@dcoleman17 might be related to your bucketing work

[dcoleman17]

Looks like it is the bucketing changes. I think that self.current_mbc should be initialized to {} instead of None at https://github.com/DataDog/dd-agent/blob/master/aggregator.py#L471 and https://github.com/DataDog/dd-agent/blob/master/aggregator.py#L580
I'll look a bit more.

@dcoleman17 this issue has started to pop up in the field (https://datadog.desk.com/agent/case/9575). Can you make sure it gets fixed and release soon?

Fixed a while back.

I am still getting this:

mysql
-----
  - instance #0 [ERROR]: TypeError("argument of type 'NoneType' is not iterable",)
  - Collected 28 metrics & 0 events
  - Dependencies:
      - MySQLdb: 1.2.3

Collector 4.2.1 just installed... :(

I'm getting this also, version 4.3.0

[clofresh]

Do you have an options value in your mysql.yaml but don't specify anything for it? Is it fixed when you remove the options value altogether?

[rawkode]

Removing the empty options array worked a treat.

Thanks, @clofresh.

[sirshurf]

Same here... removed empty options...
