in reply to Swapping names of list while keeping the contents as it is.

Another method that reads the data in paragraph mode, splits into first element and remaining elements within lines in one map then swaps the first elements of the two lines and rejoins things up in a second, finally joining the pairs of lines into paragraphs again.

$ perl -Mstrict -Mwarnings -E ' > open my $fh, q{<}, \ <<EOF or die $!; > jay 21 34 56 > bob 12 39 > > jay 11 10 > bob 14 > > jay 190 > bob 13 > EOF > > say join qq{\n\n}, do { > local $/ = q{}; > map { > ( $_->[ 0 ]->[ 0 ], $_->[ 1 ]->[ 0 ] ) > = > ( $_->[ 1 ]->[ 0 ], $_->[ 0 ]->[ 0 ] ); > join qq{\n}, map { join q{ }, @$_ } @$_; > } > map { > chomp; > [ map { [ split m{\s}, $_, 2 ] } split m{\n} ]; > } > <$fh>; > };' bob 21 34 56 jay 12 39 bob 11 10 jay 14 bob 190 jay 13 $

I hope this is of interest.

Cheers,

[Discipulus]: we too; using opsview alarms
[marto]: the key word: outsourcing ;)
[Corion]: marto: Yeah, feels like that ;) You could set up the cronjob that auto-creates tickets :-))
[marto]: the ticketing system does not accept calls via email, nor has it a working API. It's tied into Active Directory for authentication and the Solaris boxes aren't on that domain
[Corion]: The one thing I haven't figured out a solution to is how to get an edge-trigger instead of sending an email every 5 minutes if the usage is above 90%. I want one mail when it goes over 90% but no more emails as long as it stays between 90% and 95%.
[Corion]: marto: Clever! ;)
[Corion]: You can only reach me by pager
[Corion]: Maybe the solution would be to launch a cron job every minute that takes two measurements a minute apart and sends a mail if the usage is below on the first and above threshold on the last measurement
[marto]: that's essentially it :)
[marto]: I think the long term solution would be to have sysadmins that do their job, so I don't have to do everything :P
