                                HTTPdMon.c

This utility displays information about a WASD HTTPd server.  The information 
is derived from JPI data about the process, and read from a permanent system
global section in(to) which the server keeps the accounting and writes the
request data.

The /ALERT and /ALERT=ALL parameters ring the bell every time a new request is
reported (the connect count increases).  The /ALERT=HOST rings the bell every
time the host name in the request changes.  With /ALERT=PATH[=<integer>] when a
path matched by the mapping rule "SET /path* ALERT" is detected by the server
the bell is rung <integer> times (default is 10). The /LOOKUP qualifier
(default) attempts to resolve a dotted-decimal host address in the request (if
the server's [DNSlookup] configuration directive is disabled).  This operation
can introduce some latency as name resolution occurs.  A trailing "#" indicates
this is an address that has been resolved this way.  If it cannot be resolved a
"?" is appended to the numeric address.

The "(n servers)" field keeps track of multiple servers on a node or cluster. 
When there is a change in the number the previous value is displayed in
parentheses after the current and the terminal bell is rung (this can be
suppressed with "/ALERT=NOSERVERS").  Of course servers coming and going are
only detected if it happens at a frequency greater than the current display
interval.


QUALIFIERS
----------
/ALERT[=ALL|HOST|PATH[=<integer>]|[NO]SERVERS]
                        ring bell for all accesses or
                        just a change in host and/or
                        suppress bell if server count changes
/ALL=string             set the server-group name (up to 8 characters)
/DBUG                   turns on all "if (Debug)" statements
/DEMO                   demonstration mode (matches that of the HTTPd)
/ENV=<integer>          refer to this WASD environment (2..15)
/[NO]GENERAL            display general HTTP serving information
/HELP                   display brief usage information
/IDENTIFICATION=        the specific instance (server) process PID
/INTERVAL=              number of seconds between display refresh
/[NO]LOOKUP             resolve dotted-decimal host addresses to names
/PLUCK                  place selected statistics into global DCL symbols
/PORT=                  the IP port number of the server to monitor
/[NO]PROCESS            display HTTPd process information
/[NO]PROXY              display proxy serving information
/[NO]REQUEST            display request information
/[NO]STATUS             display instance information
/REFRESH=               synonym for /INTERVAL


REQUIRED PRIVILEGES
-------------------
WORLD      for access to the server process' JPI data

See [SRC.HTTPD]CONTROL.C for other information.  Uses the VMS Distributed Lock
Manager to keep track of how many servers are currently executing on the
node/cluster.  NL locks indicate interest (used by this utility), CR locks
indicate a server waiting for a group directive.  This function enqueues a
single NL lock, then periodically get all the locks associated with that
resource and counts up the number of CR locks - giving the number of servers!
If the number of servers varies then (by default) sound the bell!!

Get the IP name using asynchronous address-to-name lookup.  Despite the implied
IPv6 functionality TCP/IP Services lookup only supports IPv4 (sigh, one day
perhaps).

Returns /%X00000014 %SYSTEM-F-BADPARAM, bad parameter value/ when fed an IPv6
address string.

There will always be a delay in the lookup because this function is 
called during AST delivery, so buffer the IP addresses and host names.  Returns
a pointer to the host name, to '?' during lookup, or '!' if not resolvable.
