CFML to check my Server Status..

Question

Hello,
I have 3 Name servers and 2 Web Servers and 1 SQL server all
at seperate IP #'s. I have a admin toolset for several websites and
I wanted to add a Status checker to alert the users if any given
server was offline before they tried to admin their sites (Or
disable functions that rely on file parity, etc.) At first I tried
to find CFML to "ping" the servers but no luck. Then i thought I
would skip the Nameservers check and just check the webservers. So
I put a file on each server that I could cfinclude. Then i
remembered I can't use an IP address with cfinclude. So I used an
IFRAME to include the file from the IP/dir I wanted. I wrapped this
in a cftry/cfcatch block, but of course the failure is page not
found when the server is offline and is not a direct cfinclude. So
if I cfinclude a page with a IFRAME call to an IP addressed page
and the server is down I get a broken IFRAME. Is there any CGI var
or CFML readable info in a 404 return I can check for to report
failure, rather than missing page error? OR, is there an easier
more intelligent way to do this? See my current code below:

That link was great, it solved most of the problem. I
obviously run a query on the SQL Server to test it, and the CFHTTP
routine worked great for the webservers. Now is their any way to
ping a DNS server? From cf I mean? Below is the trimmed code I
garnered from the EasyCFM link you gave;
