Performance Monitor

Performance Monitor (known as System Monitor in Windows 9x, Windows 2000 and Windows XP) is a system monitoring program introduced in Windows NT 3.1. It monitors various activities on a computer such as CPU or memory usage. This type of application may be used to determine the cause of problems on a local or remote computer by measuring the performance of hardware, software services, and applications.[1][2]

In Windows 9x, System Monitor is not installed automatically during Windows setup, but could be installed manually using the Add/Remove Programs applet, located in the Control Panel.[3] It has few counters available and offers little in the way of customization. In contrast, the Windows NT Performance Monitor is available out-of-the-box and has over 350 performance measurement criteria (called "counters") available.[4] Performance Monitor can display information as a graph, a bar chart, or numeric values and can update information using a range of time intervals. The categories of information that can be monitored depends on which networking services are installed, but they always include file system, kernel, and memory manager. Other possible categories include Microsoft Network Client, Microsoft Network Server, and protocol categories.

In Windows 2000, the System Monitor of Windows 9x and the Performance Monitor of Windows NT 4 and earlier, as well as another program called Network Monitor, were merged into a Microsoft Management Console (MMC) plug-in called Performance, which consisted of two parts: "System Monitor" and "Performance Logs and Alerts".[5] The "System Monitor" naming was kept in Windows XP.[6] Some third-party publications referred to it as "Performance Monitor" however, even in Windows 2000[7] or XP contexts.[8]

The name displayed inside the MMC plug-in was changed back to "Performance Monitor" in Windows Vista, although it was also bundled with a Reliability Monitor and with a new performance summary feature called Resource Overview.[9][10] In Windows 7, the resource overview feature was split to a stand-alone Resource Monitor application, with the landing page for the Performance Monitor in Windows 7 containing a pointer to the (new) Resource Monitor; Windows 7 also moved the Reliability Monitor to the Action Center. A new feature added to the Performance Monitor in Windows Vista is Data Collector Set, which allows sets of accounting parameters to be easily manipulated as a group.[11]

Network Performance Monitoring Solution

Network Performance Monitor (NPM) is a solution in Operations Management Suite that monitors network performance between office sites, data centers, clouds and applications in near real-time. It helps a Network Administrator locate and troubleshoot bottlenecks like network delay, data loss and availability of any network link across on-premises networks, Microsoft Azure VNets, Amazon Web Services VPCs, hybrid networks, VPNs or even public internet links.

Optical performance monitoring

Optical performance monitoring (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). OPM involves assessing the quality of data channel by measuring its optical characteristics without directly looking at the transmitted sequence of bits. It is a potential mechanism to improve control of transmission and physical layer fault management in optical transmission systems.

In optical communications, typical roles for optical performance monitoring include ensuring correct switching in reconfigurable optical add-drop multiplexers, setting levels for dynamic equalization of the gain of optical amplifiers, and providing system alarms and error warning for lost or out of specification optical channels.

The optical component used for this purpose in DWDM networks is known as optical performance monitor (OPM) or optical channel monitor (OCM), which measures channel power, wavelength, and optical signal-to-noise ratio (OSNR) for each channel.

Perf (Linux)

perf (sometimes called perf_events or perf tools, originally Performance Counters for Linux, PCL) is a performance analyzing tool in Linux, available from Linux kernel version 2.6.31. Userspace controlling utility, named perf, is accessed from the command line and provides a number of subcommands; it is capable of statistical profiling of the entire system (both kernel and userland code).

It supports hardware performance counters, tracepoints, software performance counters (e.g. hrtimer), and dynamic probes (for example, kprobes or uprobes). In 2012, two IBM engineers recognized perf (along with OProfile) as one of the two most commonly used performance counter profiling tools on Linux.

Photovoltaic system

A photovoltaic system, also PV system or solar power system, is a power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery solution, as prices for storage devices are expected to decline. Strictly speaking, a solar array only encompasses the ensemble of solar panels, the visible part of the PV system, and does not include all the other hardware, often summarized as balance of system (BOS). Moreover, PV systems convert light directly into electricity and shouldn't be confused with other technologies, such as concentrated solar power or solar thermal, used for heating and cooling.

PV systems range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts. Nowadays, most PV systems are grid-connected, while off-grid or stand-alone systems only account for a small portion of the market.

Operating silently and without any moving parts or environmental emissions, PV systems have developed from being niche market applications into a mature technology used for mainstream electricity generation. A rooftop system recoups the invested energy for its manufacturing and installation within 0.7 to 2 years and produces about 95 percent of net clean renewable energy over a 30-year service lifetime.Due to the exponential growth of photovoltaics, prices for PV systems have rapidly declined in since their introduction. However, they vary by market and the size of the system. In 2014, prices for residential 5-kilowatt systems in the United States were around $3.29 per watt, while in the highly penetrated German market, prices for rooftop systems of up to 100 kW declined to €1.24 per watt. Nowadays, solar PV modules account for less than half of the system's overall cost, leaving the rest to the remaining BOS-components and to soft costs, which include customer acquisition, permitting, inspection and interconnection, installation labor and financing costs.

ReadyBoost (codenamed EMD) is a disk caching software component developed by Microsoft for Windows Vista and included in later versions of the Windows operating system. ReadyBoost enables NAND memory mass storage devices, including CompactFlash, SD cards, and USB flash drives, to be used as a write cache between a hard drive and random access memory in an effort to increase computing performance. ReadyBoost relies on the SuperFetch technology and, like SuperFetch, adjusts its cache based on user activity. Other features, including ReadyDrive, are implemented in a manner similar to ReadyBoost.

Resource Measurement Facility

Resource Measurement Facility (RMF) is a performance monitor for the z/OS Operating System. It also collects data for long-term performance analysis and capacity planning. The product consists of the following components:

Monitor I Data Gatherer which collects data in adjustable intervals from one minute to one hour. The data is written to SMF data sets. RMF Monitor I uses the SMF data record types 70 to 78. In addition a dataspace can be created for the Monitor I data gather in which the most recent RMF SMF data records are buffered so that the RMF Postprocessor can access and process them immediately.

Monitor III Data Gatherer collects data for short-term and immediate data analysis. The data is collected in intervals ranging from 10 seconds to 10 minutes. The data is written to RMF Monitor III VSAM data sets and internally recorded in a wraparound buffer. The data gatherer also collects some special data for long-term data analysis and records them in RMF SMF records too.

Monitor II is the original snap shot monitor of RMF. This function also records information in RMF SMF record type 79 and provides interfaces for other reporting functions like SDSF. Over the years this function became less important and is today mostly used as a data provider for other reporting components.

RMF Postprocessor is the reporting tool for RMF SMF records of type 70 to 78. It generates a big number of tabular and textual reports for long-term data analysis which provide a lot of detail of z/OS and System z performance.

RMF Spreadsheet Reporter is an extension of the RMF Postprocessor and displays selected data in spreadsheet applications on a workstation.

RMF Monitor III Reporter is the display tool of RMF Monitor III data. The function is written in ISPF and runs under a TSO session on z/OS. The reporter allows to move forward and backward in time and uses RMF Monitor III in-storage buffer and data sets to access the collected data.

RMF PM and the RMF Webportal are workstation enhancements for RMF Monitor III. They allow multiple z/OS systems to be displayed in the same data view. RMF PM is a Windows-based application and the Webportal allows the user to display screens using a frames-capable web browser.RMF is significantly enhanced with every release of the z/OS Operating System – that is approximately once a year – with other enhancements occurring in support of new hardware, such as new processor models.

System monitor

A system monitor is a hardware or software component used to monitor system resources and performance in a computer system.A hardware monitor is common component of modern motherboards, which can either come as a separate chip, often interfaced through I²C or SMBus, or as part of a Super I/O solution, often interfaced through Low Pin Count (LPC). These devices make it possible to monitor temperature in the chassis, voltage supplied to the motherboard by the power supply unit and the speed of the computer fans that are connected directly to one of the fan headers on the motherboard. Many of these hardware monitors also have fan controlling capabilities. System monitoring software like SpeedFan on Windows, lm_sensors on GNU/Linux, envstat on NetBSD, and sysctl hw.sensors on OpenBSD and DragonFly can interface with these chips to relay this environmental sensor information to the user.
