Logstash 7.13 or later no longer ship logs to LogScale up to 1.33.1
Beats log shippers of 7.13 or later no longer ship logs to LogScale

Beats log shippers of 8.0 or later work with a change to the configuration
Beats reports Invalid version from Elasticsearch
Logstash reports Attempted to resurrect connection to dead ES instance, but got an error {:url=>"http://192.168.0.116:9200/", :exception=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :message=>"Elasticsearch Unreachable: [http://192.168.0.116:9200/][Manticore::SocketException] Connection refused"}
Beats reports Failed to connect to backoff(elasticsearch(https://cloud.us.humio.com:443/api/v1/ingest/elastic-bulk)): Connection marked as failed because the onConnect callback failed: Elasticsearch is too old. Please upgrade the instance. If you would like to connect to older instances set output.elasticsearch.allow_older_versions to true.
When using or upgrading to Logstash or Beats log shippers to version 7.13 or later, logs no longer reach LogScale.
Causes
LogScale supports the Elastic Search (ES) API 6.x, Logstash and Beats log shippers of version 7.13 or higher no longer support the ES API 6.2. The result is that Beats and Logstash versions higher than 7.13 are no longer able to communicate with LogScale server. This was corrected in LogScale 1.37.
Beats log shippers v8.0 or later require a small configuration change to retain support.
Solutions
You will need to change the version of Beats or Logstash log shipper to retain compatibility.
The table below summarizes the compatible versions for LogScale and Beats/Logstash.
Beats/Logstash Version LogScale 1.36 and below LogScale 1.37 Logstash 7.16 and up Incompatible Compatible Filebeat 7 and below Compatible Compatible Filebeat 8.0.0 Compatible but requires setup.ilm.enabled: false Compatible but requires setup.ilm.enabled: false Beats 8.0.0 and Later
Beats log shippers 8.0.0 and higher work with a configuration change. To retain compatibility, you need to add the setting
setup.ilm.enabled: false
. For example:yamlfilebeat.inputs: - paths: - /var/log/system.log encoding: utf-8 queue.mem: events: 8000 flush.min_events: 1000 flush.timeout: 1s output: elasticsearch: # Using the standard LogScale API (preferred) hosts: ["192.168.1.117:8080/api/v1/ingest/elastic-bulk"] username: anything password: 50a5c426-7203-4ab3-adcd-2a291be9180a compression_level: 5 bulk_max_size: 200 worker: 5 logging: level: error to_files: true to_syslog: false files: path: ./filebeat-logs/ name: filebeat.log keepfiles: 3 setup.ilm.enabled: false
Beats 8.1.0 and Later
Beats log shippers 8.1.0 and higher work with a configuration change. To retain compatibility, you need to add the setting
output.elasticsearch.allow_older_versions: true
. For example:yamlfilebeat.inputs: - paths: - /var/log/system.log encoding: utf-8 queue.mem: events: 8000 flush.min_events: 1000 flush.timeout: 1s output: elasticsearch: # Using the standard LogScale API (preferred) hosts: ["192.168.1.117:8080/api/v1/ingest/elastic-bulk"] username: anything password: 50a5c426-7203-4ab3-adcd-2a291be9180a compression_level: 5 bulk_max_size: 200 worker: 5 logging: level: error to_files: true to_syslog: false files: path: ./filebeat-logs/ name: filebeat.log keepfiles: 3 setup.ilm.enabled: false output.elasticsearch.allow_older_versions: true
