The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system, and combines and averages all CPU statistics.
| Metric | ExplanationDescription | 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 |

The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system, per CPU.
| Metric | ExplanationDescription | Performanc ePerformance Object |
|---|---|---|
% 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) |
% | The percentage of time that the CPU spends executing kernel commands. | Processor (_Total) |
% | The number of CPU interrupts. | Processor (_Total) |
Interrupts | 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 |

The Uptime Infrastructure Monitor agent outputs the metrics listed below for the entire system.
| Metric | ExplanationDescription | Performance Object |
|---|---|---|
Cache Faults | 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 | 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 | The rate at which pages were read from disk to resolve hard page faults. | Memory |
Page Faults | 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 |

The Uptime Infrastructure Monitor agent outputs the metrics listed below for each individual physical disk on the system.
| Metric | ExplanationDescription | Performance Object |
|---|---|---|
% Disk Time | The percentage of time during which the disk drive is handling read or write requests. | PhysicalDisk (<diskname>) |
Disk Transfers/sec | The number of read and write operations on the disk that occur each second. | PhysicalDisk (<diskname>) |
Avg. Disk Bytes | The average number of bytes that have been transferred to or from the disk during write or read operations. | PhysicalDisk (<diskname>) |
Disk Bytes/sec | The rate at which bytes are transferred to or from the disk during write or read operations. | PhysicalDisk (<diskname>) |
Avg. Disk sec/Transfer | The average amount of time, in seconds, that a disk transfer takes to complete. | PhysicalDisk (<diskname>) |
...
The Uptime Infrastructure Monitor agent outputs the metrics listed below for each individual network interface on the system.
| Metric | ExplanationDescription | Performance Object |
|---|---|---|
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 |
...
By default, the Uptime Infrastructure Monitor agent gathers the top 20 processes. These processes are sorted by highest CPU usage.
| Metric | ExplanationDescription | Performance Object |
|---|---|---|
ID Process | The unique identifier of a specific process. | Process(<processname>) |
Creating Process ID | The identifier of the process that the process that is currently running. | Process(<processname>) |
Virtual Bytes | The size, in bytes, of the virtual address space that a particular process is currently using. | Process(<processname>) |
Working Set | The maximum size, in bytes, of the working set of a particular process. | Process(<processname>) |
% Processor Time | The percentage of time that all of the threads of a process used the processor to execute instructions. | Process(<processname>) |
Elapsed Time | The total time, in seconds, that a process has been running. | Process(<processname>) |
