NoMethodError: undefined method `[]=' for nil:NilClass #4375

Closed ruta-goomba closed 4 years ago

ruta-goomba commented 8 years ago

I'm using logstash-input-cloudwatch plugin and I've got the following config for logstash version 1.5.3:

input { cloudwatch { namespace => "AWS/EC2" metrics => [ "DiskReadOps", "CPUUtilization" ] filters => { "tag:monitored" => "Yes" } region => "eu-west-1" access_keyid => "**" secret_accesskey => "**" } }

output {
stdout { codec => rubydebug }
elasticsearch {
protocol => "http"
host => "127.0.0.1"
}
}

I've tried installing it with elasticsearch version 1.7.4 and 2.1.1, but in both cases logstash does not start and I get the following error in the logstash.err log:

NoMethodError: undefined method `[]=' for nil:NilClass receive at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-1.0.5-java/lib/logstash/outputs/elasticsearch.rb:493 handle at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.3-java/lib/logstash/outputs/base.rb:88 output_func at (eval):27 outputworker at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.3-java/lib/logstash/pipeline.rb:244 start_outputs at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.3-java/lib/logstash/pipeline.rb:166

Thanks for your help.

Have you tried this with the latest version of logstash? Why are you still on 1.5.3?

yes, I've tried the latest version as well. With the latest version I get the following error (with both elasticsearch 2.1.1 and 1.7.4):

NoMethodError: private method `sprintf' called for #Hash:0x49c943c0 event_action_params at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.2.0-java/lib/logstash/outputs/elasticsearch/common.rb:129 event_action_tuple at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.2.0-java/lib/logstash/outputs/elasticsearch/common.rb:33 receive at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.2.0-java/lib/logstash/outputs/elasticsearch/common.rb:23 handle at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.1-java/lib/logstash/outputs/base.rb:81 output_func at (eval):27 outputworker at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.1-java/lib/logstash/pipeline.rb:277 start_outputs at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.1.1-java/lib/logstash/pipeline.rb:194

My output file is different for the latest version, btw. It's:

output { stdout { codec => rubydebug } elasticsearch { hosts => ["localhost:9200"] } }

@ruta-goomba can you paste a sample log line that comes out of logstash-input-cloudwatch?

ruta-goomba commented 8 years ago

As far as I am aware, the plugin does not produce separate logs. The error traces above are from /var/log/logstash/logstash.err

@ruta-goomba

Any further progress or workarounds for this? I'm having the same issue with the logstash-input-cloudwatch plugin. I've tried using with the logstash-output-elasticsearch and logstash-output-amazon_es plugins. Both have errors as above.

ruta-goomba commented 8 years ago

I resolved the issue by rolling back the logstash-input-cloudwatch plugin version to 0.2.2. It works with logstash version 1.5.3 and elasticsearch version 1.7.4.

jrgns commented 8 years ago

@ruta-goomba Can you please try with the latest version of the logstash-input-cloudwatch plugin? 1.1.2 should fix the issues you've mentioned.

jsvd commented 4 years ago

closing this issue as we haven't received further reports of this problem and the ES output has significantly changed since the issue was created
