	The current system is too many monitoring tools, there are a lot of mature open source, but also my own writing tool, but it is estimated that very few people know that the most traditional cgi program can also achieve the effect of a simple web page monitoring. First modify the apache configuration file support New m.cgi in / var / www cgi-bin / directory / Code is as follows: #! / Bin / bash echo "Content-type: text / html" echo "" echo "<html> <head> <title> Host Monitoring page" echo "</ title> </ head> <body>" echo "<h1> hosts $ (hostname) - $ (ifconfig eth0 \| grep 'inet addr' \| awk -F": " '{print $ 2}' \| awk -F" " '{print $ 1}') </ h1> " echo "" echo "<h1> <p> <font color =" # FF0000 "size = 5 face =" Microsoft elegant black "> Memory Usage </ font> </ h1>" echo "<pre> $ (free -m) </ pre>" echo "<h1> <font color =" # FF0000 "size = 5 face =" Microsoft elegant black "> Disk Usage </ font> </ h1>" echo "<pre> $ (df -h) </ pre>" echo "<h1> <font color =" # FF0000 "size = 5 face =" Microsoft elegant black "> port </ font> </ h1>" echo "<pre> $ (netstat -tunlp) </ pre>" echo "<center> <font color =" # FF0000 "size = 3 face =" Microsoft elegant black "> the current system time $ (date +"% Y-% m-% d% H:% M:% S ") </ font> </ center> " echo "</ body> </ html>" </td> <td background="../../c6.jpg"> </td> <td background="../../c4.jpg"> </td> <td background="../../c6.jpg"> </td> </tr> <tr> <td height="20" background="../../c4.jpg"> </td> <td align="center" valign="middle"> </td> <td background="../../c6.jpg"> </td> <td background="../../c4.jpg"> </td> <td background="../../c6.jpg"> </td> </tr> <tr> <td height="20" background="../../c4.jpg"> </td> <td align="center" valign="middle"> </td> <td background="../../c6.jpg"> </td> <td background="../../c4.jpg"> </td> <td background="../../c6.jpg"> </td> </tr> <tr> <td height="20" background="../../c4.jpg"> </td> <td align="center" valign="middle"> </td> <td background="../../c6.jpg"> </td> <td background="../../c4.jpg"> </td> <td background="../../c6.jpg"> </td> </tr> <tr> <td height="20" background="../../c4.jpg"> </td> <td align="left" valign="middle">More:</td> <td background="../../c6.jpg"> </td> <td background="../../c4.jpg"> </td> <td background="../../c6.jpg"> </td> </tr> <tr> <td height="20" background="../../c4.jpg"> </td> <td align="center" valign="middle"><div align="left"> <a href='http://www.newfreesoft.com/database/exp_00091_exporting_questionable_statistics_processing_method_5572/' target='_blank' border=0> -
