[`bug 1550436 <https://bugs.launchpad.net/ceilometer/+bug/1550436>`_]
Cache json parsers when building parsing logic to handle event and
meter definitions. This will improve agent startup and setup time.
---
features:
- >
To minimise load on Nova API, an additional configuration option was added
to control discovery interval vs metric polling interval. If
resource_update_interval option is configured in compute section, the
compute agent will discover new instances based on defined interval. The
agent will continue to poll the discovered instances at the interval
defined by pipeline.

fixes:
- >
[`bug 1539163 <https://bugs.launchpad.net/ceilometer/+bug/1539163>`_]
Add ability to define whether to use first or last timestamps when
aggregating samples. This will allow more flexibility when chaining
transformers.
---
features:
- >
[`bug 1518338 <https://bugs.launchpad.net/ceilometer/+bug/1518338>`_]
Add support for storing SNMP metrics in Gnocchi.This functionality requires
Gnocchi v2.1.0 to be installed.
---
upgrade:
- >
To utilize the new policy support. The policy.json file
should be updated accordingly. The pre-existing policy.json
file will continue to function as it does if policy changes
are not required.
fixes:

[`bug 1504495 <https://bugs.launchpad.net/ceilometer/+bug/1504495>`_]
Configure ceilometer to handle policy.json rules when possible.
---
fixes:
- >
[`bug 1532661 <https://bugs.launchpad.net/ceilometer/+bug/1532661>`_]
Fix statistics query failures due to large numbers stored in MongoDB. Data
from MongoDB is returned as Int64 for big numbers when int and float types
are expected. The data is cast to appropriate type to handle large data.
---
fixes:
- >
[`bug 1388680 <https://bugs.launchpad.net/ceilometer/+bug/1388680>`_]
Suppose ability to query for None value when using SQL backend.
---
features:
- >
Support for polling Neutron's LBaaS v2 API was added as v1 API in Neutron
is deprecated. The same metrics are available between v1 and v2.
issues:
- >
Neutron API is not designed to be polled against. When polling against
Neutron is enabled, Ceilometer's polling agents may generage a significant
load against the Neutron API. It is recommended that a dedicated API be
enabled for polling while Neutron's API is improved to handle polling.
upgrade:
- >
By default, Ceilometer will poll the v2 API. To poll legacy v1 API,
add neutron_lbaas_version=v1 option to configuration file.
---
features:
- >
[`bug 1506959 <https://bugs.launchpad.net/ceilometer/+bug/1506959>`_]
Add support to query unique set of meter names rather than meters
associated with each resource. The list is available by adding unique=True
option to request.
