Key concepts

PATROL for Microsoft Azure Virtual Machines monitors services that are provided by Microsoft Azure for instance availability. It reports and monitors availability and performance across critical areas of Azure Services. It issues visual warnings and alarms when thresholds are exceeded, allowing easy identification of problem areas. It enables the event-based triggering of automatic user-supplied recovery or intervention actions.

Support for Microsoft Azure Virtual Machine Scale Sets service

PATROL for Microsoft Azure Virtual Machines supports monitoring of Azure Virtual Machine Scale Sets service. With this support, you can now monitor and manage the availability and performance of your Azure Virtual Machine Scale Sets. The KM provides information about the CPU, Memory, Disk, Process, and Network usage at host and instance level for this service. For information about how to configure the service for monitoring, see Configuring-Microsoft-Azure-Virtual-Machines-in-the-TrueSight-or-Central-Monitoring-Administration-console.

For a list of available attributes, see the following monitor types:

Service Principal based authentication to connect to Microsoft Azure

PATROL for Microsoft Azure now supports Service Principal based authentication to connect to the Microsoft Azure account. For information about how to use this authentication mechanism, see Configuring-Microsoft-Azure-Virtual-Machines-in-the-TrueSight-or-Central-Monitoring-Administration-console.

Virtual Machines Host metrics monitoring

PATROL for Microsoft Azure Virtual Machines now monitors performance of host virtual machines. The following metrics have been introduced to support this monitoring:

Monitor type	Attribute
Host-Metrics-PAF_VM_HOST_METRICS	CPU Credits Consumed (CPUCreditsConsumed) CPU Credits Remaining (CPUCreditsRemaining) Disk Read Bytes (DiskReadBytes) Disk Write Bytes (DiskWriteBytes) Disk Write Operations/Sec (DiskWriteOperationsSec) Disk Read Operations/Sec (DiskReadOperationsSec) Network In (NetworkIn) Network Out (NetworkOut) Percentage CPU (PercentageCPU)

The operating system related metrics are now available below the guest virtual machines.

Azure Virtual Machine Disk performance monitoring

PATROL for Microsoft Azure now monitors Azure Virtual Machine Logical Disk performance on Windows Virtual Machines. Along with this support, new metrics have been added to enhance Azure Virtual Machine Physical Disk performance. The following metrics have been introduced to support this feature.

Monitor type	Attribute
Azure-VM-Logical-Disk-PAF_LOGICAL_DISK	Average Disk Queue Length Average Disk Read Queue Length Average Disk Seconds Per Read Average Disk Seconds Per Transfer Average Disk Seconds Per Write Average Disk Write Queue Length Disk Bytes Per Second Disk Read Bytes Per Second Disk Reads Per Second Disk Transfers Per Second Disk Write Bytes Per Second Disk Writes Per Second Free Space(FreeSpace) Percent Disk Read Time Percent Disk Time Percent Disk Write Time Percent Free Space Percent Idle Time
Azure-VM-Physical-Disk-PAF_PHYSICAL_DISK	Percent Disk Read Time Percent Disk Time Percent Disk Write Time Percent Idle Time Disk Bytes Per Second Current Disk Queue Length

Azure-VM-Logical-Disk-PAF_LOGICAL_DISK

Azure-VM-Physical-Disk-PAF_PHYSICAL_DISK

Azure Virtual Machine Processor monitoring

PATROL for Microsoft Azure now measures various aspects of processor activity on Windows Virtual Machines. The following metrics have been introduced to support this monitoring:

Monitor type	Attribute
Azure-VM-Processor-Information-PAF_PROCESSOR_INFORMATION	Percent Privileged Time Processor Frequency Percent Processor Time Percent User Time
Azure-VM-System-PAF_SYSTEM	Context Switches Per Second Processes Processor Queue Length System Up Time

Usability enhancements

You can now view the performance metrics of guest virtual machines and host virtual machines in a distinct hierarchy on the TrueSight and the PATROL consoles. All the operating system performance metrics are now available below the guest (Guest OS Metrics monitor type) and the individual host metrics are available below the respective host (Host Metrics monitor type).
