like.SizefmtFile size display mode. The default format is byte ("bytes"). You can change the format to kilobytes ("abbrev ")TimefmtTime Display Mode, the most flexible configuration of attributes. Example: display the size of a non-existing file Display file size in kilobytes Syntax: Display time in a specific time format Displays the day of the week, month, and time zone. XSSI XSSI (Exte

output of an external program to the page. The input of a CGI program or a general application can be inserted, depending on whether the parameter is cmd or cgi. Syntax: Parameters: CmdRegular applicationsCgiCGI script program Example: Note: As shown in the preceding example, this command is quite convenient, but there are also security problems. Method prohibited: Apache: Delete the "Options except des ExecCGI" line of code in access. conf; To disable the # exec command in IIS, modify the

of showing CPU load than the average load, and the data does not contain the process of waiting for IO. If this value is greater than the number of machine CPU cores, then the CPU resources of the machine are saturated (CPU bottlenecks are present). B: The number of processes waiting for IO.

the Info.txt document under the current directory virtual Specifies the location relative to the server document root directory, as/hoyi/info.txt Note: The file name must have an extension. Example: #exec Demonstration Action: Inserts the output of an external program into the page. You can insert a CGI program or an input to a regular application, depending on the parameter is cmd or CGI. Grammar: Parameters: CMD general application CGI CGI script program Example: Note: As you can see from the

ways can achieve the same goal) 9, Exception object Exception implicit objects can be accessed directly in a Web page that handles exceptions. -----------------------------------Supplementary Part-------------------------------- ①out-javax.servlet.jsp.jspwriterThe Out object is used to output the results to the Web page. Method:1. void clear ();Clears the contents of the output buffer, but does not output to the client. 2. void Clearbuffer ();Clears the contents of the output buffer and output

access_log.cgi. Note: As you can see from the example above, this instruction is quite handy, but there are also security issues. Prohibited method: Apache, delete the "options Includes execcgi" code in access.conf; In IIS, to disable the #exec command, you can modify the SSIExecDisable metabase; #config Role: Specifies the format for error messages, dates, and file sizes returned to the client browser.

activities. It is characterized by reporting disk activity statistics and also reporting CPU usage. Like Vmstat, Iostat also has a weakness that it cannot analyze a process in depth and only analyze the overall situation of the system.The syntax for Iostat is as follows:Iostat [-C |-d] [-K] [-t] [-v] [x [Device]] [interval [count]]Where-C to report CPU usage;-D to report disk usage;-K means to display data by kilobytes byte per second;-T for print re

clear that the NC process is consuming CPU 1 100% CPU. Because the process of consuming CPU in the test system is relatively small, at a glance, Pidstat in the production system should be able to output more CPU-consuming processes. 6. IOSTAT-ZX 1 Learn about the load and performance tools for block devices (block device, disk).
