Azure Load Balancer Monitoring Integration

Azure Load Balancer scales your applications and offers high-availability, low-latency, high-throughput services. You can scale up to millions of flows for all TCP and UDP applications using Azure Load Balancer.

You can now monitor your load balancer, get precise analytics, set thresholds, automate operations, and stay on top of outages with Site24x7's integration.

Setup and configuration

You can add Azure Load Balancer while adding a new monitor or you can add it to an existing Azure monitor. Follow these steps to add the service.

Supported metrics

Metric name	Description	Statistic	Unit
Allocated SNAT Ports	Total number of Source Network Address Translation (SNAT) ports allocated within the time period	Average	Count
Byte Count	Total number of bytes transmitted within the time period	Average	Count
Health Probe Status	Average load balancer health probe status per time duration	Average	Count
Packet Count	Total number of packets transmitted within the time period	Average	Count
SYN Count	Total number of synchronize (SYN) packets transmitted within the time period	Average	Count
SNAT Connection Count	Total number of new SNAT connections created within the time period	Average	Count
Used SNAT Ports	Total number of SNAT ports used within the time period	Average	Count
Data Path Availability	Average load balancer data path availability per time duration	Average	Count

Threshold configuration

Global configuration

Go to the Admin section on the left navigation pane.
Select Configuration Profiles from the left pane and choose Threshold and Availability (+) from the drop-down menu. Click Add Threshold Profile from the top right corner.
Choose Azure Disk as the monitor type.

You can also set the threshold values for all the metrics mentioned above.

Monitor-level configuration

Go to Cloud > Azure and select Azure Disk from the drop-down menu.
Choose a resource for which you would like to set a threshold and then click the hamburger icon on the top. Choose the Edit option, which will direct you to the Edit Azure Load Balancer Monitor page.

You can set the threshold values for the metrics by selecting the Threshold and Availability option. You can also configure IT automation at the attribute level.

Default threshold for disk optimization

Site24x7 alerts you based on a set of default thresholds. These default thresholds ensure that your load balancer is not overutilized, thus maintaining optimal storage and performance. This also helps in reducing costs by getting alerts for unusual changes. The default thresholds are as follows:

Metrics threshold:

Allocated SNAT Ports
Used SNAT Ports
Byte Count
Packet Count
SYN Count
SNAT Connection Count
Data Path Availability
Health Probe Status

Additional attributes threshold

Alert if a resource in the Backend Pool goes down
Alert if an instance in the Load Balancing Rule fails
Unhealthy Hosts
Healthy Hosts
Total Hosts
Healthy Host Percentage

IT Automation

You can configure Site24x7's IT Automation to auto-resolve performance degradation issues.

Summary:

The Summary tab will help you view the Byte Count, Packet Count, Allowed SNAT Ports, and SYN Count-related information. With this information, you can monitor traffic patterns and identify bottlenecks.

Backend Address Pools:

This tab has the list of the backend pools along with the statuses of the resources, Network Interfaces, and Virtual Networks, which are all mapped to their respective monitor views, IP addresses, and rules-related details. With this information, you can verify the backend connectivity and troubleshoot resource mapping issues.

Load Balancing Rules:

This tab provides the list of load balancing rules and their instances, along with their statuses (healthy/unhealthy). You can also view the reason for the instance failure and related details to take corrective actions such as redistributing traffic or scaling resources.

Load Balancing Rules

Frontend IP Configurations:

This tab contains the list of IP configurations and their IP addresses, which are mapped for monitoring.

Frontend IP Configuration

Inbound NAT Rules:

You can view the details of the IP configuration and the Target details of the rule and ensure that inbound traffic rules are configured correctly for Target resources.

Inbound NAT Rules

Outbound Rules:

This tab provides the configuration details with which you can review outbound rules to optimize traffic flow.

Outbound Rules

Configuration details:

This tab provides the configuration details of your Azure Load Balancer. Details on the Compute Size, Pricing Tier, and many more are included in this section.

Zia Forecast

By leveraging the AI-driven Zia framework, you can examine resource consumption measurements through the forecast chart located in the Zia Forecast tab. This chart predicts upcoming performance metrics based on a seven-day historical data analysis, providing insights into the expected metric usage for the next seven days.

Outages

The Outages tab provides the history of Azure AI Search statuses, including Down, Trouble, and Critical.

Inventory

The Inventory tab provides details on licensing, threshold and availability profiles, the set notification profiles, the set user alert group, and the monitor's created time and modified time.

Log Report

The Log Report tab lists all the logs collected during every data collection along with their statuses.
