Platform Team/sugar-stats

Summary

Library to gather Sugar usage statistics. The gathering method is based on sniffing DBus and X11 events.

Supported Sugars

• 0.94

More (0.86+) Sugar versions might be added on demand.

Stats server

This project also contains a server, which is based on active-document and restful-document, and is designed to be a part of the Sugar Network and sugar-server implementations.

A standalone server might be launched using the sugar-stats-server command from project sources. The easiest way is using the binary package sugar-stats-server from Sweets Distribution. The package contains these components:

• sugar-stats-server command,
• /etc/init.d/sugar-stats-server daemon.

For stats transferring from clients, it is useful to use secure, SSL connections. The server configuration needs to be tweaked (and the client should use the same certificate):

• keyfile, path to server's private key,
• certificate, path to server's certificate file.

Server will authenticate clients using SSH keys generated on the client side by Sugar Shell. To let the server check client signatures, OpenSSH-5.6+ should be installed on the server side. For versions lower than 5.6, authentication needs to be disabled using the trust-users parameter.

Configuration

Run the following command to get the current configuration with comments:

sugar-stats-server config

To tweak current configuration, change/create /etc/sugar-stats-server.conf configuration file.

The following important parameters need to be set before using the server. (When sugar-stats-server is installed from packages, they are initialized to meaningful values.):

• stats/stats-root = /var/lib/sugar-network/rrd
  Path to the root directory for placing stats;
• active-document/data-root = /var/lib/sugar-network/users
  Path to the root directory for placing users' metadata;

Implementation notes

• Calculating network.school stat.

Detecting if client host is in school network or not is based on resolving am.i.at.school hostname.

Getting the code

• Gitorious sources repository.
• Binary packages from Sweets Distribution.

In use, the library does not require any building routines, just provide the full path to the active_document/ subdirectory via the PYTHONPATH environment variable.

See the examples/ subdirectory in the sources tree for usage examples.

Library requirements

• RRDtool python binding.

• sugar-client application that uses sugar-stats library.
