CHAP 4.3 Performance Monitoring Flashcards
1
Q
monitoring parameters
A
- accessibility
- capacity
- performance
- security
2
Q
performance bottleneck areas
A
- processor
- memory
- disk
- network
3
Q
reasons for bottlenecks
A
- subsystems are insufficient
- a subsystem is incorrectly configured
- subsystems are not sharing workloads evenly and need to be balanced
4
Q
performance baselining
A
- helps to identify and resolve system bottlenecks
- used to watch for long term changes in usage patterns
5
Q
historical monitoring methods
A
- event viewer
- performance logs
6
Q
real time monitoring methods
A
- task manager
- performance monitor
- resource monitor
7
Q
what is task manager
A
helps to identify and resolve performance-related issues
8
Q
what is resource monitor
A
- provides an in-depth look at the real-time performance of server
- monitors performance of CPU, disk, network and memory (bottleneck areas)
- identifies and resolves resource conflicts and bottlenecks
9
Q
what is performance monitor
A
- used to examine how active programs affect a servers performance
- can also view historical data gathered through the use of data collector sets
10
Q
performance counters
A
processor - interrupts/sec
network interface - current bandwidth, output queue length, bytes total/sec
memory - pages/sec
11
Q
what are data collector sets
A
- enable you to gather performance-related and other system statistics for analysis
12
Q
types of data collector sets
A
- performance counters
- event trace data
- system configuration information
