2 Overview Part I Introduction 1 Introduction Jens Rehsack () Unix::Statgrab - System Monitoring / 28
3 Introduction Audience Audience Developer who wants to create or improve monitoring software Developer who wants to evaluate system stats for content sensitive code paths Developer who wants to to learn the difference to earlier libstatgrab / Unix::Statgrab API Developers or Operators (Admins) who wants to learn about measurement of statistic values of the machine Jens Rehsack () Unix::Statgrab - System Monitoring / 28
4 Introduction Audience Audience Developer who wants to create or improve monitoring software Developer who wants to evaluate system stats for content sensitive code paths Developer who wants to to learn the difference to earlier libstatgrab / Unix::Statgrab API Developers or Operators (Admins) who wants to learn about measurement of statistic values of the machine Prerequisites of the Audience Following knowledge is expected: advanced skills in at least one object oriented and procedural programming language more than one year practical experience in object oriented development Experience with Unix or compatible operating systems slightly above basic Perl experience Jens Rehsack () Unix::Statgrab - System Monitoring / 28
5 Introduction Motivation XS / C use of native API to get OS stats performance advantage interoperability (most VM s have a * native interface) portability - widest calling convention support in C Jens Rehsack () Unix::Statgrab - System Monitoring / 28
