Understanding JavaScript Expressions
Welcome to our tutorial sandbox! This interactive course shows you how to use the different expression types within your Cribl Stream environment. The course should take less than 10 minutes.
This sandbox instance will stay running for 24 hours, after which you can get a new sandbox, but your progress will be lost. To reconnect to the sandbox, just come back to https://sandbox.cribl.io/ and re-enter your email address.
Conventions
In this tutorial, the following formatting indicates (respectively) actions we expect you to take; content you can optionally skip; and commands or content you need to paste into Stream.
Important text shows actions you need to take. For each of these sections, further sections will depend on you having taken these actions in Stream.
Notes contain optional steps. You can skip these without breaking the infrastructure we're building.
Preformatted text contains commands to be
pasted into the terminal, or content
to be pasted into Stream. There is
an easy Copy option available at these
sections' upper-right corner.
Getting Help
If you get stuck during this tutorial feel free to reach out to us on the Cribl Community Slack channel.
Login
Stream should automatically log you in, but if you're idle for too long, or get disconnected, it's possible you'll be prompted for a login. The Username is admin and the Password is cribldemo. You might want to store these to a text file or paper now, just in case.
Terminal
This sandbox includes a terminal console. We'll be working exclusively in the Stream UI, so by default, the terminal is hidden to save screen space. However, you can click the terminal icon to display it.
To hide the terminal again, click the X at its upper right. You can toggle the terminal's display at any time.
