What is Elastic Agent:

Elastic Agent is a unified tool that simplifies adding monitoring capabilities to your systems. It can collect various data types, including logs, metrics, and even security information, from your hosts. It also offers centralized management on Elastic Cloud, allowing for remote configuration changes.

Elastic Agents are part of the Elastic ecosystem designed to simplify and unify data collection across various sources, facilitating observability, security, and search functionalities. They allow for efficient monitoring of logs, metrics, and other types of data from hosts, thereby enhancing the deployment and management of monitoring infrastructure. Elastic Agents operate under a single, unified approach, aiming to streamline data collection processes, configuration, and scalability across different environments

Elastic Agent Features:

  • Unified Monitoring: Collects logs, metrics, and other data from hosts in a single, streamlined way.
  • Centralized Management: Manage configurations remotely through Elastic Cloud for scalability and ease of use.
  • Security Protection: Offers security features to safeguard your hosts.
  • Data Querying: Enables querying data directly from operating systems for troubleshooting purposes.
  • External Integrations: Connects with external services and systems to provide broader insights.
  • Scalability: Designed for efficient deployment of monitoring across large infrastructures.

How Elastic Agent Works:

  1. Single Agent Installation: You install a single Elastic Agent on each host you want to monitor.
  2. Policy Application: Define policies that specify which data sources (logs, metrics, etc.) to collect and on which hosts. You can apply a policy to multiple agents for consistent configuration at scale.
  3. Data Collection: The agent gathers data based on the applied policy, including logs from specific locations, system metrics, and security information.
  4. Data Forwarding: Collected data is forwarded to the Elastic Stack (Elasticsearch for storage and Kibana for visualization) for analysis and visualization.
  5. Policy Updates: When you update a policy with new integrations or configurations, the enrolled agents automatically receive the changes, simplifying management.

Elastic Agents collect and forward data by being deployed on hosts, where they monitor local conditions and can also gather data from remote services and hardware. This process is facilitated through integrations that connect Elastic to external systems, offering streamlined insights and actions based on the collected data. The agents are managed via policies that specify which integrations to run and on which hosts, allowing for dynamic and scalable configuration management across multiple agents​​.

Elastic’s Fleet component plays a crucial role in managing Elastic Agents by providing a web-based interface for central management. This interface allows users to monitor agent health, manage policies, and roll out updates or changes to multiple agents simultaneously, ensuring efficient and consistent management across the infrastructure​​.

In summary, Elastic Agents and Fleet offer a comprehensive and scalable solution for data collection and management, simplifying the process of deploying monitoring and security measures across a wide array of environments.
