I’m having difficulty configuring the PMM client on a database server. One approach I’ve taken is to uninstall and reinstall the client, however the uninstall script seems to be leaving around configuration which is then picked up during the reinstall. How do I clean out the old configuration before reinstallation?

1.0.3 is old beta version. 1.0.4 was GA. The latest version is 1.0.6. I suggest to install it. To uninstall the old 1.0.3 version: - remove all services from monitoring using pmm-admin - run ./uninstall script - ensure not exporter processes (ps ax|grep pmm) or percona-qan-agent, kill them if any - remove pmm data and server containers
