iControl as SNMP Agent
iControl SNMP agents allow third party SNMP managers, such as Spectrum, to monitor an
iControl configuration. There are two types of iControl SNMP agents:
• the GSM SNMP agent
• the AppServer Health Monitoring agent
AppServer Health Monitoring Agent
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.
Configuring the GSM as an SNMP Agent
Any iControl GSM can be made to act as an SNMP agent. The GSM SNMP agent reports the
status and alarms of Grass Valley’s Densité and Imaging cards and frames (along with every
other alarmable entity visible in the GSM Alarm Browser) in the form of an SNMP table
(see
"The GSM Alarm Status Table" , on page 417). This table can be queried or polled for alarms
and statuses by any third party SNMP Manager.
You can configure the GSM to act as an SNMP agent for all alarms or you can configure the
GSM as an SNMP agent for an individual alarm. Additionally, you may have multiple instances
of the GSM-as-SNMP-agent when the agents represent different alarms.
