no keep alive after 10 QS_LocRequestLimitDefault 50 QS_SrvMaxConnPerIP 20 QS_SrvMaxConnClose 70 # limit number of logins to 5 every 10min QS_ClientEventBlockCount 20 SetEnvIf Request_URI /wp-login.php$ QS_Block=4 # Setup UA specific rules BrowserMatch "slurp" QS_Cond=spider BrowserMatch "googlebot" QS_Cond=spider QS_CondLocRequestLimitMatch "^.*$" 5 spider

  Tried to edit to include version info, but wouldn't let me. This is a Hostgator VPS, CentOS 6.6, WHM 11.50, Apache 2.2, mod_qos 11.5

  Do you see it here?
  httpd -l | grep -i qos
  Also you have to enable UniqueId in Exhaustive Options List, you can check if you have it from here:
  httpd -l | grep unique

  qos does not, but unique does: root@online [~]# httpd -l | grep -i qos root@online [~]# httpd -l | grep -i unique mod_unique_id.c root@online [~]#

  After more careful inspection of the compiled httpd.conf, it appears that the loadModule line is after the pre_main_global. So directives included in that pre_main_global conf wouldn't see the mod_qos module. Moving the directive into the pre_virtual_host_global include fixed it and it is now running. I thought I had tried that before, but maybe not. All good in the end. Thanks for the input and pointing me in the right direction.
