Top 5 Server Performance Management problems
& How to resolve them using
OpManager
Agenda
– About ManageEngine– Survey inferences– Top 5 server performance problems
– Problem, outcome, and what to monitor
– How to resolve them using OpManager– Discussion
About ManageEngine

Survey Thanks
5
We thank our customersfor sharing their views on server
performance problems Over 100 survey participants
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
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

Server Performance Problems
9
Hard Disk Drive#1Data 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
Server Performance Problems
11
Hard Disk Drive#1What 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
Server Performance Problems
CPU & Memory#2Problems– 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
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
Server Performance Problems
CPU & Memory#2What 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
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
Server Performance Problems
Server Temperature & Power#3
Use case
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
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
Server Performance Problems
Network Interface bottlenecks#4
Use case
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/ SyslogsNetwork Connectivity– Try replacing the cables/ NIC– Check the corresponding switch port performance
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
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
