Introduction
The task for this week's assignment is to discuss specific common areas of concern in reporting hard drive, network, and memory issues, explaining what to look for in these areas.
Overview
Regular performance monitoring ensures that administrators always have up-to-date information about how their servers are operating. When administrators have performance data for their systems that cover several activities and loads, they can define a range of measurements that represent normal performance levels under typical operating conditions for each server. This baseline provides a reference point that makes it easier to spot problems when, or before they occur. In addition, when troubleshooting system problems, performance data gives information about the behavior of the various system resources at the time the problem occurs.
Hard Drive Monitoring
There are many factors that need to be monitored to determine the performance of a hard drive system. For the purpose of this paper, I will be focusing on two areas that I feel are important. They are disk space and disk efficiency.
Disk space is important to monitor because some applications may fail to run if they can't allocate the required space needed to work. Also, low disk space can limit the ability of the paging file to grow as needed, which in turn affects the system's virtual memory. If the paging file can't grow then virtual memory is severely limited which could slow down or crash a system.
Using the built-in monitoring utility Performance Monitor (Perfmon.msc), under the category Add Counters/Performance Object/LogicalDisk, there are two counters that can be used to monitor disk space. They are "% Free Space" and "Free Megabytes". The % Free Space counter displays the percentage of total usable free space on the selected logical drive or drives. This is a much better indication of free space than right clicking the drive and viewing its properties. The Free Megabytes counter basically provides the same type of information, but in a different format. It displays the available free space in megabytes instead of percentages. If after running these counters it's determined that space is running low, the administrator should try running "Disk Cleanup" from within Performance Monitor, compress the hard drive if feasible, or move some files to another disk drive.
Monitoring disk efficiency is a little more complicated than monitoring free space, but is necessary to ensure that the disk drives are running at peak performance. There are a few steps that should be taken prior to monitoring disk efficiency.
Performance measures, or quality indicators, are metrics based on objective data that allow one to assess whether a system is achieving an intended goal. A requisite of metrics will need to be established to maintain ongoing efforts to show variable

Operations are all the processes in transforming inputs into desired outputs. These processes must be efficiently and effectively coordinated by managers and eventually they must accomplish specific organizational goals. All operations, despite how well managed they are, are capable of improvement. In order for the operations to be improved however, weaknesses should be identified first. Therefore operations need some kind of performance measurement as a prerequisite for improvement.
Its important to measure the business results though is difficult and sometimes cost fully. The reason is that it assists the early identification of the problem and finally positive and negative trends of the business activities could be
As per Harvard Mentor Review, measuring performance of companies is important for the following reasons:
So people see there is a lot of data out there. The storage capabilities of hard drives have increased massively over the years, but the access speeds, the rate at which data can be read from drives have not kept up. One typical drive from 1990 could store 1370 MB of data and had a transfer speed of 4.4 MB/s [2], (1370 MB)/(4.4 MB/s) = 311 s = 5.1 minutes, so the time for reading all the data from a full drive was around 5 minutes at that time. After 20 years, one terabyte drives are the norm, but the transfer speed is around 100 MB/s, so it takes more than two and a half hours to read all the data off the disk.
This white paper identifies some of the considerations and techniques which can significantly improve the performance of the systems handling large amounts of data.
In the middle of the 70s’ century, the Personal Computer (PC) industry can be divided into two main groups of players: the first one owned more than 50% of the market share and was called “clone markets” because its composed by many local brand that produce PC assembling components by themselves, and their computers was not too much different from the others made by big corporations. The second one was composed by the main companies producing computer, for instance IBM, Dell, HP, Gateway, in a standardize way. In this context Jobs and Wozniak set-up Apple, a new company in the PC market, starting from their own capabilities and resources in the Jobs’ garage,
Analytical study of logs support accurate interpretation of the current state, prediction of upcoming state, and suggest certain reactive measures in a scenario. With such a diverse and rich lot of information, statistical analysis will easily monitor the system performance and take proactive measures to improve it without human intervention. A screenshot in Figure-1 showing 195 log files on a Windows system can give an estimate how diverse and rich information does they contain.
When implementing a new performance management system in an organization there are both advantages and disadvantages that need to be taken into consideration by the design team. However, one of the best ways to know if a performance management system is effective is by implementing the system within the organization and then continuously monitor and reevaluate if the system is still relevant to the organizational
The more operation and task you do with your Pc the more your hard drive becomes fragmented with many files that are broken and scattered in different locations. This takes windows more time to access information from the different locations slowing operations and execution of programs. This is way defragmenting your hard drive is necessary to assemble broken files and make it easier to find.
Active monitoring can distinguish execution and network issues from various Internet focuses. This is an outside methodology and accordingly is intended to recreate an end-client experience. Active monitoring arrangements empower issue ID it can figure out whether a site or application is moderate or encountering downtime inside of minutes of the event. Moreover, by observing from an outside viewpoint, active monitoring empowers
In all of the research and documentation used to create this paper Performance Support System (PSS) and Electronic Performance Support System (EPSS) are used synonymously. The term Electronic Performance Support System (EPSS) will be used in this paper.
Paging is one of the memory-management schemes by which a computer can store and retrieve data from secondary storage for use in main memory. Paging is used for faster access to data. The paging memory-management scheme works by having the operating system retrieve data from the secondary storage in same-size blocks called pages. Paging writes data to secondary storage from main memory and also reads data from secondary storage to bring into main memory. The main advantage of paging over memory segmentation is that is allows the physical address space of a process to be noncontiguous. Before paging was implemented, systems had to fit whole programs into storage, contiguously, which would cause various storage problems and fragmentation inside the operating system (Belzer, Holzman, & Kent, 1981). Paging is a very important part of virtual memory impl...
Choosing which motherboard to use is important. It also is closely related to what processor is chosen. Because of cost saving factors, the AMD Athlon processor is the best choice. Therefore we can only provide a motherboard compatible with the AMD AthlonXP 1900. For our client, we decided on the motherboard Aopen K77-333. This motherboard is an excellent choice for our client because:
