    • Unsolicited operations
      • Disk running out of space than intended
    • Hard Disk aging factor
      • Increasing bad sectors and data loss
    Hard Disk Drive #1
  • 10. Server Performance Problems
    • What to do!
    • Configure log roll-overs
    • Avoid unwarranted operations – Schedule it for non- business hours
    • Routine disk defragmentation
    • RAID
    Hard Disk Drive #1
  • 11. Server Performance Problems
    • What to look for:
    • Disk Space metrics
    • Available Free Space/ Used Disk space
    • Rate of increase in disk space utilization
    • Disk performance metrics
    • Disk Speed per second (Reads, Writes & Transfer)
    • Disk Bytes (Read, Write & Transfer)
    • Disk Queue Length (Average, Current, Read & Write)
    • System Event Logs/ Syslogs or SNMP Traps
    Hard Disk Drive #1
  • 12. Server Performance Problems
    • Problems
    • Troubled Application/ Service
    • Unnecessary processes running
      • Sudden spike in CPU/ Memory usage, leading to server crash
      • High service response time or unavailability
    • Defective hardware components
      • Unstable server
    CPU & Memory #2
  • 13. Server Performance Problems
    • What to do!
    • Tweak CPU priority/ affinity
    • Increase Application’s memory cache
