Data Disk Target Bandwidth: The throughput limit that the data(s) disk can achieve without bursting.OS Disk Max Burst IOPS: The IOPS limit that the OS disk can burst up to.
Data Disk Max Burst IOPS: the IOPS limit that the data disk(s) can burst up to. OS Disk Max Burst Bandwidth: The throughput limit that the OS disk can burst up to. Data Disk Max Burst Bandwidth: The throughput limit that the data disk(s) can burst up to. The following metrics help with observability into our bursting feature on our premium disks: Disk Write Operations/Sec: The number of output operations that are written in a second from all disks attached to a VM. Disk Write Bytes/Sec: The number of bytes that are written in a second from all disks attached to a VM. Disk Read Operations/Sec: The number of input operations that are read in a second from all disks attached to a VM. Disk Read Bytes/Sec: The number of total bytes that are read in a second from all disks attached to a VM. Data Disk Write Operations/Sec: The number of output operations that are written in a second from data disk(s). Data Disk Write Bytes/Sec: The number of bytes that are written in a second from the data disk(s). Data Disk Read Operations/Sec: The number of input operations that are read in a second from data disk(s). Data Disk Read Bytes/Sec: The number of bytes that are read in a second from the data disk(s). Data Disk Queue Depth: The number of current outstanding IO requests that are waiting to be read from or written to the data disk(s). OS Disk Write Operations/Sec: The number of output operations that are written in a second from the OS disk. OS Disk Write Bytes/Sec: The number of bytes that are written in a second from the OS disk. OS Disk Read Operations/Sec: The number of input operations that are read in a second from the OS disk. OS Disk Read Bytes/Sec: The number of bytes that are read in a second from the OS disk. OS Disk Queue Depth: The number of current outstanding IO requests that are waiting to be read from or written to the OS disk. The following metrics are available to get insight on VM and Disk IO, throughput, and queue depth performance: Disk IO, throughput and queue depth metrics Storage IO utilization metrics - These metrics help diagnose bottlenecks in your storage performance with disks.Īll metrics are emitted every minute, except for the bursting credit percentage metric, which is emitted every 5 minutes. Disk bursting metrics - These are the metrics provide observability into our bursting feature on our premium disks. Disk IO, throughput and queue depth metrics - These metrics allow you to see the storage performance from the perspective of a disk and a virtual machine. This article is broken into 3 subsections: The metrics can also be retrieved through an API call. #Trim enabler vs disk sensei windows
Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale setsĪzure offers metrics in the Azure portal that provide insight on how your virtual machines (VM) and disks perform.
