    about • Me, Jun Ohtani / Technical Adovocate ‒ lucene-gosenίϛολʔ

 • Elasticsearch, founded in 2012 ‒ Products: Elasticsearch, Logstash, Kibana, Beats
 Marvel, Shield, Watcher, Graph ‒ Professional services: Support & development subscriptions ‒ Trainings, Consultings 2
  2. 4.

    Lightweight shipper • Small application • Install as agent on

    your servers • Written in Golang • No runtime dependencies • Single purpose 4 https://www.flickr.com/photos/8barbikes/17256970434/
  3. 5.

    Examples of operational data 5 wire data system stats logs

    Packetbeat Topbeat Filebeat Winlogbeat
  4. 7.

    Sniffing the network traffic 7 Client Server sniff sniff •

    Copy traffic at OS or hardware level • Is completely passive • ZERO latency overhead • Not in the request/response path, cannot break your application
  5. 8.

    Sniffing use cases 8 • Security • Intrusion Detection Systems

    • Troubleshooting network issues • Troubleshooting applications • Performance analysis
  6. 10.

    Like the Unix top command but sends the output periodically

    to Elasticsearch. Also works on Windows. 10 Topbeat
  7. 11.

    Topbeat: Exported data 11 • system load • total CPU

    usage • CPU usage per core • Swap, memory usage System wide • state • name • command line • pid • CPU usage • memory usage Per process • available disks • used, free space • mounted points Disk usage
  8. 13.

    Filebeat: Never lose a log line 13 line line line

    line line read pointer Filebeat Logstash Back-pressure sensitive protocol Yo Filebeat, slow it down a bit, pls K buddy line The original log lines act like a queue
  9. 14.

    Filebeat: Parse logs with Logstash 14 • Filebeat sends out

    unparsed log lines • Use filters from Logstash to parse the log lines • Flexible, with conditionals & custom filters • Forward data to other systems using the Logstash output plugins Filebeat Elasticsearch Logstash Other systems
  10. 15.

    Filebeat: Parse logs with Ingest Node 15 • Upcoming in

    5.0 • Filebeat sends out unparsed log lines directly to Elasticsearch • Use Ingest Node processors to parse the log lines • Easier to setup Filebeat Elasticsearch Don’t miss the Ingest Node presentation tomorrow at 2:15 p.m.
  11. 16.

    ‹#› Multiline 16 multiline: # Sticks together all lines #

    that don’t start with a [ pattern: ^\[ negate: true match: after Filebeat extra power • Sticks together related log lines in a single event • For all those long exceptions • Can also be done by Logstash, but it’s sometimes easier to configure the patterns closer to the source
  12. 18.

    Winlogbeat overview 18 • Supports Windows versions starting with XP

    • It remembers how far it read, so it never loses log events • Winlogbeat sends out unparsed Windows event logs • Use Ingest Node or Logstash to parse the Windows event logs

    Logstash • Golang library • Outputs for Elasticsearch and Logstash • At least once guarantees • Encryption & authentication • Common code for configuration files, logging, daemonizing, CLI flags, etc.

    25 • Cross-compiles to all our supported platforms • Produces

    RPMs, DEBs, • Same tools that we use to build the official Elastic Beats • Can be executed from Travis CI Beats Packer

    a new Beat 27 type Beater interface { Config(*Beat) error Setup(*Beat) error Run(*Beat) error Cleanup(*Beat) error Stop() }
