We thank our customers
for sharing their views on server
performance problems
Over 100 survey participants

6. Survey – Categories and Concerns
6
1. Inventory and Mapping
– Physical location of the server
– List of servers and their hardware & software configuration details
– Connected switch ports information
2. Server Resources crunch
– Hard Disk
– CPU and Memory crunch
– Network I/O
3. Hardware health & environment issues
– Server hardware failures
– Temperature and humidity in a Data-Center.
– UPS health

7. Survey – Categories and Concerns
7
4. Service Availability and SLA Management
– Unstable application services or poor performance of application
components
– DNS/ DHCP conflicts
– Multi-tier service level visibility
5. Capacity Management
– Optimum utilization of server to reduce the floor space and power
consumption (Green IT)
– Virtualization management hiccups
– Server utilization trending
6. Security Threats
– Vulnerability assessment
– Service Packs/ Patch deployment
– Log Analysis
– Compliance reporting

9. Server Performance Problems
9
Hard Disk Drive
#1
Data intensive applications or services, viz., File servers,
Database servers.
Problems
– Sudden increase in logs like transaction logs,
application logs, error logs
– Unsolicited operations
– Disk running out of space than intended
– Hard Disk aging factor
– Increasing bad sectors and data loss

What to do!
– Configure log roll-overs
– Avoid unwarranted operations – Schedule it for non-
business hours
– Routine disk defragmentation
– RAID

11. Server Performance Problems
11
Hard Disk Drive
#1
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

12. Server Performance Problems
CPU & Memory
#2
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

13. Server Performance Problems
CPU & Memory
#2
What to do!
– Tweak CPU priority/ affinity
– Increase Application’s memory cache
– Fine-tune virtual memory
– Add more memory
– Clustering/ Load balancing
– Server Virtualization

14. Server Performance Problems
CPU & Memory
#2
What to look for:
CPU performance metrics
– Current CPU utilization
– % Processor time & Processor Queue
– Deferred Procedure Calls Queues & Interrupts/ Sec.
Memory performance metrics
– Current Memory Utilization or Free Memory
– Page/ Sec. (Faults, Writes, Input, Output)
– Cache Bytes, Peak and Faults/ Sec
– Number of processes and their CPU/ Memory usage

15. Server Performance Problems
Server Temperature
& Power#3
Could happen to any server
Problems
– Improper/ Failure of cooling system
– Diminishing FAN speed or FAN breakdown
– Power outages due to faulty PDU/ SMPS
– Poor server performance followed by application
sluggishness
– Frequent server crash
– UPS Low battery/ Poor generator health

16. Server Performance Problems
Server Temperature
& Power#3
Use case

17. Server Performance Problems
#3 Server Temperature
& Power
What to look for:
Vendor specific metrics
– FAN Speed
– Server Temperature
– System Event Logs/ BIOS System logs/ SNMP Traps
– Input/ Output voltage
– Monitoring cooling units and temperature sensors for
current room temperature
– Automated UPS and Generators health monitoring

18. Server Performance Problems
Network Interface
bottlenecks#4
Problems
– Impulsive bandwidth
– Could be a virus attack or spamming
– Excessive Error/ Discard rate
– Packet collision
– Intermittent network connectivity and poor
application/ service performance
– Bad Network Interface Card/ Cable disconnected
– Equivalent to device outage

19. Server Performance Problems
Network Interface
bottlenecks#4
Use case

20. Server Performance Problems
Network Interface
bottlenecks#4
What to look for:
Network Performance counters
– Received or Transmitted Bytes per sec
– Bandwidth Utilization
– Packets Received or Transmitted per sec
Check Event Logs/ Syslogs
Network Connectivity
– Try replacing the cables/ NIC
– Check the corresponding switch port performance

21. Server Performance Problems
Virtualization
Management#5
Problems
– Poor application consolidation - Over/ Under
provisioning
– Applications starve for resources
– Unplanned outages or poor business service
performance
– Ad hoc virtual machine management & failure to
identify security lapses
– Complexity in managing both physical and virtual
servers

22. Server Performance Problems
Virtualization
Management#5
What to look for:
Application consolidation
– Total usage of CPU, Memory and Network has to be
considered
– Verify the nature of data and the security needed
Virtual machines per host count
– Syslog and regular virtual machines inventory checks
Integrated common set of tools
– For monitoring and managing both physical and virtual
infrastructure
