Windows collects a range of performance metrics from the various system components. Each component amalgamates the performance metrics into a perf ormance object. The Uptime Infrastructure Monitor Windows agent collects the following metrics from the performance objects on a Windows system: CPU
Multi-CPU
Memory
System
Disk
Network
Process

Each set of performance metrics is averaged over an interval of one second.

CPU
The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system, and combines and averages all CPU statistics.
| Metric |
|---|
| Description | Performance Object | |
|---|---|---|
% User Time | The percentage of time that the processor spends in user mode (a processing mode for applications and subsystems). | Processor(_Total) |
% Privileged Time | The percentage of time that the processor in privileged mode, in which it has direct access to hardware and memory. | Processor(_Total) |
% Interrupt Time | The total amount that the processor uses to handle interrupts from applications or hardware. | Processor(_Total) |
Available KBytes | The amount of physical memory, in kilobytes, that is available. | Memory |
% Usage | The percentage of the paging file that is in use. | Paging File(_Total) |
Processor Queue Length | The number of queued threads that are waiting to be processed. | System |

Multi-CPU
The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system, per CPU.
| Metric |

|---|---|---|
% User Time | The percentage of time that the processor spends in user mode (a processing mode for applications and subsystems). | Processor (_Total) |
% System Time | The percentage of CPU kernel processes that are in use. | Processor (_Total) |
% |
Privileged Time | The percentage of time that the CPU spends executing kernel commands. | Processor (_Total) |
% |
Interrupt Time | The number of CPU interrupts. | Processor (_Total) |
Interrupts |
/sec | The rate at which CPU handles interrupts from applications or hardware each second. If the value for Interrupts/sec is high, there could be problems with the hardware on the system. | Processor (_Total) |
% Total | The total amount of % User Time, % Privileged Time, and % Interrupt Time | System |

Memory
The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system.
| Metric |
|---|
| Description | Performance Object |
|---|---|
Cache Faults |
/sec | The rate at which faults occurred when a page that was sought in the file system cache was not found and must be retrieved either from elsewhere in memory or from the disk. | Memory |
Pages Output/sec | The rate at which pages were written to disk to free space in physical memory. | Memory |
Page Writes |
/sec | The rate at which pages were written to disk to free space in physical memory. | Memory |
Pages/sec | The rate at which pages were read from or written to the disk in order to correct hard page faults. | Memory |
Pages Input |
/sec | The rate at which pages were read from disk to resolve hard page faults. | Memory |
Page Faults |
/sec | The average number of pages that are faulted each second. | Memory |
Transition Faults/sec | The rate at which page faults were resolved by recovering pages without additional disk activity. | Memory |

Disk
The Uptime Infrastructure Monitor agent outputs the metrics listed below for each individual physical disk on the system.
| Metric |

Bytes Received/sec | The rate, in seconds, at which bytes are received over a specific network adapter. | NetworkInterface (<interface>) |
Bytes Sent/sec | The rate, in seconds, at which bytes are sent over a specific network adapter. | NetworkInterface (<interface>) |
Packets Received Errors | The number of inbound packets that contained errors, which preventing those packets from being delivered to a higher-layer protocol. | NetworkInterface (<interface>) |
Packets Outbound Errors | The number of outbound packets that could not be transmitted because of errors. | NetworkInterface (<interface>) |
Segments Retransmitted/sec | The rate at which segments, which contain one or more bytes that have been previously transmitted, are sent again. | TCP |
