place release notes inline
Replace the instructions for querying for release notes with the results of a reno report because some of the broken release notes are on branches that have been closed and we have no way to edit them. Fix the markup by replacing LaTeX style quotes with RST quotes. Change-Id: I4a42c099280a8cd16e9efa3756058b1ed905926c Signed-off-by: Doug Hellmann <doug@doughellmann.com>

New Features
|
||||
------------
|
||||
|
||||
.. releasenotes/notes/batch-messaging-d126cc525879d58e.yaml @ c5895d2c6efc6676679e6973c06b85c0c3a10585
|
||||
|
||||
- Add support for batch processing of messages from queue. This will allow the collector and notification agent to grab multiple messages per thread to enable more efficient processing.
|
||||
|
||||
.. releasenotes/notes/compute-discovery-interval-d19f7c9036a8c186.yaml @ e6fa0a84d1f7a326881f3587718f1df743b8585f
|
||||
|
||||
- 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.
|
||||
|
||||

|
||||
|
||||
- Ceilometer alarms code is now fully removed from code base. Equivalent functionality is handled by Aodh.
|
||||
|
||||
.. releasenotes/notes/remove-cadf-http-f8449ced3d2a29d4.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc

|
||||
|
||||
- RPC collector support is dropped. The queue-based notifier publisher and collector was added as the recommended alternative as of Icehouse cycle.

|
||||
|
||||
.. releasenotes/notes/support-snmp-cpu-util-5c1c7afb713c1acd.yaml @ f24ea44401b8945c9cb8a34b2aedebba3c040691

|
||||
|
||||
|
||||
Known Issues
|
||||
------------
|
||||
|
||||
.. releasenotes/notes/support-lbaasv2-polling-c830dd49bcf25f64.yaml @ e6fa0a84d1f7a326881f3587718f1df743b8585f
|
||||
|
||||
- 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 Notes
|
||||
-------------
|
||||
|
||||
.. releasenotes/notes/always-requeue-7a2df9243987ab67.yaml @ 244439979fd28ecb0c76d132f0be784c988b54c8
|
||||
|
||||
- The options 'requeue_event_on_dispatcher_error' and 'requeue_sample_on_dispatcher_error' have been enabled and removed.
|
||||
|
||||
.. releasenotes/notes/batch-messaging-d126cc525879d58e.yaml @ c5895d2c6efc6676679e6973c06b85c0c3a10585
|
||||
|
||||
- batch_size and batch_timeout configuration options are added to both [notification] and [collector] sections of configuration. The batch_size controls the number of messages to grab before processing. Similarly, the batch_timeout defines the wait time before processing.
|
||||
|
||||
.. releasenotes/notes/cors-support-70c33ba1f6825a7b.yaml @ c5895d2c6efc6676679e6973c06b85c0c3a10585
|
||||
|
||||
- The api-paste.ini file can be modified to include or exclude the CORs middleware. Additional configurations can be made to middleware as well.
|
||||
|
||||
.. releasenotes/notes/gnocchi-client-42cd992075ee53ab.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- gnocchiclient library is now a requirement if using ceilometer+gnocchi.
|
||||
|
||||
.. releasenotes/notes/gnocchi-orchestration-3497c689268df0d1.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- gnocchi_resources.yaml in Ceilometer should be updated.
|
||||
|
||||
.. releasenotes/notes/improve-events-rbac-support-f216bd7f34b02032.yaml @ e6fa0a84d1f7a326881f3587718f1df743b8585f
|
||||
|
||||
- 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.
|
||||
|
||||
.. releasenotes/notes/index-events-mongodb-63cb04200b03a093.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- Run db-sync to add new indices.
|
||||
|
||||
.. releasenotes/notes/remove-cadf-http-f8449ced3d2a29d4.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- audit middleware in keystonemiddleware library should be used for similar support.
|
||||
|
||||
.. releasenotes/notes/remove-rpc-collector-d0d0a354140fd107.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- Pipeline.yaml files for agents should be updated to notifier:// or udp:// publishers. The rpc:// publisher is no longer supported.
|
||||
|
||||
.. releasenotes/notes/support-lbaasv2-polling-c830dd49bcf25f64.yaml @ e6fa0a84d1f7a326881f3587718f1df743b8585f
|
||||
|
||||
- By default, Ceilometer will poll the v2 API. To poll legacy v1 API, add neutron_lbaas_version=v1 option to configuration file.
|
||||
|
||||
|
||||
Critical Issues
|
||||
---------------
|
||||
|
||||
.. releasenotes/notes/always-requeue-7a2df9243987ab67.yaml @ 244439979fd28ecb0c76d132f0be784c988b54c8
|
||||
|
||||
- The previous configuration options default for 'requeue_sample_on_dispatcher_error' and 'requeue_event_on_dispatcher_error' allowed to lose data very easily: if the dispatcher failed to send data to the backend (e.g. Gnocchi is down), then the dispatcher raised and the data were lost forever. This was completely unacceptable, and nobody should be able to configure Ceilometer in that way."
|
||||
|
||||
.. releasenotes/notes/fix-agent-coordination-a7103a78fecaec24.yaml @ e84a10882a9b682ff41c84e8bf4ee2497e7e7a31
|
||||
|
||||
- [`bug 1533787 <https://bugs.launchpad.net/ceilometer/+bug/1533787>`_] Fix an issue where agents are not properly getting registered to group when multiple notification agents are deployed. This can result in bad transformation as the agents are not coordinated. It is still recommended to set heartbeat_timeout_threshold = 0 in [oslo_messaging_rabbit] section when deploying multiple agents.
|
||||
|
||||
.. releasenotes/notes/thread-safe-matching-4a635fc4965c5d4c.yaml @ f24ea44401b8945c9cb8a34b2aedebba3c040691
|
||||
|
||||
- [`bug 1519767 <https://bugs.launchpad.net/ceilometer/+bug/1519767>`_] fnmatch functionality in python <= 2.7.9 is not threadsafe. this issue and its potential race conditions are now patched.

|
||||
|
||||
- [`bug 1536338 <https://bugs.launchpad.net/ceilometer/+bug/1536338>`_] Patch was added to fix the broken floatingip pollster that polled data from nova api, but since the nova api filtered the data by tenant, ceilometer was not getting any data back. The fix changes the pollster to use the neutron api instead to get the floating ip info.
|
||||
|
||||
.. releasenotes/notes/fix-network-lb-bytes-sample-5dec2c6f3a8ae174.yaml @ 1689e7053f4e7587a2b836035cdfa4fda56667fc
|
||||
|
||||
- [`bug 1530793 <https://bugs.launchpad.net/ceilometer/+bug/1530793>`_] network.services.lb.incoming.bytes meter was previous set to incorrect type. It should be a gauge meter.

.. releasenotes/notes/refresh-legacy-cache-e4dbbd3e2eeca70b.yaml @ 66dd8ab65e2d9352de86e47056dea0b701e21a15
|
||||
|
||||
- A local cache is used when polling instance metrics to minimise calls Nova
|
||||
API. A new option is added `resource_cache_expiry` to configure a time to
|
||||
live for cache before it expires. This resolves issue where migrated
|
||||
instances are not removed from cache.

New Features
|
||||
------------
|
||||
|
||||
.. releasenotes/notes/http_proxy_to_wsgi_enabled-616fa123809e1600.yaml @ 032032642ad49e01d706f19f51d672fcff403442
|
||||
|
||||
- Ceilometer sets up the HTTPProxyToWSGI middleware in front of Ceilometer. The purpose of this middleware is to set up the request URL correctly in case there is a proxy (for instance, a loadbalancer such as HAProxy) in front of Ceilometer. So, for instance, when TLS connections are being terminated in the proxy, and one tries to get the versions from the / resource of Ceilometer, one will notice that the protocol is incorrect; It will show 'http' instead of 'https'. So this middleware handles such cases. Thus helping Keystone discovery work correctly. The HTTPProxyToWSGI is off by default and needs to be enabled via a configuration value.

Prelude
|
||||
-------
|
||||
|
||||
.. releasenotes/notes/rename-ceilometer-dbsync-eb7a1fa503085528.yaml @ 18c181f0b3ce07a0cd552a9060dd09a95cc26078
|
||||
|
||||
Ceilometer backends are no more only databases but also REST API like Gnocchi. So ceilometer-dbsync binary name doesn't make a lot of sense and have been renamed ceilometer-upgrade. The new binary handles database schema upgrade like ceilometer-dbsync does, but it also handle any changes needed in configured ceilometer backends like Gnocchi.

New Features
|
||||
------------
|
||||
|
||||
.. releasenotes/notes/add-magnum-event-4c75ed0bb268d19c.yaml @ cf3f7c992e0d29e06a7bff6c1df2f0144418d80f
|
||||
|
||||
- Added support for magnum bay CRUD events, event_type is 'magnum.bay.*'.
|
||||
|
||||
.. releasenotes/notes/http-dispatcher-verify-ssl-551d639f37849c6f.yaml @ 2fca7ebd7c6a4d29c8a320fffd035ed9814e8293
|
||||
|
||||
- In the [dispatcher_http] section of ceilometer.conf, verify_ssl can be set to True to use system-installed certificates (default value) or False to ignore certificate verification (use in development only!). verify_ssl can also be set to the location of a certificate file e.g. /some/path/cert.crt (use for self-signed certs) or to a directory of certificates. The value is passed as the 'verify' option to the underlying requests method, which is documented at http://docs.python-requests.org/en/master/user/advanced/#ssl-cert-verification
|
||||
|
||||
.. releasenotes/notes/memory-bandwidth-meter-f86cf01178573671.yaml @ ed7b6dbc952e49ca69de9a94a01398b106aece4b
|
||||
|
||||
- Add two new meters, including memory.bandwidth.total and memory.bandwidth.local, to get memory bandwidth statistics based on Intel CMT feature.
|
||||
|
||||
.. releasenotes/notes/perf-events-meter-b06c2a915c33bfaf.yaml @ aaedbbe0eb02ad1f86395a5a490495b64ce26777
|
||||
|
||||
- Add four new meters, including perf.cpu.cycles for the number of cpu cycles one instruction needs, perf.instructions for the count of instructions, perf.cache_references for the count of cache hits and cache_misses for the count of caches misses.
|
||||
|
||||
.. releasenotes/notes/support-meter-batch-recording-mongo-6c2bdf4fbb9764eb.yaml @ a2a04e5d234ba358c25d541f31f8ca1a61bfd5d8
|
||||
|
||||
- Add support of batch recording metering data to mongodb backend, since the pymongo support *insert_many* interface which can be used to batch record items, in "big-data" scenarios, this change can improve the performance of metering data recording.
|
||||
|
||||
.. releasenotes/notes/use-glance-v2-in-image-pollsters-137a315577d5dc4c.yaml @ f8933f4abda4ecfc07ee41f84fd5fd8f6667e95a
|
||||
|
||||
- Since the Glance v1 APIs won't be maintained any more, this change add the support of glance v2 in images pollsters.
|
||||
|
||||
|
||||
Upgrade Notes
|
||||
-------------
|
||||
|
||||
.. releasenotes/notes/always-requeue-7a2df9243987ab67.yaml @ 40684dafae76eab77b66bb1da7e143a3d7e2c9c8
|
||||
|
||||
- The options 'requeue_event_on_dispatcher_error' and 'requeue_sample_on_dispatcher_error' have been enabled and removed.
|
||||
|
||||
.. releasenotes/notes/single-thread-pipelines-f9e6ac4b062747fe.yaml @ 5750fddf288c749cacfc825753928f66e755758d
|
||||
|
||||
- Batching is enabled by default now when coordinated workers are enabled. Depending on load, it is recommended to scale out the number of `pipeline_processing_queues` to improve distribution. `batch_size` should also be configured accordingly.
|
||||
|
||||
.. releasenotes/notes/use-glance-v2-in-image-pollsters-137a315577d5dc4c.yaml @ f8933f4abda4ecfc07ee41f84fd5fd8f6667e95a
|
||||
|
||||
- The option 'glance_page_size' has been removed because it's not actually needed.
|
||||
|
||||
|
||||
Deprecation Notes
|
||||
-----------------
|
||||
|
||||
.. releasenotes/notes/deprecated_database_event_dispatcher_panko-607d558c86a90f17.yaml @ 3685dcf417543db0bb708b347e996d88385c8c5b
|
||||
|
||||
- The event database dispatcher is now deprecated. It has been moved to a new project, alongside the Ceilometer API for /v2/events, called Panko.
|
||||
|
||||
.. releasenotes/notes/kwapi_deprecated-c92b9e72c78365f0.yaml @ 2bb81d41f1c5086b68b1290362c72966c1e33702
|
||||
|
||||
- The Kwapi pollsters are deprecated and will be removed in the next major version of Ceilometer.
|
||||
|
||||
.. releasenotes/notes/rename-ceilometer-dbsync-eb7a1fa503085528.yaml @ 18c181f0b3ce07a0cd552a9060dd09a95cc26078
|
||||
|
||||
- For backward compatibility reason we temporary keep ceilometer-dbsync, at least for one major version to ensure deployer have time update their tooling.
|
||||
|
||||
|
||||
Critical Issues
|
||||
---------------
|
||||
|
||||
.. releasenotes/notes/always-requeue-7a2df9243987ab67.yaml @ 40684dafae76eab77b66bb1da7e143a3d7e2c9c8
|
||||
|
||||
- The previous configuration options default for 'requeue_sample_on_dispatcher_error' and 'requeue_event_on_dispatcher_error' allowed to lose data very easily: if the dispatcher failed to send data to the backend (e.g. Gnocchi is down), then the dispatcher raised and the data were lost forever. This was completely unacceptable, and nobody should be able to configure Ceilometer in that way."

||||

||||
|
||||
Bug Fixes
|
||||
---------
|
||||
|
||||
.. releasenotes/notes/add-db-legacy-clean-tool-7b3e3714f414c448.yaml @ 800034dc0bbb9502893dedd9bcde7c170780c375
|
||||
|
||||
- [`bug 1578128 <https://bugs.launchpad.net/ceilometer/+bug/1578128>`_] Add a tool that allow users to drop the legacy alarm and alarm_history tables.
|
||||
|
||||
.. releasenotes/notes/add-full-snmpv3-usm-support-ab540c902fa89b9d.yaml @ dc254e2f78a4bb42b0df6556df8347c7137ab5b2
|
||||
|
||||
- [`bug 1597618 <https://bugs.launchpad.net/ceilometer/+bug/1597618>`_] Add the full support of snmp v3 user security model.
|
||||
|
||||
.. releasenotes/notes/single-thread-pipelines-f9e6ac4b062747fe.yaml @ 5750fddf288c749cacfc825753928f66e755758d
|
||||
|
||||
- Fix to improve handling messages in environments heavily backed up. Previously, notification handlers greedily grabbed messages from queues which could cause ordering issues. A fix was applied to sequentially process messages in a single thread to prevent ordering issues.
|
||||
|
||||
.. releasenotes/notes/unify-timestamp-of-polled-data-fbfcff43cd2d04bc.yaml @ 8dd821a03dcff45258251bebfd2beb86c07d94f7
|
||||
|
||||
- [`bug 1491509 <https://bugs.launchpad.net/ceilometer/+bug/1491509>`_] Patch to unify timestamp in samples polled by pollsters. Set the time point polling starts as timestamp of samples, and drop timetamping in pollsters.
