# Events ingestion monitoring

This page shows you how to start using the events ingestion monitoring API.

When we collect activities, we track the number of events that go through each step of the mediarithmics data pipeline.

This API is a mediarithmics [Data cube](https://developer.mediarithmics.io/resources/data-cubes) and works similarly to [Activities analytics queries API](https://developer.mediarithmics.io/querying-your-data/activities-analytics-queries).

| metrics<mark style="color:red;">\*</mark>    | array      | Array of [Metric](https://developer.mediarithmics.io/resources/data-cubes/reference#metric) to retrieve.                                                                                |
| dimension\_filter\_clauses                   | object     | Filters to apply on dimensions before calculating the metric. For more information, see [FilterClause](https://developer.mediarithmics.io/resources/data-cubes/reference#filterclause). |
| dimensions<mark style="color:red;">\*</mark> | Dimensions | [Dimensions](https://developer.mediarithmics.io/resources/data-cubes/reference#dimension) to group metrics by.                                                                          |
| date\_ranges                                 | array      | Periods to analyze. Each date range is an object with a `start_date` and an `end_date`. See [DateRange](https://developer.mediarithmics.io/resources/data-cubes/reference#daterange).   |

Here is a sample [report request](https://developer.mediarithmics.io/resources/data-cubes/creating-a-report#report-request) body payload with all the important properties:

<pre class="language-json"><code class="lang-json"><strong>{
</strong>    // Retrieve the data in the specified date range
    // Mandatory

            "start_date": "2021-10-10T00:00:00",

## Available pipeline steps

We monitor the number of events that reach the given ingestion steps:&#x20;

<table><thead><tr><th>Step</th><th>Description</th></tr></thead><tbody><tr><td><pre><code>JS_TAG
</code></pre></td><td>Measure the number of events sent by the mediarithmics Javascript TAG </td></tr><tr><td><pre><code><strong>API

## Retention

These aggregated stats are kept for 3 months.
