Subnets operations and L3-agent restart ======================================= In this scenario we restart all L3 agents while Neutron creates and deletes subnets. This report is generated on results collected by execution of the following Rally scenario: .. code-block:: yaml --- NeutronNetworks.create_and_delete_subnets: - args: network_create_args: {} subnet_create_args: {} subnet_cidr_start: "1.1.0.0/28" subnets_per_network: 2 runner: type: "constant_for_duration" duration: 120 concurrency: 4 context: users: tenants: 1 users_per_tenant: 1 quotas: neutron: network: -1 subnet: -1 hooks: - name: fault_injection args: action: restart neutron-l3-agent service trigger: name: event args: unit: iteration at: [100] Summary ------- No errors nor performance degradation observed. Details ------- This section contains individual data for particular scenario runs. Run #1 ^^^^^^ .. image:: plot_1.svg Baseline ~~~~~~~~ Baseline samples are collected before the start of fault injection. They are used to estimate service performance degradation after the fault. +-----------+-------------+-----------+-----------+---------------------+ | Samples | Median, s | Mean, s | Std dev | 95% percentile, s | +===========+=============+===========+===========+=====================+ | 85 | 2 | 2 | 0.16 | 2.4 | +-----------+-------------+-----------+-----------+---------------------+
