Description Larry O'Leary 2012-10-24 19:32:29 EDT
+++ This bug was initially created as a clone of JBoss ON Bug #869834 +++

Description of problem:
After enabling Apache ResponseTime metrics by installing the Apache response time module (mod_rt.so) call time data is not collected and therefore, not displayed in the ON UI.

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

How reproducible:

Steps to Reproduce:
1. Install ON system
2. Install Apache ResponeTime module into Apache httpd[1]
3. Start Apache httpd server
4. Start ON system
5. Import httpd server into inventory
6. Enabled calltime metrics on the virtual host's monitoring > schedules page
7. Set the response time log file path and name under the virtual host's inventory > connection page
8. Generate some activity to the httpd server (http://localhost/)
9. Wait for the metric collection schedule interval to pass

[1]: https://access.redhat.com/knowledge/docs/en-US/JBoss_Operations_Network/3.1/html/Admin_Setting_up_Monitoring_Alerts_and_Operations/rt-configuration.html#Apache_Configuration

Actual results:
No calltime data is displayed on the Calltime page and the agent logs the following message when DEBUG is enabled:
    DEBUG [ResourceContainer.invoker.daemon-11] (org.rhq.plugins.apache.ApacheVirtualHostServiceComponent)- Failed to connect to SNMP agent at - aborting metric collection...

Expected results:
Calltime data should be collected.
SNMP is not needed.

Additional info:
This is occurring because ApacheVirtualHostServiceComponent.getValues(MeasurementReport report, Set<MeasurementScheduleRequest> schedules) assumes that it is only collecting metrics from SNMP. The following lines of code break calltime metrics for Apache:

        //bail out quickly if there's no SNMP support
        if (primaryIndex < 0)
        if (!snmpSession.ping()) {
            log.debug("Failed to connect to SNMP agent at " + snmpSession + " - aborting metric collection...");
