Mac System Log Files

Ship system log files from macOS to Logstash

Configure Filebeat to ship logs from macOS Systems to Logstash and Elasticsearch.

Step 1 - Install FilebeatCopy

deb (Debian/Ubuntu/Mint)

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-oss-7.8.1-amd64.deb
sudo dpkg -i filebeat-oss-7.8.1-amd64.deb

rpm (CentOS/RHEL/Fedora)

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-oss-7.8.1-x86_64.rpm
sudo rpm -vi filebeat-oss-7.8.1-x86_64.rpm

macOS

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-oss-7.8.1-darwin-x86_64.tar.gz
tar xzvf filebeat-oss-7.8.1-darwin-x86_64.tar.gz

Windows

  • 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:
cd 'C:\Program Files\filebeat'
.\install-service-filebeat.ps1
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 - Enable system moduleCopy

Change into the newly downloaded directory and locate the configuration file:

cd ~/<EXTRACTED_ARCHIVE>/filebeat.yml

There are several built in filebeat modules you can use. To enable the system module run.

./filebeat modules list
./filebeat modules enable system

Additional module configuration can be done using the per module config files located in the modules.d folder, most commonly this would be to read logs from a non-default location

mac <EXTRACTED_ARCHIVE>/modules.d/

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
#output.elasticsearch:
#  hosts: ["localhost:9200"]

Uncomment and change the logstash output to match below.

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

Step 4 - Validate configurationCopy

Let's check the configuration file is syntactically correct by running filebeat directly inside the terminal. If the file is invalid, filebeat will print an error loading config file error message with details on how to correct the problem.

deb/rpm

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

macOS

cd <EXTRACTED_ARCHIVE>
./filebeat -e -c filebeat.yml

Windows

cd <EXTRACTED_ARCHIVE>
.\filebeat.exe -e -c filebeat.yml

Step 5 - (Optional) Update logstash filtersCopy

All Logit stacks come pre-configured with popular Logstash filters. We would recommend that you add macOS 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

  if [fileset][name] == "auth" {
    grok {

      pattern_definitions => {
        "GREEDYMULTILINE"=> "(.|\n)*"
      }
      remove_field => "message"
    }
    date {
      match => [ "[system][auth][timestamp]", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
    }
    geoip {
      source => "[system][auth][ssh][ip]"
      target => "[system][auth][ssh][geoip]"
    }
  }
  else if [fileset][name] == "syslog" {
    grok {
      match => { "message" => ["%{SYSLOGTIMESTAMP:[system][syslog][timestamp]} %{SYSLOGHOST:[system][syslog][hostname]} %{DATA:[system][syslog][program]}(?:\[%{POSINT:[system][syslog][pid]}\])?: %{GREEDYMULTILINE:[system][syslog][message]}"] }
      pattern_definitions => { "GREEDYMULTILINE" => "(.|\n)*" }
      remove_field => "message"
    }
    date {
      match => [ "[system][syslog][timestamp]", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
    }
  }
}
