In daily work, some deadlock phenomena often occur and affect system performance.
Therefore, we need a way to monitor the deadlock in real time, once there is a deadlock, email us, and then the relevant people to solve.
Extended event is a lightweight tuning tool that takes up less resources, is highly configurable, and has high scalability.
So we chose to monitor the deadlock with ex

because smsman is a background service, it automatically discovers all the SMS devices connected to the computer during initialization, and periodically checks whether each SMS device is normal. When there is a problem with the device, smsman will promptly notify the user of a device error. You can use the interface to obtain all the SMS cat device management services, and then perform SMS and phone operations flexibly and freely. 2. interfaces provided by other middleware to users are single.
