I have a managed MySQL instance on GCP. Where would I find a query log? Is this something I need to enable first somewhere? I have read their documentation ( https://cloud.google.com/sql/docs/mysql/how-to ) and didn't find it helpful on this topic.
To make your general or slow query logs available, enable the corresponding flag and set the log_output flag to FILE. This makes the log output available using the Logs Viewer in the Google Cloud Platform Console. Note that Stackdriver logging charges apply.
If log_output is set to NONE, you will not be able to access the logs. If you set log_output to TABLE, the log output is placed in a table in your database. If this table becomes large, it can affect instance restart time or cause the instance to lose its SLA coverage; for this reason, the TABLE option is not recommended. If needed, you can truncate your log tables by using the API. For more information, see the instances.truncateLog reference page.
