Claim 1:
2. The method according to claim 1, wherein the obtaining a device correlation based on a communication connection relationship between the device and another device, and correcting the basic health index of the device based on the device correlation to obtain a health index of the device comprises:
obtaining a data packet exchanged between the device and the another device;
adding the another device to a correlated device list of the device based on IP address and MAC address information of the data packet, wherein the device is also added to a correlated device list of the another device;
sorting a correlated device in the correlated device list of the device in ascending order based on a basic health index of the correlated device to obtain a sorted correlated device;
determining a correlation weight of the correlated device based on a quantity of correlated devices in the correlated device list; and
correcting the basic health index of the device based on the basic health index and the correlation weight of the sorted correlated device to obtain the health index of the device.
