We are in a fastcgi configuration and profiling application load times,
would like to know which server the request is being processed on.

Can you be more specific please ?

We are running a profile script which measures how long page load times
takes, how many queries run per page, etc.

One of the data parameters that I'd like to collect is which of the php-fpm
servers is actually running the php script.

$_SERVER["server_addr"] gives the web servers IP address.

One solution that I can think of is to have a unique configuration file
present on each application server that contains the IP address of that
server. This should work.

Someone else suggested using
http://php.net/manual/en/function.socket-getpeername.php but I don't have /
know how to get the socket resource to make the request.

Any thoughts / suggestions?

Thanks

if you're using nginx you can add:

fastcgi_param UPS_SERVER_ADDR $upstream_addr;

and get $_SERVER["UPS_SERVER_ADDR"].

That should work.

Thanks for your suggestion, but according to Nginx user group,

---
Variable $upstream_addr will be empty during creation request to
upstream.

variable $upstream_addr contains not a
single address, but a list of upstream addresses tried.
----

I'm going to test it out just to get an idea of what comes up...

Have you tried function: php_uname('n') to get the hostname of the
machine running the PHP script?

there's also posix_uname() too
