Getting Started with HashiCorp Nomad - Monitoring Application Logs

The video tutorial explains how to monitor applications running in a Nomad environment. It covers three main methods: using allocation logs, the Nomad CLI, and streaming logs via the API. Each method is detailed with steps on how to access and configure logs, including setting file retention and size limits. The tutorial also provides examples using a Tetris job running in a Docker container, demonstrating how to view logs for troubleshooting and performance monitoring.

Why is it important to monitor application logs in a Nomad environment?

• To reduce the size of the application

• For security, performance, and troubleshooting purposes

• To enhance the visual appearance of the application

• To increase the speed of the application

Where do tasks running on Nomad log their output by default?

• To an external logging service

• To the Nomad client under the ALOC logs directory

• To the user's local machine

• To the Nomad server

What is one thing you cannot change about logging in Nomad?

• The number of log files retained

• The ability to disable logging for tasks

What is required to view logs using the Nomad CLI?

• A special hardware device

• A specific browser extension

• An internet connection

• A valid ACL token

Which allocation ID is used when streaming logs using the API?

• The short allocation ID

• The long allocation ID

• Any random ID

• The server ID

What is a benefit of streaming logs using the API?

• It increases the speed of the application

• It reduces the size of log files

• It allows for real-time monitoring of logs

• It automatically fixes errors in the logs

What can be done with logs obtained via the API?

• They can be deleted automatically

• They can be uploaded to an upstream server

• They can be converted into a video

• They can be encrypted for security
