Ask questionsNo metrics gathered, [from Gatherer #1] bad connection
There is a problem when there are no calls to the exporter for a long time, he seems to "fall asleep" and, when asked again, swears like this:
> No metrics gathered, [from Gatherer #1] bad connection
Restarting the exporter solves the problem and it continues to work and returns the metrics normally, as long as requests to it go.

@jesus-velez It's mainly code related, but it's also reflected in the settings. :) It really depends on how a driver interacts with your database instance (and what are the quirks), but you can try an alternative driver
pgx, if you work with Postgres, and/or add
max_connection_lifetime: parameter to
sql_exporter.yml and try it out.
As I said, I had a similar case and was able to find a solution for it. Also, in the fork I currently maintain, the drivers and their dependencies have been updated, it might be the case too.
But yeah, it's a path of trial and errors. I'm happy to support, if you can try things out and provide some intermediate results. :)
