NAME

       wulfweb - A script to create an html table of cluster node statistics

SYNOPSIS

       wulfweb  [-d  delay]  [-f  wulfhosts]  [-i  include]  [-p  path] [-t type] [-h] [-v level]
       filename

WULFWEB OPTIONS

         filename (required) is the name of the web page created (e.g. mycluster.html)
         -d delay sets the delay used for both wulflogger and page updates
         -f wulfhosts to specify a particular wulfhosts file
         -i include file (which must contain html intended to go  after  <html>  and  before  the
       table in the created web page).
         -t type to control wulflogger "type" of display.
         -h displays help/usage
         -v level controls verbosity and debugging output

DESCRIPTION

       wulfweb is a script that creates a web page containing an optional inclusion (described in
       detail below) followed by an html table formatted to contain automatically updated cluster
       statistics collected from xmlsysd's running on the cluster nodes by wulflogger.  Note that
       wulflogger is therefore required by the wulfweb program.

       A typical invocation might be:

       $ wulfweb -f /usr/share/wulfweb/wulfhosts -d 60 -t 1 \
            -i myheader.html mycluster.html &

       to create a page with the header myheader.html in front of the "load averages" table  that
       auto-refreshes  every  60  seconds.   The  cluster is described in the wulfhosts file (see
       wulfstat(1) or wulflogger(1) for details). Run in the background, wulfweb will  keep  this
       page current indefinitely.

INCLUDED FILE

       The  included file must contain valid html for material that you might wish to precede the
       table.  It can be empty (or no include file may be given on the  command  line)  in  which
       case  the raw table and the <meta> tag that causes automatic refresh are the sole contents
       of the output file.

       The included header file can be as fancy as you like, but I'd strongly urge  that  if  you
       want  to  embed  the tables in a complex document you consider using php and including the
       table in a php-generated page, as otherwise I think  you'll  find  this  simple  inclusion
       mechanism limiting.

       Be  warned!   Check  the resulting documents produced carefully for errors!  The most that
       wulfweb can do is produce the table (hopefully correctly).  Obviously it cannot be  blamed
       for bad html in any inclusion.

       The following is an example of a reasonable inclusion that should work:

       <html>
        <head>
          <title>MyCluster Stats</title>
        </head>

        <body>

        <h2>MyCluster Load Average</h2>

        <hr>

DISPLAY TYPES

       The following display types are supported by wulflogger:

         0 - a "vmstat-like" display of stats from all cluster hosts.  Probably
             the most useful single display.
         1 - load average only
         2 - memory utilization (similar to running "free" on each host)
         3 - network rates
         4 - time displays system clocks, uptime, cpu type and clock
         5 - pids interface for monitoring running distributed tasks.
         6 - pids interface for monitoring running distributed tasks with
             full command line displayed.

       The  pids  interface (with or without the full command line displayed) is a bit quirky. It
       will generally ignore root-owned tasks, for example, presuming that the tool  is  intended
       to  monitor  userspace applications.  There exist wulfhosts controls for these properties;
       eventually they will likely be controllable at the command line of this tool as well.
