Operating System InformationThe Performance Monitor Agent provides statistics and allows thresholds
to be set for various system performance parameters. Information is available
for the following subsystems: System, Server, Processor,
Memory, Paging File, Cache, Physical Disk,
Logical Disk, Network, TCP and Processes. The Performance Monitor Agent is a sub agent of the Foundation Agents.
This agent replaces the previous OS Management Agent (Patrol for Compaq)
and the previous threshold settings are not maintained. The agent obtains
performance
data from the Microsoft OS-supported Windows Management Information (WMI).
WMI is installed as part of the OS on Microsoft Server 2003 and Windows
2000. For Microsoft Windows NT4, WMI must be installed by the user. The install status of the Performance Monitor Agent is verified from
Start
Settings
Control Panel under the services section
of the HP Management Agents Control Panel applet. If needed, to activate
the Performance Monitor feature, select Performance
Monitor from the Inactive Agents section and
click the [Add] button. The Performance Monitor information
then is displayed under Active Agents section. Disk MonitoringTo enable physical and logical disk monitoring on Windows NT and Windows
2000 systems the command must be run:
DISKPERF [-Y[D|V] | -N[D|V]] [\\computername]
-Y
sets the system to start all disk performance counters when the system
is restarted.
-YD
enables the disk performance counters for physical drives, when the system
is restarted.
-YV
enables the disk performance counters for logical drives or storage volumes
when the system is restarted.
-N
sets the system to disable all disk performance counters when the system
is restarted.
-ND
disables the disk performance counters for physical drives
-NV
disables the disk performance counters for logical drives.
\\computername
is the name of the computer you want to see or set disk performance counter
use.
For Windows 2000, Disk Performance Monitoring can be turned on/off as
needed by using this command. For Windows NT4, Disk Performance Monitoring cannot be turned off once
it is turned on. For Windows Server 2003, Disk Performance Monitoring is on by default
and cannot be turned off. Threshold Alarms Warning and critical threshold limits can be set for the properties
where indicated in the list below. Alarms
are sent when the performance property value meets the threshold conditions
and stays for 15 data collection intervals. The data collection interval
is set in the HP Management Agents Control Panel applet under Windows
Control Panel Settings. Alarms are sent to the configured destinations
through SNMP and e-mail. In order to set thresholds, the user must have Administrator Rights
and have READ-WRITE or READ-CREATE
access in the SNMP security settings.
Alarm Monitoring Time Interval - 15
data collection intervals.
Performance Status iconsPerformance status icons are displayed next to those performance items
with adjustable thresholds (indicated
by the UNKNOWN, OK, DEGRADED
, or FAILED status icons) Supported OS Performance Properties. Information Availability to a WMI ConsumerFor Windows 2000, the formatted OS performance data is available by
registering a Windows WMI provider that supplies the formatted final OS
performance data. The data is populated in WMI under the specific classes
as follows:
Object Class: CPQ_System_Performance
Sub-classes:
CPQ_Tcp (CPQ_Tcpv4 for .net)
Under .net, the formatted data is also available under the WMI CIMV2
namespace as:
Sub-classes of: CIM_StatisticalInformation\Win32_Perf\Win32_PerfFormattedData
Memory
Available KBytes -
Amount of physical memory
available to processes running on the computer. It is calculated by summing
space on the Zeroed, Free, and Stand-by memory lists. Free memory is ready
for use. Zeroed memory is memory filled with zeros to prevent later processes
from seeing data used by a previous process. Standby memory is memory
removed from a working set (its physical memory) of a process enroute
to disk, but is still available to be recalled. This counter displays
the last observed value only; it is not an average. OID: 1.3.6.1.4.1.232.19.2.4.2 - cpqOsMemAvailableKBytes
Pages/sec -
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 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) and in 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. OID: 1.3.6.1.4.1.232.19.2.4.3 - cpqOsMemPagesPerSec
Pages Input/sec - 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 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. OID: 1.3.6.1.4.1.232.19.2.4.4 - cpqOsMemPagesInputPerSec
Pages Output/sec -
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. OID: 1.3.6.1.4.1.232.19.2.4.5 - cpqOsMemPagesOutputPerSec
Page Reads/sec -
Number of times the disk was
read 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 reads to satisfy
faults in the file system cache (usually requested by applications) and
in non-cached mapped memory files. This
counter counts numbers of read operations, without regard to the numbers
of pages retrieved by each operation. This
counter displays the difference between the values observed in the last
two samples, divided by the duration of the sample interval. OID: 1.3.6.1.4.1.232.19.2.4.8 - cpqOsMemPageReadsPerSecx1000
Page Writes/sec - Number of times pages were
written to disk to free up space in physical memory. Pages
are written to disk only if they are changed while in physical memory,
so they are likely to hold data, not code. This
counter counts write operations, without regard to the number of pages
written in each operation. This
counter displays the difference between the values observed in the last
two samples, divided by the duration of the sample interval. OID: 1.3.6.1.4.1.232.19.2.4.9 - cpqOsMemPageWritesPerSecx1000
Page Faults/sec - Overall rate at which the
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. OID: 1.3.6.1.4.1.232.19.2.4.6 - cpqOsMemPageFaultsPerSec
Cache Bytes - 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. OID: 1.3.6.1.4.1.232.19.2.4.11 - cpqOsMemCacheBytes
Cache Faults/sec - Number of faults, that occur
when a page sought in the file system cache is not found and must be retrieved
from elsewhere in memory (a soft fault) or from disk (a hard fault). The
file system cache is an area of physical memory that stores recently used
pages of data for applications. Cache activity is a reliable indicator
of most application I/O operations. This counter counts the number of
faults, without regard for the number of pages faulted in each operation.
OID: 1.3.6.1.4.1.232.19.2.4.7 - cpqOsMemCacheFaultsPerSec
Pool Nonpaged Bytes - 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. OID: 1.3.6.1.4.1.232.19.2.4.10 - cpqOsMemPoolNonpagedBytes
Cache Copy Reads/sec - Frequency of reads from
pages of the file system cache that involve a memory copy of the data
from the cache to the application's buffer. OID: 1.3.6.1.4.1.232.19.2.5.2.1.6 - cpqOsCacheCopyReadsPerSec
Cache Copy Read Hits % - Percentage of cache
copy read requests that hit the cache, that is, they did not require a
disk read to provide access to the page in the cache. A copy read is a
file read operation that is satisfied by a memory copy from a page in
the cache to the buffer of the application. OID: 1.3.6.1.4.1.232.19.2.5.2.1.3 - cpqOsCacheCopyReadHitsPercent
NetworkTCP
Active Connections - Number
of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state. Established Connections: Established Connections
is the number of times TCP connections which the current state is either
ESTABLISHED or CLOSE-WAIT. OID: 1.3.6.1.4.1.232.19.2.11.2.1.3 - cpqOsTcpActiveConnections
Established Connections - Number
of TCP connections for which the current state is either ESTABLISHED or
CLOSE-WAIT. OID: 1.3.6.1.4.1.232.19.2.11.2.1.4 - cpqOsTcpEstablishedConections
Segments/sec - Rate at
which TCP segments are sent or received using the TCP protocol. OID: 1.3.6.1.4.1.232.19.2.11.2.1.5 - cpqOsTcpSegmentsPerSec
Segments Retransmitted/sec - Rate
at which segments are retransmitted, that is, segments transmitted containing
one or more previously transmitted bytes. OID: 1.3.6.1.4.1.232.19.2.11.2.1.6 - cpqOsTcpRetransmittedSegmentsPerSec
Connection Failures - Number
of times TCP connections have made a direct transition to the CLOSED state
from the SYN-SENT state or the SYN-RCVD state, and the number of times
TCP connections have made a direct transition to the LISTEN state from
the SYN-RCVD state. OID: 1.3.6.1.4.1.232.19.2.11.2.1.7 - cpqOsTcpConnectionFailures
Controller
Total Bytes/sec - Rate
at which bytes are sent and received on the interface, including framing
characters. OID: 1.3.6.1.4.1.232.19.2.10.2.1.3 - cpqOsNetworkTotalBytesPerSec
Packets/sec - Rate at
which packets are sent and received on the network interface. OID: 1.3.6.1.4.1.232.19.2.10.2.1.4 - cpqOsNetworkPacketsPerSec
Output Queue Length - Length
of the output packet queue (in packets). If this length is longer than
2, delays are being experienced and the bottleneck should be found and
eliminated if possible. Since the requests are queued by the Network Driver
Interface Specification or NDIS in this implementation, this length will
always be 0. OID: 1.3.6.1.4.1.232.19.2.10.2.1.5 - cpqOsNetworkOutputQueueLength
Packet Outbound Errors - Number
of outbound packets that could not be transmitted because of errors. OID: 1.3.6.1.4.1.232.19.2.10.2.1.6 - cpqOsNetworkPktOutboundErrors
Packet Receive Errors - Number
of inbound packets that contained errors preventing them from being deliverable
to a higher-layer protocol. OID: 1.3.6.1.4.1.232.19.2.10.2.1.7 - cpqOsNetworkPktReceiveErrors
Current Bandwidth (Mbits/sec) - Estimate
of the current bandwidth of the interface in megabits per second. For
interfaces that do not vary in bandwidth or for those where no accurate
estimation can be made, this value is the nominal bandwidth. OID: 1.3.6.1.4.1.232.19.2.10.2.1.8 - cpqOsNetworkCurrentBandWidth
Bytes Sent/sec - Rate
at which bytes are sent on the interface, including framing characters. OID: 1.3.6.1.4.1.232.19.2.10.2.1.10 - cpqOsNetworkBytesSentPersec
Bytes Received/sec - Rate
at which bytes are received on the interface, including framing characters. OID: 1.3.6.1.4.1.232.19.2.10.2.1.11 - cpqOsNetworkBytesReceivedPersec
Packets Sent/sec - Rate
at which packets are sent on the network interface. OID: 1.3.6.1.4.1.232.19.2.10.2.1.12 - cpqOsNetworkPacketsSentPersecx1000
Packets Received/sec - Rate
at which packets are received on the network interface. OID: 1.3.6.1.4.1.232.19.2.10.2.1.13 - cpqOsNetworkPacketsReceivedPersecx1000
Physical Disks
Volume - Name of the
physical drive for which statistical information is gathered. OID: 1.3.6.1.4.1.232.19.2.7.2.1.2 - cpqOsPhysicalDiskInstance
Queue Length - Average
number of both read and write requests that were queued for the selected
disk during the sample interval. OID: 1.3.6.1.4.1.232.19.2.7.2.1.3 - cpqOsPhysicalDiskQueueLength
Disk Busy Time % - Percentage
of elapsed time that the selected disk-drive is servicing read or writes
requests. OID: 1.3.6.1.4.1.232.19.2.7.2.1.4 - cpqOsPhysicalDiskBusyTimePercent
ProcessesProcess - Name of the
task for which statistical information is gathered. OID: 1.3.6.1.4.1.232.19.2.12.2.1.2 - cpqOsProcessInstance
Threads - Number of threads
currently active in this process. An instruction is the basic unit of
execution in a processor, and a thread is the object that executes instructions.
Every running process has at least one thread. OID: 1.3.6.1.4.1.232.19.2.12.2.1.3 - cpqOsProcessThreadCount
Private Bytes - Current
number of bytes this process has allocated that cannot be shared with
other processes. OID: 1.3.6.1.4.1.232.19.2.12.2.1.4 - cpqOsProcessPrivateBytes
PageFile Bytes - Current
number of bytes this process has used in the paging files. Paging files
are used to store pages of memory used by the process that are not contained
in other files. All processes share paging files and a lack of space in
paging files can prevent other processes from allocating memory. OID: 1.3.6.1.4.1.232.19.2.12.2.1.5 - cpqOsProcessPageFileBytes
Working Set - Current
number of bytes in the working set of this process. The working set is
the set of memory pages touched recently by the threads in the process.
If free memory in the computer is above a threshold, pages are left in
the working set of a process even if they are not in use. When free memory
falls below a threshold, pages are trimmed from working sets. If they
are needed they will then be soft-faulted back into the working set before
they leave main memory. OID: 1.3.6.1.4.1.232.19.2.12.2.1.6 - cpqOsProcessWorkingSet
Page Faults/sec - Rate
at which the page faults occur in the executing threads within this process.
A page fault occurs when a thread refers to a virtual memory page that
is not in its working set in main memory. This will not cause the page
to be fetched from disk if it is on the standby list and already in main
memory, or if it is in use by another process with whom the page is shared. OID: 1.3.6.1.4.1.232.19.2.12.2.1.9 - cpqOsProcessPageFaultsPerSec
% CPU Time - Percentage
of elapsed time that all the threads of this process used the processor
to execute instructions. An instruction is the basic unit of execution
in a computer, a thread is the object that executes instructions, and
a process is the object created when a program is run. Code executed to
handle some hardware interrupts and trap conditions are included in this
count. On multi-processor machines, the maximum value of the counter is
100 % times the number of processors. OID: 1.3.6.1.4.1.232.19.2.12.2.1.7 - cpqOsProcessCpuTimePercent
% Privileged CPU Time - Percentage
of elapsed time that the threads of the process have spent executing code
in privileged mode. When a Windows NT system service is called, the service
will often run in privileged mode to gain access to system-private data.
Such data is protected from access by threads executing in user mode.
Calls to the system can be explicit or implicit, such as page faults or
interrupts. Unlike some early operating systems, Windows NT uses process
boundaries for subsystem protection in addition to the traditional protection
of user and privileged modes. These subsystem processes provide additional
protection. Therefore, some work done by Windows NT on behalf of your
application might be displayed in other subsystem processes in addition
to the privileged time in your process. OID: 1.3.6.1.4.1.232.19.2.12.2.1.8 - cpqOsProcessPrivilegedTimePercent
Processors
CPU - Name of the processor
for which statistical information is gathered. OID: 1.3.6.1.4.1.232.19.2.3.2.1.2 - cpqOsCpuInstance
Interrupts/sec - Average
number of hardware interrupts the processor is receiving and servicing
in each second, it does not include Deferred Procedure Calls or 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 ms, 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. OID: 1.3.6.1.4.1.232.19.2.3.2.1.3 - cpqOsCpuInterruptsPerSec
% User CPU Time - 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
OS components and allows direct access to hardware and all memory. The
OS 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. OID: 1.3.6.1.4.1.232.19.2.3.2.1.7 - cpqOsCpuUserTimePercent
% Privileged CPU Time - 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 CPU Time includes time servicing interrupts and
DPCs. A high rate of privileged time might be attributable to many interrupts
generated by a failing device. This counter displays the average busy
time as a percentage of the sample time. OID: 1.3.6.1.4.1.232.19.2.3.2.1.8 - cpqOsCpuPrivilegedTimePercent
% DPC Time - 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. OID: 1.3.6.1.4.1.232.19.2.3.2.1.10 - cpqOsCpuPercentDPCTime
% Interrupt Time - 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. OID: 1.3.6.1.4.1.232.19.2.3.2.1.11 - cpqOsCpuPercentInterruptTime
% CPU Time (Thresholds
Supported) - Percentage of time that the processor is executing a non-idle
thread. Designed as a primary indicator of processor activity, this counter
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, that 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%. OID: 1.3.6.1.4.1.232.19.2.3.2.1.4 - cpqOsCpuTimePercent OID: 1.3.6.1.4.1.232.19.2.3.2.1.5 - cpqOsWarCpuTimePercent OID: 1.3.6.1.4.1.232.19.2.3.2.1.6 - cpqOsCriCpuTimePercent
ServerSystem Health
System Up Time - 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. OID: 1.3.6.1.4.1.232.19.2.2.2 - cpqOsSystemUpTime
Total Threads - Number
of threads in the computer at the time of data collection. This count
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.
OID: 1.3.6.1.4.1.232.19.2.2.3 - cpqOsSystemThreads
Context Switches/sec - 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 pre-empted by a higher priority ready thread, or switches
between user mode and privileged (kernel) mode to use an executive or
subsystem service. The context switches/sec rate for all threads running
on all processors in the computer is measured in numbers of switches.
Context switch counters on the system and thread objects display the difference
between the values observed in the last two samples, divided by the duration
of the sample interval. OID: 1.3.6.1.4.1.232.19.2.2.4 - cpqOsSysContextSwitchesPersec
Processor Queue Length - Number
of threads in the processor queue. There is a single queue for processor
time even on computers with multiple processors. Unlike the disk counters,
this counter counts ready threads only, not threads that are running.
A sustained processor queue of greater than two threads generally indicates
processor congestion. This counter displays the last observed value only;
it is not an average. OID: 1.3.6.1.4.1.232.19.2.2.5 - cpqOsSysCpuQueueLength
Total Processes - Number
of processes in the computer at the time of data collection. This count
is an instantaneous count, not an average over the time interval. Each
process represents the running of a program. OID: 1.3.6.1.4.1.232.19.2.2.6 - cpqOsSysProcesses
% Registry Usage - Percentage
of the Total Registry Quota Allowed that is currently being used by the
system. This counter displays the current percentage value only; it is
not an average. OID: 1.3.6.1.4.1.232.19.2.2.7 - cpqOsSysRegistryInUsePercent
Security
Access Permission Errors - Number
of times opens on behalf of clients has failed with STATUS_ACCESS_DENIED.
This object can indicate random attempts to access files that are not
properly protected. OID: 1.3.6.1.4.1.232.19.2.9.4 - cpqOsServerAccessPermissionErrors
Access Granted Errors - Number
of times access to files opened successfully were denied. This object
can indicate attempts to access files without proper access authorization.
OID: 1.3.6.1.4.1.232.19.2.9.5 - cpqOsServerAccessGrantedErrors
Server Logon Errors - Number
of failed logon attempts to the server. This object can indicate whether
the password guessing programs are being used to violate the security
on the server. OID: 1.3.6.1.4.1.232.19.2.9.6 - cpqOsServerLogonErrors
Server Sessions Errored-Out - Number
of sessions that have been closed because of unexpected error conditions
or sessions that have reached the auto-disconnect timeout and have been
disconnected normally. OID: 1.3.6.1.4.1.232.19.2.9.7 - cpqOsServerSessionsErroredOut
Server Utilization
(Network Utilization)
Total Bytes/sec - Total bytes per second that aserver has sent to and received
from the network. This value provides an overall indication of how busy
the server is. OID: 1.3.6.1.4.1.232.19.2.9.2 - cpqOsServerTotalNetworkUtilizationBytesPerSec
Server Sessions - Number
of sessions currently active in the server. This object indicates current
server activity. OID: 1.3.6.1.4.1.232.19.2.9.3 - cpqOsServerSessions
Context Block Queue/sec - Rate
per second at which the work context blocks must be placed on the FSP
queue of the server to await server action. OID: 1.3.6.1.4.1.232.19.2.9.8 - cpqOsServerContextBlocksQueuePerSec
