This page provides details about the installation and management of updates and extension packages (modules). In the Installed Packages table, the actual Flowmon Networks device version and all installed modules including their versions and buttons for management (Stop, Start, Uninstall) are shown. To install a new version of the Flowmon Probe software or a module, either click Import package and install it or click Install this package in the Action column of the desired package in the Available packages.

WARNING

Once the installation process starts, you MUST NOT reboot or turn off your device until the process is finished. When it finishes successfully, the green message appears. If there is an error, a red message appears. Do not restart or shut down your device during the installation processs, and wait until it is successfully finished! Sometimes it can take tens of minutes. If the installation does not finish successfully or there is an error message and a blank page appears in your browser, contact support.

The Available packages table shows newer versions of already installed packages that are available and downloaded from the services.flowmon.com portal. Each package is only downloaded if there is a valid license for this package.

A description of what happens when each of the available options is enabled is provided below:

  • Automatic package download: The system checks the portal for new packages automatically every 10 minutes. You can trigger this option manually by clicking Update the package list.
  • Display new versions notification: A notification message appears about the new Flowmon version in the User Interface (UI). This setting is always enabled after an upgrade.
  • Send notifications about new versions to administrators: A notification about the new version is sent to all users in the admin group.
  • Participate in beta program: Beta versions are also downloaded. Beta versions offer the opportunity to use the latest updates and features, but come with an increased risk of experiencing issues.

Once the package is downloaded, its checksum is computed. If it was downloaded correctly, it can be installed by clicking the Install button. The UI switches to Maintenance mode while updating the Flowmon package to versions 12.4.1 and newer. The maintenance page displays the update status and the rest of the Flowmon UI is inaccessible until the update completes.

If the package is installed correctly, the downloaded package gets removed during the next update from the portal.

The package can also be uploaded to the Available Packages list manually. Upload the file using SSH to the /data/packages directory and run the command:

/usr/bin/php /var/www/shtml/index.php Cli:AddPackageManually
-package_name=<package-name>
-major_version=<major-version>
-minor_version=<minor-version>
-build=<build-number>
-beta=<true|false>
-filename=<package-file-name>
  • package_name - the name of the package without a version label (for example, flowmonplug-ads)

  • major_version, minor_version and build - the number in the version label, for example, in the package flowmonplug-ads-v6.04.01, the numbers 6, 4, and 1 in the same order. If a number is missing in the package name, use 0 instead.

  • beta - the beta parameter is true (for beta packages) or false (for stable packages)

  • filename - the name of the file uploaded to /data/packages

Example

/usr/bin/php /var/www/shtml/index.php Cli:AddPackageManually
-package_name=flowmonplug-ads
-major_version=6 -minor_version=4
-build=1 -beta=false
-filename=flowmonplug-ads-v6.04.01.tar.gz

If the manual package upload is successful, it is shown in the Available packages table. In this case, the package integrity is not checked (it will be done during installation) and the package can only be deleted manually by clicking Delete.
