ECS: ECS SNMP-traps configureren (in het Engels)

1. SNMP instellen om het adres> van de ontvanger in de GUI te <vangen

2. Controleer of de configuratie is ingesteld op het ECS na het toevoegen van een trap-configuratie in de gebruikersinterface.

# sudo /opt/emc/caspian/fabric/cli/bin/fcli-internal lifecycle alert.snmpconfiguration

Node 1:~ # sudo /opt/emc/caspian/fabric/cli/bin/fcli-internal lifecycle alert.snmpconfiguration

  "status": "OK",
  "etag": 73523,
  "snmp_configuration": {

    "snmp_targets": [{

      "privacy_protocol": ""
    }]
  }
}

3. Voer de testwaarschuwingsopdracht uit om een waarschuwing en SNMP-trap te genereren.

4. Voer de volgende opdracht uit om te zien of de trap uit een ander levenscyclusknooppunt in het cluster is gegaan, aangezien de logboekvermelding de meest recente datum heeft. 

# domulti 'grep -i snmp /opt/emc/caspian/fabric/agent/services/fabric/lifecycle/log/lifecycle.log'

5. In een tweede stopverfvenster klikt u op het knooppunt dat in de meest recente logboeken is weergegeven en voert u het volgende uit. 

# tcpdump udp -i any port 162

6. Voer in uw primaire venster de volgende opdracht uit om een testtrap te genereren:

# TOKEN=$(curl -iks https://localhost:4443/login -u '<User:Password>' | grep X-SDS-AUTH-TOKEN);echo $TOKEN;curl -ks -H "$TOKEN" -H "Content-Type: application/json" -d '{"user_str": "ECS Test Alert", "contact": "ecsadmin@company.com"}' https://localhost:4443/vdc/callhome/alert | xmllint --format -;curl -vk -H "$TOKEN" "https://localhost:4443/logout"

7. In het tweede venster zou u het valvuur uit het levenscyclusknooppunt moeten zien. Als de val niet wordt weergegeven, controleer dan opnieuw de logboeken in stap 4, aangezien het zookeeper-knooppunt dat reageert, mogelijk is gewijzigd.
