Generating test data – Introducing the Piwik Platform
9 octobre 2014, par Thomas Steur — DevelopmentThis is the next post of our blog series where we introduce the capabilities of the Piwik platform (our previous post was How to create a command). This time you’ll learn how to generate test data.
Developers are developing on their local Piwik instance which usually does not contain useful data compared to a real Piwik installation in production (only a few test visits and a few tests users and websites). The ‘VisitorGenerator’ plugin lets you generate any number of visits, websites, users, goals and more. The generator makes sure there will be data for each report so you can easily test anything.
Getting started
In this series of posts, we assume that you have already installed Piwik. If not, visit the Piwik Developer Zone where you’ll find the Installation guide for developers.
Installing the VisitorGenerator plugin
The easiest way to install the plugin is by using the Marketplace in Piwik itself. It is accessible via Settings => Marketplace => Get new functionality. There you’ll find the plugin “VisitorGenerator” which you can install and activate in one click.
If your Piwik instance is not connected to the internet you can download the plugin from the VisitorGenerator page on the Marketplace. Afterwards you can install the plugin by going to Settings => Marketplace => Uploading a plugin and uploading the previously downloaded ZIP file.
If you have already installed the plugin make sure it is activated by going to Settings => Plugins.
Generating websites
After you have installed the plugin you can add as many websites as you need. This is useful for instance when you want to test something that affects many websites such as the ‘All Websites’ dashboard or the Websites manager. To generate any number of websites use the following command :
./console visitorgenerator:generate-website --limit=10
This will generate 10 websites. If you need more websites simply specify a higher limit. In case you are wondering the names and URLs of the websites are randomly generated by the Faker PHP library.
Generating goals
In case you want to test anything related to Goals you should execute the following command :
./console visitorgenerator:generate-goals --idsite=1
This will generate a few goals for the specified site. The generated goals are defined in a way to make sure there will be conversions when generating the visits in the next step.
Generating visits
To generate visits there are two possibilities. Either via the Piwik UI by going to Settings => Visitor Generator or by using the command line. The UI is a bit limited in generating visits so we recommend to use the command line. There you can generate visits as follows :
./console visitorgenerator:generate-visits --idsite=1
This will generate many different visits for the current day. Don’t worry if it takes a while, it will insert quite a few visits by default.
In case you want to generate visits for multiple days in the past as well you can specify the
--days
option../console visitorgenerator:generate-visits --idsite=1 --days=5
Providing your own logs
Half of the generated visits are randomly generated and half of the visits are based on real logs to make sure there is data for each report. If you want to generate visits based on your own logs for a more realistic testing just place your log files in the
plugins/VisitorGenerator/data
folder and make sure the file name ends with.log
. You can find a few examples in the VisitorGenerator data folder.To generate visits based only on real log files then use the
--no-fake
option../console visitorgenerator:generate-visits --idsite=1 --no-fake
All generated visits will come from the logs and no random visits nor random fake data will be used.
Advanced features
We are regularly adding new commands, tools and runtime checks to make your life as a developer easier. For instance you can also generate users and annotations. In the future we want to extend the plugin to create visits in the background to make sure there will be constantly new actions in the real time report.
Are you missing any kind of generator or any other feature to make your life as a developer easier ? Let us know by email, we are listening !

ffmpeg : specify/force pixel format for input H.264 video
30 juillet 2017, par AndreGI have some MP4 video files missing the pixel format in their header information. I have already tried setting
probesize
andanalyzeduration
to their maximum values 2147483647 but that didn’t help.So I know these videos are probably corrupt but if this is the only information missing I was thinking I could maybe recover them by rebuilding their header information or somehow decoding them by forcing a pixel format. Does anyone have any idea if this is possible ? Some more background on the file :
