Monitoring Messages
CA-Unicenter for Tandem—Event Management Function
The CA-Unicenter Event Management facilities provide for integrated message 
management across a heterogeneous network environment. This function makes it easy 
to:
•
Identify events that require special handling
•
Automatically detect events and initiate response actions
•
Route messages to central monitoring nodes in a network
You can, for example, distinguish among production control messages, security 
messages, and problem messages, and route each type of message to a different 
monitoring console.
Open Notification Service (ONS)
ONS provides two primary functions for a network management tool. First, ONS acts as 
a server to gather Event Management Service (EMS) events from the Tandem system 
event log, $0. Second, these events are translated into Simple Network Management 
Protocol (SNMP) traps and are sent to a network management tool through the Tandem 
SNMP Agent. ONS gathers EMS events from the following Tandem subsystems:
•
Object Monitoring Facility (all events)
•
Transaction Monitoring Facility (all events)
Tandem Service Management Package (TSM)
You use the TSM application to establish a connection with a Himalaya S-series server. 
The TSM application enables you to communicate with a Himalaya S-series server even 
when the NonStop Kernel operating system is not running.
The TSM Notification Director receives notifications and incident reports from the 
Himalaya S-series server, displays them, and allows you to take action or forward the 
incident reports to your service provider for resolution. The TSM Notification Director 
runs on the TSM workstation at all times, even when the TSM application is not being 
used.
Service processor (SP) event messages are EMS event messages generated by the master 
service processors (MSPs) on Himalaya S-series servers. The TSM Notification Director 
can gather SP event messages directly from the MSPs, allowing SP messages to be 
received when the NonStop Kernel operating is not running. The TSM Notification 
Director receives SP event messages only when the TSM application is running and a 
low-level link is active.
The system down message is a special type of SP event message that is generated by the 
MSPs when all processors on the Himalaya S-series server have halted or the server has 
been powered off. The system down message is sent to all TSM workstations recognized 
by the Himalaya S-series server.
For more information on TSM and its message monitoring capabilities, see the TSM 
Online User Guide and the online help, available when you are running TSM.
