Using SNMP

The Simple Network Management Protocol (SNMP) is a standard protocol used for network management.
SNMP agents collect and store management information in Management Information Bases (MIBs), and
SNMP managers can probe the agents for this information. In addition, SNMP agents can send alarms and
alerts called SNMP traps to the SNMP manager to warn of any problems.
Traffic Server's SNMP agent supports access to two management information bases (MIBs): MIB-2 (a
standard MIB) and the HP Traffic Server MIB. Descriptions of the Traffic Server MIB variables are provided
in the
hp-ts-mib.my
node-specific and cluster-wide information.
To use SNMP on your Traffic Server system, you need to:
Enable Traffic Server's SNMP agent (see Chapter , "Enabling SNMP," below)
Configure Traffic Server to send SNMP traps
Control MIB access to specific hosts
