|Windows: CPU utilization|<p>The CPU utilization expressed in %.</p>|Zabbix agent (active)|system.cpu.util|
|Windows: CPU interrupt time|<p>The Processor Information\% Interrupt Time is the time the processor spends receiving and servicing</p><p>hardware interrupts during sample intervals. This value is an indirect indicator of the activity of</p><p>devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication</p><p>lines, network interface cards and other peripheral devices. This is an easy way to identify a potential</p><p>hardware failure. This should never be higher than 20%.</p>|Zabbix agent (active)|perf_counter_en["\Processor Information(_total)\% Interrupt Time"]|
|Windows: Context switches per second|<p>Context Switches/sec is the combined rate at which all processors on the computer are switched from one thread to another.</p><p>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.</p><p>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.</p><p>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.</p>|Zabbix agent (active)|perf_counter_en["\System\Context Switches/sec"]|
|Windows: CPU privileged time|<p>The Processor Information\% Privileged Time counter shows the percent of time that the processor is spent</p><p>executing in Kernel (or Privileged) mode. Privileged mode includes services interrupts inside Interrupt</p><p>Service Routines (ISRs), executing Deferred Procedure Calls (DPCs), Device Driver calls and other kernel-mode</p><p>functions of the Windows® Operating System.</p>|Zabbix agent (active)|perf_counter_en["\Processor Information(_total)\% Privileged Time"]|
|Windows: CPU DPC time|<p>Processor DPC time is the time that a single processor spent receiving and servicing deferred procedure</p><p>calls (DPCs). DPCs are interrupts that run at a lower priority than standard interrupts. % DPC Time is a</p><p>component of % Privileged Time because DPCs are executed in privileged mode. If a high % DPC Time is</p><p>sustained, there may be a processor bottleneck or an application or hardware related issue that can</p><p>significantly diminish overall system performance.</p>|Zabbix agent (active)|perf_counter_en["\Processor Information(_total)\% DPC Time"]|
|Windows: CPU user time|<p>The Processor Information\% User Time counter shows the percent of time that the processor(s) is spent executing</p><p>in User mode.</p>|Zabbix agent (active)|perf_counter_en["\Processor Information(_total)\% User Time"]|

This counter displays</p><p>the last observed value only; it is not an average.</p>|Zabbix agent (active)|perf_counter_en["\Memory\Cache Bytes"]|
|Windows: Free swap space|<p>The free space of the swap volume/file expressed in bytes.</p>|Calculated|system.swap.free|
|Windows: Free swap space in %|<p>The free space of the swap volume/file expressed in %.</p>|Dependent item|system.swap.pfree<p>**Preprocessing**</p><ul><li><p>JavaScript: `return (100 - value)`</p></li></ul>|

|Windows: Free system page table entries|<p>This indicates the number of page table entries not currently in use by the system. If the number is less</p><p>than 5,000, there may well be a memory leak or you running out of memory.</p>|Zabbix agent (active)|perf_counter_en["\Memory\Free System Page Table Entries"]|
|Windows: Memory page faults per second|<p>Page Faults/sec is the average number of pages faulted per second. It is measured in number of pages</p><p>faulted per second because only one page is faulted in each fault operation, hence this is also equal</p><p>to the number of page fault operations. This counter includes both hard faults (those that require</p><p>disk access) and soft faults (where the faulted page is found elsewhere in physical memory.) Most</p><p>processors can handle large numbers of soft faults without significant consequence. However, hard faults,</p><p>which require disk access, can cause significant delays.</p>|Zabbix agent (active)|perf_counter_en["\Memory\Page Faults/sec"]|
|Windows: Memory pages per second|<p>This measures the rate at which pages are read from or written to disk to resolve hard page faults.</p><p>If the value is greater than 1,000, as a result of excessive paging, there may be a memory leak.</p>|Zabbix agent (active)|perf_counter_en["\Memory\Pages/sec"]|
|Windows: Memory pool non-paged|<p>This measures the size, in bytes, of the non-paged pool. This is an area of system memory for objects</p><p>that cannot be written to disk but instead must remain in physical memory as long as they are allocated.</p><p>There is a possible memory leak if the value is greater than 175MB (or 100MB with the /3GB switch).</p><p>A typical Event ID 2019 is recorded in the system event log.</p>|Zabbix agent (active)|perf_counter_en["\Memory\Pool Nonpaged Bytes"]|
