Monitor Server Memory

Monitor server memory to determine whether any ofthe following conditions exit

Memory bottlenecks

Insufficient memory

Excessive paging

Memory Leaks


4/36


Identify and Resolve Memory Bottlenecks

MEMORY COUNTER ACCEPTABLE AVERAE RANGE DESIRED VALUE ACTION

Pages/Sec 0-20 Low Find the process that is causing paging Add RAM

Available Bytes Minimun of 5% of total memory High Find the process that is using RAM. Add RAM

Committed Bytes Less than physical memory Low Find the process that is using RAM. Add RAM

Pool Nonpaged Bytes Remain steady, no increase Not applicable Check for memory leak in applicat ion

Page Faults/Sec Below 5 Low Find the process that is causing paging Add RAM

Identify and Resolve Processor Bottlenecks

PROCESSOR COUNTER ACCEPTABLE AVERAGE RANGE DESIRED VALUE ACTION

%Processor Time Less than 85% Low Find process using excessive processor

time. Upgrade or add another processor.

System:Processor Queue Less than 10% Low Upgrade or add additional processor

Length

Server Work Queues: Less than four Low Find process using excessive processor

Queue Length time. Upgrade or add another processor.Interrupts/Sec Depends on processor Low Find controller card generating interrupts

Procedure: To open Performance, clic start-control panel-

administrative tools and then performance

In the performance window, System Monitor is

selected by default. In the right pane of System

Mointor, the % processor Time counter is displayed

Monitoring Disks

Presence of disk bottlenecks Need for disk defragmentation

Need for additional or faster disks

Presence of excessive paging Disk efficiency

Identify and Resolve Disk Bottlenecks

PHYSICAL DISK COUNTER ACCEPTABLE AVERAGE RANGE DESIRED VALUE

% Disk Time Under 50% Low

Current Disk Queue Length 0-2 Low

Avg. Disk Bytes/Transfer Baseline or higher HighDisk Bytes/Sec Baseline or higher High

Monitor Disks

Procedure Click start-control panel-administrative tolls and

Performance

Right click in the right pane of System Mointor, and

then lic Add Counters In the Add Counters dialogbox, uder Performance

object, select Physical disk, select the options andclick Add.

Monitoring Network Usage Percentage of network bandwidth in use on the

segment beging mointored.

Monitoring network usage helps you detect network

bottlenecks

Bottlenecks in network communication directly affectthe experence of the user at the client workstation and

the entire network

Typical causes of network bottlenecks are:

-- Overloaded Server

-- Overloaded network

-- Loss of network integrity


29/36


Identify and Resolve Network Bottlenecks

NETWORK INTERFACE COUNTER ACCEPTABLE AVERAGE RANGE DESIRED VALUE

Network Utilization(in Task Mamager) Generally lower than 30% Low

Network Interface: Bytes Sent/Sec Baseline or higher High

Network Interface:Bytes Total/Sec Baseline or Higher High

Server:Bytes Received/Sec Less than 50% of the capacity of the bandwidth of the NA

network card
