}

msrestazure.loginWithServicePrincipalSecret(
  'clientId or appId',

  'AAD domain or tenantId',
  options,
  (err, credentials) => {
    if (err) throw err
    // ..use the client instance to access service resources.
    const client = new LogAnalyticsClient(creds);

    const workspaceId = 'ed6078ff-9048-4dd7-9b21-fc39e3fc7249';
    var body = {
      query: 'Heartbeat | getschema',
      timespan: 'P2D'
    };

    client.query(workspaceId, body).then((result) => {
      console.log('The result is:');
      console.log('Columns:')
      console.table(result.tables[0].columns)
      console.log('Rows:')
      console.table(result.tables[0].rows);
