是否可以在不使用 Logstash 或 FileBeats 或 Kibana 的情况下将数据索引到 Elastic Search 中？

Question

Elastic Search is new to me. I want to know whether it is possible to index data into Elastic Search with ES framework alone? (without using its stack members like Logstash, FileBeats, Kibana, etc)

Answer 1

You can use curl commands in your terminal. Some famous ones

For delete an index

 curl -X DELETE 'http://localhost:9200/samples'

For listing all indexes

 curl -X GET 'http://localhost:9200/_cat/indices?v'

For adding a document to an index

 curl -XPUT --header 'Content-Type: application/json' http://localhost:9200/samples/_doc/1 -d '{ "school": "Harvard" }'

For bulk load data in JSON format

 export pwd="elastic:" curl --user $pwd -H 'Content-Type: application/x-ndjson' -XPOST 'https://58571402f5464923883e7be42a037917.eu-central-1.aws.cloud.es.io:9243/0/_bulk?pretty' --data-binary @<file>

For showing the cluster health

 curl --user $pwd -H 'Content-Type: application/json' -XGET https://58571402f5464923883e7be42a037917.eu-central-1.aws.cloud.es.io:9243/_cluster/health?pretty

For query and returning some desired fields

 GET filebeat-7.6.2-2020.05.05-000001/_search { "_source": ["suricata.eve.timestamp","source.geo.region_name","event.created"], "query": { "match": { "source.geo.country_iso_code": "GR" } } }

Answer 2

Yes. Big time.

There are a ton of tools you can use and a stack of SDKs, or you roll your own producer to hit the indexing APIs.

Here's a few examples:

• Python Elasticsearch SDK
• Official Elasticsearch Ruby SDK
• Official Elasticsearch Golang SDK
• Fluentd's Elasticsearch output
• Kafka Elasticsearch Connector
• Native Index APIs

Elastic publishes lists ofofficially supported clients and community supported clients , but they're heavy on programming languages and don't include things like the Fluentd output, the Kafka connector, and so on.
