Deleting a probe
You can delete a probe you have added to NTA. Deleting a probe from NTA does not delete the data
received from the probe prior to deletion. The data for all deleted probes is retained in the database in
accordance with the NTA server configuration.
To delete a probe:
1. Select Service > Traffic Analysis and Audit > Settings.
2. In the Settings area of the Traffic Analysis and Audit page, click the Probe Management link.
NTA displays all probes in the Probe List displayed in the main pane of the Probe Management
page.
3. Click the Delete icon for the probe you want to delete.
4. Click OK to confirm the deletion of the selected probe.
The Device List reflects the deletion of the selected device.
NOTE:
After you delete a probe, all traffic analysis tasks associated with it are terminated.
Managing NTA servers
The NTA service module can be deployed on the IMC base platform server or on separate server in a
master/subordinate relationship to the base platform server. The NTA Server Management feature
allows you to manage the configuration of all NTA servers, whether or not the NTA server is local to the
IMC base platform server. Each NTA server is added to the service list when the NTA server is deployed.
When the NTA service module is deployed on the IMC Platform server, the server name is the loopback
address or 127.1.0.1 by default. When the NTA service module is deployed on a server other than the
platform server, the server name is the server IP address by default. When the NTA service module is
uninstalled, the installation program removes the NTA instance from the server list.
You can deploy up to 10 NTA servers for one NTA module. Multiple servers can share load to improve
the NTA server performance. To use no more than ten NTA servers, you only need to purchase a license
for one NTA module and ensure that the total number of managed device nodes does not exceed the
limit of the license. To use more than ten NTA servers, you must purchase more than one set of the IMC
Platform and NTA module.
Viewing the NTA server list
1. Select Service > Traffic Analysis and Audit > Settings.
2. In the Settings area of the Traffic Analysis and Audit page, click the Server Management link.
NTA displays all servers in the Server List displayed in the main pane of the Server Management
page.
