HTTP json metricset

This is the json metricset of the HTTP module.

Features and Configuration

The JSON structure returned by the HTTP endpoint will be added to the provided namespace field as shown in the following example:

{
  "@timestamp": "2017-05-01T13:00:24.745Z",
  "beat": {
    "hostname": "mbp",
    "name": "mbp",
    "version": "6.0.0-alpha1"
  },
  "http": {
    "http_json_namespace": {
      "date": "05-01-2017",
      "milliseconds_since_epoch": 1493643625474.000000,
      "time": "01:00:25 PM"
    }
  },
  "metricset": {
    "host": "date.jsontest.com",
    "module": "http",
    "name": "json",
    "namespace": "http_json_namespace",
    "rtt": 238397
  },
  "type": "metricsets"
}

Here the response from date.jsontest.com is returned in the configured http_json_namespace namespace:

{
      "date": "05-01-2017",
      "milliseconds_since_epoch": 1493643625474.000000,
      "time": "01:00:25 PM"
}

It is required to set a namespace in the general module config section.

request.enabled

With this configuration enabled additional information about the request are included. This includes the following information:

  • HTTP Header
  • HTTP Method

Exposed fields, Dashboards, Indexes, etc.

Since this is a general purpose module that can be tailored for any application that exposes a JSON structure, it comes with no exposed fields description, dashboards or index patterns.

Fields

For a description of each field in the metricset, see the exported fields section.

Here is an example document generated by this metricset:

{
    "@timestamp": "2017-10-12T08:05:34.853Z",
    "beat": {
        "hostname": "host.example.com",
        "name": "host.example.com"
    },
    "http": {
        "json": {
            "hello": "world"
        }
    },
    "metricset": {
