Share Your ExperienceProduct Overview
The architecture of Tivoli NetView Performance Monitor (NPM) comprised several key components. The NPM Agent resided on the z/OS or z/VM system and collected performance data from VTAM and other SNA components. The Data Collector processed the collected data, performing calculations and aggregations.
The Reporting Facility generated reports based on the processed data. Communication between these components was primarily internal to the z/OS or z/VM environment, using proprietary protocols. Data was stored in VSAM datasets.
There was no external API. The network requirements included connectivity to VTAM and other SNA resources. The product's architecture was designed for the mainframe environment.
The lack of an open API and the proprietary data formats limited integration options. Users should consider solutions with more open architectures.
