Measures reported by PgConnectionTest
This test monitors the users who are currently connected to the server and reports the number and state of each user connection. Using the metrics reported by this test, administrators can promptly isolate idle and waiting connections, which are a drain on a server's resources. The measures
made by this test are as follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Total_connection |
The total number of connections that are currently established by this user on the server. |
Number |
|
| Idle_connection |
The number of connections of this user that are currently idle on this server. |
Number |
Ideally, the value of this measure should be low. A high value is indicative of a large number of idle connections, which in turn causes unnecessary consumption of critical server resources. Idle connections also unnecessarily lock new connections from the connection pool, thereby denying other users access to the server for performing important tasks.
Use the detailed diagnosis of this measure to view the details of the idle connections. |
| Active_connection |
The number of connections of this user that are currently active on this server. |
Number |
Use the detailed diagnosis of this measure to view the details of the active connections. |
| Waiting_connection |
Indicates the number of connections of this user that are currently waiting for a resource/database object/ lock to be released. |
Number |
The value of this measure should be kept at a minimum, as waiting connections also cause a resource drain.
Use the detailed diagnosis of this measure to view the details of the waiting connections. |
