Systems Management Business System: Topology Display Subsystem

The Topology Display subsystem consists of the following Tivoli NetView for z/OS components:

Relationships are reported between Topology Display subsystem components and workstation servers.

Tasks are provided that allow you to:

The following monitors are provided to measure availability and resource utilization of the Topology Display subsystem components:

Each monitor supports the following tasks:

Set Threshold
Sets the conditions when threshold events are sent
Set Polling Interval
Sets the interval between times the current value of a monitor is checked against the thresholds established by Set Threshold
Query Value
Retrieves the current value of the monitor
Query Level
Retrieves the current threshold severity level

CNMTAMEL Component

CNMTAMEL Component Tasks

None

CNMTAMEL Connection Tasks

None

CNMTAMEL Monitors

TDS State Monitor

Reports on the connection between CNMTAMEL and the workstation data server. This monitor is mapped to the IP NETCONV and LU6.2 NETCONV relationships.

PPI Status Monitor

Reports on the connections between CNMTAMEL and GMFHS. The monitor is mapped to the Tivoli NetView PPI relationship.

CNMTAMEL Relationships

IP NETCONV

CNMTAMEL uses this relationship to send and receive data to and from the workstation data server. The connection uses the IP transport.

Note: If the NETCONV session was being used to transport the instrumentation data then the connection will not be removed. However, all the components reported on the session will be changed to the UNKNOWN state.

LU6.2 NETCONV

CNMTAMEL uses this relationship to send and receive data to and from the workstation data server. The connection uses the SNA LU6.2 transport.

The connection is removed when the NETCONV session is stopped.

Note: If the NETCONV session was being used to transport the instrumentation data then the connection will not be removed. However, all the components reported on the session will be changed to the UNKNOWN state.

NV PPI

CNMTAMEL uses this relationship to send and receive data to and from GMFHS.

RODM Component

RODM Component Tasks

Warm Start RODM

Select this task to warm start RODM.

Stop RODM

Select this task to stop RODM.

Cold Start RODM

Select this task to cold start RODM. RODM will be started using the options type=coldforc,init=ekglislm. To change the options, modify the Tivoli NetView for z/OS CLIST CNMETDTK.

After cold starting RODM, you will need to restart GMFHS.

Common Tasks for Topology Display Subsystem Components

Query State

Select this task to query the current state of the selected component. If GMFHS is not active, Query State will always return DOWN for the RODM component, SNA topology manager component, or any other managers, such as MSM.

Set Pulse

Select this task to modify the polling interval associated with the heartbeat monitor for the selected component.

Query Connections

This task retrieves the relationship instances to and from the selected component.

Query All Monitor Thresholds

Select this task to query thresholds for all monitors associated with the selected component.

Query All Monitor Polling Intervals

Select this task to query the polling intervals associated with all monitors defined for the selected component.

Common Monitors for Topology Display Subsystem Components

State

Reports whether the component is UP or DOWN.
