Fixed In Version:	openstack-ceilometer-2014.2.3-4.el7ost	Doc Type:	Bug Fix
Doc Text:	Cause: Consequence: Fix: Previously, in some cases when using 'libvirt' driver, certain instances did not support usage metrics due to lack of balloon driver. This led to an unhandled exception that caused an Attribute error. This update adds checks in memory pollster to check if the object in 'None' and skip the pollster and log a message. As a result, unhandled exceptions are handled appropriately and logged. Result:	Story Points:	---

Comment 7 Yurii Prokulevych 2015-04-27 08:31:22 UTC

Verified using next steps:
1. Spawned 2 VMs
2. Got several polling cycles to get initial value for 'memory.usage' meter.
3. Stopped 1st VM.
4. While VMs was in 'SHUTOFF' state(~5 polling cycles) no traceback appeared in log.
5. After VM was enabled new meter's samples were gathered.
