Check openstack-nova-list

Overview

Nova is the OpenStack project that provides a way to provision compute instances (aka virtual servers). This monitoring plugin lists all virtual servers and checks their status.

You have to provide a path to an rc file to authenticate. A working rc file might look like this:

export OS_AUTH_URL=https://linuxfabrik.cloud/identity/v3
export OS_IDENTITY_API_VERSION=3
export OS_INTERFACE=public
export OS_PROJECT_DOMAIN_NAME=default
export OS_PROJECT_ID=492a82d9-003a-4f52-8891-406eb19d0573
export OS_PROJECT_NAME=MYPROJECT
export OS_REGION_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_USERNAME=MYUSER
OS_PASSWORD='linuxfabrik'
[ -z "$OS_PASSWORD" ] && read -e -p "Please enter your OpenStack Password for project $OS_PROJECT_NAME as user $OS_USERNAME: " OS_PASSWORD
export OS_PASSWORD
