Configuring the Resource Usage Threshold for Real Server

You can configure the ACE to issue SNMP traps and syslog messages at the real server level for the

following monitored resources:

• Bandwidth—Thresholds are applied to the aggregated bandwidth for a particular real server.

• Concurrent connections—Thresholds are applied to the aggregated concurrent connections for a

particular real server.

• Connection rate—Thresholds are applied to the aggregated connection rate for a particular real

server.

All the resources configured under the server farm are monitored at a particular real server level. For

each resource, you can specify the high, low, and watermark thresholds.

Procedure

Step 1 Choose Config > Virtual Contexts > context > System > Resource Usage Threshold > Real Server

Threshold.

The Real Server Threshold table appears.

Step 2 Click Add to add a new real server threshold, or select a real server threshold you want to modify, and

then click Edit. The Real Server Threshold screen appears.

Step 3 In the Real Server Name field, enter the name of the real server that is associated with the selected

server farm.

Step 4 In the Server Farm Name field, enter the name of the server farm.

Step 5 For each resource, specify the high, low, and watermark percentages.

Enter the percentage values using the following guide:

1 <= Low < Watermark < High <= 100 (percent)

Decimal values are not allowed.

Step 6 Do one of the following:

• Click Deploy Now.

• Click Cancel to exit this procedure without saving your selection and to return to the Real Server

Threshold table.
