Re: [hobbit] Graphing iostat on Linux systems?


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,

	martin

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:

1. 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. 

2. Cleaned up the regex a bit
3. 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.
