Filebeat
Listens to the “beat” of logs.
Sysbeat
Listens to the internal “beat” of systems via APIs.

Filebeat: Capture Log Messages
• A “Beat” based on the Logstash-Forwarder source code
• Do one thing well: • Send log files to Logstash & Elasticsearch
• Light on consumed resources • Easy to deploy on multiple platforms
www.elastic.co5
Filebeat JSON output
The log message
The timestamp
The log level
www.elastic.co6
Features
• Handles Log Rotation • Send at least ones • Last Reading State • Filtering
www.elastic.co7
Upcoming Features
• Multi Line Support • Windows Event Log • Filtering
www.elastic.co8
Packetbeat: Capture network packets
• Visibility into the infrastructure
• Passively listening to network packets
• It doesn’t add latency • It cannot break your
application

Packetbeat Idea
look at the communication between services
www.elastic.co10
Packet capturing
1. Using port mirroring 2. As an “agent”
www.elastic.co11
Matching requests and responses
• Pipelining complicates matching the requests with the responses.
www.elastic.co12
Create a JSON object for each request-response pair
HTTP transaction
GET method
Response code
Response time

Topbeat
• Like the Unix top command but sending the data periodically to Elasticsearch
• Works also on Windows
www.elastic.co14
Topbeat system wide and per process stats
CPU “steal” time
Total / used / freememory
CPU statsPer process stats
CPU time consumed
Process pid, name,parent pid, etc.
Memory used

Topbeat output objects
File system stats
Mount point
Device name
Total, used, freedisk space

Libbeat
• Go library • Foundation of
all beats
www.elastic.co17
Libbeat Basics
• Provides common things for all Beats • Configuration • ES & Logstash Connectivity • Logging • Configuration file handling • CLI flags, service handling
Dev guide for creating a new Beat: https://www.elastic.co/guide/en/beats/libbeat/current/index.html
www.elastic.co18
Setup & Run
• Download Binary • Run ./filebeat -c filebeat.yml • Supported Platforms • Platforms supported by Golang (1.5.1)
• Build your own binary • git clone https://github.com/elastic/filebeat • cd filebeat • make
www.elastic.co19
Beats Deployment: directly to ES
• Option 1: Insert directly into Elasticsearch via the bulk API
• Security can be provided via Shield and HTTPs
www.elastic.co20
Beats Deployment: Send to Logstash
• Option 2: Insert via Logstash
• Uses the Lumberjack protocol which offers security
• Gives the opportunity of enriching or modifying the data
www.elastic.co21
Community Beats - Create your own beat
• Dockerbeat: Docker container statistics • Nginxbeat: Status from Nginx • Pingbeat: ICMP Ping round trip time • Uwsgibeat: Stats from uWSGI • More to come
