Redis

Ship Redis Application logs to Logstash

Step 1 - Install Filebeat

deb (Debian/Ubuntu/Mint)

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

rpm (CentOS/RHEL/Fedora)

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

macOS

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

Windows

Download the Windows zip file from the official downloads page.
Extract the contents of the zip file into C:\Program Files.
Rename the -<version>-windows directory to ``.
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 as a Windows service:

cd 'C:\Program Files\'
.\install-service-.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-.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 file

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

Step 3 - Enable the Redis Module

There are several built in filebeat modules you can use. You will need to enable the redis module.

deb/rpm

sudo filebeat modules list
sudo filebeat modules enable redis

macOS

cd <EXTRACTED_ARCHIVE>
./filebeat modules list
./filebeat modules enable redis

Windows

cd <EXTRACTED_ARCHIVE>
.\filebeat.exe modules list
.\filebeat.exe modules enable redis

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

deb/rpm /etc/filebeat/modules.d/
mac/win <EXTRACTED_ARCHIVE>/modules.d/

- module: redis
# Main logs
log:
  enabled: true

  # Set custom paths for the log files. If left empty,
  # Filebeat will choose the paths depending on your OS.
  #var.paths: ["/var/log/redis/redis-server.log*"]

# Slow logs, retrieved via the Redis API (SLOWLOG)
slowlog:
  enabled: true

  # The Redis hosts to connect to.
  #var.hosts: ["localhost:6379"]

  # Optional, the password to use when connecting to Redis.
  #var.password:

Step 4 - Configure output

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"]

No input available! Your stack is missing the required input for this data source Talk to support to add the input

Step 5 - Validate configuration

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

Step 6 - Start Filebeat

Ok, time to start ingesting data!

deb/rpm

sudo systemctl enable filebeat
sudo systemctl start filebeat

macOS

./filebeat

Windows

PS C:\Program Files\Filebeat> Start-Service filebeat
