  1. Chapter 10 System Monitoring • Issues • Performance Benchmarks • NT Server Services • Users and Server Access Information • Task Manager for Applications • Ram and Virtual Memory • CPU and Disk Resources • Performance • Event Logs

  2. Monitoring Issues • Start and Stop • Number of logged on users • Applications in use • Virtual memory settings • RAM management • CPU load • Disk response

  3. Performance Benchmarks • Statistics on CPU, disk, memory, I/O with no user • Use performance for slow, peak, average • Slow, peak, average for a new software • Benchmarks for growth (user and application)

  4. NT Server Services - I • Alerter (Messenger, Workstation) • ClipBook (Network DDE) • Computer Browser (Server, Workstation) • Directory Replicator (Server, Workstation) • EventLog • Messenger (Server, Workstation) • Net Logon (Server, Workstation)

  5. NT Server Services - II • Network DDE (dynamic data exchange) (Network DDE DSDM) • Network DDE DSDM (conversion of data object) • NT LM Security Support Provider (remote) • Remote Procedure Call Locator • Remote Procedure Call • Schedule

  6. NT Server Services - III • Schedule • Server • Spooler (printer) • UPS • Workstation

  7. Server Service • Control Panel • Service icon • Notes: • Started, paused, blank-not used • Continue button to restart a paused service • Startup button to set the start manual or auto • HW Profiles button to enable or disable a service for a given hardware

  8. Users and Server Access Information - I • Control Panel • Server icon • Notes: • Sessions • Open files • File locks • Named Pipes

  9. Users and Server Access Information - II • User button • Share button • In Use button • Replication button • Alerts button

  10. Task Manager for Applications- I • Ctrl+Alt+Del while logged on as Administrator • Task Manager • Application tab • End Task button • Switch button • New Task button

  11. Task Manager for Applications- II • Processes tab • Name of process • Process ID (PID) • CPU time used • Memory used

  12. Task Manager for Applications- III • Performance tab • Handles (no. of objects or files) • Thread (no. of code blocks executing) • Kernel memory (RAM used by OS) • Physical memory (RAM in server) • Commit memory (in use)

  13. RAM and Virtual Memory • Virtual memory • Page file • Virtual memory = RAM+12 MB • Example • Control Panel • System icon • Performance tab • Change button • Enter the min and max (min*1.25)

  14. CPU AND Disk Resources • Warning CPU 90% and disk 80%

  15. Performance Monitor - I • Administrative Tools menu • Plus button (for Add to Chart dialog box) • Counters • % DPC Time • % Interrupt Time • % Privileged Time • % Processor Time • % User Time • Interrupts/sec

  16. Performance Monitor - II • Explain button • Add button • Done button (view Performance Monitor graph)

  17. Event Logs - I • Administrative Tools menu • Event Logs • Error (stop sign) or warning (I) icon • Date and time • Source of the event • Category or type of event • Event no. • User • Name of computer

  18. Event Logs - II • Types of Event Logs • System • Security • Application

  19. Event Logs - III • Example: • My Computer • Public folder • File menu • Properties • Security tab • Auditing button • Check audit subdirectories and files
