Chapter 6 Configuring Real Servers and Server Farms
Configuring Health Monitoring
Step 3 Click Add to add an entry, or select an existing entry, and then click Edit to modify it. The SNMP OID
configuration pane appears.
Step 4 In the SNMP OID field, enter the OID that the probe is to use to query the server for a value. Valid entries
are unquoted strings with a maximum of 255 alphanumeric characters in dotted-decimal notation, such
as .1.3.6.1.4.2021.10.1.3.1. The OID string is based on the server type.
Step 5 In the Maximum Absolute Server Load Value field, enter the OID value in the form of an integer and to
indicate that the retrieved OID value is an absolute value instead of a percent. Valid entries are integers
from 1 to 4294967295.
When the ACE sends a probe with an SNMP OID query, the ACE uses the retrieved value as input to the
least-loaded algorithm for load-balancing decisions. By default, the ACE assumes that the retrieved OID
value is a percentile value. Use this option to specify that the retrieved OID value is an absolute value.
Step 6 In the Server Load Threshold Value field, specify the threshold at which the server is to be taken out of
service:
When the OID value is based on a percent, valid entries are integers from 1 to 100.
When the OID is based on an absolute value, valid entries are from 1 to the value specified in the
Maximum Absolute Server Load Value field.
Step 7 In the Server Load Weighting field, enter the weight to assign to this OID for the SNMP probe. Valid
entries are integers from 0 to 16000.
Step 8 Do the following:
Click Deploy Now to deploy this configuration.
Click Cancel to exit this procedure without saving your entries and to return to the SNMP OID table.
Click Next to deploy your entries and to add another item to the SNMP OID table.
