NAME

Name of the TCP health check to update.

--check-interval=CHECK_INTERVAL

How often to perform a health check for an instance. For example, specifying 10s will run the check every 10 seconds. See $ gcloud topic datetimes for information on duration formats.

--description=DESCRIPTION

A textual description for the TCP health check. Pass in an empty string to unset.

--healthy-threshold=HEALTHY_THRESHOLD

The number of consecutive successful health checks before an unhealthy instance is marked as healthy.

--proxy-header=PROXY_HEADER

The type of proxy protocol header to be sent to the backend. PROXY_HEADER must be one of:

NONE

No proxy header is added.

PROXY_V1

Adds the header "PROXY UNKNOWN\r\n".

--request=REQUEST

An optional string of up to 1024 characters to send once the health check TCP connection has been established. The health checker then looks for a reply of the string provided in the --response field.

If --response is not configured, the health checker does not wait for a response and regards the probe as successful if the TCP or SSL handshake was successful.

Setting this to an empty string will clear any existing request value.

--response=RESPONSE

An optional string of up to 1024 characters that the health checker expects to receive from the instance. If the response is not received exactly, the health check probe fails. If --response is configured, but not --request, the health checker will wait for a response anyway. Unless your system automatically sends out a message in response to a successful handshake, only configure --response to match an explicit --request. Setting this to an empty string will clear any existing response value.

--timeout=TIMEOUT

If Google Compute Engine doesn't receive a healthy response from the instance by the time specified by the value of this flag, the health check request is considered a failure. For example, specifying 10s will cause the check to wait for 10 seconds before considering the request a failure. See $ gcloud topic datetimes for information on duration formats.

--unhealthy-threshold=UNHEALTHY_THRESHOLD

The number of consecutive health check failures before a healthy instance is marked as unhealthy.

These flags configure the port that the health check monitors. If both --port and --port-name are specified, --port takes precedence.

--port=PORT

The TCP port number that this health check monitors.

--port-name=PORT_NAME

The port name that this health check monitors. By default, this is empty. Setting this to an empty string will clear any existing port-name value.

--use-serving-port

If given, use the "serving port" for health checks:

• When health checking network endpoints in a Network Endpoint Group, use the port specified with each endpoint.
• When health checking other backends, use the port or named port of the backend service.
