I'm getting the below error when trying to enable nginx module on filebeat.

elastic@ip-172-31-13-13:~/filebeat-7.8.0-darwin-x86\_64$ ./filebeat modules enable nginx  
-bash: ./filebeat: cannot execute binary file: Exec format error

Can someone please help with this.

Hi @Nhavene

It looks like you are on a Linux instance & trying to run a downloaded MacOS executable, can you check in the lab instructions to make sure you are using the path where you use a Filebeat installed on the local Linux instance

Hi @Nhavene

In general we'd recommend to use the version aligned with the course. If you wish to download a different version to experiment, you should make sure to use the appropriate architecture, so for example, _darwin_ won't work on a Linux Server or VM as this is built for MacOS
