If your MySQL is not getting discovered, you cannot add your MySQL, you are unable to add MySQL server for monitoring, or unable to view your MySQL resources, try discovering your resources by navigating to Server > Server Monitor > Rediscover Applications.
Your MySQL monitor may not be discovered if:
1. You use an older agent version.
Check if the Site24x7 server monitoring agent version is 19.0.0 or above by using the following command:
cat /opt/site24x7/monagent/version.txt
If the agent version is below 19.0.0, please upgrade the agent.
If the agent version is above 19.0.0, check if the Linux agent is promptly running by using the below command:
sudo /opt/site24x7/monagent/bin/monagent status
If the agent is down, start the agent by using the command:
sudo /opt/site24x7/monagent/bin/monagent start
