=head1 NAME
Zabbix::Utils -- Useful miscellanea related to Zabbix
=head1 DESCRIPTION
This is a collection of miscellaneous things useful to have in the event that
you're doing something with the Zabbix::API distribution.
=head1 FUNCTIONS
None so far.
=head1 EXPORTS
None by default.
=head2 EXPORTABLE
=over 4
=item RE_FORMULA
This constant (in the C<use constant> sense) is a regular expression that will
match against parts of formulas of calculated items thusly:
use Zabbix::Utils qw/RE_FORMULA/;
# interpolating constants is problematic
my $regexp = RE_FORMULA;
my $formula = 'last("MyROuter2:ifHCInOctets5")+last("MyROuter2:ifHCInOctets23")';
while ($formula =~ m/$regexp/g) {
print Dumper(\%+);
}
Which should output:
$VAR1 = {
'function_call' => 'last("MyROuter2:ifHCInOctets5")',
'function_args_quote' => '"',
'item' => 'ifHCInOctets5',
'function_args' => 'MyROuter2:ifHCInOctets5',
'host' => 'MyROuter2'
};
$VAR1 = {
'function_call' => 'last("MyROuter2:ifHCInOctets23")',
'function_args_quote' => '"',
'item' => 'ifHCInOctets23',
'function_args' => 'MyROuter2:ifHCInOctets23',
'host' => 'MyROuter2'
};
Item arguments (system.uptimeB<[minutes]>) appear in C<item_arg> which is not
represented here (fixme!).
You'll have noticed that this makes use of the excellent "named capture buffers"
feature, which means you need Perl 5.10 or higher.
