[Orca-users] clear multiple disk run data

[Julian R C Briggs]

Dear All,

If, like us, you are unable to plot:

Disk Run Percent
Disk Space Percent Usage
Disk Inode Percent Usage

because you have multiple graphs of each, then you may find this
useful.

To throw away old Disk (Run, Space, Inode) data (so we can plot
single graphs), do this:

cd /export/orca
rm orcallator/*/*{disk_runp_,mntP_,mntp_}*.rrd
orcaproc */orcallator-*[0-9]
perl -pi.bak -e 's/\s+(disk_runp_|mntP_|mntp_)//og' orcallator/orca.state

}

#Split into fields (including LEADING space of field)
@FIELD = /(\s*\S+)/og;

#Identify fields to Keep
if (/^\s?timestamp/){
    @KEEP=();
    foreach $I (0 .. $#FIELD){
	push(@KEEP, $I) unless ($FIELD[$I] =~ /$REGEXP/o);
    }
} 

print @FIELD[@KEEP];
