SNA network monitoring NMI

z/OS® Communications Server VTAM® provides a single AF_UNIX socket interface for allowing network management applications to obtain the following types of data:

Enterprise Extender (EE) connection data
This data contains information about all EE connections or a desired set of EE connections as specified by the application using the local IP address or host name, the remote IP address or host name, or both.
Enterprise Extender summary data
This data contains information comprising a summary of EE activity for this host.
High Performance Routing (HPR) connection data
This data contains information about specific HPR connections Rapid Transport Protocol physical units (RTP PUs) as specified by the application using either 1) the RTP PU name, or 2) the RTP partner CP name with an optional APPN COS specification. These RTP PUs are not limited to those using EE connections.
Common Storage Manager (CSM) statistics
This data always contains CSM storage pool statistics and CSM summary information and can optionally contain CSM storage owner statistics.

A client network management application polls for information through specific requests using an AF_UNIX stream socket connection that uses VTAM as the server for that socket. The requested data is provided to the application directly using the AF_UNIX stream socket connection.
