Considerations when installing and configuring the Insight

Agents

In addition to the latest device drivers and utilities for HP ProLiant servers, the ProLiant Support Packs

contain updated Insight Management Agents. ProLiant Support Packs are developed and tested

concurrently with HP SmartStart releases. They provide a tested and trouble-free method for keeping

the Insight Agents on managed servers up to date.

The various software components that comprise the HP SIM environment use several different system

ports for communications. Table 5 lists the different ports used and the software components that use

them.

When using HP SIM as a management solution, it is important to keep these port addresses open

within the internal networks. Internal firewalls that block these ports can cause parts of HP SIM to

function improperly.

The Insight Management Agents operate by collecting information on the managed server at regular

intervals. This is commonly referred to as polling. The Insight Agents Architecture allows an

administrator to configure how frequently the agents collect data from the managed server. The data

collection interval can be set from as short as every five seconds to once every hour.

Using a short data collection interval allows the agents to provide more frequently updated

information on the server, which may prove useful for closely monitored systems. However, a shorter

data collection interval consumes more system resources and could affect system performance at some

level. The recommended setting for the data collection interval is two minutes, which is also the default

value. Administrators can configure the data collection interval under the SNMP Settings tab of the

Management Agents configuration utility, from the SMH, or from HP SIM.
