Motivation:
etc/config.py
file is typically installed as something you can't edit. For example, if you're using RPMs, upgrading to next release via RPM will overwrite local changes.By supporting a configuration file (
/etc/tcollector.json
) it's easier to have host-specific customization that isn't destroyed by upgrades.
