Proposal for an Automated System

Proposal for an Automated System III. PROPOSED SYSTEM All traditional frameworks do not discuss functional requirements or, explicitly automatable parts of ITSM processes. Automation is identified as one of the approach to tackle the challenges of current service management processes. The architecture of the system is shown below in Figure 1: Figure 1. Block Diagram for the Architecture As shown in the figure above, the architecture consists of three main blocks i.e., ITSM Server, Secondly the Knowledge server and finally the configuration Management logic for triggering the actions. Firstly an incident does gets created or submit in the iTop Server with respect to the client request. Then there is a constant polling for the current status of the incident. As the status for the given incident does have three stages i.e. New, Assigned, Closed. Subsequently, for the given new Incident the status gets changed to Assigned when the based on which an Issue also gets created in the Knowledge server. For the given Incident Id an AP Issue Id also gets created in the Knowledge server for which the status is also polled back to the ITSM server in the Public logs with respect to the given incident. Once an issue and issue id gets created within the knowledge Server based on the issue type specific knowledge Item gets triggered. KIs are the considered to be a simple rule with context written in xml format which does have an Issue condition tag which gets cross checked with respect to the given incident. Based on the issue conditions corrective actions are taken to resolve the issue which is mentioned in the command tag for the respective KI. Subsequently, the triggering actions given by the KI are been executed by the configuration management tool. After the successful execution of the actions the issue gets closed for which the status is again polled back to the ITSM server and the related incident status also gets changed to close. The MARS model basically defines the environment in which the KS (Autopilot) runs. With the help of this model the environment gone under excessive changes can be automated easily and quickly. It illustrates the interdependencies of application, resource, software and Machine. With this model, the IT landscape of a given company can be mapped to both a technical and business perspective. Here application and resource maps to the business relevant and organizational parts of IT operations whereas the software and the machine refers to the technical side of the IT operations. Hence, it allows us to optimize the IT environment based on a lightweight and reusable model which could the basis for automated IT operations i.e., services. It can also be used to create the CI’s (Configuration Items). IV. MATHEMATICAL MODEL The system can be modeled mathematically given below. Let, â€Å"S† be a proposed system such that, S = {s, E, X, Y, FS, DD, NDD †¦| ÃŽ ¦} s = Starting point = R->ITSs Where CR = Set of client requests ITSMs = IT Service Management Server E = Ending Point = The given incident in terms of issue is solved X = Input to the system Set of Incidents (I) = {I1, I2, I3 , †¦.} Y = For the Given incident an issue in created in KS; I->KS Where KS =Knowledge Server Deterministic Data (DD): Given Incident is already resolved. Non-Deterministic Data (NDD): for the given incident there is no solution. Success = Issue created in the KS in successfully solved. = In-> rn Where, In is Incident created r1 is desired result for rn. Failure = Failure in execution of user request Conditions: -Insufficient input request and not valid user. V. EXPERIMENTAL SETUP The experimental setup for proposed system will be building an ITSM infrastructure and a Knowledge Server using built on Linux based machine using ITSM tool iTop. The ITSM Infrastructure would be having a Linux Machine Node on which ITSM tool iTop is been installed. Then we need to setup other Machine node i.e., for the implementation of the DS (Delivery Integration) where the deployment for the implemented code will be done. Third is the knowledge server i.e., another Linux Machine Node for the automation tool is required and the for configuration management. The particulars about platform and technology used are mentioned as follows: Base Operating System: Linux Based Machine server (Centos 6.5+ 64bit Preferred) Technology: iTop For ITSM server ,Version 2.1.0 Arago AutoPilot, Version 5.1 Ansible 1.7.2 / Chef. (Open Source). Databases: iTop Backend MySQL. Language: Java JDK 1.7. Java Tool: Eclipse JEE Other Dependencies: Maven3,Apache2,Tomcat7, REST APIs, Shell Scripting, and XML for Knowledge Items, MARS model. According to above specifications and structure, the proposed system is built up. VII. CONCLUSION Unlike other automation solutions, Knowledge based automation can deal with high levels of incorrectness and inaccuracy and only uses the given input as an entry point, or considers as a general universe description. Using this automation technology we try to enhance the power of IT configuration management process which is quite critical for our business processes. Our approach could also serve as input for discussing a reference model for the design of management services that could help tool vendors to create interoperable Management tools by enabling service-oriented access to specific tools functionality.
