Google Cloud Network Load Balancer Monitoring Integration

Get the best out of your Google Cloud Network Load Balancer service by integrating Site24x7 monitoring. Know how much traffic your load balancers handle, monitor packet counts, latency metrics, and connection statistics to optimize your cloud infrastructure.

Setup and configuration

Adding Google Cloud Network Load Balancer while configuring a new Google Cloud monitor

If you have not configured a Google Cloud monitor yet, add one by following the steps below:
1. Log in to your Site24x7 account.
2. Go to Cloud > GCP > Add GCP Monitor or Admin > Cloud Monitoring > Google Cloud Platform(GCP).
3. Provide a unique display name for identification purposes.
4. Upload a service account JSON file to authenticate Site24x7 for performing resource discovery.
5. Select Network Load Balancer from the Select the Resources for Monitoring list.
6. Select existing Notification Profiles, User Alerts Groups, Tags, and IT Automation Templates or add new ones. You can also integrate Site24x7's alarms with your preferred third-party service.
7. Click Start GCP Monitoring.
Adding Google Cloud Network Load Balancer to an existing Google Cloud monitor

If you already have a Google Cloud monitor configured for the service account, you can add Google Cloud Network Load Balancer by following the steps below:
1. Log in to your Site24x7 account.
2. Go to Cloud > GCP and select your GCP monitor.
3. Click the hamburger icon next to Service View and select Edit, which brings you to the Edit GCP Monitor page.
4. On the Edit GCP Monitor page, select Network Load Balancer from the Select the Resources for Monitoring list and click Save.
5. After successful configuration, go to Cloud > GCP > Network Load Balancer. Now you can view the discovered Google Cloud Network Load Balancer resources.

Note

It will take approximately five minutes to discover new GCP resources.

Polling frequency

Site24x7's Google Cloud Network Load Balancer monitor collects minute-wise metric data, and the statuses of your Google Cloud Network Load Balancer are reported every five minutes.

Supported metrics

The metrics are organized by load balancer type (L3, L4 proxy, and TCP/SSL proxy) for better readability.

L3 Load Balancer Metrics

Metric name	Description	Statistic	Unit
Egress bytes count	The number of bytes sent from the external network load balancer to the client. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Egress packets count	The number of data packets sent from the external network load balancer to the client.	Average	Count
Ingress bytes count	The number of bytes sent from the client to the external network load balancer. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Ingress packets count	The number of data packets sent from the client to the external network load balancer.	Average	Count
RTT latencies	The average round trip time (RTT) latency measure across TCP connections.	Average	Milliseconds
Egress bytes per internal TCP/UDP load balancer	The number of bytes sent from the internal TCP/UDP load balancer to the client. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Egress packets per internal TCP/UDP load balancer	The number of data packets sent from the internal network load balancer to the client.	Average	Count
Ingress bytes per internal TCP/UDP load balancer	The number of bytes sent from the client to the internal TCP/UDP load balancer. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Ingress packets per internal TCP/UDP load balancer	The number of data packets sent from the client to the internal network load balancer.	Average	Count
RTT latencies per internal TCP/UDP load balancer	The average round trip time (RTT) latency across all TCP connections for internal TCP/UDP load balancer flows.	Average	Milliseconds
Proxy-only addresses	The number of proxy-only addresses segregated by state, active at the time of data collection.	Average	Count

L4 Proxy Load Balancer Metrics

Metric name	Description	Statistic	Unit
Egress bytes count	The number of bytes sent from the external network load balancer to the client. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Ingress bytes count	The number of bytes sent from the client to the external network load balancer. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Closed connections	The total number of connections that were terminated over TCP/SSL proxy load balancer.	Total	Count
New connections	The total number of connections that were created over TCP/SSL proxy load balancer.	Total	Count
Proxy-only addresses	The number of proxy-only addresses segregated by state, active at the time of data collection.	Average	Count

TCP/SSL Proxy Load Balancer Metrics

Metric name	Description	Statistic	Unit
Egress bytes count	The number of bytes sent from the external network load balancer to the client. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Ingress bytes count	The number of bytes sent from the client to the external network load balancer. In case of TCP flow, this metric shows the number of bytes on the application stream.	Average	Count
Closed connections	The total number of connections that were terminated over TCP/SSL proxy load balancer.	Total	Count
New connections	The total number of connections that were created over TCP/SSL proxy load balancer.	Total	Count
Proxy-only addresses	The number of proxy-only addresses segregated by state, active at the time of data collection.	Average	Count
Frontend RTT	The average round trip time (RTT) latency measured by the proxy's TCP stack.	Average	Milliseconds
Open connections	The number of outstanding connections through the TCP/SSL proxy load balancer	Total	Count

Threshold configuration

Global configuration
1. In the Site24x7 web client, go to the Admin section on the left navigation pane.
2. Select Configuration Profiles from the left pane and select Threshold and Availability from the drop-down menu.
3. Click Add Threshold Profile in the top-right corner.
4. For Monitor Type, select Network Load Balancer.
5. Now you can set the threshold values for the metrics listed above.
Monitor-level configuration
1. In the Site24x7 web client, go to Cloud > GCP > Network Load Balancer.
2. Select a resource you would like to set a threshold for, then click the hamburger icon.
3. Select Edit, which directs you to the Edit Network Load Balancer Monitor page.
4. You can set the threshold values for the metrics with the Threshold and Availability option.
5. You can also configure IT Automation at the attribute level.

IT Automation

Site24x7 offers a set of exclusive IT Automation tools that automatically resolve performance degradation issues. These tools react to events proactively rather than waiting for manual intervention. The IT Automation tools automate repetitive tasks and automatically remediate threshold breaches. The alarm engine continually evaluates system events for which thresholds are set and executes the mapped automation when there is a breach.

How to configure IT Automation for a monitor

Configuration Rules

Editing multiple monitors to associate different monitor groups or add a different tag can be a tedious process. With Site24x7's Configuration Rules, you can automate the configuration settings of your monitoring resources. Also, Site24x7 allows you to create custom rules to track configuration changes continuously and achieve the ideal configuration settings.

How to add Configuration Rules
