如何查看NLB監控資訊 - Server Load Balancer

當您遇到網路型負載平衡NLB請求逾時、流量限速等網路連接問題，或者需要瞭解NLB的負載、效能等情況時，您可以利用CloudMonitor功能查看NLB資源的運行狀態和各個指標的使用方式，方便快速定位問題。您可以通過控制台、API、SDK方式來查看NLB的監控資訊。

通過控制台查看監控

登入網路型負載平衡NLB控制台。
在頂部功能表列，選擇NLB執行個體所屬的地區。
在執行個體頁面，您可以選擇以下任意一種方式查看監控。
- 在執行個體列表頁面直接查看
  1. 在執行個體頁面，找到目標執行個體，在監控列單擊。
  2. 在彈出的監控資訊面板，切換執行個體、監聽、VIP（可用性區域）頁簽，查看監控資訊。
- 在執行個體詳情頁面查看
  1. 在執行個體頁面，找到目標執行個體，單擊執行個體ID。
  2. 在執行個體詳情頁簽，單擊監控圖表頁簽。
  3. 在監控圖表頁簽，切換執行個體、監聽、VIP（可用性區域）頁簽，查看監控資訊。
說明
- 關於NLB執行個體監控項詳細說明，請參見NLB監控項說明。
- 系統預設為您展示最近1小時內的監控資料，您可以選擇查看3小時內、6小時內或12小時內的監控資料，還可以選擇自訂，自訂需要設定查看的時間段。
- 開啟自動重新整理後監控圖表每分鐘自動重新整理監控資料。

通過API查看監控

介紹如何通過CloudMonitorAPI查看網路型Server Load Balancer執行個體的監控項和詳細監控資料。

通過API查看監控資料流程，如下圖所示。 monitoring

流程說明如下：

查看資料命名空間Namespace。調用DescribeProjectMeta介面查詢CloudMonitor中NLB的資料命名空間Namespace。
可選：查看已有監控項。調用DescribeMetricMetaList介面查詢CloudMonitor開放的時序類指標監控項描述或直接查看監控項說明，更多資訊，請參見NLB監控項說明。
查看指定監控項的監控資料。
- 調用DescribeMetricLast介面查詢NLB指定監控對象的最新監控資料。
- 調用DescribeMetricList介面查詢NLB指定時間段內監控對象的時序指標監控資料。

DescribeProjectMeta

調用DescribeProjectMeta介面查詢CloudMonitor中NLB的資料命名空間Namespace，詳情請參見DescribeProjectMeta。

登入OpenAPI開發人員門戶。
將請求參數中警示產品標籤過濾Labels的值設定為[{"name":"product","value":"NLB"}]，其他參數保持預設值，然後單擊發起調用。
查看請求樣本
```
http(s)://[Endpoint]/?Action=DescribeProjectMeta
&Labels=[{"name":"product","value":"NLB"}]
&<公用請求參數>
```

根據返回參數，擷取CloudMonitor中NLB資料命名空間Namespace的值為acs_nlb。

DescribeMetricLast

調用DescribeMetricLast介面查詢NLB指定監控對象的最新監控資料。本文以查看執行個體每秒建立串連數InstanceNewConnection的監控資料為例。詳情請參見DescribeMetricLast。

登入OpenAPI開發人員門戶。
在請求參數中，設定查詢InstanceNewConnection的以下請求參數，然後單擊發起調用。
需要配置以下參數，其他參數可保持預設值。
- MetricName：監控項名稱，本文設定為InstanceNewConnection。
- Dimensions：維度map，用於查詢指定資源的監控資料，本文設定為[{"instanceId":"nlb-defs3vztfty3nm****"}]。
- Namespace：產品的資料命名空間，用於區分不同的產品，本文設定為acs_nlb。
