Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to each host. A single agent makes it easier and faster to deploy monitoring across your infrastructure. The agent’s single, unified policy makes it easier to add integrations for new data sources.
Fleet provides a web-based UI in Kibana to add and manage integrations for popular services and platforms, as well as manage a fleet of Elastic Agents. Our integrations provide an easy way to add new sources of data, plus they ship with out-of-the-box assets like dashboards, visualizations, and pipelines to extract structured fields out of logs. This makes it easier to get insights within seconds.
Integrations in Fleetedit
Fleet provides a web-based UI for configuring integrations with your data sources. This includes popular services and platforms like Nginx or AWS, as well as many generic input types like log files.
The Elastic Agent policy allows you to use any number of integrations for data sources. You can apply the Elastic Agent policy to multiple agents, making it even easier to manage configuration at scale.
When you add an integration, you select the agent policy to use then configure inputs for logs and metrics, such as the path to your Nginx access logs. When you’re done, you save the integration to update the Elastic Agent policy. The next time enrolled agents check in, they receive the update. Having the policies automatically deployed is more convenient than doing it yourself by using SSH, Ansible playbooks, or some other tool.
If you prefer infrastructure as code, you may use YAML files and APIs. Fleet has an API-first design. Anything you can do in the UI, you can also do using the API. This makes it easy to automate and integrate with other systems.
Elastic Agent self-protectionedit
On MacOS and Windows, Elastic Agent can self-protect against malicious users and attackers when the Endpoint Security integration is added to the agent policy. For more information, see Elastic Endpoint self-protection.
Central management in Fleetedit
You can see the state of all your Elastic Agents in Fleet. On the Agents page, you can see which agents are online, which have errors, and the last time they checked in. You can also see the version of the Elastic Agent binary and policy.
Fleet serves as the communication channel back to the Elastic Agents. Agents check in for the latest updates on a regular basis. You can have any number of agents enrolled into each agent policy, which allows you to scale up to thousands of hosts. When you make a change to an agent policy, all the agents receive the update during their next check-in. You no longer have to distribute policy updates yourself.
Data streams make index management easieredit
The data collected by Elastic Agent is stored in indices that are more granular than you’d get by default with the Beats shippers or APM Server. This gives you more visibility into the sources of data volume, and control over lifecycle management policies and index permissions. These indices are called data streams.
