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

Filebeat JSON output

The log message

The timestamp

The log level

Features

• Handles Log Rotation • Send at least ones • Last Reading State • Filtering

www.elastic.co7

Upcoming Features

• Multi Line Support • Windows Event Log • Filtering

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

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
