Description Marc Shirley 2011-04-20 23:36:22 UTC
Description of problem:
During discovery of httpd.exe, discovery appears to append the HTTPD_ROOT value to the apache installation directory.  For instance, if installing Apache to C:\Apache2.2, discovery will append the default value of HTTPD_ROOT, /apache, and look for the httpd.conf file at C:\Apache2.2\apache\conf\httpd.conf .

Version-Release number of selected component (if applicable):
JON 2.4.1

How reproducible:
Very

Steps to Reproduce:
1. Install Apache 2.2 in non-default directory such as C:\Apache2.2
2. Start Apache 2.2 as Windows service
3. Run discovery on agent
4. Check log for error.
  
Actual results:
Error "Apache configuration file C:\Apache2.2\apache\conf\httpd.conf was not found."

Expected results:
Agent should correctly discover httpd.conf and not write error to logs.

Additional info:
ERROR [ResourceDiscoveryComponent.invoker.daemon-1] (org.rhq.plugins.apache.ApacheServerDiscoveryComponent)- Discovery of Apache process [process: pid=[7788], name=[C:\Apache2.2\bin\httpd.exe], ppid=[696]] failed with an exception.

Comment 4 Sunil Kondkar 2011-11-18 14:14:24 UTC
Verified on build#93 (Version: 4.2.0.JON300-SNAPSHOT Build Number: 2619688)

Installed Apache 2.2 in non-default directory (C:\Apache2.2). Started Apache 2.2 as Windows service.

Agent correctly discovered the httpd.conf at "C:\Apache2.2\bin\httpd.exe". Please refer the attached screenshot. There is no apache discovery error in the logs.

Marking as verified.
