1. What is SDM? SDM : Server and Database Monitoring  SDM is the web-based real-time server and database monitoring and reporting tool  Service Items Server Resource Reporting Server Monitoring Database Monitoring Resource Simulating TSD Reporting (problem)

2. Architecture Customer Web Layer Customer DB Layer Transfer data using FTP Gathering Data using SHELL SDM Server Server : Linux, Web: Apache DB : rrdtool CGI : Perl5 Analysis Module : Shell, CGI Web Server (Server Resource Report) Operator Customer InternetUSF Transfer data using FTP Real Time Server Resource & Database Monitor httpd

3. Basic Flow Gathering dataAnalyzing dataMonitoring data FTPHTTP Agent LayerAnalysis LayerWeb 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

4. Characteristic Simple Configuration  SDM is developed by USF member to overcome Tivoli’s complexity and include essential functions for USF management Easy Customization  All modules in SDM are SHELL scripts, ksh, perl, awk, so it is very easy to modify and customize 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 recognize evnets easily and fastly Lower Resource consume  SDM consume lower server resource to monitor because SDM is minimized to essential functions

5. Feature1 Server Resource Reporting Report Type  Real time : daily, weekly, monthly, yearly  Regular : Monthly Resource Report for each customer Report Items  CPU Activity, Free Memory, Virtual Memory, Page in VM, Run Queue Size, Total Disk Usage, Disk IO stat Special features  Auto Comment : basic comments are served in all reports  Archive : user can save any report to review it later  Registration : easy register new customer and server  Authentication : username/password required  Available OS : AIX, Solaris, Windows 2000

6. Weekly CPU Activity Graph Monthly Regular Report for Customer

7. Monitoring Items  Load Average : run queue size  CPU Usage : % of user call, system call, wait and idle  Disk Usage : each file system disk usage  I-Node Usage : each file system I-node usage  Swap space Usage : swap space usage  Page out count : page out count  Daemon Status : cron, inetd, syslogd, sysdog, esmd, dsmc process check Special features  Red alarm (fatal), Black alarm (critical), Blue alarm (harmless), Green alarm (normal)  Notification : screen, sound(ring), mail (if mail server available)  Top 10 process : Top 10 CPU consumer process list available for each server  Popup information : all item has popup to provide detailed information  Change thresholds : admin can change threshold value to confront various situations  Available OS : AIX, Solaris, Windows 2000 Feature2 Server Monitoring

8. Server Monitoring Console Top 10 Process Popup Window

9. Monitoring Item Special features  Red alarm (fatal), Black alarm (critical), Blue alarm (harmless), Green alarm (normal)  Notification : screen, sound(ring), mail (if mail server available)  Popup information : all item has popup to provide detailed information  Change thresholds : admin can change threshold value to confront various situations Feature3 Database Monitoring DB2Oracle Items UP/DOWN Lock : lock timeout, lock list space, lock escalation, rollback due to dead lock Hit ratio : package, catalog, data, index Logging mode Tablespace usage : SMS, DMS UP/DOWN SGA : total, buffer cache Hit ratio : buffer, dictionary, library Session : total count, active session, wait Rollback wait Tablespace : usage, FSFI, allocation error Log check : alert_*.log UtilityDb2SQL*Plus

10. Database Monitoring Console Alert log check Popup Window

11. What is Resource Simulating?  Sometimes, need to show previous monitoring data like a real-time monitoring console ( for example; when you want to show previous night problem status)  You can select Date, hour, minute (interval 15 minutes) Speed : slow, normal, fast, very fast Special features  Monitoring items : Same to server monitoring  PAUSE/CONTINUE : you can pause simulation and continue  STOP : you can stop simulate  Any time you want to see Feature4 Resource Simulating

12. Choose Date to simulate Simulate Monitoring

13. Problem reports from TSD Database  Daily Report : problem list generated from yesterday  Weekly Report : for problem meeting  Monthly Report : for problem analysis  Search Problem : investigate problem by keyword Special features  Web-based report : overcome TSD’s weak point; reporting  Print Format : print format available  Easy Customizing : only SQL statement using Perl and DBI  Graphical Interface Feature5 TSD Reporting

14. Daily Problem Report Weekly Problem Report

15. Server/Software for SDM Server Requirement  Target Servers: No restriction (AIX, Solaris, W2k)  Analysis Server : No restriction (Linux, Unix) Software  Target Server ksh, awk, perl5  Analysis Server gd library zlib rrdtool : v1.0.28 Perl 5 : DBI, DBD for DB2, DBD for Oracle
