Can't send about fluent-plugin-slack

[sonots]

It is wierd. out_slack.rb does require slack_client.rb and, it does require net/http at

fluent-plugin-slack/lib/fluent/plugin/slack_client.rb

Line 2 in 34ba9b2

require 'net/http'

. So, Net::OpenTimeout must be defined.

In my environment, irb tells like follows:

irb> Net::OpenTimeout
NameError: uninitialized constant Net
irb> require 'net/http'
irb> Net::OpenTimeout
Net::OpenTimeout

The ruby version was 2.1.2.

Could you tell me your td-agent version and its ruby version?

[airtoxin]

I use system ruby 2.1.2 and td-agent 2.1.0(fluentd 0.10.53)
But fluentd use ruby 1.9.1.
fluentd's irb says

irb(main):001:0> Net::OpenTimeout
NameError: uninitialized constant Net
    from (irb):1
    from /usr/lib64/fluent/ruby/bin/irb:12:in `<main>'
irb(main):002:0> require 'net/http'
=> true
irb(main):003:0> Net::OpenTimeout
NameError: uninitialized constant Net::OpenTimeout
    from (irb):3
    from /usr/lib64/fluent/ruby/bin/irb:12:in `<main>'

And another try, I insert some debug logs in slack_client.rb

      def post(endpoint, params)
log.info "@endpoint: ", endpoint
        http = proxy_class.new(endpoint.host, endpoint.port)
        http.use_ssl = (endpoint.scheme == 'https')
        http.verify_mode = OpenSSL::SSL::VERIFY_NONE
        http.set_debug_output(debug_dev) if debug_dev
log.info "@http: ", http

        req = Net::HTTP::Post.new(endpoint)
log.info "@req: ", req
        req['Host'] = endpoint.host
        req['Accept'] = 'application/json; charset=utf-8'
        req['User-Agent'] = 'fluent-plugin-slack'
        req.body = encode_body(params)

        res = http.request(req)
        response_check(res, params)
      end

and got a new log

no req output so Net::HTTP::Post.new(endpoint) failed.

@airtoxin I fixed fluent-plugin-slack to work with ruby 1.9.3. Could you try the latest version? It could work with 1.9.1 possibly although I won't support ruby 1.9.1 officially. 1.9.1, even 1.9.3 are end of life already.

[airtoxin]

@sonots It works!
And I try to update td-agent newer one. Very thank you!
