Getting started

This topic provides the overview of MainView for IP. It also describes the features and functions provided by MainView for IP that enable monitoring and management of TCP/IP stacks through customizable views.


MainView for IP provides utilities that enable you to monitor IBM z/OS mission-critical application performance. 

MainView for IP collects data from the Transmission Control Protocol/Internet Protocol (TCP/IP) stack and displays it through the MainView console as configurable views. You can monitor applications by job name, IP address, and port, and analyze which enterprise resources have priority access to critical data. You can also configure data collection in MainView for IP to allow filtering, which enables you to view this information (but not to change it).

Features and functions

The following table describes the monitoring and management features and the functions that are available in MainView for IP:




Initiates specific actions in a view, such as dropping a connection, pinging a device, or performing a traceroute.


Displays information about the availability and activity of application and stack connections.

Availability monitoring

Provides a single view from which you can monitor critical resources, such as applications, devices, links, and other resources.

Availability ping

Allows you to ping an IP network device automatically to determine its availability and provide device response times.


Displays configuration information by TCP, UDP, IP, SMF, and port.


Displays information about the devices that are connected to an application by domain name, IP address, and remote port number.


Displays information about a ping or a traceroute that you requested; performs packet tracing and socket tracing.

Dynamic VIPA

Displays information about Dynamic Virtual IP Addresses (DVIPA).

Enterprise extender

Displays information for Enterprise Extenders (EEs) shipped through the UDP protocol and information for Rapid Transfer Protocol (RTP) pipes that are used by Enterprise Extenders.

FTP Server

Displays File Transfer Protocol (FTP) Server statistics and configuration information.


Displays detailed views for applications that use hipersockets, such as devices, links, routes, sessions, and channel data.

Historical data

Displays information about previous performance (to compare with current performance).


Displays information about network devices, network links, and Open Systems Adapter (OSA) cards.


Displays IP addresses along 16-bit boundaries, with each 16-bit block converted to a 4-digit hexadecimal number separated by colons.

An IP address is 128 bits or 16 bytes long. In contrast to IPv6, IPv4 displays IP addresses in dotted decimal format. The IPv6 feature is available in every view that contains an IP address field.

IP pacing

Delays (or 'paces') outbound data from any TCP/IP application to provide more processing time to business-critical applications and displays information about applications that have been paced.


Displays IP security and defensive filtering configuration information for the TCP/IP stack.

Name Resolver

Displays the Name Resolver configuration information.

Open Systems Adapter

Gathers data about Open Systems Adapter (OSA) devices.

You can view OSA configuration information, utilization statistics, network device details, network link details, and ethernet-like statistics.

Packet and socket tracing

Provides sophisticated packet and socket tracing capabilities that can be dynamically started and stopped.

You can filter by protocol type, IP address, source port, and destination port. You can view packet header information in both a formatted and unformatted display. You can also view a subset of the actual packet data in hexadecimal dump format.

Routes and OSPF

Provides information about all routes as well as statistics and parameters related to OSPF.

Shared Memory Communications

Displays configuration and statistics for Shared Memory Communications.

SNMP data collection

Displays performance information about TCP, UDP, IP, system, interface router, OSPF, CISCO router, and network routes for every IP node that you specify.


Displays information about the Intrusion Detection Services (IDS), which enables detecting attacks and applying defensive mechanisms on the z/OS server.

Service levels

Displays information about application availability and your web servers to help ensure that you are meeting your service level agreements.


Displays statistics from the following areas about buffer pools and storage usage:

  • Communications storage manager (CSM)

  • Virtual Telecommunications Access Method (VTAM)

  • TCP/IP private and common storage

  • Common storage area (CSA)

Threshold/alarm conditions

Lets you add visual indicaters that use color or highlighting to instantly show when resources are reaching a critical state.

TN3270 ServerDisplays TN3270 Server connections and configuration information.

Traffic/response times

Displays information about the amount of data that is being sent and received (and connection detail), and displays information about host and network response times by station (IP address or domain name), port, subnet, or TN3270 session.

VTAM session data collection

Collects and displays VTAM session information, and session awareness (SAW) data. Also collects VTAM PIUs.


Collects and displays VTAM messages collected through the VTAM Primary Program Operator.

VTAM Resources

Collects and displays VTAM resources, and allows actions to be performed against each VTAM resource.
