Maria Thread Statistics Test

This test tracks the Maria Database server threads and reports various performance statistics pertaining to them.

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 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.
SSL	This indicates that the eG agent will communicate with the Maria Database via HTTPS or not. By default, this flag is set to No, as the target Maria database is not SSL-enabled by default. If the target database is SSL-enabled, then set this flag to Yes.
Verify CA	If the eG agent is required to establish an encrypted connection with the target Maria Database server by authenticating the server's identity through verifying the server CA certificate, set Verify CA flag to Yes. By default, this flag is set to No.

Measurements made by the test
Measurement	Description	Measurement Unit
Total threads	Indicates the total number of threads that are currently running on the database server.	Number
Background threads	Indicates the number of background threads i.e., internal server threads that are currently executing on the database server.	Number
Foreground threads	Indicates the number of foreground threads i.e., user connection threads that are currently executing on the database server.	Number
Killing threads	Indicates the number of threads that kill other threads executing on the database server.	Number
Error threads	Indicates the number of threads that are error prone on the database server.	Number
Delayed insert threads	Indicates the number of threads that inserts the results of the INSERT DELAYED statements.	Number
Retrieve longdata thread	Indicates the number of threads that retrieve long data while executing prepared statements on the database server.	Number
Maximum duration thread	Indicates the maximum time taken for a thread to execute on the database server.	Seconds
