HP Insight Management Agents architecture for Windows servers

8
Management Agents architecture uses SNMP Trap notifications to deliver the alerts to the SIM
server, which processes and then displays them on the SIM console.
Several different components of the Insight Management architecture, including parts of each of the
four Insight Agents, monitor the MIB and process the information to determine when to issue alerts:
 Remote Alerter Threads—Each Insight Management agent has a remote alerter thread that
monitors its portion of the HP MIB in the Windows Registry for registry change events. When the
thread detects a change that requires an alert, such as a threshold being exceeded, it writes an
event to the Windows Event Log with a pre-defined Event ID.
 The HP Trap Thread—This extension to the Microsoft SNMP Agent Service scans the Windows
Event Log for alert events that have been written to it by the Remote Alerter Threads. It also
detects other key events in the log that should generate an alert.
 The Microsoft SNMP Agent Service—Based on the events selected by the HP Trap Thread, the
SNMP Agent Service generates the actual SNMP Traps and sends them to the SIM server for
display on the management console.
Figure 2 shows the Insight Manager alerting architecture. This is a slightly more detailed view of one
section of the overall Insight Agents architecture shown in Figure 1.
