MySQL Cluster User Activity Test
This test reports the number and state of the processes of each user who is currently connected to each node on the target MySQL Cluster database server. Using the metrics reported by this test, administrators can promptly isolate idle processes, which are a drain on a server’s resources.
Target of the test : A MySQL Cluster
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each user currently connected to each node on the target MySQL Cluster database server monitored
Parameter | Description |
---|---|
Test Period |
How often should the test be executed. |
Host |
The host for which the test is to be configured. |
Port |
The port at which the specified host listens. |
Database |
Specify the name of a database on the target MySQL Cluster database server being monitored |
Username and Password |
The eG agent has to be configured with the credentials of a user who has server-wide Process and Select privileges on the monitored MySQL Cluster database server. To know how to create such a user, refer to Pre-requisites for Monitoring the MySQL Cluster Database Server |
Confirm Password |
Confirm the password by retyping it here. |
Idle Time |
Specify the time duration (in seconds) above which the processes that are waiting in the database will be regarded as idle. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
