Hi, @sihara !
I think I can working on it this weekend because I'm a little busy this week :-(
Could you give me some informations on your environment? (like collectd config and types.db, ...)

Thank you!

Hi @hoonmin
I'm seeing these too. It would be great if the log would print out the actual value. I will take a look and see if I can figure out what the value actually is.

Looking around, it seems this comes from the json/encoder:

golang/go#3480

It is unable to handle null and so displays this message. At this time there isn't a resolution to this issue.

@yanfali Thank for your time inspect the issue. So we should find some workarounds for this...
