2.1. Installation

sFlowTrend-Pro is installed using an installer, obtained from Download the appropriate installer file for your system: either Windows, Linux or Mac. For Linux, you can download either an interactive installer, a Debian package (.deb file), or an RPM file, depending on your preference. If you are installing on Windows, Mac or using the interactive installer on Linux, follow the instructions in Section 2.1.1, “Using the interactive installer”. For more information on installing with a Debian or RPM package, see Section 2.1.2, “Installing with a Debian or RPM package”.

After sFlowTrend-Pro is installed, you must configure a license. When the client first connects to the server, a dialog should pop up automatically. This dialog allows you to enter the license number (or choose to use the free version, sFlowTrend). If the dialog does not appear, or you would like to change the license, see Section, “Configuring the license” for more information. Note that normally sFlowTrend-Pro will use the Internet to download the license key, once the license number has been entered. If a proxy configuration is required for the server to connect to the Internet, please make sure that the proxy is correctly configured (see Section 13.2.4, “Proxy configuration”).

On initial installation, until you configure the license you cannot use the rest of the product; this means that the proxy also cannot be configured. To work around this, if you have to configure a proxy, first select the option to use the free sFlowTrend license, then configure the proxy, and finally go back to the license dialog and enter your actual license number.

If the system has no Internet connectivity at all, then the license key can be entered manually. First, request a manual license key using a support request at Once you have the key, then enter it as described in Section, “Configuring the license”.

2.1.1. Using the interactive installer

On Windows, Mac, or if using the interactive installer on Linux, follow the instructions in this section after downloading the installer file.

On Windows, just run the file by double-clicking it.

On Mac, mount the disk image by double clicking on it, then run the installer contained in the disk image by double clicking on it. Remember to unmount the disk image when finished.

On Linux, you will need to be root to install sFlowTrend-Pro. If you choose to use the interactive installer, run the installer by typing # /bin/sh installer where installer is the file you downloaded. Alternatively make the file executable and then run it.

When you launch the installer, you will be presented with a sequence of installation steps. After the initial welcome screen, you will need to accept the license agreement. Next, choose the directory where you would like to install sFlowTrend-Pro; it is recommended that you accept the default location. In the next screen, you can chose which components to install:

sFlowTrend-Pro service
Select this option to install the service and the local Java client (optionally used to connect to the service on the same system).
sFlowTrend-Pro remote client
Select this option to install the remote Java client, which you can use to connect to other systems running the service. We recommend that you use the web interface instead of the remote Java client.

You can install both the service and the remote Java client on the same system, if desired. You must select at least one of the options to complete the installation.

On the next screen you will be prompted for the sFlowTrend-Pro home directory. This is where the database, log files and custom configuration is stored. Using the default directory is recommended, although it can be changed if you would rather use a different location. In particular, please make sure that enough disk space is available to store the database. The disk space required will depend on the type of network traffic seen, and the number of switches being monitored. Several gigabytes will be enough for most installations. Once you have chosen a location, it cannot be changed without reinstalling sFlowTrend-Pro.

The remaining screens allow you to select the menu location to install the shortcuts for launching the sFlowTrend-Pro Java clients, and then proceed with the installation. After completing the installation, the service is started automatically, and you will have the option of immediately connecting to sFlowTrend-Pro using a browser, or to launch a Java client.

2.1.2. Installing with a Debian or RPM package

If you choose to install sFlowTrend-Pro using a Debian or RPM package, download the appropriate package and then follow your operating system's normal method for installation. Note that Java version 8 (or later) must be installed prior to installing sFlowTrend-Pro. When installing sFlowTrend-Pro using a package file, the home directory cannot be changed.
