Instead, configure your synthetic monitors directly on the Kibana instance where you want to view and manage them. You may, however, use Dashboards and the Discover feature with CCS to view `synthetics-*` indices. The Synthetics UI does *not* work with CCS/CCR because it would limit the rich user experience that the Synthetics UI provides. Unlike the majority of Kibana apps, the Synthetics UI relies heavily on state stored in Kibana shared objects in order to provide a rich user experience. Because Kibana saved objects cannot be shared via CCS/CCR, the Synthetics UI will not show any user data even if CCS/CCR is configured. ## Synthetics UI does not support autodiscovery for infrastructure or Kubernetes monitoring The Synthetics app is designed for active synthetic checks against user-defined URLs and user journeys. It is not intended for infrastructure or Kubernetes pod monitoring through autodiscovery. The Synthetics UI only shows monitors that are explicitly created and managed through the [Synthetics UI](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/6446/solutions/observability/synthetics/create-monitors-ui) or a [Synthetics project](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/6446/solutions/observability/synthetics/create-monitors-with-projects). It has no mechanism for dynamic autodiscovery of infrastructure targets, and it is not designed to ingest or display the high volume of short-lived monitor results that infrastructure monitoring typically produces. For infrastructure or Kubernetes uptime monitoring, use one of the following approaches instead: - **[Heartbeat](https://docs-v3-preview.elastic.dev/elastic/beats/tree/main/reference/heartbeat) with autodiscovery**: Run Heartbeat on your infrastructure and use [autodiscovery](https://docs-v3-preview.elastic.dev/elastic/beats/tree/main/reference/heartbeat/configuration-autodiscover) to dynamically monitor hosts and pods. Results appear in the [Uptime app](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/6446/solutions/observability/uptime). - **Elastic Agent with the Uptime Monitors integration**: Deploy a standalone Elastic Agent and configure the Uptime Monitors (Heartbeat) integration to collect availability data from your infrastructure. The Uptime app is deprecated as of 8.15 and is not available in Serverless. ## Manage large numbers of Synthetic monitors with tags When managing larger numbers of synthetic monitors, use tags to keep them organized. Many of the views in the Synthetics UI are tag-aware and can group data by tag. ## Create custom dashboards If we don't provide a UI for your exact needs, you can use [dashboards](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/6446/explore-analyze/dashboards) to build custom visualizations. For a complete accounting of fields used by the Synthetics UI, refer to [Heartbeat's exported fields](https://docs-v3-preview.elastic.dev/elastic/beats/tree/main/reference/heartbeat/exported-fields).
