Measurement
Unit |
Interpretation |
| AvgCpuTime |
Indicates
the average cpu time consumed by the transactions to this database.
|
MillSec |
Ideally, this value should be low. If the value is high, then use the detailed diagnosis of this measure to view the top transactions in terms of CPU consumption. Such transactions can then be fine-tuned, so that they are more resource-efficient.
|
MaxCpuTime |
Indicates the maximum CPU time of transactions to this database.
|
MillSec |
|
AvgLogicalReads |
Indicates the average number of logical reads performed by the transactions to this database.
|
number |
Use the detailed diagnosis of this measure to view the complete details of transactions causing logical reads to occur on the database.
|
MaxLogicalReads |
Indicates the maximum number of logical reads performed by transactions to this databases
|
number |
|
AvgPhysicalReads |
Indicates the average number of physical reads performed by transactions to this database.
|
number |
Physical database reads can cause processing overheads to escalate, thereby affecting database performance. These transactions therefore have to be minimized.
If the value of this measure is very high, then use the detailed diagnosis of this measure to view the details of the transactions that are causing physical reads to occur.
|
MaxPhysicalReads |
Indicates the maximum number of physical reads performed by transactions to this database.
|
number |
|
AvgPageModified |
Indicates the average number of pages modified by transactions to this database.
|
number |
Use the detailed diagnosis of this measure to view the details of transactions that are modifying pages.
|
MaxPageModified |
Indicates the maximum number pages modified by transactions to this database.
|
number |
|
AvgLongWaited |
Indicates the average execution time of transactions that have taken too long to execute.
|
Millsec |
If the value of this measure is high, it could indicate that one/more inefficient queries are executing on this database. You might then have to use the detailed diagnosis of the measure to view the top transactions in terms of execution time, and identify that transaction that has taken the longest to execute. Fine-tune the transaction to prevent database slowdowns."
|
MaxLongWaited |
Indicates the maximum number of times transactions waited in a database.
