High Level Design Interface Diagram Interface Diagram

Use Case Diagram

High Level Design Design Issues - Design Issues - Reusability Some components may be designed to be reusable Maintainability Need to be taken care of Customer may want add new functions and new services type Detailed documentation.

High Level Design Design Issues - Design Issues - Portability Need to be taken care of The software needs to be run on different Operating System : Windows or Linux. Security Not important Does not contain sensitive information Only one user : Network Administrator

High Level Design Design Issues - Design Issues - Robustness Need to be taken care of The format of the servers list file

Detailed Design Operation Sequence Diagram Operation Sequence Diagram

Data Dictionary No.1 - Servers List Statement: it holds all the servers need to be monitored, including address, port, service type Source: Customer Operations: Create an empty one, load from a saved file, save to a file, edit Conflicts: When monitoring, no operation can be perform on servers list except reading Supporting Materials: Customer requirements, High-level design, Test plan Revision History: 1.0

Data Dictionary No.2 – Plug-in Notification Statement: It is method used to notify user in case of error Source: Monitoring result Operations: Enable, disable, configure, notification Conflicts: When configuring the plug-in notifications, the monitoring should be stopped and others buttons are not accessible Supporting Materials: Customer requirements, High-level design, Test plan Revision History: 1.0

Data Format Service Configuration Service Configuration Name, Type, Timeout, Port, Check interval, Notification. Name, Type, Timeout, Port, Check interval, Notification. Type includes http, ftp, ssh, tcp, smtp, pop3, mssql, imap, tcp-connection. Type includes http, ftp, ssh, tcp, smtp, pop3, mssql, imap, tcp-connection. Log message Log message "service_type on address:port up/down at occuring_time “ "service_type on address:port up/down at occuring_time “ For example: "ftp on yahoo:21 down at 1:30 afternoon". For example: "ftp on yahoo:21 down at 1:30 afternoon". Statistical chart Statistical chart Number of faults at each logging time Number of faults at each logging time
