红帽全球峰会6.5. dynflow Tuning
dynflow 是工作流管理系统和任务编配器，它是一个 Satellite 插件，用于以特定顺序执行方式执行 Satellite 的不同任务。在 Satellite 上检查了大量客户端并运行许多任务时，Dynflow 可能会对添加的调优采取一些帮助，指定它可以启动多少个执行者。
有关与 Dynflow 相关的调整的更多信息，请参阅 https://satellite.example.com/foreman_tasks/sidekiq。
增加 Sidekiq worker 数量
Satellite 包含名为 dynflow-sidekiq 的 Dynflow 服务，用于执行由 Dynflow 调度的任务。sidekiq worker 可以分组到不同的队列中，以确保一种类型的许多任务不会阻止执行其他类型的任务。
红帽建议增加 sidekiq worker 的数量，以扩展 Foreman 任务以进行批量并发任务，例如，对于多个内容视图发布和提升、内容同步以及同步到 Capsule 服务器。有两个可用选项：
- 您可以增加 worker 使用的线程数量(worker 的并发)。这对因为线程并发实现而大于 5 的值有限制。
- 您可以增加 worker 数量，这是推荐的数量。
流程
将 worker 数量从一个 worker 增加到三个，而每个 worker 会保留五个线程/并发：
# satellite-installer --foreman-dynflow-worker-instances 3 # optionally, add --foreman-dynflow-worker-concurrency 5
可选：检查是否有三个 worker 服务：
# systemctl -a | grep dynflow-sidekiq@worker-[0-9] dynflow-sidekiq@worker-1.service loaded active running Foreman jobs daemon - worker-1 on sidekiq dynflow-sidekiq@worker-2.service loaded active running Foreman jobs daemon - worker-2 on sidekiq dynflow-sidekiq@worker-3.service loaded active running Foreman jobs daemon - worker-3 on sidekiq
