Azure Disk Monitoring Integration

Azure disks are block-level storage volumes that are used with Azure Virtual Machines. Azure provides exclusive disk storage that can be attached to a virtual machine (VM) and can be used as a primary operating system (OS) disk, data disk, or both. These disks are virtualized versions of real disks on the on-premises servers.

With Site24x7's integration, you can now monitor your OS and data disks with accurate metrics, configure thresholds, and get instant alerts if there is a breach.

Setup and configuration

Adding an Azure disk while configuring a new Azure monitor

If you haven't configured an Azure Monitor yet, add one by following the steps below:

Log in to your Site24x7 account.
Choose Cloud from the left navigation pane, and select Azure > Add Azure Monitor. You can also follow these steps to add an Azure Monitor.
During Azure monitor configuration, in the Edit Azure Monitor page, select Azure Disk from the Service/Resource Types drop-down.

Adding an Azure disk to an existing Azure monitor

If you already have an Azure monitor configured for the tenant, you can add the Azure disk using the following steps:

Log in to your Site24x7 account.
Navigate to Cloud > Azure > select the Azure monitor from the left pane for which you wish to add an Azure disk.
In the Service View page, click the Enable Monitoring button on the Service type that you would like to add. In this case, click the Enable Monitoring button in the Azure Disk Service type.
It will take 15-30 minutes to discover new Azure resources. To immediately discover the selected configuration, click Discover Now in the top-right corner.

After successful addition, go to Cloud > Azure and select Azure Disk from the Azure monitor drop-down. Now, you can view the discovered disks.

Polling frequency

Site24x7's Azure Disk monitor collects metric data every minute and the statuses from your disks every five minutes.

Supported metrics

Site24x7 supports metric monitoring for Azure's basic metrics, as well as in-depth metrics of data disks and OS disks by tracking the VM that manages the disk.

Azure Preview metrics

Metric	Description	Statistic	Unit
Disk Read Bytes/Sec (Preview)	The amount of bytes read from the disk during the monitoring period.	Average	Bytes per second
Disk Read Operations/Sec (Preview)	The number of read IOs (input-outputs) performed on a disk during the monitoring period.	Average	Count per second

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 Disk 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 disk capacity is not overutilized, thus maintaining optimal storage and performance. This also helps in reducing costs by getting alerts for unusual changes in your disks. The default thresholds are as follows:

Alert if Disk is not attached (Idle Disk)
Alert if Storage Type is Changed
Alert if Disk Size is Changed
Alert if Disk IOPS Size is Changed
Alert if Disk throughput is Changed
Alert if Public Network Access is Changed
Alert if Performance Tier is Changed
Alert if Connected VM is Changed
Data Disk Bandwidth Consumed Percentage
Data Disk IOPS Consumed Percentage
Data Disk Used Burst BPS Credits Percentage
Data Disk Used Burst IO Credits Percentage
OS Disk Bandwidth Consumed Percentage
OS Disk IOPS Consumed Percentage
OS Disk Used Burst BPS Credits Percentage
OS Disk Used Burst IO Credits Percentage

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. IT Automation tools help automate repetitive tasks and automatically remediate threshold breaches. The alarms 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 adding 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 continuously track configuration changes and achieve the ideal configuration settings.

How to add a configuration rule.
