dogapi hungs?

[takus]

I sends some metrics via fluent-plugin-dd, and sometimes its thread hungs. According to stacktrace, It seems that dogapi hungs in connecting https session. Any ideas to fix it?

Hi @takus,

Thanks for reporting this issue.
By default, dogapi-rb has a 5 seconds timeout: beyond, the connection attempt should be dropped. I suspect that the issue could be related with fluent-plugin-dd as it possibly overrides this timeout value.

Would you be able to provide us more information on your dogapi-rb settings through this plugin ?

Thanks

Hi @yannmh,

Thanks for replying. I checked both source code, and default timeout of each lib is nil. I think the setting causes this issue. It seems that Dogapi::APIService has a 5 seconds timeout, but Dogapi::Client. Is that correct?

dogapi-rb/lib/dogapi/facade.rb

Line 14 in a4d3e1c

def initialize(api_key, application_key=nil, host=nil, device=nil, silent=true, timeout=nil)

Thanks

The previous comment is wrong. Dogapi::Client uses Dogapi::v1::xxx in internal. But I noticed that #55 seems to be related to this issue. I'll try to upgrade to the latest version at first.

Great.
Please let me know if upgrading solved your issue.
