Cant find interface eth0 for vrrp_instance VI_1

Currently, I am trying to run KEEPALIVED with NGINX on my machine. My use-case includes monitoring the failover behavior for NGINX server because any one instance can go down and I need to have other instance alive to serve the incoming request.

Below is my keepalived.conf file,

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
     track_script {
            chk_http_port
        }
    virtual_ipaddress {
        10.100.160.143
    }
}

vrrp_script chk_http_port {
        script "pidof nginx"
        interval 2

}

below is the error I am getting at location /var/logs/messages

Keepalived_vrrp[33045]: Cant find interface eth0 for vrrp_instance VI_1 !!!

You probably need to check the name of your network interface. Use ifconfig to list all your network interfaces, and look for 'eth0'. If 'eth0' doesn't exist on your machine, then you need to specify the name of an existing interface in your keepalived.conf
