Hi, I am trying to fetch metrics for ES using "logstash-input-cloudwatch" plugin. As per docs, "filters" configuration is of 'array' type. For fetching ES metrics, I need to pass DomainName and ClientId both, but plugin is throwing an error for datatype. Examples on documentation page shows value as hash rather than array. [https://www.elastic.co/guide/en/logstash/6.6/plugins-inputs-cloudwatch.html#plugins-inputs-cloudwatch-filters](http://plugins-inputs-cloudwatch). I have tried below values for filters, but none worked: `filters => { "DomainName" => "DOMAIN_NAME", "ClientId" => "ACCOUNT_ID" }` `filters => [{ "DomainName" => "DOMAIN_NAME"}, {"ClientId" => "ACCOUNT_ID" }]` Can anybody please suggest on this? Thanks ---

Given the way it is [used](https://github.com/logstash-plugins/logstash-input-cloudwatch/blob/79cf393630cefb69b5d8a89b78b94e41771ad140/lib/logstash/inputs/cloudwatch.rb#L298), the only format that makes sense to me is an array of arrays ``` filters => [[ "DomainName", "DOMAIN_NAME"], ["ClientId", "ACCOUNT_ID"] ] ``` ---

Thanks a lot @Badger. Configuration file is accepted now with multiple filters, but script is failing at next stage with below error: > Error: undefined method `each_pair' for # Did you mean? each_entry Exception: NoMethodError Stack: /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-cloudwatch-2.2.4/lib/logstash/inputs/cloudwatch.rb:179:in `from\_resources' > /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-cloudwatch-2.2.4/lib/logstash/inputs/cloudwatch.rb:163:in `block in run' org/jruby/RubyArray.java:1734:in `each' > /usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-cloudwatch-2.2.4/lib/logstash/inputs/cloudwatch.rb:157:in `run' /usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:426:in `inputworker' > /usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:420:in `block in start\_input' Is it something related to multiple filters? ---

Yeah. The code is inconsistent. It declares filters as an array, and if you want multiple filters [this](https://github.com/logstash-plugins/logstash-input-cloudwatch/blob/79cf393630cefb69b5d8a89b78b94e41771ad140/lib/logstash/inputs/cloudwatch.rb#L298) means it has to be an array. However, all of the documentation shows it as a hash and [this](https://github.com/logstash-plugins/logstash-input-cloudwatch/blob/79cf393630cefb69b5d8a89b78b94e41771ad140/lib/logstash/inputs/cloudwatch.rb#L330) line of code means it has to be a hash. I would say that is a bug and you should mention this on that github issue you replied to a few hours back. ---

Thanks @Badger. I tried debugging the plugin source code but I don't have knowledge about ruby so couldn't find much. Thanks for your pointers. ---
