Measures reported by SqlAzuQryWaitTest
Any performance degradation or unavailability of the database servers can severely impact the performance of the entire service, often causing customer dissatisfaction and lost business revenue. Continuous monitoring of the SQL Azure database servers are hence imperative. This can be easily done using the SqlAzuQryWaitTest.
This test monitors the wait types on the SQL Azure server, and reports the number and duration of waits of each type.
Outputs of the test : One set of results for the SQL Azure server being monitored
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| No_of_wait_type |
Indicates the total number of waits for this wait type. |
Number |
The detailed diagnosis of this measure provides the query that caused the waits; you may want to fine-tune the queries to reduce the number of waits. |
| Avg_of_wait_time |
Indicates the average wait time for this wait type. |
Seconds |
Ideally, the value for this measure should be low. If the value for this measure is high, use the detailed diagnosis of the Num of waits measure to identify the queries that are causing the waits to remain for a long time. You may want to fine-tune the queries to reduce wait time. |
| Max_of_wait_time |
Indicates the maximum wait time for this wait type. |
Seconds |
Comparing the value of this measure across wait types will enable you to accurately isolate the wait type that is responsible for the longest waits. |
