This plugin requires SSL connection, so this bug is practically duplicate of https://perconadev.atlassian.net/browse/PT-191. For now, specify SSL options in the configuration file and pass it with F option of DSN.

Ok, so it'll work, just have to remember to upgrade perl-mysql using experimental packages. Still, at least it is confirmation that you can't use toolkit out-of-box on PS8. I've emailed Marco on this, hoping we can get some priority/focus on it.

Actually, upgrading MySQL did seem to trigger the issue, but then you just need perl-DBD-MySQL from the tools/expermental repo
