n2 is a client/server system for transmitting forensic snapshots from a number of hosts to a receiver node. This receiver collects statistics and is able to present an overview of the current and historical situation on a server. n2 provides a robust solution for real-time monitoring, optimizing performance, and analyzing crashes.
statsmodels is a Python package which provides a complement to scipy for statistical computations, including descriptive statistics and estimation of statistical models. The main included model categories are linear, discrete, generalized linear, and robust linear, and, in time series analysis, AR, ARMA, and VAR. It also includes statistical tests mainly for regression diagnostics. statsmodels was renamed from scikits.statsmodels.
The ServerUsage system collects and processes statistical information from computers running a GNU/Linux Operating System. It is composed of two subprojects, the ServerUsage-Client to collect usage statistics (via a SystemTap module) and send them to a remote server via TCP, and the ServerUsage-Server to collect all statistics from different clients and aggregate them in a SQlite database table. A PHP Web service is available on the server module to extract information or display graphics.
