Maria Locks Test

This test monitors the locking activity of various transactions supported by a Maria Database server.

Target of the test : A Maria Database server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Maria Database server 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	Interpretation
Maximum read and write locks	Indicates the maximum number of read and write locks that can be held on the server.	Number
Total locks count	Indicates the total number of locks that are currently held on the server.	Number	A high value of this measure may indicate a contention for locks in the system, delayed execution of requests etc.
Read locks count	Indicates the number of locks that were held to read data from the database server.	Number
Write locks Count	Indicates the number of locks that were held to write data to the database server.	Number
Current read and write locks	Indicates the percentage of locks that were currently held to read from and write to the database server.	Percentage	A value close to 100% indicates that the maximum number of read and write locks that can be held on the server is reached. Try increasing the Maximum read and write locks measure to reduce the value of this measure.
