Google Cloud Load Balancing monitoring integration

New Relic's integrations with the Google Cloud Platform (GCP) include an integration to report Google Cloud Load Balancing data to New Relic. This document explains how to activate the GCP Cloud Load Balancing integration and describes the data that can be reported.

Features

Google Cloud Load Balancing is a software-based managed service for distributing traffic in a single or multiple region. It provides seamless, immediate autoscaling and supports the latest application delivery protocols.

Activate integration

To enable the integration follow standard procedures to connect your GCP service to New Relic.

Polling frequency

New Relic integrations query your GCP services according to a polling interval, which varies depending on the integration. The polling frequency for Google Cloud Load Balancer is five minutes. The resolution is 1 data point every minute.

Find and use data

After activating the integration and waiting a few minutes (based on the polling frequency), data will appear in the New Relic UI. To find and use your data, including links to your dashboards and alert settings, go to one.newrelic.com > Infrastructure > GCP > (select an integration).

Metric data

To view metric data for your GCP Load Balancing integration in New Relic, create NRQL queries for GcpHttpLoadBalancerSample, GcpTcpSslProxyLoadBalancerSample, and GcpInternalLoadBalancerSample events and their related attributes.

GcpHttpLoadBalancerSample

Query GcpHttpLoadBalancerSample events in New Relic to view data for the following attributes:

Attribute

Description

https.BackendLatencies

Mean latency (in milliseconds) calculated from when the request was sent by the proxy to the backend until the proxy received from the backend the last byte of response.

https.BackendRequestBytes

The number of bytes sent as requests from HTTP/S load balancer to backends.

https.BackendRequests

The number of requests served by backends of HTTP/S load balancer.

https.BackendResponseBytes

The number of bytes sent as responses from backends (or cache) to HTTP/S load balancer.

https.FrontendTcpRtt

Mean of the Round-Trip Time (RTT) measured for each connection between client and proxy.

https.RequestBytes

The number of bytes sent as requests from clients to HTTP/S load balancer.

https.Requests

The number of requests served by HTTP/S load balancer.

https.ResponseBytes

The number of bytes sent as responses from HTTP/S load balancer to clients.

https.TotalLatencies

Mean of the latency (in milliseconds) calculated from when the request was received by the proxy until the proxy got ACK from client on last response byte.

GcpTcpSslProxyLoadBalancerSample

Query GcpTcpSslProxyLoadBalancerSample events in New Relic to view data for the following attributes:

Attribute

Description

tcpSslProxy.ClosedConnections

Number of connections that were terminated over TCP/SSL proxy.

tcpSslProxy.EgressBytes

Number of bytes sent from VM to client using proxy.

tcpSslProxy.FrontendTcpRtt

Mean of the smoothed RTT (in milliseconds) measured by the proxy's TCP stack, each minute application layer bytes pass from proxy to client.

tcpSslProxy.IngressBytes

Number of bytes sent from client to VM using proxy.

tcpSslProxy.NewConnections

Number of connections that were created over TCP/SSL proxy.

tcpSslProxy.OpenConnections

Current number of outstanding connections through the TCP/SSL proxy.

GcpInternalLoadBalancerSample

Query GcpInternalLoadBalancerSample events in New Relic to view data for the following attributes:

Attribute

Description

l3.internal.EgressBytes

The number of bytes sent from Internal Load Balancing (ILB) backend to client (for TCP flows it only counts bytes on the application stream).

l3.internal.EgressPackets

The number of packets sent from ILB backend to client.

l3.internal.IngressBytes

The number of bytes sent from client to ILB backend (for TCP flows it only counts bytes on the application stream).

l3.internal.IngressPackets

The number of packets sent from client to ILB backend.

l3.internal.RttLatencies

Mean of the RTT (in milliseconds) measured over TCP connections for ILB flows.
