Send data via Kafka to your Logstash instance provided by


Collect and ship Kafka application logs to Logstash and Elasticsearch.

Filebeat is a lightweight shipper that enables you to send your Apache Kafka application logs to Logstash and Elasticsearch. Configure Filebeat using the pre-defined examples below to start sending and analysing your Apache Kafka application logs.

Step 1 - Install filebeatCopy

First we need to install filebeat.

deb (Debian/Ubuntu)

sudo apt-get install apt-transport-https
wget -qO - | sudo apt-key add -
echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list

sudo apt-get update && sudo apt-get install filebeat

rpm (Redhat/Centos)

sudo rpm --import
echo "[elastic-6.x]
name=Elastic repository for 6.x packages
type=rpm-md" | sudo tee /etc/yum.repos.d/elastic-beats.repo

sudo yum install filebeat

sudo chkconfig --add filebeat


  • Download the filebeat Windows zip file from the official downloads page.

  • Extract the contents of the zip file into C:\Program Files.

  • Rename the filebeat-<version>-windows directory to filebeat.

  • Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator). If you are running Windows XP, you may need to download and install PowerShell.

  • Run the following commands to install filebeat as a Windows service:

    PS > cd 'C:\Program Files\filebeat'
    PS C:\Program Files\filebeat> .\install-service-filebeat.ps1
    Security warning
    Run only scripts that you trust. While scripts from the internet can be useful,
    this script can potentially harm your computer. If you trust this script, use
    the Unblock-File cmdlet to allow the script to run without this warning message.
    Do you want to run C:\Program Files\Winlogbeat\install-service-filebeat.ps1?
    [D] Do not run  [R] Run once  [S] Suspend  [?] Help (default is "D"): R
    Status   Name               DisplayName
    ------   ----               -----------
    Stopped  filebeat           filebeat
If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example: PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1.
My OS isn't here! Don't see your system? Check out the official downloads page for more options (including 32-bit versions).

Step 2 - Locate configuration fileCopy

deb/rpm /etc/filebeat/filebeat.yml
win <EXTRACTED_ARCHIVE>/filebeat.yml

Step 3 - Configure outputCopy

We'll be shipping to Logstash so that we have the option to run filters before the data is indexed.
Comment out the elasticsearch output block.

## Comment out elasticsearch output
#  hosts: ["localhost:9200"]

Uncomment and change the logstash output to match below.

    hosts: ["your-logstash-host:your-ssl-port"]
    loadbalance: true
    ssl.enabled: true

Step 4 - Enable moduleCopy

There are several built in filebeat modules you can use. To enable the Kafka module, run the following:


filebeat modules list
filebeat modules enable kafka


PS > .\filebeat.exe modules enable kafka

Step 5 - (Optional) Update Logstash FiltersCopy

All Logit stacks come pre-configured with popular Logstash filters. We would recommend that you add Kafka specific filters if you don't already have them, to ensure enhanced dashboards and modules work correctly.

Edit your Logstash filters by choosing Stack > Settings > Logstash Filters

filter {
  if [fileset][module] == "kafka" {
  grok {
     match => { "message" => "(?m)%{TIMESTAMP_ISO8601:[kafka][log][timestamp]}] %{LOGLEVEL:[kafka][log][level]} +%{JAVALOGMESSAGE:[kafka][log][message]} \(%{JAVACLASS:[kafka][log][class]}\)$[ \n]*(?'[kafka][log][trace][full]')" }
  grok {
     match => { "[kafka][log][message]" => "\[%{KAFKA_COMPONENT:[kafka][log][component]}\] +%{JAVALOGMESSAGE:[kafka][log][message]}" }
     pattern_definitions => { "KAFKA_COMPONENT" => "[^\]]*" }
  if "_grokparsefailure" in [tags] {
     mutate { add_field => { "[kafka][log][component]" => "unknown" } }
  grok {
     match => { "[kafka][log][trace][full]" => "%{JAVACLASS:[kafka][log][trace][class]}:\s*%{JAVALOGMESSAGE:[kafka][log][trace][message]}" }
  mutate { rename => { "@timestamp" => "read_timestamp" }
  date { match => [ "[kafka][log][timestamp]", "yyyy-MM-dd HH:mm:ss,SSS" ]
    target => "@timestamp"

Step 6 - Validate configurationCopy

Let's check the configuration file is syntactically correct.


sudo filebeat -e -c /etc/filebeat/filebeat.yml


filebeat.exe -e -c filebeat.yml

Step 7 - Start filebeatCopy

Ok, time to start ingesting data!


sudo systemctl enable filebeat
sudo systemctl start filebeat


Start-Service filebeat
