Google Cloud Load Balancing monitoring integration

New Relic Infrastructure's integrations with the Google Cloud Platform (GCP) include an integration to report Google Cloud Load Balancing data to New Relic products. 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:

1. Make sure you have installed the Infrastructure agent before you activate GCP integrations from your Infrastructure account.
2. Follow standard procedures to connect your GCP service to New Relic Infrastructure.

Polling frequency

New Relic Infrastructure 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 infrastructure.newrelic.com > Integrations > Google Cloud Platform > (select an integration).

Metric data

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

GcpHttpLoadBalancerSample

Query GcpHttpLoadBalancerSample events in Insights 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 Insights 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 Insights 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.

Inventory data

To view inventory data for GCP Load Balancing services, go to infrastructure.newrelic.com > Integrations > Inventory and search for or select the following:
