Hi team! In light of discussions about ceilometer backends, we decided to test performance of different storage backends with collector and api services because these services depend on backends availability.
For the collector testing we are using not completely real data, we are generating looking like real samples with variable rate, sending them to the collector and metering the time of these messages processing. Testing result is the time between message receiving for recording message to db. For the api testing we are only comparing the time of requests to api with different backends. We have prepared a document with more detailed description of test plan and first results. This url: *https://docs.google.com/document/d/1ARpKiYW2WN94JloG0prNcLjMeom-ySVhe8fvjXG_uRU/edit?usp=sharing <https://docs.google.com/document/d/1ARpKiYW2WN94JloG0prNcLjMeom-ySVhe8fvjXG_uRU/edit?usp=sharing>* Please, add you cases and proposals for perfomance testing of collector and api to the document comments. Also you may use etherpad if it is more convenient. https://etherpad.openstack.org/p/performance_test_for_ceilometer_collector_and_api --- Best regards, Tyaptin Ilia, Intern Software Engineer.
