Describe what happened:
I upgraded from the agent v5 (source install) to v6 (puppy manual compilation), and an import. Nginx and Docker integrations were working fine before the upgrade.

Describe what you expected:
For the Docker and nginx integrations to continue working, but they aren't - "Check docker not found in Catalog"

Steps to reproduce the issue:
Install v5, then v6 (both from source, on ARM), and import the conf in the v6.

Additional environment details (Operating System, Cloud provider, etc):
Scaleway, Ubuntu 16.04, armv7l arch.

Hi @sofixa,

the puppy Agent has a smaller set of features compared to the regular Agent build, specifically it doesn't include any Docker support so not being able to load the docker check is expected. Since you're building from sources, you can try customising the build and add Docker support to the puppy Agent but this is not supported so you'll be on your own.

@masci and is there some sort of doc on the features of the puppy agent?
