const createDashboard = async(name, orgId) => {
    const dbdsAPI = new DashboardsAPI(new InfluxDB({url: __config.influx_url, token: __defaultUser.token, timeout: 20000}));
    await dbdsAPI.postDashboards({body: {name: name, orgID: orgId}}).catch(async error => {
        console.log('--- Error Creating dashboard ---');
        console.error(error);
        throw error;
    });
};

const getDashboards = async(userName) => {

    let user = getUser(userName);

    const dbdsAPI = new DashboardsAPI(new InfluxDB({url: __config.influx_url, token: user.token, timeout: 20000}));

    return await dbdsAPI.getDashboards();
};
