+
+## Просмотр статистики
+
+Статистику клиентов WireGuard можно получить используя параметр `show` утилиты `wg`.
+
+Например:
+
+```sh
+wg show all
+```
+
+Команда вернёт следующий результат.
+
+```text
+interface: wg0
+  public key: <public_key>
+  private key: (hidden)
+  listening port: 443
+
+peer: <public_key>
+  preshared key: (hidden)
+  endpoint: <user_ip>:<user_port>
+  allowed ips: 10.253.1.2/32
+  latest handshake: 5 seconds ago
+  transfer: 25.47 MiB received, 282.28 MiB sent
+
+peer: <public_key>
+  preshared key: (hidden)
+  endpoint: <user_ip>:<user_port>
+  allowed ips: 10.253.1.1/32
+  latest handshake: 47 seconds ago
+  transfer: 314.81 MiB received, 776.23 MiB sent
+
+peer: <public_key>
+  preshared key: (hidden)
+  allowed ips: 10.253.1.3/32
+```
+
+Если на машине несколько интерфейсов WireGuard,
+можно вывести статистику по конкретному интерфейсу:
+
+```sh
+wg show wg0
+```
+
+Для наблюдения за статистикой в реальном времени
+можно использовать команду `watch`.
+
+```sh
+watch wg show all
+```
+
+Or:
+
+`wg-json` tool from
+[wireguard-tools](https://git.zx2c4.com/wireguard-tools/tree/contrib/json/wg-json).
+
+## Сбор статистики
+
+Для сбора (дампа) статистики у необходимо добавить аргумент `dump`
+и в терминале отобразится информация в виде таблицы:
+
+```sh
+wg show all dump
+```
+
+```text
+wg0   <private_key>   <public_key>      <listen_port>   <fwmark>
+wg0   <public_key>    <preshared_key>   <endpoint>      <allowed_ips>   <latest_handshake_timestamp>   <transfer_rx>   <transfer_tx>   <persistent-keepalive>
+wg0   <public_key>    <preshared_key>   <endpoint>      <allowed_ips>   <latest_handshake_timestamp>   <transfer_rx>   <transfer_tx>   <persistent-keepalive>
+wg0   <public_key>    <preshared_key>   <endpoint>      <allowed_ips>   <latest_handshake_timestamp>   <transfer_rx>   <transfer_tx>   <persistent-keepalive>
+```
+
+\* [wg.8.en.html#show](https://manpages.debian.org/unstable/wireguard-tools/wg.8.en.html#show)
+on Debian man pages.
+
+## wg-json
+
+В официальный состав инструментов [wireguard-tools](https://git.zx2c4.com/wireguard-tools)
+входит утилита **[wg-json](https://git.zx2c4.com/wireguard-tools/tree/contrib/json/wg-json)**.
+
+[Она](https://git.zx2c4.com/wireguard-tools/tree/contrib/json/wg-json)
+представляет из себя Bash скрипт, который преобразовывает вывод команды
+`wg show all dump` в JSON и возвращает его в терминал.
+
+Утилита не принимает никаких аргументов. Запускать как есть.
