SBLIM: creating a set of providers from scratch


The SBLIM (Standards Based Linux Instrumentation for Manageability) is an open source project whose objectives are to ease the administration of GNU/Linux systems. The main idea is to provide a basis to allow GNU/Linux to be managed by means of WBEM (Web Based Enterprise Management). This basis is composed of a collection of programming interfaces, providers, client applications and development tools. WBEM is a set of standards defined by DMTF to unify the management of distributed computer systems. The goals of this tutorial is to provide the audience with a "build it from scratch" session using a very simple system management task as example (probably ntp). The session includes implementing live the following steps: * Designing the CIM data model for this example * Coding the Resource access layer (which actually accesses the data) * Coding the Common Manageability Provider Interface layer (which transforms the raw data from the previous layer to the CIM standards and vice-versa) * Coding the Business Logic layer (which gets CIM data from the cimserver as an http request using xml and stores it in whichever manner the developer needs and vice-versa) * Coding the Presentation Logic Layer (This is the GUI. It gets and sends data from/to the above layer) In order to keep this description clean, please refer to [1] to better understand each of the above layers. The author is one of the developers of the SBLIM project. Note: The author has also submitted a seminar proposal on SBLIM (SBLIM: Standards Based Linux Instrumentation for Manageability). Please, also refer to it when analyzing this tutorial proposal. References: [1] Links: - SBLIM: - WBEM: - CIM standards:
