Collect and ship Docker container application logs to Logstash and Elasticsearch.
Filebeat is a lightweight shipper that enables you to send your Docker container application logs to your Logit.io Stack. Configure Filebeat using the pre-defined examples below to start sending and analysing your Docker application logs.
Follow this step by step guide to get 'logs' from your system to Logit.io:
Step 3 - Configure Filebeat.yml
The configuration file below is pre-configured to send data to your Logit.io Stack.
Copy the configuration file below and overwrite the contents of the Filebeat configuration file typically located at
# ============================== Filebeat inputs =============================== filebeat.inputs: - type: container enabled: true paths: - '' # ================================== Outputs =================================== output.logstash: hosts: ["your-logstash-host:your-ssl-port"] loadbalance: true ssl.enabled: true
It’s a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com is a great choice.
Step 4 - Validate configuration
If you have issues starting in the next step, you can use these commands below to troubleshoot.
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.
sudo -e -c /etc//.yml
cd <EXTRACTED_ARCHIVE> sudo ./ -e -c .yml
cd <EXTRACTED_ARCHIVE> .\.exe -e -c .yml
Step 5 - Start filebeat
Start or restart to apply the configuration changes.
Step 6 - Launch Logit.io to view your logs
Now you should view your data:
If you don't see logs take a look at How to diagnose no data in Stack below for how to diagnose common issues.
Step 7 - How to diagnose no data in Stack
If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.
Step 10 - Docker Logging Overview
Docker is a platform as a service (PaaS) tool created for building & deploying applications by using containers. Developers use these isolated containers to package an application with all of its required dependencies for streamlined deployment. Docker was first created in 2013 and offers both a free open source solution and paid offering. The platform has been instrumental in the development of cloud-native applications.
Thanks to Docker’s widespread adoption, the trend towards using microservices and containerization has become a must for developers launching applications in the cloud.
Despite this, effective log analysis using Docker’s container logs can easily spiral and run into many complications when trying to keep up with the scaling required for your growing infrastructure. Due to their isolated & distributed nature, centralising Docker log messages is often overly problematic when log data is required for further analysis.
The Logit.io platform provides a single source of truth for container monitoring and log management. We enable your teams to have complete observability across containers, enabling your Developers & IT leaders with the ability to investigate and fix issues faster.
