Unlock ELK Beats: Filebeat, Metricbeat, Packetbeat, Winlogbeat & Heartbeat

Beats are lightweight, single‑purpose data shippers in the ELK Stack that forward data to Logstash or Elasticsearch.

Filebeat

Filebeat is a lightweight log collector designed to forward and gather logs from dozens to thousands of servers, containers, or VMs.

Robustness

When Filebeat is interrupted and restarted, it resumes from the last read position using a registry file that records log offsets.

Back‑pressure‑sensitive transmission

Filebeat slows its read‑and‑send rate when Logstash is busy, and speeds up again once Logstash recovers, preventing overload.

Metricbeat

Metricbeat is a lightweight system‑level performance metric collector that gathers CPU, memory, disk, and service metrics such as Redis and Nginx.

Simplified system monitoring

Deploy Metricbeat on Linux, Windows, or macOS to collect statistics on CPU, memory, file systems, disk I/O, and network I/O.

Multi‑module monitoring support

Metricbeat can collect metrics from Apache, NGINX, MongoDB, MySQL, PostgreSQL, Redis, ZooKeeper, and more with zero dependencies—just enable the modules in the configuration.

Container monitoring

When using Docker, a Metricbeat container can read cgroup information directly from the proc filesystem to gather per‑container statistics without needing special Docker API permissions.

Seamless ELK integration

Metricbeat is part of the ELK Stack family and works smoothly with Logstash, Elasticsearch, and Kibana for further processing, analysis, and dashboard creation.

Packetbeat

Packetbeat is a lightweight network packet analyzer that captures and decodes network traffic, similar to Wireshark or Chrome DevTools, and forwards the data to Logstash or Elasticsearch.

Real‑time service and application monitoring

Packetbeat parses protocols such as HTTP in real time, providing insight into how traffic traverses your network without adding latency or requiring code changes.

Support for many application‑layer protocols

Packetbeat includes libraries for a variety of application‑layer protocols.

Searchable and analyzable network traffic

Packetbeat captures, decodes, and enriches network requests and responses, emitting JSON documents that can be indexed in Elasticsearch for search and analysis.

Seamless ELK integration

Packetbeat integrates with the ELK Stack, allowing further processing with Logstash, analysis with Elasticsearch, and visualization with Kibana.

Winlogbeat

Winlogbeat is a lightweight Windows event log shipper that forwards Windows events to Elasticsearch or Logstash.

Read from any Windows event channel

Winlogbeat can be configured to read from any Windows event channel, structuring raw event data for easy filtering and aggregation in Elasticsearch.

Seamless ELK integration

Winlogbeat works with Logstash, Elasticsearch, and Kibana just like the other Beats.

Heartbeat

Heartbeat is a uptime monitoring tool that checks the availability of services by pinging URLs, IPs, or TCP/HTTP endpoints.

Easy to configure

Heartbeat generates uptime and response time data without requiring restarts after configuration changes.

Ping anything you need

Heartbeat supports ICMP, TCP, HTTP, TLS, authentication, and proxies, and can monitor services behind load balancers via simple DNS resolution.

Dynamic target management

Targets can be added or removed automatically by editing a file‑based configuration, which Heartbeat loads on the fly.

Seamless ELK integration

Heartbeat integrates with Logstash, Elasticsearch, and Kibana for further processing and visualization.
