If you have a website and want to know when it
goes down, here's how to do it:
Requirements:
Hosting service account that includes NT/IIS, ASP support.
You must have a directory that has write permission for scripts (IIS user) -
Some services provide you with one, others allow you to set permissions, and
still others require you contact support to have them set permissions.
Limitations:
An ASP page must be accessed from your site after the server restarts for the
log entry to occur.
The date & time logged will be that of the first such access, not the actual
restart time.
Depending upon the traffic to your site, the server could go down and back up
without it being logged before it goes down and up again.
The logging is accomplished by the special
global.asa file. If your site already has a global.asa file, you will need to
edit it, inserting the code between the SUB and END SUB sections in existing
Application_OnStart section of your file. If your site doesn't already have a
global.asa file, you can create a file with just the code below, and add it to
your root virtual web.
<SCRIPT LANGUAGE="VBScript" RUNAT="Server">
Sub Application_OnStart
whichfile=server.mappath("/cgi-bin/server.txt")
On Error Resume Next
Set fs = CreateObject("Scripting.FileSystemObject")
Set thisfile = fs.OpenTextFile(whichfile, 8,0)
if err then
Set thisfile = fs.OpenTextFile(whichfile, 8,1)
thisfile.writeline "Date & Time of Server Restart"
end if
logwrite= formatdatetime(now(),0)
thisfile.writeline logwrite
thisfile.close
set thisfile = nothing
set fs = nothing
End Sub
</SCRIPT>
To read your log file, simply FTP to your
virtual server's cgi-bin directory, and grab server.txt.
Or, you can create a web page (log.asp)
to display the log. The basic code to do this:
To test the script on your server, create a
test.asp file without the Sub and EndSub, load and run it. If the server.txt
file doesn't appear in your /cgi-bin directory, you can remove the OnErrorResume
next, create an empty server.txt file in the cgi-bin directory, and run
the .asp file to see what error you get (probably permissions...). If your host
gives write access to a different directory, you can simply change the line that
specifies /cgi-bin/server.txt to the desired path.
