Basic Flow

Gathering data Analyzing data Monitoring dataFTP HTTP

Agent Layer Analysis Layer Web Interface Layer

• Gather raw data from monitoring target server

• Using SHELL script

(ex. ksh, perl, awk…)

• Basic monitoring items are from Tivoli

• User can add an optional items

• Polling time : 15 minute (change available)

• Transfer raw data from target servers by FTP

• Save raw data to archive directory

• Analyzing data using batch or CGI program

• CGI : perl *

• Graph : gd library * *

• Data archive : rrdtool * * *

• All of monitoring data and report are provided using Web-interface

• Server admin, DBA, operator and customer can use SDM

• Only web browser needed

• Notification (alarm, mail…)

• Auto generating report

Characteristic

• Simple Configuration SDM is developed by USF member to overcome Tivoli’s complexity and include essential fun

ctions for USF management

• Easy Customization All modules in SDM are SHELL scripts, ksh, perl, awk, so it is very easy to modify and custo

mize program

• Auto generated Reports All regular reports(monthly) are generated without manual operation, and real-time reports are

available for customer

• Integrated Web Console All monitoring items are integrated to only one web page so that admin and operators can reco

gnize evnets easily and fastly

• Lower Resource consume SDM consume lower server resource to monitor because SDM is minimized to essential functi

ons
