Azure Load Balancers Monitoring

Host Template: Cloud - Azure - Load Balancers

This host template is one of 31 developed by Opsview to provide the most comprehensive Azure monitoring in the industry.

Azure Load Balancers allow you to scale applications, providing your services with high availability. They support TCP and UDP applications for both inbound and outbound scenarios with high throughput/low latency. Load Balancers contain frontend and backend pools which balance traffic according to health probes and Load Balancer Rules which you can define. Public Load Balancers can also allow your Virtual Machines to possess outbound connections by translating private IP addresses to public IP addresses.

This Host Template allows you to monitor all the metrics you need to efficiently run Load Balancers on Microsoft Azure. After installation, you'll be able to check your endpoint availability, as well as monitor packet and bytes transmission accurately.

This Host Template includes the following Service Checks:

Service Check Name	Description	Default Thresholds (Warning, Critical)	UOM
Azure - LB - Endpoint Availability	Availability of VIP (Virtual IP) and DIP (Dynamic IP) endpoints, based on probe results [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	N/A
Azure - LB - Packets Transmitted	Total number of Packets/SYN Packets transmitted within time period [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	N/A
Azure - LB - Bytes Count	Total number of Bytes transmitted within time period [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	B

NOTE: The "Default Timespan" given for these Service Checks refers to the time period we use when retrieving metrics from Azure.

NOTE: See details about Nagios thresholds here.

Usage Instructions

To use this Host Template you will need to provide access to the subscription you wish to monitor

Navigate to the Subscriptions section and select your Subscription.

In the Subscription to be monitored, click Access Control (IAM).

Then click the Add button, select the required role and select the application, once for each of the following roles: * Reader

Repeat these steps for each subscription you wish to monitor.

Step 1: Add this Host Template

Add the Cloud - Azure - Load Balancers Host Template to your Opsview Monitor host. If the resource you're monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.

For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.

Step 2: Add and configure variables required for this Host Template

The Service Checks in this Host Template use the following variables, and they will be added to your Opsview Monitor instance when you import the Opspack:

AZURE_CREDENTIALS

The Value is not used and therefore can be set to anything. Override the arguments with your Azure Credentials.

Parameter	Position in Variable	Name	Description
--subscription-id	Arg1	Subscription ID	The Subscription ID of your Azure Subscription
--client-id	Arg2	Client ID	The Client ID of your Azure Subscription
--secret-key	Arg3	Secret Key	The Secret Key of your Azure Subscription
--tenant-id	Arg4	Tenant ID	The Tenant ID of your Azure Subscription

AZURE_RESOURCE_DETAILS

The Value is not used and therefore can be set to anything. Override the arguments with your Azure Resource Details.

Parameter	Position in Variable	Name	Description
--resource-group	Arg1	Resource Group	Name of the Azure resource group to be monitored
--resource-name	Arg2	Resource Name	Name of the Azure resource to be monitored

For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.

For mode-specific help, run the plugin with the -h -m <mode> flags. This will list the required and optional Variable Arguments for that mode. The appropriate mode for each Service Check is listed here:

Service Check Name	Mode
Azure - LB - Endpoint Availability	`Az.Net.LB.Availability`
Azure - LB - Packets Transmitted	`Az.Net.LB.Packets`
Azure - LB - Bytes Count	`Az.Net.LB.Bytes.Count`
