Using http_poller to search Elasticsearch

Elastic Stack Logstash
1

I want to use http_poller to do the equivalent of this:

curl -XGET 'http://esnode:9200/_all/_search?pretty' -d '{ 
    "query": { 
        "term": {
            "type" : "syslog"
         }
    }
}'

Basically, I want the full power of the Elasticsearch search api.

Using the URI search feature does work. But I think it would be hard to get very complicated in your searches.

Any suggestions? Am I missing something obvious in the docs?

Thanks!

Suggestions for what, exactly?

On how to send the -d part of the curl call via http_poller.

input {

http_poller {
  interval => 30
  urls => {
    test1 => {
      url => "http://esnode:9200/_all/_search?q=type:syslog"
      method => get
    }
  }
  codec => "json"
}

}

output {
stdout { codec => "rubydebug" }
}

Works just fine. But how would I replace the q=type:syslog with what's in the -d '...' part of my example curl call?

I don't want to encode the query in the url. The request body search syntax is a lot easier to understand when you have lots of search parameters.

For example, I'm really not sure how to change this search into something that works in the url.

curl -XGET 'http://node:9200/_all/_search?pretty' -d '{ 
"query":{
  "range":{
    "date":{
      "gt":"now-1m/m"
      },
    "mem.actual_used_p": {
      "gte":0.25
      }
    }
  }
}'
