Figure 11-1
depicts the Task Manager.
|
|
|
2.
|
In the Task
Manager, the Application tab displays all programs currently running on the computer and the status
of those programs.
|
|
|
3.
|
In the Task
Manager, the Process tab shows all currently active processes with information about each, including
its Process ID number, CPU usage, CPU time, and Memory usage.
|
|
|
4.
|
System
Monitor is capable of a wide range of performance monitoring functions, including real-time
monitoring, recording logs for future examination, and generating performance threshold
alerts.
|
|
|
5.
|
You can use
the Performance tab in Task Manager to quickly ascertain whether a computer is performing
optimally.
|
|
|
6.
|
System
Monitor is used to monitor and record the same system measurements that Performance Monitor collected
for Windows NT 4.0 systems.
|
|
|
7.
|
Counters can
be read from the local system or any accessible system over a network.
|
|
|
8.
|
The
LogicalDisk: Disk Bytes/Transfer counter measures the average number of bytes transferred between
memory and disk during read and write operations.
|
|
|
9.
|
In general,
a smaller number in the LogicalDisk: Disk Bytes/Transfer indicates more efficient transfers than a
larger one.
|
|
|
10.
|
A page fault
occurs whenever a memory page is referenced that is not already loaded in RAM.
|
|
|
11.
|
Pathological
increases in Processor: Interrupts/sec occur when a malfunctioning device begins to generate false
interrupts or when excessive network traffic overwhelms a network adapter.
|
|
|
12.
|
Trace logs
differ from counter data logs in that they measure data continually rather than take periodic
samples.
|
|
|
13.
|
Trace Logs
allow you to define exactly which counters are recorded.
|
|
|
14.
|
Counter Logs
record nonconfigurable data from a designated provider when an event occurs.
|
|
|
15.
|
Trace Logs
are operating system environment status dumps that are more like a memory dump in the event of a STOP
error than a log of performance statistics.
|
|
|
16.
|
Once you've
recorded a log file, it can be used in System Monitor.
|
|
|
17.
|
The Counter
log will not record data when the Performance tool is closed.
|
|
|
18.
|
Counter logs
record data by taking measurements at random intervals.
|
|
|
19.
|
You can
terminate a log manually, or set termination to occur after a specified length of time, at a
specified time, or when the file is full.
|
|
|
20.
|
Once you
define a Counter log, you can either wait for the defined start time or issue the Start command from
the Action menu to begin recording data.
|
|
|
21.
|
An Alert
object can consist of one or more counter/instance-based alert definitions.
|
|
|
22.
|
The
individual alert definitions within an Alert object share the same sample interval, action triggers,
and start/stop settings, but operate as distinct alert events.
|
|
|
23.
|
An alert
definition focuses on one or all counters of one or all objects on the local or networked
computer.
|
|
|
24.
|
Each alert
definition is assigned a threshold and told whether to issue an alert when the measured value is
under or over that threshold.
|
|
|
25.
|
An Alert
event is triggered only when the measured value of the specific counter at the time of alert sampling
has crossed the threshold.
|
|
|
26.
|
Counter
levels between samplings have an effect on alerts.
|
|
|
27.
|
All event
log entries include the event's date and time, source, category, an event number, the name of the
account that generated the event, and the name of the computer on which the event
occurred.
|
|
|
28.
|
The
Scheduling tab of an Alert event's Properties dialog box is much the same as that of a Counter
log.
|
|
|
29.
|
A process is
any activity that causes an event detail to be created in one of the logs of the Event
Viewer.
|
|
|
30.
|
There are
two types of System and Application log events and three types of Security log records that are
recorded in Event Viewer.
|
|
|
31.
|
The System
log is the primary log file for most system services, drivers, and processes.
|
|
|
32.
|
The Security
log automatically tracks events.
|
|
|
33.
|
You can
optimize general system performance by indicating whether the computer is used primarily for
user-interactive applications or as a host for network services.
|
|
|
34.
|
The
Application log contains event messages that can be generated by Windows 2000 native applications or
services.
|
|
|
35.
|
Bottlenecks
will always exist in any computer.
|
|
|
36.
|
Disk
bottlenecks are the most likely problem when disk-related counters increase more dramatically than
other counters, compared to your baseline, or when queue lengths become unacceptably
long.
|
|
|
37.
|
You can
execute the diskperf command from a command prompt only.
|
|
|
38.
|
Software can
contribute to disk bottlenecks, often because of poor design, configuration settings that affect disk
performance, or outdated drivers.
|
|
|
39.
|
For
processors, the combination of high utilization and overlong queues is more often an indication of
trouble than is an occasionally high utilization rate.
|
|
|
40.
|
It's
important to recognize that performance scales arithmetically as additional CPUs are
added.
|
|
|
41.
|
Network
bottlenecks are not typical on most Windows 2000 machines.
|
