[hobbit] Graphing iostat on Linux systems?
Hi Martin,
thanks for the link (and thanks to the programmer of linux-iostat), I've installed it (with some additions/changes, see below) as described, and it works and shows what I need, :-). I attach my version of the script to this mail, since I made some edits:
- Added my "preamble" which I use in every extension script:
===============/snip/====================== my $TEST = "iostat"; (...) my $HOST = $ENV{"MACHINE"}; $HOST =~ s/(.*),.*,.*$/$1/; if (system("$ENV{'BBHOME'}/bin/bbhostgrep $TEST | grep $HOST > /dev/null 2>&1") != 0) { print "Not running on $HOST..." if $debug; exit 0; } ==============/snap/========================
With this, I can have the same scripts and config files on all systems (helps to keep things up2date), and just add the appr. entry (in this case, iostat) to the host part in bb-hosts ti run the script on a particular host.
- Cleaned up the regex a bit
- As we're using drbd (DistributedRemoteBlockDevice, often used with Linux-HA), I added "drbd" to the devices list.
Maybe someone can use my version, or get some ideas from it.

Hi all,
I'd like to use iostat for performance monitoring, and include its output in the Hobbit pages. I've found an old post about it, but it seems that the URL mentioned there (http://www.docum.org/twiki/bin/view/Hobbit/LinuxIostatGraphs) is no longer valid. Any ideas where I can get it?
Thanks,

Hi, Harald !
thanks for the hint with drdb !
Hmm, .. but dont't understand your "preamble", if i use your script, it seem's that the script think, that it's serverside-script ... ;-)
[it-hobbit2] /usr/lib/hobbit/client # bin/bbcmd ext/new_linux-iostat.pl 2009-04-06 23:56:55 Using default environment file /usr/lib/hobbit/client/etc/hobbitclient.cfg 2009-04-06 23:56:55 Cannot load bb-hosts, or file is empty Not running on it-hobbit2...
[it-hobbit2] /usr/lib/hobbit/client #
.. but it isn't one ...
What's is missing in my enviroment ?
thanks & cheers,

Hi Martin,
in our setup, we have a complete copy of the bb-hosts file on all clients in $BBCLIENTHOME/etc, which we use to control which external client script should run on which client. We have pre-compiled clients for all systems on the Hobbit server, including all config files, which are stored as tarballs. When I'm setting up a new client, I just add the appr. lines in the server's bb-hosts file, copy the new bb-hosts to the tarballs (we're planning to use something like rcsvi in the future to automate this step), and then execute a script on the server which uses scp and ssh to contact the new client, copy the tarball, untar it and start the client. Hope this sheds some light on the preamble, :-).

Ok, that explains , why it's thinking to be server-side-script :-)
