Description Lukas Krejci 2010-11-23 21:02:25 UTC 
+++ This bug was initially created as a clone of Bug #656449 +++

Description of problem:
$SUBJECT is causing no Directory and IfModule resources to be discovered under the Main vhost.

Version-Release number of selected component (if applicable):
3.0.0

How reproducible:
always

Steps to Reproduce:
1. Have a apache configuration with some <Directory> and <IfModule> sections in the main server configuration (e.g. the default config after installing httpd on fedora for example)
2. have RHQ discover it and inventory it
3. Enable Augeas support in the connection properties of the apache server resource
4. run "discovery -f" on the agent command line
  
Actual results:
Failed discovery entries in the agent.log, no Directory or IfModule resources discovered under the Main vhost.

Expected results:
No exceptions in the agent.log, Directory and IfModule resource appear under the Main vhost.


Additional info:
This is specific to RHQ 3 (i.e. release-3.0.0 branch). RHQ 4 (master) shouldn't exhibit this issue.

    A cherry-pick and adaptation of the original fix ae99b5bc0bf42909308a9d1efc09cee77d06ffc1 in release-3.0.0 branch:
    
    a couple of robustness enhancements to the apache plugin:
    BZ 656449 - use the matching algorithm between SNMP values and augeas nodes also
      when matching the vhost node by resource key, because resource key
      in RHQ 3 is based on the SNMP value.
    BZ 652247 - Log the SNMP errors only on DEBUG level during discovery because SNMP isn't
      required for it to work.
    BZ 656476 - Do not fail the discovery if a non-existent directory is used in an Include directive
    BZ 652247, BZ 656491 - Do not choke on invalid/unresolvable hostnames in VirtualHost or ServerName directives

Verified on rhq-server-4.0.0-SNAPSHOT build#816.

Directory and IfModule resources appear under the Main vhost. No exceptions are
found in agent log. Please refer the screenshot.
