Measures reported by IBMWLPConPolTest
This test auto-discovers the connection pools on the target IBM WebSphere Liberty server and for each connection pool, this test reports the rate at which connections were created. This test also reports the rate at which connections were destroyed and the average time taken for a connection to be granted from each connection pool. Using this test, administrators can figure out the connection pool that is busy and the connection pool on which maximum number of requests were created.
Outputs of the test : One set of results for every connection pool on the target IBM WebSphere Liberty server being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| createCount |
Indicates the rate at which connections were created in this connection pool. |
Connections/Sec |
This measure is a good indicator of load on each connection pool.
Compare the value of this measure across connection pools to figure out the connection pool on which maximum number of connections were created. |
| destoryCount |
Indicates the rate at which connections were destroyed in this connection pool. |
Connections/Sec |
|
| managedConnectionCount |
Indicates the number of managed connection objects that were in use in this connection pool. |
Number |
|
| waitTime |
Indicates the average waiting time until a connection from this connection pool was granted. |
Milliseconds |
A low value is desired for this measure.
Compare the value of this measure across the connection pools to figure out the connection pool that takes too long to grant a connection i.e., in other words you can figure out the connection pool that is too busy to grant a connection. |
| connectionHandleCount |
Indicates the number of connection objects that were handled by this connection pool. |
Number |
|
| freeConnectionCount |
Indicates the number of connections that were available for use in this connection pool. |
Number |
A high value is desired for this measure.
A sudden/gradual decrease in the value of this measure indicates that the connection pool is busy. If too many connection requests are received continuously to this connection pool, then administrators may try increasing the number of connections in the connection pool. |
