ECS: Como configurar interceptações SNMP do ECS

1. Defina o SNMP para interceptar o <endereço> do destinatário na GUI

2. Confirme se a configuração está definida no ECS depois de adicionar uma configuração de trap na interface do usuário.

# 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": {
    "engine_id": "80001370010A20A9799527B54B",
    "snmp_targets": [{
      "version": "v2",
      "port": 162,
      "hostname": "127.0.0.1",
      "community": "local",
      "username": "",
      "target_id": "816bd926-147e-4309-bf69-492eea94fc7a",
      "authentication_protocol": "",
      "privacy_protocol": ""
    }]
  }
}

3. Execute o comando test alert para gerar um alerta e uma trap SNMP. 

# 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"

4. Execute o seguinte comando para ver se a trap saiu de outro nó do ciclo de vida no cluster, pois a entrada do log terá a data mais recente. 

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

admin@provo:~> domulti 'grep -i snmp /opt/emc/caspian/fabric/agent/services/fabric/lifecycle/log/lifecycle.log | grep 2017-12-11'

5. Em uma segunda janela putty, acesse o ssh no nó que reiniciou os logs mais recentes e execute o seguinte. 

# tcpdump udp -i any port 162

6. Em sua janela primária com execute o seguinte comando para gerar uma trap de teste:

# 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. Na segunda janela, você verá o trap disparar para fora do nó do ciclo de vida. Se a trap não exibir novamente, verifique os logs na etapa 4, pois a resposta do nó do zookeeper pode ter mudado.
