SNMP

Wheel Fudo PAM wspiera funkcję monitorowania stanu systemu z wykorzystaniem protokołu SNMP.


Konfigurowanie SNMP

  1. Wybierz z lewego menu Ustawienia > System.
  2. W sekcji SNMPv3 zaznacz opcję Włączone.
  3. Z listy rozwijalnej Adres IP wybierz adres IP, który będzie używany do komunikacji z innymi systemami poprzez protokół SNMP.
  4. Kliknij Zapisz.
  1. Wybierz z lewego menu Zarządzanie > Użytkownicy.
  2. Kliknij Dodaj.
  1. Z listy rozwijalnej Rola, wybierz service i uzupełnij pozostałe parametry sekcji Ogólne.
  2. W sekcji Uwierzytelnienie, z listy rozwijalnej Typ, wybierz hasło i wprowadź ciąg stanowiący hasło uwierzytelniające użytkownika technicznego.

Informacja

  • Ciąg definiujący hasło musi mieć co najmniej osiem znaków.
  • Konto użytkownika serwisowego uwierzytelniane jest przez usługę SNMP pierwszym skonfigurowanym hasłem statycznym.
  1. W sekcji SNMP, zaznacz opcję Włączone.
  1. Z listy rozwijalnej Metoda uwierzytelnienia, wybierz metodę uwierzytelnienia.
  2. Z listy rozwijalnej Szyfrowanie, wybierz algorytm szyfrujący komunikację SNMP.
  1. Kliknij Zapisz.

SNMP MIBs

MIB wspierane przez Wheel Fudo PAM:

  • MIB-II (RFC 1213)
  • HOST-RESOURCES-MIB (RFC 2790) - częściowe wsparcie
  • UCD-SNMP-MIB

Odczytywanie informacji SNMP poprzez snmpwalk

Informacja

Odczyt danych SNMP wymaga zainstalowania pakietu Net-SNMP 5.7.3.

Pobieranie wszystkich informacji SNMP

snmpwalk -v3 -u "${SNMP_USER}" -a SHA -A "${SNMP_PASSWORD}" -x AES -X "${SNMP_PASSWORD}" -l authPriv "${FUDO_IP}" .1

Pobieranie wybranych informacji SNMP

snmpwalk -v3 -u "${SNMP_USER}" -a SHA -A "${SNMP_PASSWORD}" -x AES -X "${SNMP_PASSWORD}" -l authPriv "${FUDO_IP}" .1.3.6.1.4.1.24410

Dane SNMP Opis
.1.3.6.1.4.1.24410.1.1.1 Status dysków (status ZFS)
.1.3.6.1.4.1.24410.1.1.2

Stan zasilaczy

Informacja

Ta funkcja nie jest wspierana przez wszystkie urządzenia Wheel Fudo PAM. Skontaktuj się z działem wsparcia technicznego Wheel Systems, aby uzyskać więcej informacji.
.1.3.6.1.4.1.24410.1.1.3 Temperatury procesora
.1.3.6.1.4.1.24410.1.1.4 Status S.M.A.R.T

Rozszerzenia SNMP Wheel Fudo PAM

Informacje ogólne

Rozszerzenia SNMP umożliwiają monitorowanie liczby sesji SNMP, status ZFS, status zasilaczy (jeśli jest dostępny), temperaturę rdzeni procesorów, status S.M.A.R.T dysków twardych (temperatura, realokacja sektorów, stan urządzeń).


Specyfikacja pliku MIB rozszerzeń SNMP

Poniższa definicja pliku MIB może zostać wczytana do managera SNMP w celu obsługi rozszerzeń specyficznych dla Wheel Fudo PAM.
