Run a script on multiple VMs at once.

[SarthakAgr]

I am working on a project with more than 400 VMs. I am looking for a solution to run a set of  commands or a script on all the VMs at once.

Hello @SarthakAgr ,

You can use OS policy and trigger script for all VMs.

Hi @SarthakAgr , can you elaborate more on your usecase? I would love to know more. 
+ 1 on OS policy usage for now, I am also PM on VM Manager. 
Please feel free to DM me directly if convenient.

Hey @omkarsuram_
Thanks for your reply.
I have a GCP project with more than 400 VMs. I am aiming to monitor the VMs using the 'Wazuh' tool. How it works is, there is a 'wazuh-manager' installed on a server and the on the endpoints, which we want to monitor, 'wazuh-agent' is installed, with communicates with the 'wazuh-manager'. So I am looking for a solution to install 'wazuh-agent' on all the VMs at once, without having to ssh into each VM and running the command individually.
