Stager is a system for aggregating and presenting network statistics. Though tailored for using NetFlow data from the flow-tools package, it is generic and can be customized to present and process any kind of network statistics. The backend collects data with flow-tools and stores reports in a database, automatically handling the aggregation of hourly statistics into days, weeks, and months. The Web frontend presents data in tables, matrices, or plots. The reports are fully customizable, and their definitions are stored in the database.

Recent releases


Release Notes: The front-end now includes 'Custom reports', which lets you easily create new report types on the fly. The bookmark system was completely rewritten.


Release Notes: The most important new feature of this release is the support for viewing detailed reports directly from raw NetFlow. You can use the reports stored in the Stager database to quickly get an overview of your network, and if you see something suspicious, you can get more details from raw NetFlow. The template system is now XML-based, which makes it easier to customize Stager and to support other types of statistics. This release also contains several bugfixes and code improvements.


Release Notes: Several bugfixes and improved installation instructions.


Release Notes: The backend has been completely rewritten and is now implemented in PHP. The new backend is faster and more generic so that it is easier to add support for other types of statistics. The new backends are also more robust against database down time. In the web GUI, it is now possible to right click on most data to bring up a context menu where it is possible to add custom links.


Release Notes: This release fixes several bugs in both the frontend and backend. The most important fix is that bookmarks with relative times are now working properly. This means that if you create a report that shows data, for example, for the last hour with available data, you can now create a bookmark that will always show data for the last hour with available data.
