Stager is a system for aggregating and presenting network statistics. Stager project is generic and can be customized to present and process any kind of network statistics.

The backend collects data 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.

Installation:

If you are upgrading from a previous version of Stager, see the UPGRADE file.

This version of Stager only support Netflow. Future releases will also support roundtrip measurements, SNMP and various passive monitoring measurements.

To run Stager you now need PHP4 CLI with SNMP support. Under debian you can just install php4-cli and php4-snmp

Backend:

1. Create a new Postgresql user that is allowed to create new databases
2. Create a new user that runs the Stager backend. The rest of the installation should be done as this user
3. /stager-install.pl --type=backend --backends=netflow --path=/installation/path/
4. Edit /installation/path/etc/netflow.cfg and /installation/path/etc/getRouterInfo.cfg
5. cd /installation/path/bin
6. ./db_install.pl --backend=netflow
7. Default access control is to give full access to admin user and limited access to guest users. Check /installation/path/lib/getRouterInfo.custom.php if you want to change this.
8. ./getRouterInfo.php -v -v -o
9. ./get-netflow.pl -v --no-missing --delete-old Check for error messages
10. Edit /installation/path/bin/getRouterInfo.sh
11. Edit crontab:
30 0-23/2 * * * $HOME/stager/bin/getRouterInfo.sh -v //How often you run this command depends on how dynamic your network is
45 * * * * $HOME/stager/bin/get-netflow.pl --delete-old
50 1 * * * $HOME/stager/bin/aggregate.pl --backend=netflow --interval='1 day' --no-distributed --manual-mode
45 2 * * 1 $HOME/stager/bin/aggregate.pl --backend=netflow --interval='1 week' --timeformat 'YYYY-IW' --no-cap --no-distributed
50 2 1 * * $HOME/stager/bin/aggregate.pl --backend=netflow --interval='1 month' --timeformat 'YYYY-MM' --no-distributed

Frontend:

1. ./stager-install.pl --type=frontend --path=/installation/path
2. edit /installation/path/config/user.config.php

What's New in This Release:
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.
