Unable to launch logstash and ingest data - Got response code '401' contacting Elasticsearch at URL 'http://localhost:9200/_xpack'

(soumya ranjan sahoo) #1

Hi team,

Let me provide a short background to this - I was able to successfully ingest data to the engine using logstash. It is only after installing x-pack that I run into the following error stack upon passing the following command for ingesting data - logstash -f "sys address of the config file".

[2018-06-05T11:00:06,853][WARN ][logstash.licensechecker.licensereader] Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"http://logstash:xxxxxx@localhost:9200/", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :error=>"Got response code '401' contacting Elasticsearch at URL 'http://localhost:9200/'"}

Further, I assume it is some kind of connection/auth issues.

Request you to help me identify the fix.

Thanks in advance.

Can we have your elasticsearch and logstash yml settings?

I haven't changed any of the elasticsearch.yml settings. It is unedited.

Just added the following to logstash.yml -

xpack.monitoring.elasticsearch.username: "logstash"
xpack.monitoring.elasticsearch.password: "6PkpVXNoAFD0EyD6cHT0"
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.url: "http://localhost:9200"
xpack.management.elasticsearch.url: "http://localhost:9200"

And the following to kibana.yml. (I am successfully able to launch kibana post xpack installation) -

elasticsearch.url: "http://localhost:9200"
elasticsearch.username: "kibana"
elasticsearch.password: "RWRRVobuxYGYBZgISypa"

Kindly help me fix this. Let me know in case you need further info from my end.

Thanks in advance.

I think its authentication issue. Could you try comment out or remove this line in logstash.yml

xpack.monitoring.elasticsearch.username: "logstash"
xpack.monitoring.elasticsearch.password: "6PkpVXNoAFD0EyD6cHT0"

I did commented out the 2 lines in my logstash.yml. Didn't work for me. Kindly request your attention on this.

Thanks in advance.
