[jira] [Created] (BROOKLYN-425) Rebinding to MachineEntity: fails
to reconnect sensor feeds
Aled Sage created BROOKLYN-425:
----------------------------------
Summary: Rebinding to MachineEntity: fails to reconnect sensor feeds
Key: BROOKLYN-425
URL: https://issues.apache.org/jira/browse/BROOKLYN-425
Project: Brooklyn
Issue Type: Bug
Affects Versions: 0.10.0
Reporter: Aled Sage
Priority: Minor
I deployed a MachineEntity to a jclouds location (in this case openstack), and then restarted AMP.
Looking in the log, I saw this exception:

The consequences of this (for {{MachineEntity}}) is that it didn't call {{AddMachineMetrics.createMachineMetricsFeed}}, which it should have done if the VM was linux. Sensors like load-average, cpu-usage, etc will therefore not be updated.
