Linux monitoring tools nmon

Linux monitoring tools 
    nmon 
        nmon is a widely used in the Linux operating system monitoring and analysis tools, the recorded information nmon is more comprehensive, it can run in the system 
    to capture the usage of system resources in real-time process and can output results to a file, and generate a data file by nmon_analyzer FIG tool 
    graphical results. 

    nmon download and install 
        wget http://sourceforge.net/projects/nmon/files/nmon_linux_14i.tar.gz 
        tar gxvf nmon_linux_14i.tar.gz 

        mv nmon_x86_64_contos6 nmon 
        cp nmon / usr / bin / 

    nmon usage: 
        -f This is a must nmon parameter selection, and means must be placed first, is the output file; 
        with this argument, the file name is the default output nmon name: 
            hostname_data_time.nmon 

        -F <filename> this same parameter and -f, but the user may own definition file name; 

        -s data collection frequency, the frequency of which is stored data; 

        -c data collection frequency; 
        -t most resource-consuming process output data; 
        -h to see help;

    Command: 
        CD nmonData / 
        pwd 
        LL 
        nmon 
        nmon. 1 -f -F -C 10 demo.nmon -s -t 

    nmon_analyzer 
        effect nmon Analyzer is nmon analysis result of the data acquisition, nmon analyser required by Excel macro, WPS default 
    no macro , you need to download the plug
