Sample Server Performance Counter SLA Considerations
May 3, 2012Some of the Server System Characteristics to consider
|
Counter |
Description |
|
Processor% Processor Time |
% Processor Time is the percentage of time that the processor is executing a non-Idle thread |
|
Processor% Interrupt Time |
% Interrupt Time is the percentage of time the processor spent receiving and servicing hardware interrupts during the sample interval |
|
ProcessorInterrupts/sec |
Interrupts/sec is the average number of hardware interrupts the processor is receiving and servicing in each second |
|
SystemProcesses |
Processes is the number of processes in the computer at the time of data collection. |
|
TCPConnections Established |
Connections Established is the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. |
|
TCPSegments/sec |
Segments/sec is the rate at which TCP segments are sent or received using the TCP protocol. |
|
Process% Processor Time |
% Processor Time is the percentage of elapsed time that all of the threads of specified process used the processor to execute instructions. |
|
ProcessHandle Count |
The total number of handles currently open by specified process. |
|
Printer QueueJobs |
Current number of jobs in a print queue. |
|
PhysicalDisk% Disk Time |
% Disk Time is the percentage of elapsed time that the selected disk drive is busy servicing read or write requests. |
|
PhysicalDiskCurrent Disk Queue Length |
Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected |
|
MemoryAvailable Bytes |
Available Bytes is the amount of physical memory available to processes running on the computer, in bytes. |
|
NetworkInterfaceCurrent Bandwidth |
Current Bandwidth is an estimate of the interface current bandwidth in bits per second (BPS). |
