Description: Informant Systems standard Windows host MIB providing baseline OS and hardware performance objects for SNMP monitoring.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is INFORMANT-STD?

INFORMANT-STD is an Informant Systems, Inc. proprietary MIB (built on WTCS) exposing standard Windows performance-counter data via SNMP — the SNMP Informant agent. Its logical-disk table, keyed by instance, mirrors the Windows PerfMon LogicalDisk object: percent disk read/write/total time, percent free/idle space, average disk queue length (total/read/write), average disk sec-per-read/transfer/write, current disk-queue length, disk bytes/reads/writes per second, free megabytes, and split-IO per second, alongside system memory-available counters. As a performance MIB it lets an administrator monitor Windows disk queue depth and free space per logical disk via SNMP using the SNMP Informant agent. It is deployed on Windows servers running the SNMP Informant agent. Engineers can download the INFORMANT-STD file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in INFORMANT-STD. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Windows servers running the SNMP Informant agent

Monitoring Examples

An administrator checks lDiskAvgDiskQueueLength and lDiskFreeMegabytes to monitor Windows disk performance via the SNMP Informant agent.

How to Use in IPNetwork Monitor

Example using memoryAvailableBytes OID:

Select a Windows server running the SNMP Informant agent (standard disk/memory counters) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type memoryAvailableBytes into the Find box to locate it in the OID tree, then select it and click OK. It reports the available Bytes is the amount of physical memory available to processes running on the computer, in bytes. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.

G32 lDiskPercentIdleTime	1.3.6.1.4.1.9600.1.1.1.1.6	Gauge32	read-only	% Idle Time reports the percentage of time during the sample interval that the disk was idle.
G32 lDiskAvgDiskQueueLength	1.3.6.1.4.1.9600.1.1.1.1.7	Gauge32	read-only	Avg. Disk Queue Length is the average number of both read and write requests that were queued for the selected disk during the sample interval. Multiplied by 1000 to provide a useful gauge value since it is commonly a fractional value.
G32 lDiskAvgDiskReadQueueLength	1.3.6.1.4.1.9600.1.1.1.1.8	Gauge32	read-only	Avg. Disk Read Queue Length is the average number of read requests that were queued for the selected disk during the sample interval. Multiplied by 1000 to provide a useful gauge value since it is commonly a fractional value.

G32 lDiskCurrentDiskQueueLength	1.3.6.1.4.1.9600.1.1.1.1.13	Gauge32	read-only	Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It includes requests in service at the time of the snapshot. This is an instantaneous length, not an average over the time interval. Multi-spindle disk devices can have multiple requests active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests are experiencing delays proportional to the length of this queue minus the number of spindles on the disks. This difference should average less than 2 for good performance.
G32 lDiskDiskBytesPerSec	1.3.6.1.4.1.9600.1.1.1.1.14	Gauge32	read-only	Disk Bytes/sec is the rate bytes are transferred to or from the disk during write or read operations.

G32 lDiskFreeMegabytes	1.3.6.1.4.1.9600.1.1.1.1.20	Gauge32	read-only	Free Megabytes displays the unallocated space on the disk drive in megabytes. One megabyte = 1,048,576 bytes.
G32 lDiskSplitIOPerSec	1.3.6.1.4.1.9600.1.1.1.1.21	Gauge32	read-only	Split IO/Sec reports the rate that I/Os to the disk were split into multiple I/Os. A split I/O may result from requesting data in a size that is too large to fit into a single I/O or that the disk is fragmented.
memory	1.3.6.1.4.1.9600.1.1.2			The Memory performance object consists of counters that describe the behavior of physical and virtual memory on the computer. Physical memory is the amount of random-access memory (RAM) on the computer. Virtual memory consists of space in physical memory and on disk. Many of the memory counters monitor paging, which is the movement of pages of code and data between disk and physical memory. Excessive paging, a symptom of a memory shortage, can cause delays which interfere with all system processes.
G32 memoryAvailableBytesEx	1.3.6.1.4.1.9600.1.1.2.1	Gauge32	read-only	Available Bytes is the amount of physical memory available to processes running on the computer, in bytes. It is calculated by summing space on the Zeroed, Free, and Stand by memory lists. Free memory is ready for use; Zeroed memory are pages of memory filled with zeros to prevent later processes from seeing data used by a previous process. Standby memory is memory removed from a process' working set (its physical memory) on route to disk, but is still available to be recalled. This counter displays the last observed value only; it is not an average.
G32 memoryAvailableKBytes	1.3.6.1.4.1.9600.1.1.2.2	Gauge32	read-only	Available KBytes is the amount of physical memory available to processes running on the computer, in Kilobytes (Bytes / 1,024). It is calculated by summing space on the Zeroed, Free, and Stand by memory lists. Free memory is ready for use; Zeroed memory are pages of memory filled with zeros to prevent later processes from seeing data used by a previous process. Standby memory is memory removed from a process' working set (its physical memory) on route to disk, but is still available to be recalled. This counter displays the last observed value only; it is not an average.
G32 memoryAvailableMBytes	1.3.6.1.4.1.9600.1.1.2.3	Gauge32	read-only	Available MBytes is the amount of physical memory available to processes running on the computer, in Megabytes (Bytes / 1,048,576). It is calculated by summing space on the Zeroed, Free, and Stand by memory lists. Free memory is ready for use; Zeroed memory are pages of memory filled with zeros to prevent later processes from seeing data used by a previous process. Standby memory is memory removed from a process' working set (its physical memory) on route to disk, but is still available to be recalled. This counter displays the last observed value only; it is not an average.
G32 memoryCommittedBytes	1.3.6.1.4.1.9600.1.1.2.4	Gauge32	read-only	Committed Bytes is the amount of committed virtual memory, in bytes. (Committed memory is physical memory for which space has been reserved on the disk paging file in case it needs to be written back to disk). This counter displays the last observed value only; it is not an average.
G32 memoryCacheBytes	1.3.6.1.4.1.9600.1.1.2.5	Gauge32	read-only	Cache Bytes is the sum of the System Cache Resident Bytes, System Driver Resident Bytes, System Code Resident Bytes, and Pool Paged Resident Bytes counters. This counter displays the last observed value only; it is not an average.
G32 memoryCacheBytesPeak	1.3.6.1.4.1.9600.1.1.2.6	Gauge32	read-only	Cache Bytes Peak is the maximum value of Cache Bytes since the system was last restarted. This value might be larger than the current size of the cache. Cache Bytes is the sum of the System Cache Resident Bytes, System Driver Resident Bytes, System Code Resident Bytes, and Pool Paged Resident Bytes counters. This counter displays the last observed value only; it is not an average.
G32 memoryPageFaultsPerSec	1.3.6.1.4.1.9600.1.1.2.7	Gauge32	read-only	Page Faults/sec is the overall rate faulted pages are handled by the processor. It is measured in numbers of pages faulted per second. A page fault occurs when a process requires code or data that is not in its working set (its space in physical memory). 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 consequence. However, hard faults can cause significant delays. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 memoryPagesInputPerSec	1.3.6.1.4.1.9600.1.1.2.8	Gauge32	read-only	Pages Input/sec is the number of pages read from disk to resolve hard page faults. (Hard page faults occur when a process requires code or data that is not in its working set or elsewhere in physical memory, and must be retrieved from disk). This counter was designed as a primary indicator of the kinds of faults that cause system-wide delays. It includes pages retrieved to satisfy faults in the file system cache (usually requested by applications) and in non-cached mapped memory files. This counter counts numbers of pages, and can be compared to other counts of pages, such as Memory: Page Faults/sec, without conversion. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 memoryPagesOutputPerSec	1.3.6.1.4.1.9600.1.1.2.9	Gauge32	read-only	Pages Output/sec is the number of pages written to disk to free up space in physical memory. Pages are written back to disk only if they are changed in physical memory, so they are likely to hold data, not code. A high rate of pages output might indicate a memory shortage. Windows NT writes more pages back to disk to free up space when physical memory is in short supply. This counter counts numbers of pages, and can be compared to other counts of pages, without conversion. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 memoryPagesPerSec	1.3.6.1.4.1.9600.1.1.2.10	Gauge32	read-only	Pages/sec is the number of pages read from or written to disk to resolve hard page faults. (Hard page faults occur when a process requires code or data that is not in its working set or elsewhere in physical memory, and must be retrieved from disk). This counter was designed as a primary indicator of the kinds of faults that cause system-wide delays. It is the sum of Memory: Pages Input/sec and Memory: Pages Output/sec. It is counted in numbers of pages, so it can be compared to other counts of pages, such as Memory: Page Faults/sec, without conversion. It includes pages retrieved to satisfy faults in the file system cache (usually requested by applications) non-cached mapped memory files. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 memoryPoolNonpagedBytes	1.3.6.1.4.1.9600.1.1.2.11	Gauge32	read-only	Pool Nonpaged Bytes is the number of bytes in the nonpaged pool, an area of system memory (physical memory used by the operating system) for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated. Memory: Pool Nonpaged Bytes is calculated differently than Process: Pool Nonpaged Bytes, so it might not equal Process: Pool Nonpaged Bytes: _Total. This counter displays the last observed value only; it is not an average.
G32 memoryPoolPagedBytes	1.3.6.1.4.1.9600.1.1.2.12	Gauge32	read-only	Pool Paged Bytes is the number of bytes in the paged pool, an area of system memory (physical memory used by the operating system) for objects that can be written to disk when they are not being used. Memory: Pool Paged Bytes is calculated differently than Process: Pool Paged Bytes, so it might not equal Process: Pool Paged Bytes: _Total. This counter displays the last observed value only; it is not an average.
G32 memoryPoolPagedResidentBytes	1.3.6.1.4.1.9600.1.1.2.13	Gauge32	read-only	Pool Paged Resident Bytes is the current size of paged pool in bytes. The paged pool is an area of system memory (physical memory used by the operating system) for objects that can be written to disk when they are not being used. Space used by the paged and nonpaged pools are taken from physical memory, so a pool that is too large denies memory space to processes. This counter displays the last observed value only; it is not an average.
G32 memorySystemCacheResidentBytes	1.3.6.1.4.1.9600.1.1.2.14	Gauge32	read-only	System Cache Resident Bytes is the number of bytes from the file system cache that are resident in physical memory. This value includes only current physical pages and does not include any virtual memory pages not currently resident. As such this value may be smaller than the actual amount of virtual memory in use by the file system cache. This value is a component of Memory: System Code Resident Bytes. This counter displays the last observed value only; it is not an average.
G32 memorySystemCodeResidentBytes	1.3.6.1.4.1.9600.1.1.2.15	Gauge32	read-only	System Code Resident Bytes is the number of bytes of operating system code currently in physical memory that can be written to disk when not in use. This value is a component of System Code Total Bytes, which also includes operating system code on disk. System Code Resident Bytes (and System Code Total Bytes) does not include code that must remain in physical memory and cannot be written to disk. This counter displays the last observed value only; it is not an average.
G32 memorySystemCodeTotalBytes	1.3.6.1.4.1.9600.1.1.2.16	Gauge32	read-only	System Code Total Bytes is the number of bytes of pageable operating system code currently in virtual memory. It is a measure of the amount of physical memory being used by the operating system that can be written to disk when not in use. This value is calculated by summing the bytes in Ntoskrnl.exe, Hal.dll, the boot drivers, and file systems loaded by Ntldr/osloader. This counter does not include code that must remain in physical memory and cannot be written to disk. This counter displays the last observed value only; it is not an average.

It is the working set (physical memory area) of the drivers. This value is a component of Memory: System Driver Total Bytes, which also includes driver memory that has been written to disk. Neither System Driver Resident Bytes nor System Driver Total Bytes includes memory that cannot be written to disk.
G32 memorySystemDriverTotalBytes	1.3.6.1.4.1.9600.1.1.2.18	Gauge32	read-only	System Driver Total Bytes is the number of bytes of pageable virtual memory currently being used by device drivers. (Pageable memory can be written to disk when it is not being used). It includes physical memory (Memory: System Driver Resident Bytes) and code and data paged to disk. It is a component of Memory: System Code Total Bytes. This counter displays the last observed value only; it is not an average.
G32 memoryCommittedKBytes	1.3.6.1.4.1.9600.1.1.2.19	Gauge32	read-only	Committed KiloBytes is the amount of committed virtual memory, in kilobytes. Committed memory is the physical memory which has space reserved on the disk paging file(s). There can be one or more paging files on each physical drive. This counter displays the last observed value only; it is not an average.

This counter displays the last observed value only; it is not an average.
G32 memoryCacheKBytesPeak	1.3.6.1.4.1.9600.1.1.2.21	Gauge32	read-only	Cache KiloBytes Peak is the maximum number of kilobytes used by the file system cache since the system was last restarted. This might be larger than the current size of the cache. This counter displays the last observed value only; it is not an average.

The paged pool is an area of system memory (physical memory used by the operating system) for objects that can be written to disk when they are not being used. Space used by the paged and nonpaged pools are taken from physical memory, so a pool that is too large denies memory space to processes.

This value includes only current physical pages and does not include any virtual memory pages not currently resident. It does equal the System Cache value shown in Task Manager. As a result, this value may be smaller than the actual amount of virtual memory in use by the file system cache. This value is a component of Memory\\System Code Resident KiloBytes which represents all pageable operating system code that is currently in physical memory. This counter displays the last observed value only; it is not an average.

objects	1.3.6.1.4.1.9600.1.1.4			The Objects performance object consists of counters that monitor logical objects in the system, such as processes, threads, mutexes, and semaphores. This information can be used to detect the unnecessary consumption of computer resources. Each object requires memory to store basic information about the object.
G32 objectsProcesses	1.3.6.1.4.1.9600.1.1.4.1	Gauge32	read-only	Processes is the number of processes in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. Each process represents the running of a program.
G32 objectsThreads	1.3.6.1.4.1.9600.1.1.4.2	Gauge32	read-only	Threads is the number of threads in the computer at the time of data collection. Notice that this is an instantaneous count, not an average over the time interval. A thread is the basic executable entity that can execute instructions in a processor.
processorTable	1.3.6.1.4.1.9600.1.1.5		not-accessible	The Processor performance object consists of counters that measure aspects of processor activity. The processor is the part of the computer that performs arithmetic and logical computations, initiates operations on peripherals, and runs the threads of processes. A computer can have multiple processors. The processor object represents each processor as an instance of the object.
processorEntry	1.3.6.1.4.1.9600.1.1.5.1		not-accessible	Performance information for one particular instance of 'Processor' object.

G32 cpuPercentDPCTime	1.3.6.1.4.1.9600.1.1.5.1.2	Gauge32	read-only	% DPC Time is the percentage of time that the processor spent receiving and servicing deferred procedure calls (DPCs) during the sample interval. (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. They are counted separately and are not a component of the interrupt counters. This counter displays the average busy time as a percentage of the sample time.
G32 cpuPercentInterruptTime	1.3.6.1.4.1.9600.1.1.5.1.3	Gauge32	read-only	% Interrupt Time is the percentage of time the processor spent receiving and servicing hardware interrupts during the sample interval. 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. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the average busy time as a percentage of the sample time.
G32 cpuPercentPrivilegedTime	1.3.6.1.4.1.9600.1.1.5.1.4	Gauge32	read-only	% Privileged Time is the percentage of non-idle processor time spent in privileged mode. (Privileged mode is a processing mode designed for operating system components and hardware-manipulating drivers. It allows direct access to hardware and all memory. The alternative, user mode, is a restricted processing mode designed for applications, environment subsystems, and integral subsystems. The operating system switches application threads to privileged mode to access operating system services). % Privileged Time includes time servicing interrupts and DPCs. A high rate of privileged time might be attributable to a large number of interrupts generated by a failing device. This counter displays the average busy time as a percentage of the sample time.
G32 cpuPercentProcessorTime	1.3.6.1.4.1.9600.1.1.5.1.5	Gauge32	read-only	% Processor Time is the percentage of time that the processor is executing a non-Idle thread. This counter was designed as a primary indicator of processor activity. It is calculated by measuring the time that the processor spends executing the thread of the Idle process in each sample interval, and subtracting that value from 100%. (Each processor has an Idle thread which consumes cycles when no other threads are ready to run). It can be viewed as the percentage of the sample interval spent doing useful work. This counter displays the average percentage of busy time observed during the sample interval. It is calculated by monitoring the time the service was inactive, and then subtracting that value from 100%.
G32 cpuPercentUserTime	1.3.6.1.4.1.9600.1.1.5.1.6	Gauge32	read-only	% User Time is the percentage of non-idle processor time spent in user mode. (User mode is a restricted processing mode designed for applications, environment subsystems, and integral subsystems. The alternative, privileged mode, is designed for operating system components and allows direct access to hardware and all memory. The operating system switches application threads to privileged mode to access operating system services). This counter displays the average busy time as a percentage of the sample time.
G32 cpuAPCBypassesPerSec	1.3.6.1.4.1.9600.1.1.5.1.7	Gauge32	read-only	APC Bypasses/sec is the rate at which Kernel APC interrupts were avoided. APC Bypasses/sec is the rate at which kernel APC interrupts were short-circuited. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 cpuDPCBypassesPerSec	1.3.6.1.4.1.9600.1.1.5.1.8	Gauge32	read-only	DPC Bypasses/sec is the rate at which deferred procedure calls (DPCs) on all processors were avoided. (DPCs are interrupts that run at a lower priority than standard interrupts). This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 cpuDPCRate	1.3.6.1.4.1.9600.1.1.5.1.9	Gauge32	read-only	DPC Rate is the rate at which deferred procedure calls (DPCs) are added to the processor's DPC queue between the timer ticks of the processor clock. (DPCs are interrupts that run at a lower priority than standard interrupts. Each processor has its own DPC queue). This counter measures the rate at which DPCs are added to the queue, not the number of DPCs in the queue. This counter displays the last observed value only; it is not an average.
G32 cpuDPCsQueuedPerSec	1.3.6.1.4.1.9600.1.1.5.1.10	Gauge32	read-only	DPCs Queued/sec is the overall rate at which deferred procedure calls (DPCs) are added to the processor's DPC queue. (DPCs are interrupts that run at a lower priority than standard interrupts. Each processor has its own DPC queue). This counter measures the rate at which DPCs are added to the queue, not the number of DPCs in the queue. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
G32 cpuInterruptsPerSec	1.3.6.1.4.1.9600.1.1.5.1.11	Gauge32	read-only	Interrupts/sec is the average number of hardware interrupts the processor is receiving and servicing in each second. It does not include DPCs, which are counted separately. 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. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
system	1.3.6.1.4.1.9600.1.1.6			The System performance object consists of counters that apply to more than one component of the computer. Percentage counters by default do not show values above 100 percent. See 'Overview of Performance Monitoring' in the Windows 2000 Server Resource Kit Server Operations Guide for instructions about changing this default in the registry.
G32 systemSystemUpTime	1.3.6.1.4.1.9600.1.1.6.1	Gauge32	read-only	System Up Time is the elapsed time (in seconds) that the computer has been running since it was last started. This counter displays the difference between the start time and the current time.
