Per comment-3

Tested on Version 5.9.0.10.20171121225911_a2209d2 

Observed that reports are generated only when Middleware provider does not have any EAP server in relationship.
When an EAP standalone server is installed and associated with Middleware Provider, the report is not generated. It shows error status in UI and show below error in evm.log:

[----] E, [2017-11-27T05:17:22.349203 #13225:1155134] ERROR -- : [NoMethodError]: undefined method `[]' for nil:NilClass  Method:[block in method_missing]
[----] E, [2017-11-27T05:17:22.349512 #13225:1155134] ERROR -- : /var/www/miq/vmdb/app/models/mixins/live_metrics_mixin.rb:44:in `included_children'
/opt/rh/cfme-gemset/bundler/gems/manageiq-providers-hawkular-83d9f0e5e915/app/models/manageiq/providers/hawkular/middleware_manager/live_metrics_capture.rb:12:in `initialize'

Steps to reproduce:

1. Login to cfme and add a middleware provider (No standalone EAP is associated)
2. Navigate to cloud Intel >> Reports
3. Click Reports >> Performance by Asset Type >> Middleware servers
4. Click on any link for example 'JVM Garbage Collection - daily averages for last week'
5. Click on 'Queue' button at the top left on the screen to generate the report
6. Observe that the report is generated successfully ( Screenshot attached )

7. Now Install EAP standalone server (Associate EAP server with middleware provider with hawkular URL parameter)
8. Refresh the middleware provider from middleware provider summary->Configuration>Refresh item and relationships
9. Verify that the middleware provider summary shows the EAP standalone server in 'Relationships' section.
10. Navigate to Reports >> Performance by Asset Type >> Middleware servers
11. Click on any link to generate the report.
12. The report shows status 'Error' in UI and evm.log shows errors
( Screenshot and evm.log is attached )
