Hive Query Statistics Test
The efficiency of the Apache Hive service can be measured by the quality of the queries. By periodically checking the feedback returned by the data query engine, administrators can determine the number of queries that may have to be optimized before being executed. The Hive Query Statistics test helps administrators perform this check at regular intervals. With the help of the metrics reported by this test, administrators can quickly figure out the number of queries that succeeded and the queries that failed.
Target of the test : Apache Hive
Agent deploying the test : An internal/remote agent
Outputs of the test : One set of results for each Query Statistics:total/active queries to the target Apache Hive.
Parameter | Description |
---|---|
Test period |
How often should the test be executed. |
Host |
The IP address of the target server that is being monitored. |
Port |
The port number through which the Apache Hive communicates. The default port is 10002. |
SSL |
By default, the SSL flag is set to False, indicating that the target Apache Hive is not SSL-enabled by default. To enable the test to connect to an SSL-enabled Apache Hive, set the SSL flag to True. |
DD Frequency |
Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time the test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Succeeded queries |
Indicates the number of total/active queries that succeeded. |
Number |
A very high value is desired for this measure. |
Failed queries |
Indicates the number of total/active queries that failed. |
Number |
Ideally, the value of this measure should be 0. A non-zero value could indicate that one/more queries have failed. |
Compiling queries |
Indicates the number of total/active compiling queries. |
Number |
|
Executing queries |
Indicates the number of total/active executing queries. |
Number |
A very high value is desired for this measure. |
Submitted queries |
Indicates the number of total/active submitted queries. |
Number |
|
Waiting compile ops |
Indicates the number of total/active queries waiting for compilation. |
Number |
Ideally, the value of this measure should be 0. |
