How to send log message from userdata execution to AWS EC2 console for Windows AMI?

Question

I want to send some message logs like Step-1 done , next Step-2 done from the powershell script block to the aws ec2 console screen for windows 2016 instance.

Can any body know how to implement that?

Answer 1

As noted in the AWS documentation, the console for an EC2 instance:

For Windows instances, the instance console output includes the last three system event log errors.

So you can use the PowerShell Write-EventLog scriptlet to write an error event to the System log.

Example:

Write-EventLog -LogName "System" -Source "MyApp" -EntryType Error -Message "Step-1 done"
