Re^4: Not sure how to populate a hash

Thanks so much for your help guys. I mostly get this now!

Just one last question. If I wanted to return the attributes of one of the servers as a hash, how do I get to that data?

So in other words, I want to a create a simple hash %server_properties which name value pairs of one of the servers?

This creates a copy (NOT an alias i.e. writing to it won't change the original data) `%server_properties = %{$nodemetrics{server1}}` Otherwise `$h_server1 = $nodemetrics{server1}` (like already shown) is the same hashref, which can be safely changed `$h_server1->{cpu}=100` or alternatively `$$h_server1{cpu}=100` see `perlref` and `perldsc` for details!

%server_properties = %{$nodemetrics{server1}}

Otherwise

$h_server1 = $nodemetrics{server1}

(like already shown) is the same hashref, which can be safely changed

$h_server1->{cpu}=100 or alternatively $$h_server1{cpu}=100

see perlref and perldsc for details!
