Maria Long Running Queries Test

This test tracks the currently executing queries on a Maria Database server and determines the number of queries that have been running for a long time. This test also tracks the maximum time taken to execute the queries. You can also use the detailed diagnosis of this test to drill down to the exact queries that have been running for an unreasonably long time, and thus isolate the resource-intensive queries to the database.

Target of the test : A Maria Database server

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the target Maria Database being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the Maria Database server.

Port

The port on which the server is listening

Database

Specify the name of the database that is to be monitored on the target Maria Database server

User 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 Maria Database server. To know how to create such a user, refer to Configuring the eG Agent with Access Privileges section.

Confirm Password

Confirm the password by retyping it here.

Elapsed Time

In the Elapsed Time text box, specify the duration (in seconds) beyond which a query should have executed for it to be regarded as a long running query. The default value is 10.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Long running queries

Indicates the number of queries currently executing on the database server that have been running for more time than the configured Elapsed Time.

Number

The detailed diagnosis for this measure indicates the exact queries and which user is executing the queries. This information can be very useful in identifying queries that may be candidates for optimization.

Maximum duration

Indicates the maximum duration taken to execute the queries.
