What Is the Complete System Performance Monitor?The Complete System Performance Monitor (CSPM), written by Don Dupuis ofCompaq Computer Corporation, is a graphical tool that monitors a L buy fioricet online nux®system's CPU, memory, storage, network, and IRQ utilization. CSPM gathers allthe data automatically and then generates histogram displays of system usage.------------------------------------ buy fioricet online ----------------------------------------3. RequirementsCSPM V1.0 and later require the following: * Red Hat Linux 7.2 or later, Mandrake 8.2 or later, or any Linux kernel that has Stephen Tw buy fioricet online edie's sar or sysstat patch applied (such as 2.4.20). * The Trolltech Qt 3.0 or later C++ application development environment, which is available for download from Trolltech for free. - buy fioricet online ---------------------------------------------------------------------------4. Installing CSPM and its requirementsThis section describes how to acquire the Qt application developmentenvironment buy fioricet online nd install CSPM.-----------------------------------------------------------------------------4.1. Installing Qt 3.0 or laterQt 3.0 or later must be installed on the system before you install CSP buy fioricet online .Follow these steps to acquire and configure Qt: 1. Download the Qt X/11 Free Edition from [www.trolltech.com] http:// www.trolltech.com for the latest version of Qt. 2. Follow Trolltech's buy fioricet online instructions for installing Qt. 3. Run ./configure with the -thread switch to the configure program so that Qt is installed to run in multithreaded mode. # ./configure -thread buy fioricet online 4. Be sure to export the variables QTDIR and LD_LIBRARY_PATH, as described in the Qt installation instructions that are downloaded with the sof buy fioricet online ware. -----------------------------------------------------------------------------4.2. Installing CSPMThe following sections describe how to download and install CSPM. These stepsmust be run buy fioricet online y the root user. The installation process creates a directorycalled spm and places all the files in that directory.-----------------------------------------------------------------------------4. buy fioricet online .1. Installing from rpmFollow these steps to install CSPM from the rpm file: 1. Download the CSPM rpm file from SourceForge at [http://sourceforge.net/ projects.cspm] http://sourceforge.net/p buy fioricet online ojects/cspm. The program name for CSPM is spm2. 2. Install the software: # rpm -ihv --nodeps spm2-1.0-1.586.rpm The rpm creates the binary call buy fioricet online pm2 in the current directory. -----------------------------------------------------------------------------4.2.2. Installing from tarFollow these steps to install CSPM from the tar file: 1. Do buy fioricet online nload the CSPM tar file from SourceForge at [http://sourceforge.net/ projects.cspm] http://sourceforge.net/projects/cspm. The program name for CSPM is spm2. 2. Untar the spm2.tar.gz fil buy fioricet online : # tar xvzf spm2.tar.gz 3. Compile CSPM: # make all The make com buy fioricet online and creates the binary call spm2 in the current directory. -----------------------------------------------------------------------------4.3. Starting the CSPM monitorThe spm2 program should be buy fioricet online run by a user other than root so that any changesto the default preference settings can be changed.Enter the following command from the directory where CSPM is installed:# ./spm2 buy fioricet online If a segmentation fault occurs when spm2 is starting up, make sure that youhave set the QTDIR and LD_LIBRARY_PATH variables, as described in t buy fioricet online e Qtinstallation instructions that are downloaded with the software.-----------------------------------------------------------------------------5. Modifying CSPM defaultsBy default, the number buy fioricet online f "range bars" along the y-coordinate of eachhistogram is five. When there is no activity for a particular device, CSPMprovides default values of 0, 0.2, 0.4, 0.6, and 0.8. Once activity begins buy fioricet online nthe device, CSPM sets the five values in equal increments from 0 to the peakdata value collected in each collection interval. Sometimes the grid linesfall directly on the range bar numbers, mak buy fioricet online ng the numbers hard to read. Youcan either adjust the color of the grid lines, adjust the collectioninterval, or try to ignore the grid lines.You can modify the default grid, sizing, and monitor buy fioricet online ng settings for each ofthe views from the Preferences pulldown. From the Preferences pulldown, youcan select System, Tests, CPU, Memory, Network, Storage or IRQs. Once youselect a particular ite buy fioricet online , you can view the Grid, Monitoring, or Sizing tab(if applicable) for that item.From the Grid tab you can change such things as: * the color of the grid lines * the distance (or time), in s buy fioricet online conds, between intervals when data is collected (horizontal lines appear at each interval) * the color of the various data bars (such as read, write, user, nice, and "sys") * the n buy fioricet online mber of horizontal range bars (default is 5) * the size of the histogram titles From the Monitor tab you can change things such as: * the height and width of the display boxes (in pixels) buy fioricet online * the colors of the display boxes * the type of data to be monitored (IOs, data, reads and writes, sectors and blocks) From the Sizing tab you can change the minimum height and widt buy fioricet online of thedisplay boxes (in pixels).-----------------------------------------------------------------------------6. How CSPM displays dataCSPM displays histograms that provide information about sys buy fioricet online em usage. Theprogram has 8 display tabs for the different types of system information CSPMcollects. These tabs are: * System Overview * IRQs * CPU Utilization * Memory * Network buy fioricet online * Storage * Tests * Test Summary The key at the bottom of the histogram tables on each of the tabs tells howto interpret the various colors representing data in the tables.Use the buy fioricet online orizontal and vertical scroll bars to view any histograms that donot fit on the initial screen.-----------------------------------------------------------------------------6.1. System Overview t buy fioricet online bWhen CSPM starts up, the System Overview screen is displayed. The histogramson the System Overview screen show data for the total system, including CPU,memory, network, and storage usage. The f buy fioricet online llowing screenshot shows a sampleview of a System Overview screen.[sysover]Below each histogram is a key that describes the data that is represented.For example, in the CPU total histogram, the buy fioricet online ed line represents user CPUusage, the green line represents commands run with a modified schedulingpriority (nice), and the blue line represents system CPU usage.-------------------------------- buy fioricet online --------------------------------------------6.2. IRQs tabWhen you click the IRQs tab, a histogram opens for each IRQ line that runs toan ISA slot on the system. The following screenshot shows a buy fioricet online ample view ofthe IRQs screen.Note Note With Qt 3.0, the horizontal scroll bars on the Irqs tab does not work proper buy fioricet online y. This problem does not occur with Qt 3.1. [irqs]The large blue number to the left of the histogram is the number of the IRQ.The red line on each histogram represents the n buy fioricet online mber of IRQs per secondutilitized by the device connected to the IRQ's ISA slot.-----------------------------------------------------------------------------6.3. CPU Utilization tabWhen you clic buy fioricet online the CPU Utilization tab, histograms open for each CPU on thesystem, as shown in the following screenshot:[cpu]The histograms show information about user (red), system (blue), and nicepriority ( buy fioricet online reen) command utilization.-----------------------------------------------------------------------------6.4. Memory tabThe Memory tab is still under development. In a future release of CSPM, the Memory tab will graphically show how much memory processes use, from most toleast.-----------------------------------------------------------------------------6.5. Network tabWhen you click the Network tab, histograms that show the amount of traffic onthe system's loopback device and each network device are displayed, as shownin the following screenshot.[network]Sends are shown in red and receives are shown in blue.-----------------------------------------------------------------------------6.6. Storage tabWhen you click the Storage tab, a collection of histograms opens that showdata for controllers, disks, and partitions. The key at the bottom of thehistograms tells which color of histogram box corresponds to which type ofdevice.[storage]The screenshot displays purple for controllers, green for disks, and orangefor partitions. The red lines represent reads from the devices and the bluelines represent writes to the devices.To see information about a partition (such as file system name, spa
