General settings and assumptions
This topic covers the general settings and assumptions for integrating and Entuity Network Analytics. It includes the following sections:
Syslog considerations
Both Entuity Network Analytics and Device Agent can run a syslog server, and the port on which syslog events are received can be configured to a specified value for both the applications.
See Configuring-Entuity-Network-Analytics-to-send-notifications-to-TrueSight-Network-Automation and Administering-remote-device-agents for instructions on configuring syslog settings.
One possible configuration is to have Entuity Network Analytics and a remote device agent running on the same platform and to enable just the remote device agent to listen to system events on port 514.
To disable syslog listening in Entuity Network Analytics
- Edit the following file:
- (Microsoft Windows): ENA_INSTALL\etc\startup_WIN32.cfg
- (UNIX): ENA_INSTALL/etc/startup_UNIX.cfg
Change state=normal to state=none in the following section:
[syslogger]
state=normal
capabilities=polling
type=command
start=${ENTUITY_HOME}\bin\syslogger
directory=${LOGDIR}
is_critical=n
memorylimitmb=4000- Restart the Entuity Network Analytics services.
Mapping display names and host names
With respect to the device database in both the systems, the following table describes how the device name and host name/IP address fields are mapped from Entuity Network Analytics during device database import into .
Entuity Network Analytics | TrueSight Network Automation |
|---|---|
Name | Name |
Polled IP Address | Host Name/IP Address |
To check the Entuity Network Analytics values
- Log on to the Entuity Network Analytics Web UI.
- From the Main Menu, select Administration.
- Under Inventory and Topology, click Device Inventory.
The list of devices appears. Its Polled Name is next to the Device Name field. - Click a network device.
The Summary tab shows various details such as CPU Utilization and Memory Utilization, associated with the device.
To check the device values
- In the GUI, open the Devices page by navigating to Network > Spans > Devices.
The device name is listed in the Name column and host name/IP address is listed in the Address column. - If you need to review the details or change, click the Edit
icon in the Actions column for your device.
Changing web server port settings
Both Entuity Network Analytics and run web servers; therefore if both the applications are running on the same host, you must be careful that that is no HTTP and/or HTTPS port conflict.
A common configuration is to leave at its default settings of 80 (HTTP) and 443 (HTTPS), and set Entuity Network Analytics to use 8082 (Web Port), 8080 (Tomcat Port), 18005 (Tomcat Admin Port), and 8443 (HTTPS).
To change Entuity Network Analytics web server port settings
Re-run the configure program:
- (Windows): ENA_INSTALL\install\configure
or
ENA_INSTALL\install\configure text - (UNIX): /ENA_INSTALL/install/configure text
To change web server port settings
Re-run the InstallShield program, leaving all values at defaults except for the Web Server Port values.
