MagicNetworkMonitoringConfig

Source: src/Cloudflare/MagicNetworkMonitoring/Config.ts

The Magic Network Monitoring (MNM) account configuration — the singleton that registers your network’s routers (and optionally WARP devices) as flow-data sources and sets the fallback packet sampling rate.

There is exactly one MNM configuration per Cloudflare account, and MNM rules cannot be created until it exists. Creating a second configuration fails (MnmConfigAlreadyExists), so reconcile tolerates the race by falling through to an update. When the engine has no prior state but a configuration already exists on the account, read reports it as Unowned and takeover is gated behind --adopt.

Creating the configuration

Minimal configuration

const config = yield* Cloudflare.MagicNetworkMonitoringConfig("Mnm", {
  name: "my-network",
  defaultSampling: 1,
});

Configuration with router IPs

const config = yield* Cloudflare.MagicNetworkMonitoringConfig("Mnm", {
  name: "my-network",
  defaultSampling: 100,
  routerIps: ["203.0.113.1/32"],
});

Rules depend on the configuration

const config = yield* Cloudflare.MagicNetworkMonitoringConfig("Mnm", {
  name: "my-network",
  defaultSampling: 1,
});
// Reference an output attribute so the rule deploys after the config.
yield* Cloudflare.MagicNetworkMonitoringRule("VolumetricAlert", {
  accountId: config.accountId,
  type: "threshold",
  prefixes: ["10.0.0.0/24"],
  bandwidthThreshold: 1_000_000,
});
