Fields
name

string

Required. Unique name of the resource using the form: projects/{projectId}/locations/global/connectivityTests/{test}
description

string

The user-supplied description of the Connectivity Test. Maximum of 512 characters.
source

object (Endpoint)

Required. Source specification of the Connectivity Test.

You can use a combination of source IP address, virtual machine (VM) instance, or Compute Engine network to uniquely identify the source location.

Examples: If the source IP address is an internal IP address within a Google Cloud Virtual Private Cloud (VPC) network, then you must also specify the VPC network. Otherwise, specify the VM instance, which already contains its internal IP address and VPC network information.

If the source of the test is within an on-premises network, then you must provide the destination VPC network.

If the source endpoint is a Compute Engine VM instance with multiple network interfaces, the instance itself is not sufficient to identify the endpoint. So, you must also specify the source IP address or VPC network.

A reachability analysis proceeds even if the source location is ambiguous. However, the test result may include endpoints that you don't intend to test.
destination

object (Endpoint)

Required. Destination specification of the Connectivity Test.

You can use a combination of destination IP address, Compute Engine VM instance, or VPC network to uniquely identify the destination location.

Even if the destination IP address is not unique, the source IP location is unique. Usually, the analysis can infer the destination endpoint from route information.

If the destination you specify is a VM instance and the instance has multiple network interfaces, then you must also specify either a destination IP address or VPC network to identify the destination interface.

A reachability analysis proceeds even if the destination location is ambiguous. However, the result can include endpoints that you don't intend to test.

}
Fields
ipAddress

string

The IP address of the endpoint, which can be an external or internal IP. An IPv6 address is only allowed when the test's destination is a global load balancer VIP.
port

integer

The IP protocol port of the endpoint. Only applicable when protocol is TCP or UDP.
instance

string

A Compute Engine instance URI.
gkeMasterCluster

string

A cluster URI for Google Kubernetes Engine master.
cloudSqlInstance

string

A Cloud SQL instance URI.
network

string

A Compute Engine network URI.
networkType

enum (NetworkType)

Type of the network where the endpoint is located. Applicable only to source endpoint, as destination network type can be inferred from the source.
projectId

string

Project ID where the endpoint is located. The Project ID can be derived from the URI if you provide a VM instance or network URI. The following are two cases where you must provide the project ID: 1. Only the IP address is specified, and the IP address is within a GCP project. 2. When you are using Shared VPC and the IP address that you provide is from the service project. In this case, the network that the IP address resides in is defined in the host project.

NetworkType

The type definition of an endpoint's network. Use one of the following choices:

Enums
NETWORK_TYPE_UNSPECIFIED Default type if unspecified.
GCP_NETWORK A network hosted within Google Cloud Platform. To receive more detailed output, specify the URI for the source or destination network.
NON_GCP_NETWORK A network hosted outside of Google Cloud Platform. This can be an on-premises network, or a network hosted by another cloud provider.

enum (Result)

The overall result of the test's configuration analysis.
verifyTime

string (Timestamp format)

The time of the configuration analysis.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
error

object (Status)

The details of a failure or a cancellation of reachability analysis.
traces[]

object (Trace)

Result may contain a list of traces if a test has multiple possible paths in the network, such as when destination endpoint is a load balancer with multiple backends.

Result

The overall result of the test's configuration analysis.

Enums
RESULT_UNSPECIFIED No result was specified.
REACHABLE

Possible scenarios are:

  • The configuration analysis determined that a packet originating from the source is expected to reach the destination.
  • The analysis didn't complete because the user lacks permission for some of the resources in the trace. However, at the time the user's permission became insufficient, the trace had been successful so far.
UNREACHABLE A packet originating from the source is expected to be dropped before reaching the destination.
AMBIGUOUS The source and destination endpoints do not uniquely identify the test location in the network, and the reachability result contains multiple traces. For some traces, a packet could be delivered, and for others, it would not be.
UNDETERMINED

The configuration analysis did not complete. Possible reasons are:

  • A permissions error occurred--for example, the user might not have read permission for all of the resources named in the test.
  • An internal error occurred.
  • The analyzer received an invalid or unsupported argument or was unable to identify a known endpoint.

Trace

Trace represents one simulated packet forwarding path.

  • Each trace contains multiple ordered steps.
  • Each step is in a particular state with associated configuration.
  • State is categorized as final or non-final states.
  • Each final state has a reason associated.
  • Each trace must end with a final state (the last step).

steps[]

object (Step)

A trace of a test contains multiple steps from the initial state to the final state (delivered, dropped, forwarded, or aborted).

The steps are ordered by the processing sequence within the simulated network state machine. It is critical to preserve the order of the steps and avoid reordering or sorting them.

FOREIGN_IP_DISALLOWED a Compute Engine instance can only send or receive a packet with a foreign IP address if ip_forward is enabled.
FIREWALL_RULE Dropped due to a firewall rule, unless allowed due to connection tracking.
NO_ROUTE Dropped due to no routes.
ROUTE_BLACKHOLE Dropped due to invalid route. Route's next hop is a blackhole.
ROUTE_WRONG_NETWORK Packet is sent to a wrong (unintended) network. Example: you trace a packet from VM1:Network1 to VM2:Network2, however, the route configured in Network1 sends the packet destined for VM2's IP addresss to Network3.
PRIVATE_TRAFFIC_TO_INTERNET Packet with internal destination address sent to the internet gateway.
PRIVATE_GOOGLE_ACCESS_DISALLOWED Instance with only an internal IP address tries to access Google API and services, but private Google access is not enabled.
NO_EXTERNAL_ADDRESS Instance with only an internal IP address tries to access external hosts, but Cloud NAT is not enabled in the subnet, unless special configurations on a VM allow this connection. For more details, see Special configurations for VM instances.
UNKNOWN_INTERNAL_ADDRESS Destination internal address cannot be resolved to a known target. If this is a shared VPC scenario, verify if the service project ID is provided as test input. Otherwise, verify if the IP address is being used in the project.
FORWARDING_RULE_MISMATCH Forwarding rule's protocol and ports do not match the packet header.
FORWARDING_RULE_NO_INSTANCES Forwarding rule does not have backends configured.
FIREWALL_BLOCKING_LOAD_BALANCER_BACKEND_HEALTH_CHECK Firewalls block the health check probes to the backends and cause the backends to be unavailable for traffic from the load balancer. For more details, see Health check firewall rules.
INSTANCE_NOT_RUNNING Packet is sent from or to a Compute Engine instance that is not in a running state.
TRAFFIC_TYPE_BLOCKED The type of traffic is blocked and the user cannot configure a firewall rule to enable it. See Always blocked traffic for more details.
GKE_MASTER_UNAUTHORIZED_ACCESS Access to Google Kubernetes Engine cluster master's endpoint is not authorized. See Access to the cluster endpoints for more details.
CLOUD_SQL_INSTANCE_UNAUTHORIZED_ACCESS Access to the Cloud SQL instance endpoint is not authorized. See Authorizing with authorized networks for more details.
DROPPED_INSIDE_GKE_SERVICE Packet was dropped inside Google Kubernetes Engine Service.
DROPPED_INSIDE_CLOUD_SQL_SERVICE Packet was dropped inside Cloud SQL Service.
GOOGLE_MANAGED_SERVICE_NO_PEERING Packet was dropped because there is no peering between the originating network and the Google Managed Services Network.
CLOUD_SQL_INSTANCE_NO_IP_ADDRESS Packet was dropped because the Cloud SQL instance has neither a private nor a public IP address.
