Did some digging into telegrafs from llama-charmers and telegraf-charmers, and it looks like this telegraf 34 revision belongs to the unsupported telegraf-charmers version. I'd recommend switching to the latest version of the charm in the llama-charmers directory.

However, looking into the new, supported versions of the telegraf charm, the ntpmon layer has since changed and no longer setups up the ntpmon service (thus no ntpmon telegraf coverage) without the ntpmon options install-dir and service-name configured in the Telegraf layer.yaml file. I will create a bug for that issue and comment it here.
