Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.

To view the health score for Azure Virtual Machine Scale Set entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select azurevirtualmachinescaleset.

Percentage CPU. The percentage of allocated compute units that are currently in use by the VM(s).

The number of successful read operations from the data disk cache. A higher value indicates efficient caching performance.

The number of read operations that were not found in the data disk cache, requiring retrieval from the underlying storage.

The number of successful read operations from the OS disk cache, improving performance by reducing direct disk access.

The number of read operations that were not found in the OS disk cache, leading to additional disk access.

The number of outstanding I/O requests waiting to be read from or written to the data disk in a Virtual Machine Scale Set (VMSS). A higher queue depth may indicate disk contention or performance bottlenecks.

Data Disk Read. The average number of bytes per second read from a single disk during the monitoring period.

The total number of read operations performed on the data disk in a VMSS. This metric helps monitor disk activity and performance.

Data Disk Write. The average number of bytes per second written to a single disk during the monitoring period.

The total number of write operations performed on the data disk in a VMSS. This metric is useful for analyzing disk activity and optimizing performance.

The number of outstanding I/O requests waiting to be read from or written to the OS disk in a VMSS. A higher queue depth may indicate disk contention or performance bottlenecks.

The total number of bytes read from the OS disk in a VMSS over a given period. This metric helps monitor disk read performance and workload patterns.

The total number of read operations performed on the OS disk in a VMSS. This metric provides insight into overall disk activity and utilization.

Tracks the total number of bytes written to the OS disk in a Virtual Machine Scale Set (VMSS). This metric helps monitor disk write performance and workload patterns.

The total number of write operations performed on the OS disk in a VMSS. This metric provides insight into overall disk activity and utilization.

Disk Read. The total number of bytes read from disk during the monitoring period.

Disk Read Operations. The average number of input operations read in a second from all disks attached to the VM(s).

Disk Write. The total number of bytes written to disk during the monitoring period.

Disk Write Operations. The average number of output operations written in a second to all disks attached to the VM(s).

Available Memory Bytes. The amount of physical memory, in bytes, immediately available for allocation to a process or for system use in the VM(s).

The number of inbound network flows to a VMSS instance. This metric helps monitor network traffic and connection patterns.

The maximum rate at which inbound network flows are created for a VMSS instance. This metric helps assess network performance and connection handling.

The number of outbound network flows from a VMSS instance. This metric helps monitor outgoing connections and network activity.

The maximum rate at which outbound network flows are created for a VMSS instance. This metric helps assess network performance and connection handling.

Network In Total. The number of bytes received on all network interfaces by the VM(s) (incoming traffic).

Network Out Total. The number of bytes out on all network interfaces by the VM(s) (outgoing traffic).
