Connecting VM Agent

​

Prerequisites

• Install VM Agent on your Linux hosts. If VM Agent is not installed yet, start with VM Agent installation.
• Expose Odigos Central externally (for example, via an Ingress, LoadBalancer Service, or another supported exposure method).
• Have a Central endpoint URL that is reachable from your VM hosts.

• odictl
• YAML

Use odictl to connect the VM Agent to Odigos Central.

Open odictl on the host

odictl

2

Go to the Configuration screen

Press c to navigate to the configuration screen.

​

tower.agent_name

Set this to the display name you want to see in Odigos Central.

5

Save the configuration

Press Ctrl+S to save the configuration.

6

Exit odictl

Press Ctrl+C to exit odictl.

7

Restart the odigos-vmagent service

Restart the VM Agent service:

sudo systemctl restart odigos-vmagent.service

Use YAML configuration files to connect VM Agent to Odigos Central.

1

Navigate to the /etc/odigos-vmagent folder

cd /etc/odigos-vmagent

2

Edit the config.yaml file

Edit the config.yaml file using an editor of your choice. The example below uses vi.
