Monitors / Ping

Ping

ICMP echo. If the network blocks ping, the probe tries TCP 443 then 80.

How it works

The worker sends one ICMP echo. Inside Docker that needs cap_add: [NET_RAW] on the worker. If ICMP fails, the same check falls back to opening TCP 443, then 80. A successful TCP fallback still counts as connected.

There is no HTTP status or certificate. Conditions are about reachability, latency, and the resolved IP.

Target

Hostname or IP. No scheme or port.

example.com

Placeholders

Available on this type. See conditions for operators and pat() / has() / len() / any().

[CONNECTED] [RESPONSE_TIME] [IP] [DOMAIN_EXPIRATION]

Defaults

New monitors of this type start with:

[CONNECTED] == true[RESPONSE_TIME] < 50

Example conditions

[CONNECTED] == true[RESPONSE_TIME] < 50

GraphQL

type is Ping. Same fields as the admin, camelCase in the input (intervalSeconds, requestBody, probeIds).

mutation {
  createMonitor(input: {
    name: "Edge"
    type: Ping
    target: "example.com"
    conditions: ["[CONNECTED] == true"]
  }) { id }
}

Terraform

Resource is nominal_monitor from returnearly/nominal. type is Ping. Shared arguments match the shared fields in snake_case (name, target, interval_seconds, probe_ids, channel_ids). Omitted conditions use the type defaults.

resource "nominal_monitor" "edge" {
  name       = "Edge"
  type       = "Ping"
  target     = "example.com"
  conditions = ["[CONNECTED] == true"]
}
