+= Searching and filtering metrics targets
+
+The list of metrics targets can be long. You can filter and search these targets based on various criteria.
+
+In the *Administrator* perspective, the *Metrics Targets* page provides details about targets for default {product-title} and user-defined projects.
+This page lists the following information for each target:
+
+* the service endpoint URL being scraped
+* the ServiceMonitor component being monitored
+* the up or down status of the target
+* the namespace
+* the last scrape time
+* the duration of the last scrape
+
+You can filter the list of targets by status and source. The following filtering options are available:
+
+* *Status* filters:
+** *Up*. The target is currently up and being actively scraped for metrics.
+** *Down*. The target is currently down and not being scraped for metrics.
+
+* *Source* filters:
+** *Platform*. Platform-level targets relate only to default {product-title} projects. These projects provide core {product-title} functionality.
+** *User*. User targets relate to user-defined projects. These projects are user-created and can be customized. 
+
+You can also use the search box to find a target by target name or label.
+Select *Text* or *Label* from the search box menu to limit your search.

+{product-title} Monitoring collects metrics from targeted cluster components by scraping data from exposed service endpoints. 
+
+In the *Administrator* perspective in the {product-title} web console, you can use the *Metrics Targets* page to view, search, and filter the endpoints that are currently targeted for scraping, which helps you to identify and troubleshoot problems. 
+For example, you can view the current status of targeted endpoints to see when {product-title} Monitoring is not able to scrape metrics from a targeted component. 
+
+The *Metrics Targets* page shows targets for default {product-title} projects and for user-defined projects.
