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:

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

If you selected the service 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 sFlowTrend-Pro, and then proceed with the installation. After completing the installation, the service is started automatically (if you chose to install it), and you will have the option of immediately launching the client.

If you chose to install sFlowTrend-Pro using a Debian or RPM package, then the normal method for installing these files should be followed for your operating system, after downloading them. Note that Java 6.0 must be installed prior to installing sFlowTrend-Pro. When installing sFlowTrend-Pro using a package file, the home directory cannot be changed.

After completing the installation of sFlowTrend-Pro on Linux as a service, the sFlowTrend-Pro service will be automatically created (as /etc/init.d/sflowtrend-server) and started. The service will also be registered to automatically start when the system is booted, using chkconfig. This is only possible for Linux distributions that use the chkconfig command. Some distributions use other methods for automatically starting services. If the Linux that you are using does not use chkconfig, then you should enter the /etc/init.d/sflowtrend-server service manually as a service to be started at boot time.

If you are installing sFlowTrend-Pro on a system which does not have a graphical user interface, you can either install using a package (see Section 12.2.2, “Installing with a Debian or RPM package”), or using the interactive installer but with a terminal interface. To do this, add the command line option -c to the installer, eg: # /bin/sh installer -c. This will step through the same installation steps that are used for the graphical installer, just using a terminal interface. Please take care to enter the data correctly, as the command line interface is more difficult to use than the graphical interface.

The amount of memory required by the sFlowTrend-Pro service varies considerably, depending on how many sFlow agents are monitored, and the quantity and type of network traffic. The default memory available to the service is generous and suitable for most installations. However, if memory runs low then events will appear in the event log warning of this, and performance of sFlowTrend-Pro may become poor.

To increase the memory available to the service, first go to the bin directory, in the directory on the server where sFlowTrend-Pro was installed. Here there should be a file named sflowtrend-server.vmoptions. Edit this file with a text editor, and add a line to the end with this format:

                -Xmx1800m
                

This will change the memory available to be 1800 MB. The memory can also be reduced in a similar way. After making this change, the sFlowTrend-Pro service must be restarted for the change to take effect.
