Select the→ menu item to customise various aspects of sFlowTrend-Pro. On an Apple Macintosh, the customisation dialog is accessed from by selecting from the application menu.
Use the View tab, to tell sFlowTrend-Pro how you would like your switches and their interfaces to be displayed and whether end hosts are identified using IP addresses or DNS names.→ menu item,
Switches can be displayed using one of the following options:
If the SNMP IP address or the sFlow agent address option is chosen, the switches will be listed in numerical order in the Switch selector in the Charts and Interfaces tabs. For other options, the switches will be listed in alpha-numeric order, even if an IP address is shown because the name is not available.
Interfaces can be displayed using one of the following options:
If the ifIndex option is chosen, the interfaces will be listed in numerical order in the Interface selector in the Charts tab. For other options, the interfaces will be listed in alpha-numeric order, even if the ifIndex is shown because the name is not available.
Select the SNMP tab to configure the SNMP settings which will be used for all switches. These settings will be used when querying switches for the friendly names for the switches and interfaces. You can ask sFlowTrend-Pro to communicate with the switches using SNMP v2c or SNMP v3. If sFlowTrend-Pro is to use SNMP to configure the switches to send sFlow, then the SNMP settings must allow write access to the sFlow MIB, and the switch must allow the system running sFlowTrend-Pro write access.→ menu item,
These global settings can be explicitly overridden for a specific switch (see Section 13.2, “Configuring agents in sFlowTrend-Pro ”).
When these global settings are changed, sFlowTrend-Pro will start using the new settings to communicate with switches that use the global settings.
Select the Advanced tab to view and configure some less commonly used settings:→ menu item,
Checking this checkbox will cause sFlowTrend-Pro to display warnings asking you to confirm actions, for example when deleting switches or when exiting sFlowTrend-Pro. When these warnings are shown, you can ask sFlowTrend-Pro not to show these warnings again. This checkbox can be used to restore the behaviour of showing warnings.
Leaving this checkbox checked will display alerts about sFlowTrend-Pro, such as notification of software updates, on this client. If you clear the checkbox, you will not recieve any notifications on this client. This may be useful if, for example, you are using sFlowTrend-Pro to display network status in a public area.
Leaving this checkbox checked will allow sFlowTrend-Pro to send reports of software problems to InMon. We appreciate this feedback, and it helps us improve sFlowTrend-Pro. If you do not want problem reports to be sent, then clear this checkbox.
Allows you to change the directory used by sFlowTrend-Pro for storing information. The directory is configured differently, depending on whether you are running sFlowTrend-Pro as an application, or as a service.
If you are running as an application, then the home directory is used to store traffic and log data, and custom configuration information. If you have enabled user authentication (see Section 13.6, “Configuring user authentication ”, then only Administrators can change the home directory. If you change the home directory, all currently saved traffic data and custom configuration information will be lost. sFlowTrend-Pro must be restarted for the change to take effect.
If you are running sFlowTrend-Pro as a service, then two home directories are shown in advanced settings: one for the client, and one for the server:
If a proxy server is required for connectivity to the Internet, this is configured by selecting the Proxies tab. The proxy can be set for both the client and the server.→ menu item,
It is important to set the proxies if required. The server uses Internet connectivity to download the initial license and any subsequent updates (for example, if you renew the license), and the client uses the Internet to display product alerts.
The configuration available for the proxies is as follows:
No proxy will be used.
Sets the proxy to be the same as the system default. Note that the system default settings are not necessarily those defined in the browser that you use: on Windows, the system default settings are those configured in→ → .
On some Operating Systems the system default setting is not available. In this case, please use the manual proxy configuration if a proxy is required.
Allows configuration of a proxy server only for sFlowTrend-Pro. The address of the proxy server and the TCP port used to communicate with it should be entered into the Http proxy and port fields, respectively.
If there are any hosts that do not require a proxy, you can enter the address of these hosts into the Do not proxy for hosts field. Multiple hosts can be entered here, separated by newlines, semicolons or commas, and wildcards can be used to represent a range of hosts (for example, "*.inmon.com").
sFlowTrend-Pro uses a Simple Mail Transfer Protocol (SMTP) server to send email notification of events. The SMTP server receives messages from sFlowTrend-Pro and forwards them to their destination. The following SMTP server settings must be configured:
You can test the SMTP server configuration by clicking. An email will be sent to the sender email address that you have entered. If the configuration fails, sFlowTrend-Pro will show an error message.
Select the Advanced sFlow tab to view and configure some less commonly used sFlow related settings:→ menu item,
If the system you are running sFlowTrend-Pro on has multiple IP addresses and you are using SNMP to configure switches to send sFlow you can use the sFlow collector address to select the address that is configured on the switches as the sFlow collector or receiver address (see Section 13.2.1, “Adding a switch that is to be configured via SNMP”). Note that sFlowTrend-Pro will listen for sFlow on all addresses, and unless you are using SNMP configuration this setting is not used.
If there is a NAT device between the system running sFlowTrend-Pro and the switches, or you are running sFlowTrend-Pro in a virtual or container environment where a virtual NAT device is used, you can use an advanced setting (see sflowtrend.natReceiverAddress) to add the public IP address and port of the NAT device to the sFlow collector address selection list. When you select the NAT address and port as the sFlow collector address and you are using SNMP to configure switches to send sFlow, the switches will be configured to send sFlow to the NAT address and port.
