Monitoring
the DirectAccess Server
The DirectAccess server
includes an excellent tool to monitor the activity of the DirectAccess
clients. Shown in Figure 14, it provides an overall status of the DirectAccess server,
status and activity of the individual DirectAccess components, and
detailed statistics on the components. The figure shows that the Teredo
components are active, indicating that there are DirectAccess clients
using Teredo but none using IP-HTTPS.
The DirectAccess monitoring
provides information on the traffic activity, data, and control traffic
counters for the following components:
Teredo Relay
Teredo
Server
6to4
IPHTTPS
ISATAP
Network Security
DNS
Server
The status is updated
every 10 seconds. The status indicators for the components will change
depending on the health and activity of the component. The various
states are as follows:
Green indicates
current activity in the component.
Orange indicates the component is idle.
Yellow indicates the component is experiencing issues.
Red indicates that the component has failed.
To use the DirectAccess
server monitoring, run the following steps:
1. | Launch Server Manager on
the DirectAccess server DA1.
|
2. | Expand Features, DirectAccess, and select Monitoring.
|
3. | The details window will show the component status
screen. As connections are made, the status will update every 10 seconds
to show the activity.
|
4. | To see the performance metrics for any given component,
click on the Details button to launch Performance Monitor with the
appropriate counters. For example, click ISATAP Details.
|
5. | Select the Change Graph Type pull-down menu to change
between the different graph types. The Line Graph is shown in Figure 15.
From the selected Packets/sec, it looks like there was a maximum of six
thousand packets per second during the measuring window.

The DirectAccess Monitoring
tool gives access to dozens of key performance metrics in graphical or
tabular format. These metrics are invaluable for monitoring and
troubleshooting the DirectAccess infrastructure.
