Or use the NOCOLUMNS option in the bb-hosts file:

"NOCOLUMNS:column[,column] Used to drop certain of the status columns generated by the Hobbit client. column is one of cpu, disk, files, memory, msgs, ports, procs. This setting stops these columns from being updated for the host. Note: If the columns already exist, you must use the bb(1) utility to drop them, or they will go purple."

3. Try a "group-except files <group-name>" in your bb-hosts file.
   That's what I did for my files test anyway.

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!
