Hi, we have cluster of 25 nodes and we wanted to see overall cluster utilization report.We are getting individual nodes utilization.But we want combined utilization. We to get that. os : rhel 5.2

I'm not sure if bbcombotests can really do this, but it might be a good way to start, at least for threshold generation.
http://www.hswn.dk/hobbit/help/manpages/man5/bbcombotest.cfg.5.html
If you're looking for rrd-type graphs, you could try automating or defining links to the metrics report cgi at http://www.hswn.dk/hobbit/help/manpages/man1/hobbit-hostgraphs.cgi.1.html
If all else fails, create a script that reads your RRDs for the individual hosts directly and composes something custom, then have it run as an external script on your server, feeding a new custom test back into hobbit with the bb command.

Do you mean one graph showing the individual (e.g. load average) utilisation for 25 servers? It seems (at least for me on 4.2.3) that the metrics report only works up to 2 servers, but the method from before the metrics report, adding more host names to the normal trends graphs, works fine at least up to 8 servers.
So, view the "cpu" page for a server, click on the graph, you should be at a URL such as:
http://xymon.mydomain.com/xymon- cgi/hobbitgraph.sh?host=server1.mydomain.com&service=la&graph_width=576&graph_height=120&disp=zcs- mbs1.zmb.com&nostale&action=menu
Now, edit the URL in your browser, to something like this:
http://xymon.mydomain.com/xymon- cgi/hobbitgraph.sh?host=server1.mydomain.com,server2.mydomain.com&service=la&graph_width=576&graph_height=120&disp=zcs- mbs1.zmb.com&nostale&action=menu
Keep adding host names as used in Xymon to the host= parameter, separated by commas.
You may want to keep this URL, by bookmark, or by making a small web page that loads the IMG urls (e.g. http://xymon.mydomain.com/xymon- cgi/hobbitgraph.sh?host=server1.mydomain.com,server2.mydomain.com&service=la&graph_height=120&graph_width=576&color=green&nostale&action=view&graph=hourly)
It would be nice to have at tool to set up such views, but I think the better investment would be building a new web interface with a real framework which would make things like this easier to write ...
