Sending filebeat data to AWS Elasticsearch service endpoint

Elastic Stack Beats
1

Hi,
I have installed filebeat client on AWS EC2 which is configured to push messages to the AWS Elasticsearch service endpoint. Below is the detail of the filebeat yml file.

## Filebeat ###
filebeat:
  # List of prospectors to fetch data.
  prospectors:
    # Each - is a prospector. Below are the prospector specific configurations
    -
      paths:
        - /var/log/*/*.log
        #- c:\programdata\elasticsearch\logs\*

output:

  ### Elasticsearch as output
  elasticsearch:
    # IPv6 addresses should always be defined as: https://[2001:db8::1]:9200
    hosts: ["search-domain-XXXXXXX-eu-west-1.es.amazonaws.com:80"]
logging:
  # Send all logging output to syslog. On Windows default is false, otherwise
  # default is true.
  to_syslog: true
  # Write all logging output to files. Beats automatically rotate files if rotateeverybytes
  # limit is reached.
  to_files: true
  # To enable logging to files, to_files option has to be set to true
  files:
    # The directory where the log files will written to.
    path: /var/log/mybeat

    # The name of the files where the logs are written to.
    #name: mybeat

    # Configure log file size limit. If limit is reached, log file will be
    # automatically rotated
    rotateeverybytes: 10485760 # = 10MB

    # Number of rotated log files to keep. Oldest files will be deleted first.
    #keepfiles: 7

  # Sets log level. The default log level is error.
  # Available log levels are: critical, error, warning, info, debug
  level: debug
================================================================================

I am unable to perform the bulk upload to the Elasticsearch. Below is the debug logs for the same.

Kindly help me to overcome this issue.

Hello,

What is the reason for sending logs to port 80 and not directly to the elasticsearch/logstash? From what i see in your logs the web server on this aws instance doesn't understand the requests you're sending to it.
You can create firewall rule to allow only your server to access port 9200-9300 for elasticsearch or 5000 for logstash and then you can set the correct port in your filebeat config.

@ngv I am also facing same issue however as per AWS "The service supports HTTP on port 80, but does not support TCP transport."

Does it mean filebeat cannot be used with AWS ElasticSearch service?

HTTP sits on top of TCP. You have to configure port 80 (default TCP port used for HTTP) instead of elasticsearch default port 9200.

5

elasticsearch aws port is 443 use
hosts: ["https://search-domain-XXXXXXX-eu-west-1.es.amazonaws.com:443"]

6

default HTTP port is 80 and default HTTPS port is 443.

I'm also trying to get filebeat to talk to AWS Elasticsearch and running into the same errors. I'm running filebeat 5.0.0 on Ubuntu 14.04 and my config is basically the same as OP's. With additional debugging enabled, I see entries like this:

I've tried about every permutation of host configuration I can think of: "http://search-domain...es.amazonaws.com:80", "search-domain...es.amazonaws.com:80", "https://search-domain...es.amazonaws.com:443", etc.

From the log entries, I can see that it's connecting, getting a successful ping, detecting the version of Elasticsearch, but then something is going wrong and it's generating bad requests.

If I curl http://search-domain...es.amazonaws.com/_template/filebeatI can see that there is a filebeat template there that looks correct.

Has anyone succeeded in getting filebeat to talk to AWS Elasticsearch?

Is there anything else I can try?

No idea about AWS Elasticsearch. Which Elasticsearch version are you using? Can you try a manual bulk index request using curl?

9

I get::

$ curl -XPOST https://search-...amazonaws.com/_bulk --data-binary "@requests"
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"explicit index in bulk is not allowed"}],"type":"illegal_argument_exception","reason":"explicit index in bulk is not allowed"},"status":400}

OK, so I created the cluster with terraform and set "rest.action.multi.allow_explicit_index" = true, which should be right. But now that I dig through the AWS console, it looks like it's set to false. So that's probably the issue.

I've updated it and will try again in a few (AWS ES takes like 20 minutes to process a config change).

Yeah, that was definitely my issue. Thanks for the help.
