An Introduction to Integrating Partner Applications with VPO
VPO Conceptual Overview
Chapter 138
Collecting Management Information
VPO provides extensive collection services for management information.
The agents gather management information originating from a variety of
sources and when an exception is detected, they generate messages from
the collected information.
All messages and events are intercepted by the agent at each managed
node, filtered and classified, and then forwarded to the responsible
management server. In an environment with multiple servers, the
responsible server is determined by the manager-of-manager (MoM)
configuration template. SNMP traps can also be intercepted on managed
nodes if a trap template has been assigned to the nodes.
Logfiles and SNMP Traps
Important message sources include application and system logfiles, and
SNMP traps. The VPO logfile encapsulator extracts important events
from logfiles, and the event interceptor intercepts SNMP traps broadcast
by components of the network. Multiple character sets for logfiles are
supported, and conversion routines (e.g., for binary logfiles) can be
applied to consolidate the message format, improve the problem text, set
event attributes, etc. System messages normally displayed on an MPE/iX
system console are an additional source of VPO messages.
Agent Message API
Management information, generated by applications or customer
programs or scripts, can even be sent directly to the VPO agent on any
managed node by way of the Agent Message API, see Chapter 4, “Using
the VPO Application Programming Interfaces,” on page 163.
