Azure Virtual Machine Scale Set Monitoring Integration

Azure Virtual Machine Scale Sets help you construct and manage a group of load-balanced VMs. The number of VM instances can be increased or decreased automatically in response to demand or on a predefined schedule. These VM scale sets give your applications high availability while allowing you to manage, configure, and upgrade a large number of VMs from a single location.

You can now monitor your VM scale sets with precise metrics, define thresholds, automate tasks, and stay on top of outages with Site24x7's integration.

Setup and configuration

You can add Azure Virtual Machine Scale Sets while adding a new monitor or you can add it to an existing Azure monitor. Follow these steps to add the service.

Supported metrics

The following metrics are collected:

Metric name	Description	Statistic	Unit
CPU Credits Consumed	The total number of credits consumed by the VM. Only available on B-series burstable VMs	Average	Count
CPU Credits Remaining	The total number of credits available to burst. Only available on B-series burstable VMs	Average	Count
Disk Read Bytes	Bytes read from the disk during the monitoring period	Total	Bytes
Disk Read Operations/Sec	Disk input operations per second (IOPS)	Average	Count per second
Disk Write Bytes	Bytes written to the disk during the monitoring period	Total	Bytes
Disk Write Operations/Sec	The number of disk write IOPS	Average	Count per second
Inbound Flows	The number of current flows in the inbound direction (the traffic going into the VM)	Average	Count
Network In	The number of billable bytes received on all network interfaces by the VM(s)	Total	Bytes
Network Out	The number of outbound billable bytes on all network interfaces by the VMs (deprecated)	Total	Bytes
OS Disk Queue Depth	The depth or the length of the OS disk queue	Average	Count
OS Disk Read Bytes/sec	Bytes read from a single disk during the monitoring period for an OS disk	Average	Count per second
OS Disk Read Operations/Sec	Read IOPS from a single disk during the monitoring period for an OS disk	Average	Count per second
OS Disk Write Bytes/sec	Bytes written to a single disk during the monitoring period for an OS disk	Average	Count per second
OS Disk Write Operations/Sec	Write IOPS from a single disk during the monitoring period for an OS disk	Average	Count per second
Outbound Flows	The number of current outbound flows (the traffic going out of the VM)	Average	Count
Data Disk Queue Depth	The depth or the length of the data disk queue	Average	Count
Data Disk Read Bytes/sec	Bytes read from a single disk during the monitoring period	Average	Count per second
Data Disk Read Operations/Sec	Read IOPS from a single disk during the monitoring period	Average	Count per second
Data Disk Write Bytes/sec	Bytes written to a single disk during the monitoring period	Average	Count per second
Data Disk Write Operations/Sec	Write IOPS from a single disk during the monitoring period	Average	Count per second
Percentage CPU	The percentage of allocated compute units that are currently in use by the VM(s)	Average	Percentage

Threshold configuration

Global configuration

Go to the Admin section in the left navigation pane.
Select Configuration Profiles from the left pane and choose the Threshold and Availability (+) tab from the drop-down menu. Click Add Threshold Profile from the top-right corner.
Set the monitor type as Azure Virtual Machine Scale Sets. Now you can set the threshold values for all the metrics mentioned above.

Monitor-level configuration

Go to Cloud > Azure and select Azure Virtual Machine Scale Sets from the drop-down menu.
Choose a resource for which you would like to set a threshold, then click the hamburger icon . Select Edit, which will direct you to the Edit Azure Virtual Machine Scale Sets Monitor page.
You can set the threshold values for the metrics by selecting Threshold and Availability. You can also configure IT Automation at the attribute level.

IT Automation

Site24x7 offers a set of exclusive IT Automation tools to auto-resolve performance degradation issues. These tools react to events proactively rather than waiting for manual intervention.

Summary

The Summary tab will help you view metrics such as Data Disk Read and Write Bytes, Data Disk Read and Write Operations, Data Disk Queue Depth, and more.

Configuration Details

The Configuration Details tab provides the configuration details of your Virtual Machine Scale Set. Details on the Orchestration Mode, Provisioning State, Storage and Network Profile, and more are included in this section.

Dimension Metrics

Configure Dimension Metrics to view the dimension metric information. Get alerts by applying the respective dimension filter and configuring thresholds for them. You can apply thresholds in bulk for the metrics. Edit and delete the monitored dimension metrics using the Action option. You can also fetch the various dimensions for a preferred metric by providing the Dimension value while configuring the dimension metric. You can monitor up to 25 dimension metrics.

Instances

This tab lists the instances in your Virtual machine Scale Set along with the percentage of CPU used and the incoming and outgoing network information.

Outages

The Outages tab provides the history of the Virtual Machine Scale Set 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.
