Mac System Log Files

deb (Debian/Ubuntu/Mint)

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.15.1-amd64.deb
sudo dpkg -i -oss-7.15.1-amd64.deb

rpm (CentOS/RHEL/Fedora)

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.15.1-x86_64.rpm
sudo rpm -vi -oss-7.15.1-x86_64.rpm

macOS

curl -L -O https://artifacts.elastic.co/downloads/beats//-oss-7.15.1-darwin-x86_64.tar.gz
tar xzvf -oss-7.15.1-darwin-x86_64.tar.gz

Windows

• Download and extract the Windows zip file.
• Rename the -<version>-windows directory to ``.
• Open a PowerShell prompt as an Administrator.
• Run the following to install as a Windows service:

.\install-service-.ps1

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/

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"]

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

deb/rpm

sudo  -e -c /etc//.yml

macOS

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

Windows

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

All Logit.io 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
