摘要： The present application discloses a monitoring method and apparatus. A specific implementation of the method comprises: reading information about monitoring data acquisition methods of monitored objects, the monitoring data acquisition method comprising an active acquisition method and a passive acquisition method; executing following steps for each of the monitored objects having the active acquisition method as the monitoring data acquisition method: generating a monitoring data acquisition task of the monitored object; determining a monitoring data acquisition frequency of the monitored object; and adding the monitoring data acquisition task to to-be-executed monitoring data acquisition task sets in a defined period corresponding to the monitoring data acquisition frequency; executing, in successive defined periods, monitoring data acquisition tasks in the corresponding to-be-executed monitoring data acquisition task sets; and parsing acquired monitoring data of the monitored objects to generate a monitoring result. The implementation solves the problem of high system resource occupation and waste of system resources during the monitoring process.

摘要： The present application discloses a data transmission method and system. A specific embodiment of the method includes: receiving a data transmission-instruction by a data sender, wherein the data transmission-instruction includes a thematic name indicative of a type of to-be-transmitted data required by a data receiver; creating a shared memory segment corresponding to the thematic name. It makes possible for the data sender and the data receiver to run in a separate memory space. When data is needed to be transmitted, a corresponding shared memory segment may be created for data transmission in accordance with any transmitting requirement, and the shared memory segment may be released when the transmission is done or appears abnormal. On one hand, it reduces the redundant operations of the data transmission system during data transmission, and improves the data transmission performance; on the other hand, the data transmitting procedure between the data sender and the data receiver, and other operations executed by the data sender or the data receiver are independent of each other, which improves the stability of the data transmission system.

摘要： This disclosure discloses a method and apparatus for monitoring a message transmission frequency in a robot operating system. A specific implementation of the method includes: writing to-be-transmitted messages, into a pre-allocated memory; obtaining time points when the to-be-transmitted messages are written into the memory, and recording the time points in a preset time point list; determining a message transmission frequency within a preset time interval based on the time points in the time point list; and comparing the message transmission frequency with a preset message transmission frequency threshold, and generating monitoring information based on a comparing result. This implementation monitors the message transmission frequency of a process to thereby avoid information codes related to monitoring of each application from being added to the application so as to reduce the program debuging cost, and improve the monitoring efficiency.
