Bug 1209558

Description of problem:
The RtFilter never load vHostMappingFile from absolute or relative path in EAP 6. 

Version-Release number of selected component (if applicable):
3.3.1

How reproducible:
Always

Steps to Reproduce:
1. Install and configure RtFilter in JBoss EAP 6 standalone server as per https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Operations_Network/3.3/html-single/Users_Guide/index.html#installing-rt-filters

2. Then Add following in web application web.xml :

<filter>
    <filter-name>RhqRtFilter</filter-name>
    <filter-class>org.rhq.helpers.rtfilter.filter.RtFilter</filter-class>
    <init-param>
        <param-name>vHostMappingFile</param-name>
        <param-value>/opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties</param-value>
    </init-param> 
</filter>

3. Create /opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties file with below configuration :

jon.localhost.com = testvirtualserver
test1.example.com = testvirtualserver

4. Restart the JBoss EAP 6 server to reload the new changes.


Actual results:

The RtFilter never load vHostMappingFile from absolute path /opt/jboss-eap/jboss-eap-6.2/standalone/configuration/ and throw below warning in EAP6 server.log:

22:36:33,806 WARN  [org.rhq.helpers.rtfilter.filter.RtFilter] (ServerService Thread Pool -- 51) Can't read vhost mappings from /opt/jboss-eap/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties

Expected results:
The RtFilter should load vHostMappingFile from absolute path /opt/jboss-eap/jboss-eap-6.2/standalone/configuration/ without throwing any warning.

Correction :

Actual results:
 
The RtFilter never load vHostMappingFile from absolute path
 /opt/jboss-eap-6.2/standalone/configuration/ and throw below
 warning in EAP6 server.log:
 
22:36:33,806 WARN  [org.rhq.helpers.rtfilter.filter.RtFilter] (ServerService
Thread Pool -- 51) Can't read vhost mappings from

Micke, would you mind to have a look? Thanks!

The configuration is incorrect, it should NOT be absolute path but instead only the configuration filename that would reside in the configuration/ directory. So in this case:

<param-value>vhost-mappings.properties</param-value>

The documentation could use some work to clarify this.

Tested on 3.3.0.GA Update 03 ( Build Number : 82ad0cc:a25836e )

Installed and configured RtFilter in JBoss EAP 6.2 standalone server by following the steps.

Changed <param-value> to "<param-value>vhost-mappings.properties</param-value>" in web.xml of attached helloworld.war 

Created /opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties file and deployed the helloworld.war to EAP6.2.

After restarting the JBoss EAP 6.2 server, the EAP6.2 server.log throws the below warning:

16:19:05,834 WARN  [org.rhq.helpers.rtfilter.filter.RtFilter] (ServerService Thread Pool -- 53) Can't read vhost mappings from vhost-mappings.properties.

Attaching the standalone.xml, helloworld.war and vhost-mappings.properties for reference.

Right, this feature has never worked in AS7 based applications (including any EAP6) - as the code has been done before the release of AS 5.0. I'm not sure it's even possible to support the documented way of doing things as the EAP6 class loader does not show these files.

Fixed in the master to use jboss.server.config.dir system property (to maintain current documented behaviour):

    [BZ 1209558] Read RtFilter files from jboss.server.config.dir system property directory

Available for test with 3.3.3 ER01 build: 
https://brewweb.devel.redhat.com/buildinfo?buildID=446732
 *Note: jon-server-patch-3.3.0.GA.zip maps to ER01 build of
 jon-server-3.3.0.GA-update-03.zip.

Verified on JBoss ON 3.3.3 ER01 build

Installed and configured RtFilter in JBoss EAP 6.2 standalone server by following the steps.

Created /opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties file and deployed the helloworld.war to EAP6.2.

When I had absolute path: <param-value>/opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties</param-value>

Restarting the JBoss EAP 6.2 server, the EAP6.2 server.log throws the below warning:

WARN  [org.rhq.helpers.rtfilter.filter.RtFilter] (ServerService Thread Pool -- 50) Can't find vhost mappings file from /opt/jboss-eap-6.2/standalone/configuration/opt/jboss-eap-6.2/standalone/configuration/vhost-mappings.properties

======================
Changed <param-value> to only the configuration filename as below:

<param-value>vhost-mappings.properties</param-value> in web.xml of helloworld.war 

There are no errors in EAP6.2 server.log

Also verified that the call time data is displayed:

Navigated to the webapp->web->Inventory->Connection Settings tab and edited Response Time Log File: /opt/jboss-eap-6.2/standalone/log/rt/helloworld1_rt.log

In Monitoring->Schedules tab enabled and set Response Time metric to 30 seconds

Verified after few minutes that the Monitoring->Calltime displayed the calltime data as attached for reference.

Marking this as verified as there are no errors when <param-value> is set only to the configuration file name.
