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.

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

Need to be taken care of

The format of the servers list file
Detailed Design

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



Name, Type, Timeout, Port, Check interval,
Notification.
Type includes http, ftp, ssh, tcp, smtp, pop3, mssql,
imap, tcp-connection.
Log message

"service_type on address:port up/down at
occuring_time“


For example: "ftp on yahoo:21 down at 1:30 afternoon".

Trace of Requirements to Design

Functional Requirements:

For Fundamental actions

Allows the validity checking when loading a servers IP
address list, if the format is not correct, an error
message will pop-up.


Check use case diagram above for exact sequence
of operations.


Finished the implementation
Finished the implementation
Use JAVA ICMP packages to get required results

Finished the implementation
Trace of Requirements to Design

Interface Requirements:


Input data items: Server IP address list
(including the Ip address, the server type,
the server port) ===> Implemented, see
the GUIs
Output data items

Statistical analysis in a period of time.


Finish the implementation
Error messages in the case of invalid data input

Will be implemented in the implementation phase.
