Measures reported by HiveServer2AsynTest
To optimize the performance and at the same time to support concurrent accesses from users, the Apache Hive data warehouse uses asynchronous thread pools. It is critical to monitor thread pools in a data warehouse on an ongoing basis. This test does just that.
Outputs of the test: One set of results for the target Apache Hive
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| plSize |
Indicates the size of asynchronous thread pool. |
Bytes |
If the pool size is high and the number of active threads is low, it signifies that the threads are not being destroyed immediately after use.
|
| queSize |
Indicates the size of the asynchronous operation queue. |
Number |
Ideally, a low value is desired for this measure.
An unusually high value of this measure is indicative of any problem with the corresponding queue or its end points.
