SCG: Jak shromažďovat stav SCG z rozhraní API

To bylo testováno v bráně Secure Connect Gateway verze 5.10.00.10.

Níže jsou uvedeny kroky potřebné k provedení dotazu rozhraní API do SCG za účelem shromáždění všech informací o stavu:
 

1. Povolte rozhraní REST API v bráně bezpečného připojení.
   Chcete-li umožnit integraci s nástroji a aplikacemi datového centra, musíte v bráně SCG povolit rozhraní REST API.
   Chcete-li povolit rozhraní API, otevřete panel SCG ve webovém prohlížeči (https://<IP_SCG>:5700), přejděte na Nastavení > nastavení API nastavení, zaškrtněte políčko Povolit rozhraní API pro tuto bránu a klikněte na Použít:
2. Otevřete relaci SSH na bránu SCG pomocí uživatele root a proveďte následující příkazy:
   Vygenerování ověřovacího tokenu pomocí brány SCG – před získáním autorizačního tokenu je nutné provést všechny dotazy rozhraní API na bránu SCG. V tomto případě získáme autorizační token a uložíme ho do systémové proměnné, abychom usnadnili další dotazy API:

   AUTH_TOKEN=`curl -k -s -L -i -X --header "Content-Type: application/json" --request POST --data '{"username":"admin","password":"admin_password"}' 'https://10.108.0.40:5700/SupportAssist/api/v2/auth/token?accessToken' | grep "accessToken" | awk -F ":" {'print $2'} | sed 's/,$//' | sed 's/^..//' | sed 's/.$//'`

   Kde:
   • admin = administrátor SCG
   • admin_password = heslo správce SCG
   • 10.108.0.40 = IP adresa SCG
   Příklad:

   scg:~ # AUTH_TOKEN=`curl -k -s -L -i -X --header "Content-Type: application/json" --request POST --data '{"username":"admin","password":"admin_password"}' 'https://10.108.0.40:5700/SupportAssist/api/v2/auth/token?accessToken' | grep "accessToken" | awk -F ":" {'print $2'} | sed 's/,$//' | sed 's/^..//' | sed 's/.$//'`
   
   scg:~ # echo $AUTH_TOKEN

3. Spuštění dotazu rozhraní API pro získání stavu SCG:
   Pomocí tohoto API dotazu je možné zobrazit mnoho informací o SCG:
   - Stav připojení
   - Stav keepalive
   - Stav každé služby SCG (esrshttpd, esrshttpdR, esrsconnectemc, networkConnectivity a další)
   - Stav monitorovaných zařízení
   
   Níže je uveden dotaz rozhraní API pro shromáždění stavu informací:

Uložení sestavy do souboru:

curl -k -X GET --header "Accept: application/json" -o report_scg.txt --header "Authorization: Bearer $AUTH_TOKEN" https://10.108.0.40:5700/SupportAssist/api/v2/service/healthstatus?

Kde:
-o report_scg.txt = Tato volba se používá k uložení výstupu do "report_scg.txt" soubor.

Důležité – mechanismy ověřování:
Proces ověřování začne, když klient požádá o token ze serveru zadáním svých přihlašovacích údajů. Brána bezpečného připojení jako odpověď vrátí přístupový token a obnovovací token. Obnovovací token je platný po dobu 24 hodin, zatímco přístupový token je platný po dobu 30 minut. Po vypršení platnosti přístupového tokenu můžete pomocí obnovovacího tokenu vygenerovat nový přístupový token.
