 When omitting callback parameter (cb), then you can use all function in a promise oriented way. All functions (exept of `version` and `time`) are returning a promis, that you can consume:

+### Async / Await
+
+**Using async / await** (available since node v7.6)
+
+Since node 7.6 you can ylso use the `async` / `await pattern. The example would then loog like this:
+
+```js
+const si = require('systeminformation');
+
+async function network() {
+    try {
+        const data = await si.networkStats('eth1')
+        console.log(`Network Interface Stats (eth1):

+        - RX bytes overall: ${data.rx}
+        - TX bytes overall: ${data.tx}
+        - RX bytes/sec: ${data.rx_sec}
+        - TX bytes/sec: ${data.tx_sec}`)
+    } catch (e) {
