Получение данных из Icinga2 с помощью API и powershell

Пример запроса с помощью Curl:

curl -k -s -u 'root:icinga' -H 'X-HTTP-Method-Override: GET' -X POST 'https://192.168.0.209:5665/v1/objects/hosts?filter=match(%22*.mkucou.local%22,host.name)'


curl -k -s -u 'root:icinga' -H 'X-HTTP-Method-Override: GET' -X POST 'https://192.168.0.209:5665/v1/objects/services?service=l016.pshome.local!av-product'

Данные о хостах

Функция выборки данных о хостах с помощью powershell:

```powershell

#Здесь в имени хоста могут быть подстановочные знаки, напрмер "*.mkucou.local"

$result = Get-FromIcinga -hostname "bd2.mkucou.local"

Функия возвращает:

Перебираем массив атрибутов (attrs) и получаем сведения о хостах:

$arr0 = $result.results.attrs

foreach ($arr in $arr0) {
    Write-Host $arr.address
    Write-Host $arr.name
    Write-Host $arr.vars.os
}

Переменные хоста (host.vars):

PS C:\scripts> $arr.vars
