Abstract: In a system monitoring method, a monitoring server extracts a plurality of features based on a plurality of data slices corresponding to a to-be-detected time period, where data of one of the data slices includes data in the to-be-detected time period. The monitoring server groups the plurality of features into a plurality of feature groups, and uses the plurality of feature groups as input data of an anomaly detection model. The monitoring server determines, based on a detection result of the anomaly detection model, whether the monitored indicator is abnormal.

Abstract: This application provides a communication method and apparatus. A terminal device receives a correspondence between reporting information and a to-be-activated TCI state, and a configured one-to-one correspondence between at least one TCI state and at least one first field, so that the terminal device can determine a to-be-activated TCI state and a first field corresponding to the TCI state. Therefore, on the basis of an existing mechanism of TCI state activation, based on reporting information of a terminal, the terminal device can autonomously activate a TCI state, and associate the TCI state with a corresponding field, so that signaling overheads and an indication delay are reduced, to improve performance of data transmission, and achieve good forward compatibility.

Abstract: A fingerprint unlocking method and a terminal are provided. The method may be applied to a terminal having an in-screen fingerprint detection function. When the terminal is in a screen-locked state, the terminal determines whether an operation of a user meets a preset condition. If the operation of the user meets the preset condition, a fingerprint recognition identifier is displayed on a touch display screen of the terminal. A display area of the fingerprint recognition identifier is an area in which fingerprint recognition can be performed. The method resolves a problem that the user cannot perform fingerprint unlocking because the user cannot see a position of a fingerprint detector.
