# Beats and Elastic Agent capabilities
Elastic provides two main ways to send data to Elasticsearch:
- **Beats** are lightweight data shippers that send operational data to Elasticsearch. Elastic provides separate Beats for different types of data, such as logs, metrics, and uptime. Depending on what data you want to collect, you may need to install multiple shippers on a single host.
- **Elastic Agent** is a single agent for logs, metrics, security data, and threat prevention. The Elastic Agent can be deployed in two different modes:
  - **Managed by Fleet** — The Elastic Agent policies and lifecycle are centrally managed by the Fleet app in Kibana. The Integrations app also lets you centrally add integrations with other popular services and systems. This is the recommended option for most users.
- **Standalone mode** — All policies are applied to the Elastic Agent manually as a YAML file. This is intended for more advanced users. See [Install standalone Elastic Agents](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4780/reference/fleet/install-standalone-elastic-agent) for more information.

The method you use depends on your use case, which features you need, and whether you want to centrally manage your agents.
Beats and Elastic Agent can both send data directly to Elasticsearch or through Logstash, where you can further process and enhance the data, before visualizing it in Kibana.
This article summarizes the features and functionality you need to be aware of before adding new Elastic Agents or replacing your current Beats with Elastic Agents. Starting in version 7.14.0, Elastic Agent is generally available (GA).

## Choosing between Elastic Agent and Beats

Elastic Agent is a single binary designed to provide the same functionality that the various Beats provide today. However, some functionality gaps are being addressed as we strive to reach feature parity.
The following steps will help you determine if Elastic Agent can support your use case:
1. Determine if the integrations you need are supported and Generally Available (GA) on Elastic Agent. To find out if an integration is GA, see the [Integrations quick reference table](https://docs-v3-preview.elastic.dev/elastic/integration-docs/tree/main/reference/all_integrations).
2. If the integration is available, check [Supported outputs](#supported-outputs-beats-and-agent) to see whether the required output is also supported.
3. Review [Capabilities comparison](#additional-capabilities-beats-and-agent) to determine if any features required by your deployment are supported. Elastic Agent should support most of the features available on Beats and is updated for each release.

If you are satisfied with all three steps, then Elastic Agent is suitable for your deployment. However, if any steps fail your assessment, you should continue using Beats, and review future updates or contact us in the [discuss forum](https://discuss.elastic.co/).

## Supported inputs

For Elastic Agents that are centrally managed by Fleet, data collection is further simplified and defined by integrations. In this model, the decision on the inputs is driven by the integration you want to collect data from. The complexity of configuration details of various inputs is driven centrally by Fleet and specifically by the integrations.
To find out if an integration is GA, see the [Integrations quick reference table](https://docs-v3-preview.elastic.dev/elastic/integration-docs/tree/main/reference/all_integrations).

## Supported outputs

The following table shows the outputs supported by the Elastic Agent in 9.0.0-beta1:

  Elastic Defend and APM Server have a different output matrix.

You’d need to install multiple Beats for these use cases.                                                                                                                                                                                                                                                                                                                                                                                                                                                         |

This installs Elasticsearch assets such as index templates and ingest pipelines, and Kibana assets such as dashboards.                                                                                                                                                                                                                                                                                                                      |

Standalone Elastic Agent can use the web UI, API, or YAML. Beats can only be configured through YAML files.                                                                                                                                                                                                                                                                                                                                                                      |

You have to manage Beats configuration yourself or with a third-party solution.                                                                                                                                                                                                                                                                                                                                                                                                                    |

Beats installs hundreds of assets for all modules at once.                                                                                                                                                                                                                                                                                                                                                                                        |

Standalone Elastic Agent and Beats require you to create and manage credentials, and users often share them across hosts.                                                                                                                                                                                                                                                                                                           |

With standalone Elastic Agent and Beats, users often give overly broad permissions because it’s more convenient.                                                                                                                                                                                                                                                                                                                                              |

Users can configure these directly in YAML for standalone Elastic Agent or using the Fleet API for Fleet-managed Elastic Agent. The Integrations app allows users to enter variables, and we are considering a [UI to edit conditions](https://github.com/elastic/kibana/issues/108525). Beats only offers static configuration. |

## Elastic Agent monitoring support

You configure the collection of agent metrics in the agent policy. If metrics collection is selected (the default), all Elastic Agents enrolled in the policy will send metrics data to Elasticsearch (the output is configured globally).
The following image shows the **Agent monitoring** settings for the default agent policy:
![Screen capture of agent monitoring settings in the default agent policy](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4780/reference/fleet/images/agent-monitoring-settings.png)

There are also pre-built dashboards for agent metrics that you can access under **Assets** in the Elastic Agent integration:
![Screen capture of Elastic Agent monitoring assets](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4780/reference/fleet/images/agent-monitoring-assets.png)

The **[Elastic Agent] Agent metrics** dashboard shows an aggregated view of agent metrics:
