Cookies used by the Piwik metrics adapter

App Suite UI supports different analytic solutions like Piwik. If the feature "Piwik" is enabled (default: disabled) for a installation, the included Piwik adapter generates a random hash on the client to identify the user later on as a unique user. The hash does not contain any user related data and is only generated based on a random number.
