Pocket ViewPoint is a smartphone browser-based application. It has several components that can be
classified under the following groups:
 Web Server Engine
 Pocket ViewPoint Core Functions
 CPU, Process and Measure Metric Collectors
 Helper Objects and utilities
Web Server Engine
The Web Server is comprised of LISTAPP and PROCMAN. LISTAPP is the TCP/IP listener and
PROCMAN is the process manager. In STRTPVP, when you issue RUN PROCMAN, you are actually
starting the Web Server Engine. The Web Server accepts PARAM TCP-PROCESS and PARAM
LISTENER-PROCESS inputs because it needs to know which TCP process to use and what name
shall it assign to the listener process that is created. Each ASSIGN PROGCONFn corresponds to a
Pocket ViewPoint shell that the Web Server serves.
Pocket ViewPoint Core Functions
The Pocket ViewPoint core functions include CPU, process metrics reporting and Events display.
These functionalities are packaged within the POCKETVP object.
CPU and Process Metric Collectors
The performance function of Pocket ViewPoint needs CPU and Process metric information to display
CPU graphs and Process Busy tables. This information is collected and maintained by CSVRAPP,
CPROCAPP and PSVRAPP objects. The CSVRAPP collects CPU information. CPROCAPP analyzes
this information and does necessary calculations to generate CPU trend. PSVRAPP collects process
information.
