[hobbit] Random hobbit newbie questions

[White, Bruce]

I think it is based on the result of a uname -s command.  So Redhat comes
back as Linux, HPUX is HP-UX, Solaris is SunOS, etc.  I believe this also
then matches the actual client script the hobbit client runs as in
hobbitclient-hp-ux.sh.

Subject: [hobbit] Random hobbit newbie questions
 
Hi Everyone, I'm relatively new to Hobbit.  I like it a lot, but I do have a
few random questions.  I've been reading the documentation a lot and haven't
found the answers, so I hope the answers don't turn out to be "see the man
page". :)
 
I have to say I really like the documentation to Hobbit.  At first glance it
seems a bit short, but on reading it I find that it manages to be packed
with information which is written in a nice concise, efficient, jargon-free,
and human-readable way.  The comments in the config files are also
excellent, although sometimes the information in there is slightly different
from what's in the documentation page for that file - sometimes there's info
in one place that isn't in the other.  I wish more documentation in the IT
field were written like this.  My only suggestion is that it would be
helpful for us new folks to have some kind of general overview that
describes (or better yet, shows in a flowchart) how data flows between
client, server, the various tests, the web server, how the various config
files fit in, and so on.  The information is currently in there but it takes
a good bit of reading and experimenting before you really start to "get it".
 
Questions:
 
1) In the hobbit-clients.cfg file, I this is in the comments:
 
 
#             Defaults: MEMPHYS warnlevel=100 paniclevel=101 (i.e. it will
never go red)
#                       MEMSWAP warnlevel=50 paniclevel=80
#                       MEMACT  warnlevel=90 paniclevel=97
#  Note: The words "PHYS", "ACT" and "SWAP" are also recognized.
And then later on, there is this bit:
 
# These are the built-in defaults.
# SWAP    20 40
# MEMSWAP 50 80
 
Is there a difference between MEMSWAP and SWAP?  If not, why is it listed
twice in the defaults?  If so, what is the difference?
 
 
2) In the documentation page for hobbit-clients.cfg, there is this
statement:
 
"CLASS=classname  - Rule match by the client class-name. You specify the
class-name for a host when starting the client through the "--class=NAME"
option to the runclient.sh script. If no class is specified, the host by
default goes into a class named by the operating system."
 
Unfortunately I can't find any details about what the default names of the
"classes named by the operating system" are, so I don't know which strings
to put after "CLASS=" in my hobbit-clients.cfg file.  Is there a list
somewhere?
 
 
3) There are a couple columns in the default configuration that I don't
want, like "files".  On the page in question, the status icon for every
system is "clear" (white).  I want to use the "drop" option to the bb
command to do this.  I issued this command for every host on the page in
question:
 
bb localhost "drop <hostname> files"
 
That works for a minute or two.  On the next page refresh, almost all of the
hosts have the column empty (just a dash), but a few of them are back to
"clear" already.  After one or two refreshes, all the systems are back at
clear status.  How can I get hobbit to drop the column forever, permanently,
completely, without leaving old history files around and stuff?
 
Thanks for any tips!
