[google-cloud-sql-discuss] Re: How to get MySQL slow query log in its 'native' format from a Cloud SQL instance?

Hi, 

Not entirely sure how you would use the "gcloud logging read" command for retrieving the requested logs. However, I was able to find out that the flag that you are referring to is included in the Cloud SQL database configuration flag list here. Additionally, you can follow the instructions provided here for the log_output flag. You can either do the following: 

1. log_output : FILE  (this is will make the log output of the slow_query_log available in the Logs viewer section of your Cloud Platform Console.)

2. log_output : TABLE (by setting the output to FILE, the output would be placed in a table inside your database. Note: if the table gets too large, it may cause the instance to lose SLA coverage)

Either way, would you be able to clarify what you mean by "only 'native' MySQL log format"? Our export system of logs currently allows JSON/CSV format at the moment. Would these formats suffice for your use case? 

If the product does not provide the format options you are seeking, you can always feel free to file a Feature Request of the desired export format to the engineering team. Also, if you feel this is a limitation of Cloud SQL, you can always use a Compute Engine instance to run MySQL. This will essentially run the database on a VM instance which in return will allow you more control on the overall configuration of how you want your database to run.   

I hope this helps!

I used to use pt-query-digest and similar utilities for producing reports based on MySQL slow query log.

But AFAIK all these tools know to process only 'native' MySQL log format.

Is there a way to get a log in such format using some "gcloud logging read"  parameters? Or using other methods, besides writing a script by myself?

Thanks,

Vitaly
