--- title: "Resources" canonical: "https://ai-docs.certero.com/space/CXCM/108298896/Resources" format: markdown --- The Resources screen provides detailed reporting and cost exploration. Drill-throughs from resources links on many other screens will load this screen, prefiltered by the context from which you navigated, e.g. filtered by date, service, etc. There is a familiar date range control at the top-right and these tiles at the top show totals for the resources in scope of the screen’s filtering:  The **Possible monthly savings** tile (above) includes a link to the [Optimization Insights](https://certero.atlassian.net/wiki/spaces/CXCM/pages/108299180) screen. A range of dropdowns provide filtering on common categorizations:  The **Breakdown type **control allows you switch the chart and table between three views:  The **OpEx **view displays a bar chart with options for choosing the categorization (color-coding) of the bars of the chart and the time aggregation (for each bar) from daily, weekly or monthly:  Under the chart, the table for this view has ungrouped rows for each resource, but the grouping can be changed:  This view also has an option for exporting the table. The **Resources** view allows you to categorize an area chart AND table by service, region, etc.:  The **Tags** view displays an area chart with a table grouped by resource tag keys. The **Actions **icon for the table rows allow you to filter and un-filter the chart on the tag key for the row:  --- Mousing over a chart datapoint on the **Resources **screen will show a datapoint details tooltip, for example:  --- The **Actions **menu at the top-right allows you to save, manage and recall **Perspectives**. Perspectives are a named combination of filters, breakdown type and categorization that you can save for later use; quickly applying a desired set of report conditions. [Cluster types](https://certero.atlassian.net/wiki/spaces/CXCM/pages/108299476) are explained in another section.  --- In the table for the **OpEx **breakdown type (where each row is a resource) some columns contain navigation links. Clicking on a resource name or OpEx column cost (following image) will take you to the **Resource Details** screen for the single resource.  The R**esource Details** screen has a range of pages:  The **Details **page shows resource details and meta-data. The **Constraints **page allows you to manage resource-level constraints and view constraints violation history. [Constraints](https://certero.atlassian.net/wiki/spaces/CXCM/pages/108299089) are explained in another section. The **OpEx **page displays costs broken down by cost subcategories, giving visibility of the different sources of costs attributed to the resource, for example for compute, licensing or network traffic. The **OpEx** page also reveals granular cost data. The **Optimization Insights** page shows [Optimization Insights](https://certero.atlassian.net/wiki/spaces/CXCM/pages/108299180) recommendations that the resource is currently in scope of, and those from which the resource has been dismissed (excluded). Using the **eye** icons, the resource can be excluded from, or re-included in, the displayed recommendation types. For some resource types (e.g. instances), the **Monitoring **page shows usage metrics charts which are useful for validating usage-related optimisations:
