MySQL is an open-source relational database management system (RDBMS) based on Structured Query Language (SQL). While monitoring MySQL, the DBAs can:

  • Create custom SQL metrics and apply to the database.
  • Track and analyze the monitoring metrics.
  • Check the availability of the database.


  • Database and port(3306) can be accessed by the gateway.
  • serveradmin privilege to monitor the database. For more information, see Monitoring Privileges.
  • A gateway management profile mapped to a resource.
  • Create credentials with type as Database before assigning a template to a resource. The Port, Connection Time Out, and Is Secure values are not used while creating credentials.

Supported version

  • MySQL Server 2008 or higher.
  • Java Database Connectivity(JDBC): 8.0.17.

Database discovery and monitoring

The administrator can deploy an agent or gateway to support MySQL server agent-based or agentless monitoring respectively.

Discovery using an agent

The agent auto-discovers the MySQL database and collects the following metric information:

  • MySQL-Engine information
  • MySQL-Recommendations
  • MySQL-Database information
  • MySQL-Performance information
  • MySQL-Slave information
  • MySQL-Server information
  • MySQL-Variable information
  • MySQL-Status information
MySQL Dashboard

You can also apply agent-based templates to initiate monitoring.

Discovery using the gateway

The gateway establishes a connection to the database using Java Database Connectivity (JDBC) Java API and collects monitoring metrics using SQL queries. To monitor the MySQL database, install gateway version 5.0.0 or later.

Use one of the following mechanisms to discover MySQL servers to add them to your inventory:

  • WMI
  • SSH
  • SNMP

Optionally, add a database server manually to the infrastructure inventory.

To add a resource manually to the inventory:

  1. Select Infrastructure.
  2. Click the Settings > Resource > Add.
  3. From the Add Device window, provide the required details such as Device Type and Management Profile.
  4. Click Save.

Prepare the device to start monitoring

To monitor MySQL:

  1. Associate appropriate database credentials to the discovered database.
  2. Assign one or more database-specific global monitors or templates on the device.
    Optionally, create custom metrics or monitors using SQL queries and assign them to the database.

To track monitoring of MySQL database in your cloud environment, see Monitoring Cloud Database using Gateway.

Create custom metrics

To create a metric using SQL query for MySQL monitoring, navigate to Monitoring > Metrics > Create Metric. For example, to create a metric to check the active transactions use:

SELECT count(*) from performance_schema.events_transactions_current where state='ACTIVE'\n

For more information, see Manage Metrics.

Assign templates from setup

Assign MySQL templates to one or more resources for a selected client and modify the configuration parameters while assigning templates. For more information, see Assign Templates from Setup.

Assign templates at the device level

Applying MySQL templates at the device level helps you to assign one or more templates to a specific resource. You can change the configuration parameter default values while assigning the templates. For more information, see Assign Templates at the Device Level.

Template configuration parameters:

Configuration ParameterDescription
Connection Time OutThe maximum time to connect to the database. The driver waits for the specified time before timing out due to connection failure. The default time is 15000 milliseconds(ms).
Service Transport TypeTo configure the database at a secure end-point. The default type is In-secure. The connection is Secure when the data sent between the client and server is encrypted.
Service PortThe port number where the database is running. The connection is made to the specified port if you specify the port and the database name. The default port is 3306.
DB Instance NameThe name of the database to connect to. The default name is root.
  • If you have multiple database names with different ports, use the following syntax: `DBname1:Port1, DBname2:Port2,..` (Comma-separated).
    Important! Create separate credential sets on the resource if databases consist of different users. For example, if DBname 1 has credential set A and DBname 2 has credential set B, then create separate credentials sets on the resource.
  • If you have multiple database names with the same port, use the following syntax: `DBname1, DBname2,..` (Comma-separated).

Assign template from device management policies

Device management policies help manage resources. You can assign monitoring templates, knowledge base articles, and custom attributes using device management policies. The device management policy can be applied to one or a set of resources. For more information, see Create Policies.

View resource metrics

The gateway monitors the application using the assigned templates and displays the results in graphical format. To view resource metrics, click the desired database resource name > resource Details > Metrics.



Verify the following if the graphs are not plotted correctly:

  • The resource is accessible and Telnet is established for the IP address and port.
  • Valid credentials are used for the resource.

If you experience MySQL monitoring issues, follow these troubleshooting steps:

  1. Verify server and gateway connectivity using Ping.
ping <IP Address>


  1. Verify Telnet-to-server listening port connectivity.
telnet <IP Address> <Port>


telnet 1433
  1. Execute the following commands from GCLI to verify the database connectivity:
db <Database Type> <IP Address> <User Name> <Password> <Port> <Database Name> <Connect Timeout> <ReadTimeout> <Secure Flag> <Query>


db mysql mysql Pass@123 5432 root 15000 10000 insecure "show global status like 'innodb_row_lock_waits" 

From gateway version 5.3.0, use the following format to execute the command along with the result-set:

db <Database Type> <IP Address> <User Name> <Password> <Port> <Database Name> <Connect Timeout> <Read Timeout> <Secure Flag> <ResultSet?: Yes/No> <Query>


db mssql mysqlPass@123 5432 root 15000 10000 insecure Yes "show global status like 'innodb_row_lock_waits”
