== Summary ==
Library to gather Sugar [[Platform_Team/Usage_Statistics|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 [[Platform_Team/Active_Document|active-document]] and [[Platform_Team/RESTful_Document|restful-document]], and is designed to be a part of the [[Platform_Team/Sugar_Network|Sugar Network]] and [[Platform_Team/Server_Kit/sugar-server|sugar-server]] implementations.
A standalone server might be launched using the {{Code|sugar-stats-server}} command from project sources. The easiest way is using the binary package [http://download.sugarlabs.org/packages/SweetsDistribution:/Factory/ sugar-stats-server] from [[Sweets Distribution]]. The package contains these components:
* {{Code|sugar-stats-server}} command,
* {{Code|/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 [[Sugar_Server_Kit/sugar-client#Usage statistics|client]] should use the same certificate):
* {{Code|keyfile}}, path to server's private key,
* {{Code|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 {{Code|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 {{Code|/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.):
* {{Code|stats/stats-root <nowiki>=</nowiki> /var/lib/sugar-network/rrd}}<br>Path to the root directory for placing stats;
* {{Code|active-document/data-root <nowiki>=</nowiki> /var/lib/sugar-network/users}}<br>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 {{Code|am.i.at.school}} hostname.
== Getting the code ==
* Gitorious [http://git.sugarlabs.org/desktop/stats sources] repository.
* Binary [http://download.sugarlabs.org/packages/SweetsDistribution:/Factory/ packages] from [[Sweets Distribution]].
In use, the library does not require any building routines, just provide the full path to the {{Code|active_document/}} subdirectory via the {{Code|PYTHONPATH}} environment variable.
See the [http://git.sugarlabs.org/desktop/stats/trees/master/examples examples/] subdirectory in the sources tree for usage examples.
===Library requirements===
* RRDtool [http://oss.oetiker.ch/rrdtool/prog/rrdpython.en.html python binding].
== See also ==
* [[Platform_Team/Server_Kit/sugar-client|sugar-client]] application that uses sugar-stats library.
