Fetcher to send API data to Logz.io

The API Fetcher offers way to configure fetching data from APIs every defined scrape interval.

Setup

Pull Docker Image

Download the logzio-api-fetcher image:

docker pull logzio/logzio-api-fetcher

Configuration

Create a local config file config.yaml.
Configure your API inputs under apis. For every API, mention the input type under type field:

General API

For structuring custom API calls use type general API with the parameters below.

Configuration Options

Parameter Name	Description	Required/Optional	Default
name	Name of the API (custom name)	Optional	the defined url
url	The request URL	Required	-
headers	The request Headers	Optional	{}
body	The request body	Optional	-
method	The request method (GET or POST)	Optional	GET
pagination	Pagination settings if needed (see options below)	Optional	-
next_url	If needed to update the URL in next requests based on the last response. Supports using variables (see below)	Optional	-
response_data_path	The path to the data inside the response	Optional	response root
additional_fields	Additional custom fields to add to the logs before sending to logzio	Optional	Add type as api-fetcher
scrape_interval	Time interval to wait between runs (unit: minutes)	Optional	1 (minute)

Pagination Configuration Options

If needed, you can configure pagination.

Parameter Name	Description	Required/Optional	Default
type	The pagination type (url, body or headers)	Required	-
url_format	If pagination type is url, configure the URL format used for the pagination. Supports using variables (see below).	Required if pagination type is url	-
update_first_url	True or False; If pagination type is url, and it's required to append new params to the first request URL and not reset it completely.	Optional if pagination type is url	False
headers_format	If pagination type is headers, configure the headers format used for the pagination. Supports using variables (see below).	Required if pagination type is headers	-
body_format	If pagination type is body, configure the body format used for the pagination. Supports using variables (see below).	Required if pagination type is body	-
stop_indication	When should the pagination end based on the response. (see options below).	Optional (if not defined will stop on max_calls)	-
max_calls	Max calls that the pagination can make. (Supports up to 1000)	Optional	1000

Pagination Stop Indication Configuration

Parameter Name	Description	Required/Optional	Default
field	The name of the field in the response body, to search the stop indication at	Required	-
condition	The stop condition (empty, equals or contains)	Required	-
value	If condition is equals or contains, the value of the field that we should stop at	Required if condition is equals or contains	-

Using Variables

Using variables allows taking values from the response of the first request, to structure the request after it.
Mathematical operations + and - are supported, in order to add or reduce a number from the variable value.

Use case examples for variable usage:

1. Update a date filter at every call
2. Update a page number in pagination

To use variables:

• Wrap the variable name in curly brackets
• Provide the full path to that variable in the response
• Add res. prefix to the path.

Example: Say this is my response:

{
  "field": "value",
  "another_field": {
    "nested": 123
  },
  "num_arr": [1, 2, 3],
  "obj_arr": [
    {
      "field2": 345
    },
    {
      "field2": 567
    }
  ]
}

Paths to fields values are structured like so:

• {res.field} = "value"
• {res.another_field.nested} = 123
• {res.num_arr.[2]} = 3
• {res.obj_arr.[0].field2} = 345

Using the fields values in the next_url for example like so:

next_url: https://logz.io/{res.field}/{res.obj_arr[0].field2}

Would update the URL at every call to have the value of the given fields from the response, in our example the url for the next call would be:

https://logz.io/value/345

And in the call after it, it would update again according to the response and the next_url structure, and so on.
