Dynamic Computer Metrics

Values for these metrics are sampled at regular intervals. The sampling interval is controlled by the parameter ProcessStatInterval.

The peak and low values are calculated over an entire delivery interval—not a report interval.

Parameter

Description

PeakCPUUsage

The percentage of time where the CPU was busy in the busiest sample interval. Derived from the % Processor Time Windows performance counter.

AverageCPUUsage

The percentage of time where the CPU has been busy in an entire delivery interval.

LowFreePhysicalMemory

Amount of physical memory available. Reported by the Win32 API function GlobalMemoryStatus(), in the sample interval with the least available physical memory.

AverageFreePhysicalMemory

The amount of physical memory available. Reported by the Win32 API function GlobalMemoryStatus(), averaged over all sample intervals in a delivery interval.

LowFreePagingFile

Amount of available paging file memory to commit. Reported by the Win32 API function GlobalMemoryStatus().

AverageFreePagingFile

Average amount of free paging file memory. Reported by the Win32 API function GlobalMemoryStatus().

LowVirtualMemory

Amount of unreserved and uncommitted memory in the user mode portion of the virtual address space of the calling process. Reported by the Win32 API function GlobalMemoryStatus() in the sample interval with the least amount.

AverageFreeVirtualMemory

Amount of unreserved and uncommitted memory in the user mode portion of the virtual address space of the calling process. Reported by the Win32 API function GlobalMemoryStatus() averaged over all sample intervals in a delivery interval.

AverageDiskWrites

The average disk byte write frequency. Derived from the Windows performance counter Disk Write Bytes/sec for the PhysicalDisk(_Total) object, calculated over an entire delivery interval.

AverageDiskReads

The average disk byte read frequency. Derived from the Windows performance counter Disk Read Bytes/sec for the PhysicalDisk(_Total) object, calculated over an entire delivery interval.

PeakDiskWrites

The disk byte write frequency. Derived from the Windows performance counter Disk Write Bytes/sec for the PhysicalDisk(_Total) object, in the sample interval with the highest rate.

PeakDiskReads

The disk byte read frequency. Derived from the Windows performance counter Disk Read Bytes/sec for the PhysicalDisk(_Total) object, in the sample interval with the highest rate.

Server Metrics (the following metrics are only measured if ServerMetrics is enabled in the agent configuration)


Average Contextswitches

The average number of context switches for the system, derived from the Context Switches/sec counter for System performance counter object.

Peak Contextswitches

The number of context switches for the system, derived from the Context Switches/sec counter for System performance counter object, in the sample interval with the highest rate.

Average Send Bytes (NIC)

The average number of bytes that the computer sends on the Network Interface Card (NIC) that the agent is monitoring. Derived from the Bytes Sent/sec counter on the Network Interface performance object.

Peak Send Bytes (NIC)

The number of bytes that the computer sends on the Network Interface Card (NIC) that the agent is monitoring, during the busiest sampling interval. Derived from the Bytes Sent/sec counter on the Network Interface performance object.

Average Received Bytes (NIC)

The average number of bytes that the computer receives on the Network Interface Card (NIC) that the agent is monitoring. Derived from the Bytes Received/sec counter on the Network Interface performance object.

Peak Received Bytes (NIC)

The number of bytes that the computer receives on the Network Interface Card (NIC) that the agent is monitoring, during the busiest sampling interval. Derived from the Bytes Received/sec counter on the Network Interface performance object.
