G''Day Folks,
I''d like to announce a new freeware tool, "DExplorer". It
runs a series of
DTrace scripts (all aggregations) that monitor generic system wide
activity, and saves the output in a .tar.gz file with a meaningful
structure,
http://www.opensolaris.org/os/community/dtrace/dexplorer
So now people can run a dexplorer and email the results! :-)
The idea came from David Visser, Christopher Wells, and several other guys
I met while in Melbourne, Australia last week. It''s a great idea - it
makes a lot of sense.
It currently runs 20 scripts, some producing fairly raw output. The output
itself would be suitable to run through analysers, I imagine it
wouldn''t
be hard to develop Perl wrappers that generated HTML reports (anyone?).
(The opensolaris website links to mine for the download - so far I
haven''t
convinced the opensolaris web server to accept uploads ("Manage
attachments" rejects all file types I''ve thrown at it so far)).
Enjoy!
PS. The DTraceToolkit is coming along nicely.

I wouldn''t worry so much as to html reports. You could just concatnate the results into a single file a put markers to grep on Cpu, Mem etc etc. A real kicker for Dtrace would be to create a realtime plugin for plotting results in say ''gkrellm''. ---Bob This message posted from opensolaris.org

I''m still somewhat eager to get some form of plotting from what a default Solaris install gives. A while ago I looked at this with DTrace in mind, and ended up writing a bunch of dtksh tools (they are on my website, oh - which includes xpong - how useful :). I do intend to have another crack at this, but I''m planning to go with Java instead. I''ll certainly consider the advantages of using something like gkrellm vs writing my own GUI plotter... PS. dtksh has some tiny bugs such that it goes haywire if you leave it running for a few hours - which is why I didn''t do a lot more with it. Now, if only Sun would OpenSolaris the /usr/dt/bin/dtksh code for me to fix up :-))) cheers, Brendan [Sydney, Australia]
