Background technique

At present, the internal positioning problem of research and development generally uses the debug version of the program to eliminate the fault. The method of obtaining the message trace is generally to set a breakpoint under the program debugging tool gdb and then use the bt command to view the function call stack information, or set the target function layer by layer. Breakpoint, if the target function is interrupted, the function is executed, and vice versa.

However, the traffic is interrupted during the gdb debugging process; the version used in the live network release is generally the release version, and the non-gdb mode cannot be used for direct gdb debugging, and gdb attach pid cannot be used for debugging in the live network environment where traffic interruption is not allowed. Therefore, when the traffic is blocked or the business function is abnormal in the live network environment, it is impossible to use the existing technology to judge the function call process through which the message passes, and it is impossible to confirm which layer the message is discarded (layer 2: The physical link layer; the third layer: the transport layer; the fourth layer and above: the network layer), whether there is a problem with the receiving direction or the sending direction, etc.
