[Openstack] Nova-manage service list is not conveying loss of dependent services
Hi, Nova-manage service list is not conveying loss of dependent services Description: Though Rabbit MQ service is down, nova-compute service status is showing as alive, so VMs are regularly scheduled to this node and get stuck. Proposed Solution: Need to detect compute managers which have failed to contact the dependent service like RabitMQ, libvirt etc., after identifying the problem (after configurable number of retries) compute service should disable itself by logging proper reason into database and it should enable the itself once the detected problem resolves. With the proposed solution when the Rabbit MQ service is down service list shows as follows: nova-network nv-aw1st21-compute0001 nova disabled (unable to contact RabbitMQ) enabled 2013-01-02 05:33:00 To implement this approach need to introduce a new column "reason". Please comment on the proposed approach. Thanks, Kobagana Kumar DISCLAIMER == This e-mail may contain privileged and confidential information which is the property of Persistent Systems Ltd.

[Openstack] Incremental Backup of Instances
Hi All, I am working on Delta Changes of an instance. Can you please tell me The procedure to take Incremental Backups (Delta Changes) of VMs, instead of taking the snapshot of entire instance. And also please tell me how to apply those delta changes to instance.

[Openstack] [Metering] Implemented three methods in Ceilometer
Hi all, I have implemented three more classes in Ceilometer plug-in module. Added those classes in libvirt.py file in compute. The classes which I have added are counters to find out the following: 1. Number of CPUs used 2. Memory used 3. Maximum memory used I am also ready with test cases for those methods. Please let me know the procedure to contribute my code to ceilometer code base.

[Openstack] Clarification on Ceilometer Implementation
Hi all, I am trying to implement Agent module in Ceilometer. Regarding that I have few doubts: How Ceilometer capturing the usage details? As we are already know "nova simple usage" module captures the usage details of nova. It works at API level. But here in ceilometer we are trying to implement Agent module at compute level. For that how can we capture the usage details? What is the format of Plug- In? We can implement plug-in in various ways. We can use dictionary format, JSON format, etc. In which format Ceilometer implementing the plug - in and what are the attributes in that.
