通知

管理者は、CloudflareがWARPクライアントとの接続問題やアプリケーションのパフォーマンス低下を検出した際にアラートを受け取ることができます。通知は、メール、Webhook、およびサードパーティサービスを通じて配信されます。

通知の管理

DEX通知はCloudflareダッシュボード ↗で設定されます。詳細については、通知の作成を参照してください。

  • Mode: WARP mode deployed on the device.

Included with

All Cloudflare Zero Trust plans.

What should you do if you receive one?

Review your fleet status to investigate why the spike or drop occurred and which devices are impacted.

DEX test latency

Who is it for?

Zero Trust customers who wish to receive alerts when there is a spike or drop in application latency, as measured by the HTTP test Resource Fetch time or Traceroute test Round trip time. Requires setting up a DEX test.

Other options / filters

• Alert configuration: Choose when to trigger a notification. Available options are Latency spike, Latency drop, and Latency spike or drop.
• Filters:
  • Colo: Cloudflare data center that the device is connected to.
  • Platform: Operating system of the device.
  • Version: WARP client version (for example, 2024.3.409.0).
  • Test name: Choose which DEX test the alert should monitor. You will receive individual notifications for each test.

DEX test low availability

Who is it for?

Zero Trust customers who wish to receive alerts when the percentage of successful HTTP or traceroute requests to an application drops below the selected service-level objective (SLO). Requires setting up a DEX test.

Other options / filters

• Service Level Objective (SLO): Specify the availability threshold that will trigger an alert. Enter a percentage in xx.x format (for example, 98.0).
• Filters:
  • Colo: Cloudflare data center that the device is connected to.
  • Platform: Operating system of the device.
  • Version: WARP client version (for example, 2024.3.409.0).
  • Test name: Choose which DEX test the alert should monitor. You will receive individual notifications for each test.

アラートロジック

Zスコア

Cloudflareは、トラフィックの急増や急減を検出するためにzスコアを使用します。zスコア ↗は、現在の値が平均から何標準偏差離れているかを示します。現在の5分間を過去4時間と比較して、平均と標準偏差を計算します。これは5分ごとに測定されます。

アラートをトリガーするには、zスコアの値が3.5を超えるか、-3.5未満である必要があります。

SLO

サービスレベル目標（SLO）は、(x / y) * 100として定義され、ここでxは良好なイベントの数、yは特定の時間枠内の有効なイベントの数です。DEX通知は、短いウィンドウ（5分）と長いウィンドウ（1時間）の両方を考慮し、いずれかのウィンドウで可用性がSLOの閾値を下回るとアラートをトリガーします。
