commit 3e03058e6b276b66affd1529d684882db3cc3a13 Author: Lukas Krejci <lkrejci@redhat.com> Date: Fri Nov 26 14:48:32 2010 +0100 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 build#1086 (Version: 4.0.0-SNAPSHOT Build Number: 7b2d9f6) Configured httpd.conf with ServerName with invalid hostname in the main server configuration and aslo inside VirtualHost definition. All the vhosts and the Main server are discovered. Marking as verified.
Bookkeeping - closing bug - fixed in recent release.
