Google Cloud Application Load Balancer Monitoring Integration

Get the best out of your Google Cloud Application Load Balancer service by integrating Site24x7 monitoring. Track forwarding rules, internal metrics, and backend service performance to ensure optimal delivery of your web applications and APIs.

Setup and configuration

Adding Google Cloud Application 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 Application 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 Application 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 Application 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 Application Load Balancer from the Select the Resources for Monitoring list and click Save.
5. After successful configuration, go to Cloud > GCP > Application Load Balancer. Now you can view the discovered Google Cloud Application Load Balancer resources.

Note

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

Polling frequency

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

Supported metrics

The metrics are organized into three categories for better readability: Forwarding Rules, Internal Metrics, and Backend Services.

Forwarding Rules

Metric name	Description	Statistic	Unit
Name	The name of the forwarding rule.	-	-
IP Address	The IP address assigned to the forwarding rule.	-	-
Port range	The range of ports configured for the forwarding rule.	-	-
IP version	The IP version (IPv4 or IPv6) used by the forwarding rule.	-	-
IP protocol	The protocol used by the forwarding rule (e.g., TCP, UDP, ICMP).	-	-
Network tier	The network tier of the forwarding rule (e.g., Premium, Standard).	-	-

Internal Metrics

Metric name	Description	Statistic	Unit
Internal Backend latencies	The latency distribution of requests sent from the load balancer to backends.	Average	Milliseconds
Internal backend request count	The number of requests sent from the load balancer to backends.	Total	Count
Internal Request Bytes	The number of bytes received from clients by the load balancer.	Total	Bytes
Internal Response Bytes	The number of bytes sent to clients by the load balancer.	Total	Bytes
Internal Backend Request Bytes	The number of bytes sent from the load balancer to backends.	Total	Bytes
Internal Backend Response Bytes Count	The number of bytes received by the load balancer from backends.	Total	Bytes
Internal Request Count	The number of requests received by the load balancer from clients.	Total	Count
Internal Total Latencies	The total latency distribution for requests to the load balancer.	Average	Milliseconds

Backend Services

The Backend Services tab displays the following service information:

Information	Description
Service name	The name of the backend service.
Protocol	The protocol used by the backend service (e.g., HTTP, HTTPS, HTTP/2).
Backend groups	The backend groups configured for the service.
Instances	The number of instances in the backend service.
Health check	The health check configured for the backend service.
Healthy hosts	The number of healthy hosts in the backend service.
Unhealthy hosts	The number of unhealthy hosts in the backend service.
Action icon	An icon to set individual thresholds for these metrics.

The Backend Services tab also displays the following metrics:

Metric name	Description	Statistic	Unit
Backend - Healthcheck details	Detailed information about the health check status of the backend.	-	-
Total hosts	The total number of hosts in the backend service.	Count	Count
Healthy hosts	The number of healthy hosts in the backend service.	Count	Count
Unhealthy hosts	The number of unhealthy hosts in the backend service.	Count	Count
Backend HTTP 2XX Error	The number of HTTP 2XX responses from backends that were considered errors.	Count	Count
Backend HTTP 3XX Error	The number of HTTP 3XX responses from backends that were considered errors.	Count	Count
Backend HTTP 4XX Error	The number of HTTP 4XX responses from backends that were considered errors.	Count	Count
Backend HTTP 5XX Error	The number of HTTP 5XX responses from backends that were considered errors.	Count	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 Application 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 > Application 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 Application 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
