The real-time statistics service acquires statistics for the entire system, for each server, and for each service. By outputting the acquired real-time statistics to the standard output or log files, you can check the operating status of the OpenTP1 system in real time, and can perform system operation management and error recovery more quickly.

This subsection provides an overview of the real-time statistics service. For details about operation using the real-time statistics service and the real-time statistics that can be acquired, see the manual OpenTP1 Operation.

The real-time statistics service uses the following UAPs:

RTSSUP

RTSSUP is the UAP to be activated when the real-time statistics service is used. RTSSUP can acquire and output real-time statistics.

RTSSPP

RTSSPP is the UAP to be activated when the extended facility of the real-time statistics service is used. The extended facility allows the user to change the settings for the information to be acquired while the real-time statistics service is running.

The following figure shows an overview of the real-time statistics service.

Figure 3-76 Overview of the real-time statistics service

The functionality of the real-time statistics service is described below. The paragraph numbers correspond to the numbers in the figure above.

1. The predefined real-time statistics items are acquired for the entire system, for each server, and for each service.
   Acquired real-time statistics are stored in the shared memory for the RTS service. For details about the shared memory used by the real-time statistics service, see 7.2.2(5) Shared memory used by real-time statistics service.
   The execution time of a specific section in a UAP can also be acquired as real-time statistics. For details about acquiring real-time statistics for a specific section in a UAP, see the OpenTP1 Programming Guide.
   
2. The real-time statistics stored in the shared memory for the RTS service are output.
   
   • The real-time statistics can be output to the standard output in real time.
   • The real-time statistics can be output to RTS log files.
   • The real-time statistics output to RTS log files can be edited and the editing results can be output as a CSV-format file.
3. The settings for the information to be acquired can be changed while the real-time statistics service is running.
