Chapter 14 Monitoring Your Network

Using Dashboards to Monitor the ACE System and Virtual Contexts

• VLANs—Total count of VLANs configured and the count of VLANs based on operational status -

Up and Down. A hyperlink enables you to view traffic summary information based on the identified

state (see the “Monitoring Traffic” section on page 14-21). For example, if you click the Up

hyperlink, you will see only the VLAN interfaces that currently have an operational status of Up.

• Port Channels—Total count of port channels configured on the ACE appliance based on their

operational status of Up and Down. A hyperlink enables you to view traffic summary information

based on the identified state (see the “Monitoring Traffic” section on page 14-21). For example, if

you click the Up hyperlink, you will see only the port channels that currently have an operational

status of Up.

• BVIs—Total count of BVI interfaces and the count of BVI interfaces based on their operational

status of Up and Down. A hyperlink enables you to view traffic summary information based on the

identified state (see the “Monitoring Traffic” section on page 14-21). For example, if you click the

Up hyperlink, you will see only the BVI interfaces that currently have an operational status of Up.

• Certificates—Total count of SSL certificates and the count of SSL certificates that are expiring

beyond 30 days, expired, or that are expiring within 30 days. A hyperlink accesses a popup window

for you to view the SSL certificates list based on the selection, displaying the certificate name,

device name, days to expire, expiration date, and the date it was evaluated for you to determine the

days to expire. Certificates are considered expired it their expiration date is within the next day

(rounded down the next day). A hyperlink in the device name allows you to navigate to the

context-based SSL Certificate configuration page (see the “Using SSL Certificates” section on

page 9-6).

Note The Certificates information does not apply to the ACE NPE software version (see the

“Information About the ACE No Payload Encryption Software Version” section on

page 1-2).

This data is collected during discovery as well as during periodic monitoring polling. The timestamp

shown in the status bar indicates a varying poll time; that is, different virtual contexts were polled and

those context had different time stamps. The earliest time stamp of the polled virtual contexts is

displayed in the status bar.

All counts shown in the Device Configuration Summary table are based on the operational status of the

monitored objects listed above.

• Out Of Service—Indicates any status other than In Service (for example, Out Of Service, Failed, or

Disabled).

• Status not available—Indicates that DM was unable to poll the operational status of this object. The

display of this operational status could be due to polling errors or the device was unreachable. Also,

if a poll was recently initiated, this operational status could indicate that DM is in the process of

collecting data.

• Status not supported—Indicates that the device does not have the capability to provide an

operational status of this object. The display of this operational status could be due to missing

SNMP instrumentation on the ACE appliance.
