The agent always returns 1 for this item. It could be used in combination with nodata() for availability check.

 Zabbix agent agent.ping
Windows: Zabbix agent availability

Monitoring the availability status of the agent.

 Zabbix internal zabbix[host,agent,available]
Windows: CPU utilization

The CPU utilization expressed in %.

 Zabbix agent system.cpu.util
Windows: CPU interrupt time

The Processor Information% Interrupt Time is the time the processor spends receiving and servicing

hardware interrupts during sample intervals. This value is an indirect indicator of the activity of

devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication

lines, network interface cards and other peripheral devices. This is an easy way to identify a potential

hardware failure. This should never be higher than 20%.

 Zabbix agent perf_counter_en["\Processor Information(_total)% Interrupt Time"]
Windows: Context switches per second

Context Switches/sec is the combined rate at which all processors on the computer are switched from one thread to another.

Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher priority ready thread, or switches between user-mode and privileged (kernel) mode to use an Executive or subsystem service.

It is the sum of Thread\Context Switches/sec for all threads running on all processors in the computer and is measured in numbers of switches.

There are context switch counters on the System and Thread objects. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.

 Zabbix agent perf_counter_en["\System\Context Switches/sec"]
Windows: CPU privileged time

The Processor Information% Privileged Time counter shows the percent of time that the processor is spent

executing in Kernel (or Privileged) mode. Privileged mode includes services interrupts inside Interrupt

Service Routines (ISRs), executing Deferred Procedure Calls (DPCs), Device Driver calls and other kernel-mode

functions of the Windows® Operating System.

 Zabbix agent perf_counter_en["\Processor Information(_total)% Privileged Time"]
Windows: CPU DPC time

Processor DPC time is the time that a single processor spent receiving and servicing deferred procedure

calls (DPCs). DPCs are interrupts that run at a lower priority than standard interrupts. % DPC Time is a

component of % Privileged Time because DPCs are executed in privileged mode. If a high % DPC Time is

sustained, there may be a processor bottleneck or an application or hardware related issue that can

significantly diminish overall system performance.

 Zabbix agent perf_counter_en["\Processor Information(_total)% DPC Time"]
Windows: CPU user time

The Processor Information% User Time counter shows the percent of time that the processor(s) is spent executing

in User mode.

 Zabbix agent perf_counter_en["\Processor Information(_total)% User Time"]
Windows: Number of cores

The number of logical processors available on the computer.

 Zabbix agent wmi.get[root/cimv2,"Select NumberOfLogicalProcessors from Win32_ComputerSystem"]
Windows: CPU queue length

The Processor Queue Length shows the number of threads that are observed as delayed in the processor Ready Queue

and are waiting to be executed.

 Zabbix agent perf_counter_en["\System\Processor Queue Length"]
Windows: Used memory

Used memory in bytes.

 Zabbix agent vm.memory.size[used]
Windows: Total memory

The total memory expressed in bytes.

 Zabbix agent vm.memory.size[total]
Windows: Memory utilization

Memory utilization in %.

 Calculated vm.memory.util
Windows: Cache bytes

Cache Bytes is the sum of the Memory\System Cache Resident Bytes, Memory\System Driver Resident Bytes,

Memory\System Code Resident Bytes, and Memory\Pool Paged Resident Bytes counters. This counter displays

the last observed value only; it is not an average.

 Zabbix agent perf_counter_en["\Memory\Cache Bytes"]
Windows: Free swap space

The free space of the swap volume/file expressed in bytes.

 Calculated system.swap.free
Windows: Free swap space in %

The free space of the swap volume/file expressed in %.

 Dependent item system.swap.pfree

Preprocessing

  • JavaScript: return (100 - value)
Windows: Used swap space in %

The used space of swap volume/file in percent.

 Zabbix agent perf_counter_en["\Paging file(_Total)% Usage"]
Windows: Total swap space

The total space of the swap volume/file expressed in bytes.

 Zabbix agent system.swap.size[,total]
Windows: Free system page table entries

This indicates the number of page table entries not currently in use by the system. If the number is less

than 5,000, there may well be a memory leak or you running out of memory.

 Zabbix agent perf_counter_en["\Memory\Free System Page Table Entries"]
Windows: Memory page faults per second

Page Faults/sec is the average number of pages faulted per second. It is measured in number of pages

faulted per second because only one page is faulted in each fault operation, hence this is also equal

to the number of page fault operations. This counter includes both hard faults (those that require

disk access) and soft faults (where the faulted page is found elsewhere in physical memory.) Most

processors can handle large numbers of soft faults without significant consequence. However, hard faults,

which require disk access, can cause significant delays.

 Zabbix agent perf_counter_en["\Memory\Page Faults/sec"]
Windows: Memory pages per second

This measures the rate at which pages are read from or written to disk to resolve hard page faults.

If the value is greater than 1,000, as a result of excessive paging, there may be a memory leak.

 Zabbix agent perf_counter_en["\Memory\Pages/sec"]
Windows: Memory pool non-paged

This measures the size, in bytes, of the non-paged pool. This is an area of system memory for objects

that cannot be written to disk but instead must remain in physical memory as long as they are allocated.

There is a possible memory leak if the value is greater than 175MB (or 100MB with the /3GB switch).

A typical Event ID 2019 is recorded in the system event log.

 Zabbix agent perf_counter_en["\Memory\Pool Nonpaged Bytes"]
