SNMP Monitoring
SNMP Monitoring
Introduction
Simple Network Management Protocol (SNMP) is an industry standard
mechanism for monitoring devices over a network, primarily intended to
support service and maintenance activity. With SNMP, devices can be inter-
rogated about the current status of specific device components (reported as
values), and devices can report without prompting (traps) certain condi-
tions that may require immediate attention.
An SNMP system consists of one or more Managed Devices, each of which
has an Agent (software running as a daemon on that device), and a
Network Management System (NMS). The NMS is a software application
running on a computer that communicates with the Agents over the net-
work. The information exchanged is determined by a Management Infor-
mation Base (MIB) database file. The MIB defines the structure and content
of the variables that are available as data for monitoring and reporting. A
Community Name is also used as a rudimentary security measure, acting
as a password to enable communications with the Agent.
For example, a Managed Device may have a cooling fan and thermocouple.
The MIB may define a variable for the thermocouple readout, and a request
for this data can be sent from the NMS to the Agent, which will reply (if the
community name matches) with the current temperature value. The MIB
may also define a Trap that reports a fan failure. Should the device’s fan
stop working, the Agent sends an unprompted message to the NMS. The
NMS can be configured to respond to that Trap message, and may have the
capability to alert maintenance staff of the problem, via an automatic email
message or by triggering a warning alarm.
SNMP is an optional feature for Grass Valley switchers, and requires the
purchase and entry of a license key.
SNMP is an industry standard, however, any third party NMS can be used.
For third party NMS installation & configuration, please contact your
SNMP NMS software vendor.
Grass Valley switchers comply with the following SNMP standards:
