# Infrastructure History - Overview

**No Infrastructure Left Behind!** The Infrastructure History page acts as a diving off point to see EC2s, Lambda Functions, RDS, Fargate, and other individual resources.

Here you can see Resource Details such as Operating Service and other details provided by the Cloud Provider specifically for this service. You can also see Tags as well as a larger chart to view uptime.

Primarily the Infrastructure History page uses your selected Segment as the initial filter. Additional search options such as Untagged Resources are available to help further refine the search.

## Infrastructure List and Details

Here you can see:

* Usage metrics
* Cost
* Savings
* How Commitments are being applied to the infrastructure

If you have created a segment, it's also a quick way to verify the infrastructure is mapped properly — all the relevant information (accountId, tags, etc.) used in segment creation is available here.

If you have just launched some new Infrastructure, we recommend checking it out in the Infrastructure History page for coverage a few days after launch, as it takes some time for coverage to be applied. AWS and other Cloud Providers will randomly assign commitment coverage to assets.

**Hovering over coverage icons provides more information about:**

* Coverage
* Uptime
* Utilization (if available)

## Search on Multiple Fields

You can search on a number of fields such as:

* Region
* Name
* Operating system

## Searching and Filters

To get more granular you can select core Filters such as:

* Resource Type
* Region
* Service

to drill down on specifically. The mode option of AND/OR either combines the Filters in an AND operator or allows you to search for alternatives with an OR.

Remember this page is initially filtered by Segment at the top — the filters are simply to act as a last-mile search.

**Search Untagged** to add the untagged filter.

Available fields will show up as optional filters. They vary between cloud provider, but we provide Region, AccountId, Resource Type, and Service across all.

## Adding a Recommendation

If you want to add a Custom Recommendation, select the Infrastructure that you want and the **Add Recommendation** button will become available at the top.

Clicking Add Recommendation with selected infrastructure resources will automatically link the infrastructure. The selected resource is referenced under the Infrastructure section in Custom Recommendation, and the related Segment is already pre-selected so the recommendation will go to the relative team.

We recommend making recommendations on a team's Primary Segment as that is used in reporting for Groups.
