Enabling Capacity Alerts

Use the capacity alert feature to set managed device capacity thresholds which, when exceeded, will trigger alerts. The managed device will send a wlsxThresholdExceeded SNMP trap and a syslog error message when the managed device has exceeded a set percentage of the total capacity for that resource. A wlsxThresholdCleared SNMP trap and error message will be triggered if the resource usage drops below the threshold once again.

The following procedure describes how to configure the capacity thresholds:

  1. In the Managed Network node hierarchy, navigate to the Configuration > System > More tab.
  2. Expand the Capacity Threshold accordion.
  3. Modify the capacity percentages for any of the thresholds described in Table 1.
  4. Click Submit.
  5. Click Pending Changes.
  6. In the Pending Changes window, select the check box and click Deploy changes.

The following table describes the thresholds that can be configured with this feature.

Table 1: Capacity Alert Thresholds

Threshold

Description

Datapath CPU

Set an alert threshold for datapath CPU capacity. The <percentage> parameter is the percentage of the total datapath CPU capacity that must be exceeded before the alert is sent. The default threshold for this parameter is 30%.

Controlpath CPU

Set an alert threshold for controlpath CPU capacity. The <percentage> parameter is the percentage of the total controlpath CPU capacity that must be exceeded before the alert is sent. The default threshold for this parameter is 45%.

Controlpath memory

Set an alert threshold for controlpath memory consumption. The <percentage> parameter is the percentage of the total memory capacity that must be exceeded before the alert is sent. The default threshold for this parameter is 85%.

Total tunnels

Set an alert threshold for the tunnel capacity of the managed device. The <percentage> parameter is the percentage of the total tunnel capacity of the managed device that must be exceeded before the alert is sent. The default threshold for this parameter is 80%

Total users

Set an alert threshold for the user capacity of the managed device. The <percentage> parameter is the percentage of the total resource capacity that must be exceeded before the alert is sent. The default threshold for this parameter is 80%.

Total APs

The maximum number of APs that can be connected to a managed device is determined by the model type and licenses installed on that managed device. Use this command to trigger an alert when the number of APs currently connected to the managed device exceeds a specific percentage of its total AP capacity. The default threshold for this parameter is 80%.

Total locals

Set an alert threshold for the capacity to support branch and local managed devices on the master managed device. A master managed device can support a combined total of 256 branch and local managed device. The <percentage> parameter is the percentage of the total master managed device capacity that must be exceeded before the alert is sent. The default threshold for this parameter is 80%.

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command configures the capacity thresholds:

Sample Configuration

The following command configures a new alert threshold for datapath memory consumption:

(host) [mynode] (config) #threshold datapath-cpu 90

If this threshold is exceeded then subsequently drops below the 90% threshold, the managed device would send the following two syslog error messages.

May 14 13:13:58 nanny[1393]: <399816> <ERRS> |nanny| Resource 'Control-Path Memory' has gone above 90% threshold, value : 93

May 14 13:16:58 nanny[1393]: <399816> <ERRS> |nanny| Resource 'Control-Path Memory' has come below 90% threshold, value : 87
