+## Break down data to see what's contributing to your ingest [#facet-data-ingest]
+
+<Callout variant="important">
+This feature is currently in limited availability. If you're interested in getting access, speak to your New Relic account representative. 
+  </Callout>
+
+You can inspect your data ingest to gain more information about your ingest health. This way, you'll know your baselines, and can more easily spot an anomaly like an ingest spike, as well as its source. 
+
+To break down your ingested data, start from the chart on the **Data ingestion** page. Think of the data source bands as the Y axis, and the dates as the X axis. Click on the band you want to inspect at the spot in the X axis that corresponds with the date you want to investigate.

+
+A modal opens with the account, data source, and facet selected. You can do a handful of things on this page:
+
+* Change the account, data source, or facet to drill down into.
+* Change the date and time to investigate. 
+* Review the results of the query in chart form. The chart displays the top 15 results for the facet query. 
+* Open the NRQL query in the **Query builder** where you'll find additional facets that you can use.  
+
+Learn more about [NRQL queries here](/docs/query-your-data/nrql-new-relic-query-language/get-started/introduction-nrql-new-relics-query-language/).

+### How we break your ingest data down
+
+ Some of the content in the UI is variable, depending on your account. This information is intended to help you understand how we're working with your ingest data.
+
+* The chart on the **Data ingestion** page shows data usage for a little longer time frame than that covered by your retention settings for each data ingest source. If you choose a date outside of your designated retention period for an ingest source, you'll get the message that there's no chart data available. Select a more recent date to fix this problem.
+*  If you inspect a data source for an account that has less than a terrabyte of data, we compute the ingest volume over a 24 hour period; otherwise, we compute it for a 1 hour period.
+* The ingest value provided on the main **Data ingestion** chart will be slightly different from that reflected during inspection. This is because our facet computation is an estimate.

 ## Set alerts for data use [#set-alerts]
 
 [Query and alert on usage data](/docs/accounts/accounts-billing/new-relic-one-pricing-users/usage-queries-alerts) describes how to set alerts to get notified if you're nearing data ingest limits you don't want to cross. For example, you might set an alert on logs, which can stack up quickly in an active system.
