Additional Monitor Considerations
Implementing an SNMP DCA or SNMP DCA Base monitor The BIG-IP system includes an SNMP data collecting agent that can query remote SNMP agents of various types, including the UC Davis agent and the Windows 2000 Server agent. The BIG-IP system provides two monitor types that you can use to create a performance monitor for a server that uses an SNMP agent. These two monitor types are: ◆
SNMP DCA Use this monitor when you want to use default values or specify new values for CPU, memory, and disk metrics. When using this template, you can also specify values for other types of metrics that you wish to gather.
◆
SNMP DCA Base Use this monitor when you want to use default values or specify values for metrics other than CPU, memory, and disk usage. When using this monitor, values for CPU, memory, and disk metrics are omitted.
Configuring a server to use its SNMP agent for Dynamic Ratio load balancing consists of three tasks: configuring an SNMP DCA or SNMP DCA Base monitor, associating the monitor with the applicable pool member, and setting the load balancing method on the pool to the Dynamic Ratio method. For more information, see the following chapters or sections of this guide: • To configure an SNMP DCA or SNMP DCA Base monitor, see Chapter 12, Configuring Monitors. • To associate a monitor with the pool, see Chapter 4, Configuring Load Balancing Pools. • To set the load balancing method on the pool to the Dynamic Ratio method, see Chapter 4, Configuring Load Balancing Pools.
