Custom Metrics API

The Embrace Custom Metrics API allows you to manage (create, get and delete) the custom metrics of your organization.

Any Custom Metrics you create are available via the Metrics API, which is a separate interface. These metrics can also be forwarded to your organization's observability platform of choice. You can follow this guide to see how to query custom metrics in the Metrics API.

Prerequisites

• Embrace Custom Metrics API Token. This is a different token than the Metrics API token. Contact an Embrace onboarding specialist to get this token for your organization. Once you receive the token, you can proceed independently with creating custom metrics.

API Endpoints

All the endpoints have the same authentication and authorization method, url and parameters. Use the Custom Metrics API token provided by an Embrace onboarding specialist to create custom metrics.

• URL: https://api.embrace.io/custom-metrics

Request

Headers:

• Authorization: we are going to use a Bearer token to authorize and authenticate our requests. i.e.: Authorization: Bearer 7bd49186fed24af699cf93069fc64f03.

URL Params:

• app_id: application id in which we are going to manage the custom metrics. i.e.: appID1
• custom_metric_name: custom metric name that we use to identify it. i.e.: my_custom_metric_name

Body Params:

• name: name you want to provide this new metric i.e.: my_custom_metric_name
• metric: base Embrace metric this new metric will be built from. i.e.: sessions_total.
• group_by: list of group by that we are going to use to group the metric. It can be empty. i.e.: ["os_version", "app_version"].
• filters list of filters that we are going to apply on the metric. It can be empty. i.e.:

{
  "op": "and",
  "children": [{"field_op": "eq", "key": "os_version", "val": "12"}]
}

• time_granularity: list of granularity that we are going to support on this metric. If it is empty, by default hourly is turned on. i.e.: ["five_minute", "hourly", "daily"]
• data_destination: list of data destination to which we are going to send this metric. If it is empty, by default metrics_api is turned on. i.e.: ["metrics_api", "newrelic", "datadog", "grafana_cloud"]

Response

Body Params:

• custom_metric_id: the unique ID for the metric created. i.e.: XZ5BDQk

Status codes:

• 200: request was successful and we return a body with new information.
• 204: request was successful and we don't return a body.
• 400: the url params and body were not correct.
• 403: you don't have access to execute that operation.
• 404: metric that you are trying to consume doesn't exist.
• 409: metric that you are trying to create already exists.
• 500: there was an internal error and you should retry later.

Create custom metric

Request

curl --location 'https://api.embrace.io/custom-metrics/api/v1/app/appID1/custom-metrics' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer 1b6be81cd01c4b08833295efadccafdc' \
--data '{
    "name": "sessions_total_v1",
    "metric": "sessions_total",
    "group_by": ["app_version"],
    "filters": {"op":"and", "children":[{"field_op":"eq","key":"os_version","val":"12"}]},
    "time_granularity": ["five_minute", "hourly"],
    "data_destination": ["metrics_api", "newrelic"]
}'

Filter Parameter Examples

Type	Example
string	{"key": "app_version", "field_op": "eq", "val": "3.2.0"}
int	{"key": "os_major_version", "field_op": "gt", "val": 9}
boolean	{"key": "has_anr", "field_op": "eq", "val": true}
range	{"key": "status_code", "field_op": "eq", "val": {"start": 400", "end": 499}}
property	{"key": "type", "field_op": "eq", "val": {"property_key": "k1", "property_values": ["v1", "v2"]}}

Using duration_bucket filters

For some custom metrics the API allows you to filter data based on the duration_bucket parameter, which categorizes data according to specific duration ranges. Each duration_bucket value corresponds to a specific range of duration values. Here's how it works:

Duration Range	Duration Bucket
0ms to 100ms	0
100ms to 200ms	100
200ms to 300ms	200
300ms to 400ms	300
400ms to 500ms	400
500ms to 600ms	500
600ms to 700ms	600
700ms to 800ms	700
800ms to 900ms	800
900ms to 1000ms	900
1000ms to 2000ms	1000
2000ms to 3000ms	2000
3000ms to 4000ms	3000
4000ms to 5000ms	4000
5000ms to 10000ms	5000
10000ms to 15000ms	10000
Greater than 15000ms	15000

Caution: When filtering with conditions such as duration_bucket < 1100, please be aware that the behavior is based on the order of conditions and the first condition that matches. In this case, if duration_bucket is less than 1100, it will match the condition duration_bucket < 1000, and the duration filter will be < 2000. Ensure that your conditions are structured to achieve your intended filtering accurately.

If you want to filter all durations less or equal than 999 you should create this filter:

{
  "op": "and",
  "children": [{"key": "duration_bucket", "val": 999, "field_op": "lte"}]
}

Request

curl --location 'https://api.embrace.io/custom-metrics/api/v1/app/appID1/custom-metrics/parameters' \
--header 'Authorization: Bearer 1b6be81cd01c4b08833295efadccafdc'
