sFlowTrend-Pro is configured using the configuration menu, which is accessed using the gears icon . Depending on whether you are logged in as an administrator or not, different options will be available in the menu.

13.1. User preferences

Selecting User preferences brings up the user preferences dialog. This allows you to change the settings for the current user. If you have created users in sFlowTrend-Pro (see Section 13.4, “Configuring user authentication ), then changing the user preferences will apply for the current user wherever they are logged in from. If you have not created any users, then the new user preferences will apply globally.

13.1.1. Setting the switch and interface naming policy

Use the Agent and interface naming pane to tell sFlowTrend-Pro how you would like your switches and their interfaces to be displayed.

13.1.1.1. Setting the switch naming policy

Switches can be displayed using one of the following options:

SNMP IP address
The IP address that sFlowTrend-Pro uses to communicate with the switch via SNMP
sFlow agent address
The IP address that is used by the sFlow agent on the switch to uniquely identify the switch.
DNS name
The domain name obtained from the reverse DNS lookup of the SNMP IP address of the switch. If the reverse DNS lookup fails, the SNMP IP address will be used instead.
sysName
The SNMP sysName obtained from the SNMP MIB. If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 14.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), then SNMP IP address will be used instead.

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.

13.1.1.2. Setting the interface naming policy

Interfaces can be displayed using one of the following options:

ifIndex
The integer that the switch uses to uniquely identify the interface.
ifName
The friendly name assigned to the interface, identifying the card/slot. For example A1, ethernet1/1. If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 14.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), then the ifIndex will be used instead.
ifAlias
A string administratively assigned to the interface often giving useful information about its purpose. For example "Connection to servers". If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 14.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), or the ifAlias is not assigned, then ifIndex will be used instead.

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.

13.1.2. Chart settings

The Chart settings pane allows you to change the appearance of charts in the Network and Thresholds tabs.

In the Network and Thresholds tabs, end hosts can be identified using IP addresses or DNS names. Check the Resolve IP addresses to hostname in charts checkbox to tell sFlowTrend-Pro to use DNS names instead of IP addresses. Note that even if the option to resolve IP addresses is selected, the unresolved address may be shown if sFlowTrend-Pro could not resolve the address, or if the DNS server is responding slowly. In the latter case, addresses will continue to be resolved in the background, and when the page is refreshed the resolved names may be displayed.

The Top N chart entries selector allows you to change the number of entries that are displayed in a top n chart. In the selected minute of the chart, this number of entries will be shown. If there are more entries than this then they are grouped together as Other.

Similarly, the number of protocols displayed in a circles chart can be changed using the Circles chart protocols selector.

13.1.3. Changing your password

If users have been created in sFlowTrend-Pro, you can change your password by filling in the current and new passwords into the Change password pane. The password is changed when OK is pressed on the dialog. If you don't want to change your password when setting other preferences, just leave the current and new password fields blank.

13.1.4. Restore warnings

Checking the Restore warnings 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 behavior of showing warnings.

13.1.5. Show alerts

Leaving this checkbox checked will display alerts about sFlowTrend-Pro, such as notification of software updates. If you clear the checkbox, you will not receive any notifications. This may be useful if, for example, you are using sFlowTrend-Pro to display network status in a public area.
