Thanks for your patience.
After analyzing, we found that there was an issue with the mysql_monitoring.py plugin. It used the reserved keyword "version" and assigned the value of MySQL's version.
Since it was a reserved keyword "version", it didn't accept the decimal value and threw an error.
Could you please change the key from "version" to "mysql_version" in the mysql_monitoring.py and perform the re-register option present in the Site24x7 web client.
Navigate to Server > click the respective Server monitor > Plugin Integrations > click "Reregister Plugins
Once done, the mysql_monitoring.py will be added for monitoring.
Apologies for the inconvenience caused.
Hope this works for you. If you need any clarification, please reply to this thread.
