System info

Expected behavior

I expect the datadog service check metric will be parsed without a problem while having the config datadog_extensions = true.

Actual behavior

Additional info

It’s also weird that there’s jmxfetch-config and then jmxfetchconfig (without hyphen) , but the latter one may be some our internal thing.
