The AppServer Health Monitoring agent is an iControl plug-in based on Net-SNMP — a popular open-source health monitoring package (see www.net‑snmp.org) consisting of an SNMP daemon (snmpd), an SNMP agent, and several utilities. iControl’s customized version of Net‑SNMP allows a third party SNMP manager to monitor various aspects of an Application Server (e.g. network interface statistics, processor/memory usage, disk space) as well as the condition of essential iControl services (GSM, RMID, Densité Manager, etc.).

Both types of agents are discussed in detail in the following pages.
