Registry Expiry Date — Мониторинг оплаты домена

Print Friendly, PDF & Email

Задача:

В системе Zabbix, настроить мониторинг Registry Expiry Date (Срок действия или регистрации домена). Иначе говоря, настроить отслеживание времени регистрации домена.

---------------------------------------------------------------

Мониторить будем с самого сервера zabbix, поэтому проверяем наличие необходимых утилиты на сервере и при отсутствии устанавливаем.

[root@s18393 ~]# whois yandex.ru

[root@s18393 ~]#

Для мониторинга оплаты домена важна строка «Registry Expiry Date«, её и будем выделять из всего текста.

[root@s18393 ~]# whois yandex.com | grep 'Registry Expiry Date'
   Registry Expiry Date: 2021-09-23T04:00:00Z
[root@s18393 ~]#

Чтобы вывести только дату и время, можно использовать awk. Выведем начиная с четвертого элемента строки.

[root@s18393 ~]# whois yandex.com | grep 'Registry Expiry Date'| awk '{print $4}'
2021-09-23T04:00:00Z
[root@s18393 ~]#

Для удобства вычисления переведём время Unix формат. Это формат определяет количество секунд, прошедших по UTC с полуночи 00:00:00 1 января 1970 года. Этот момент называют «эпохой Unix» (англ. Unix Epoch).

[root@s18393 scripts]# date --date=`whois yandex.com | grep 'Registry Expiry Date'| awk '{print $4}'` +%s
1632369600
[root@s18393 scripts]#

Также нам необходимо знать текущую дату в unix формате

[root@s18393 scripts]# date +%s
1622842391
[root@s18393 scripts]#

Для удобства будем использовать переменные. Затем нам необходимо вычислить разницу между текущей датой и полученным значением и перевести в сутки (Делим на 86400, именно столько секунд в сутках).

d_date=`whois yandex.com | grep 'Registry Expiry Date'| awk '{print $4}'`
d_checkdate=`date --date=$d_date +%s`
d_currentdate=`date +%s `
echo $(( ($d_checkdate-$d_currentdate)/86400 ))

Проверяем работу. Получается, у нас есть ровно сто дней для оплаты домена.

[root@appliance scripts]# d_date=`whois yandex.com | grep 'Registry Expiry Date'| awk '{print $4}'`
[root@appliance scripts]# d_checkdate=`date --date=$d_date +%s`
[root@appliance scripts]# d_currentdate=`date +%s `
[root@appliance scripts]# echo $(( ($d_checkdate-$d_currentdate)/86400 ))
100
[root@appliance scripts]#

Создаём файл для скрипта, и делаем его исполняемым

[root@s18393 ~]# cd /etc/zabbix/scripts/
[root@s18393 scripts]# touch checkdomainexpire.sh
[root@s18393 scripts]# chown zabbix:zabbix checkdomainexpire.sh
[root@s18393 scripts]# chmod +x checkdomainexpire.sh
[root@s18393 scripts]#

содержимое файла checkdomainexpire.sh

d_domain=$1
d_date=`whois $d_domain | grep 'Registry Expiry Date' | awk '{print $4}'`
d_checkdate=`date --date="$d_date" +%s`
d_currentdate=`date +%s`
echo $(( ($d_checkdate-$d_currentdate)/86400 ))

Проверяем работу

[root@appliance scripts]# ./checkdomainexpire.sh yandex.com
100
[root@appliance scripts]#

Переходим к настройке zabbix. Открываем, веб-интерфейс переходим в настройки, выбираем заббикс сервер и добавляем item

Вставляем ключ для проверки и заполняем согласно картинки ниже

system.run[/etc/zabbix/scripts/checkdomainexpire.sh yandex.com]

Интервал проверки (Update interval) устанавливаем один день, этого более чем достаточно.

В завершении необходимо настроит тригер
