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%.

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.

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.

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.

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

in User mode.

The number of logical processors available on the computer.

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.

CPU utilization is too high. The system might be slow to respond.

"The CPU Interrupt Time in the last 5 minutes exceeds {$CPU.INTERRUPT.CRIT.MAX}%."

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

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.

Expression:

The free space of swap volume/file in percent.

Preprocessing:

- JAVASCRIPT: return (100 - value)

The used space of swap volume/file in percent.

The total space of swap volume/file in bytes.

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.

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.

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.

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.

The system is running out of free memory.

This trigger is ignored, if there is no swap configured

This trigger expression works as follows:

1. It can be triggered if the operations status is down.

2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.

3. {TEMPLATE_NAME:METRIC.diff()}=1) - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'ethernal off' interfaces.)
