Monitoring and Managing Server Performance

Server Monitoring To become familiar with the

server’s performance – typical behavior

Prevent problems before they occur

Diagnose existing problems or resource shortage

Benchmarks or baselines Normal server characteristics/patterns to

diagnose problems and identify components to be upgraded

Acquired by generating statistics about the system during no user activity periods and during normal activity periods, as well as during slow, average and peak periods

Gather benchmarks, and then frequently monitor server performance

Provide a basis for comparing data collected during problem situations with data showing normal performance conditions

Sample benchmarks Test benchmarks of disk, CPU, memory, and

network response before releasing a new operating system, server hardware, or a complex application to users

Slow, typical, and heavy usage of disk, CPU, memory, and other server resources for each server, combined network and server resources

Growth of use of network and server resources at specific intervals, such as every six months to a year

Accessing Server Services You can access server services through

Server Manager or the Computer Management tool

Check the status of running services Start, stop, pause and restart services Check service dependencies

Windows Task Manager To monitor processes/applications To view CPU/memory/networking

stats To view logged on users

Performance Monitor Objects, instances, counters Monitor in real-time or log in files Processor, Memory, PhysicalDisk,

Logical Disk objects and counters – meaning and troubleshooting

Performance Logs and Alerts Allows you to record information

for later use/analysis Counter and Trace Logs Allows you to setup alerts for

certain conditions.

Implementing the SNMP Service

Used for network management on TCP/IP-based networks

Provides administrators with a way of centrally managing workstations, servers, hubs, and routers from a central computer running management software

SNMP can be used for the following: Configuring network devices Monitoring the performance of a network Locating network problems Monitoring network usage

11

Implementing the SNMP Service (continued)

SNMP provides network management services through agents and management systems

SNMP management system (a computer running management software) Sends and requests information from an

SNMP agent SNMP agent (any computer or network device

running SNMP agent software) Responds to the management system’s

request for information
