Counters are organized into a three-level hierarchy:
|
object, counter, and instance.
|
|
|
An ______ is a component, application, or subsystem within an application. For example, Processor, Network Interface, and SQLServer: Databases are all these.
|
object
|
|
|
One or more _________ are specified within an object, and every object has to have at least one ________. For example, within the SQLServer: Databases object, you have ______ for active transactions, data file size,
transactions/sec, and the percent of the transaction log space currently in use. |
counters
counter counters |
|
|
A counter can have zero or more _____.
|
instances
|
|
|
To capture data for analysis, you need to configure a _____log, which runs in the background when no one is logged on to the machine
|
counter
|
|
|
Viewing counters in the graphical interface provided by System Monitor is useful only for looking at the _______state of a system. It is much more useful to capture ______ to a log to be used for later analysis.
|
immediate
counters |
|
|
When setting up counter logs, it is recommended that
you select counter objects instead of ________counters to ensure you have captured everything necessary for analysis |
individual
|
|
|
The default sample interval setting is every _______seconds and is the most common setting for routine analysis, establishing a baseline, and for long-term trend analysis

|
|
Failure to define a specific _______ is the most common cause of a counter log failing to start.
|
account
|
|
|
The second most common causes of a counter log failing to start are _________ or a ________ account
|
password expiration
locked out |
|
|
When the ______, ________, or _______ becomes overwhelmed with activity, processes need to wait for resources to be freed up
|
processor
network interface disk |
|
|
a processor queue length of eight indicates that there is insufficient ____________ on the machine and that eight requests are waiting in a queue for a processor core to become available
|
processor capacity
|
|
|
Although the queue length can be greater than
zero for very short durations, having any queue length greater than zero on a routine or extended basis means that you have a ____________ that affects application performance |
hardware bottleneck
|
|
|
What are the items that you can capture data for with System Monitor?
|
You can capture objects, counters, and counter instances
|
|
|
What types of data can System Monitor capture?
|
System Monitor captures numeric data for performance counters that are defined for hardware or software components.
|
|
|
What are the three counters that, by themselves, indicate a system problem?
|
System: Processor Queue Length,
Network Interface: Output Queue Length Physical Disk: Avg. Disk Queue Length |
|
|
__________ is used to capture numeric statistics about hardware and software components.
|
System Monitor
|
|
|
A counter object must have at least one ______.
|
counter
|
|
|
A counter can have zero or more ________.
