Using snmp_dca
The snmp_dca template is used for load balancing traffic to servers that are
running an SNMP agent, such as UC Davis or Windows 2000. In addition to
defining ratio weights for CPU, memory, and disk use, you can also define
weights for use by users. Figure 4.62 shows the snmp_dca monitor
template.
For detailed information on using the snmp_dca template, see Configuring
SNMP servers, on page 4-16.
Using snmp_dca_base
Like the snmp_dca template, the snmp_dca_base template is for load
balancing traffic to servers that are running an SNMP agent, such as UC
Davis or Windows 2000. However, this template should be used only when
you want the load balancing destination to be based solely on user data, and
not CPU, memory, or disk use. Figure 4.63 shows the snmp_dca_base
monitor template.
For detailed information on using the snmp_dca_base template, see
Configuring SNMP servers, on page 4-16.
