NAME

Zabbix::Utils -- Useful miscellanea related to Zabbix

DESCRIPTION

This is a collection of miscellaneous things useful to have in the event that you're doing something with the Zabbix::API distribution.

FUNCTIONS

None so far.

EXPORTS

None by default.

EXPORTABLE

RE_FORMULA

This constant (in the 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.uptime[minutes]) appear in 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.

RE_EXPRESSION

Like RE_FORMULA, this matches against trigger expressions:

use Zabbix::Utils qw/RE_EXPRESSION/;

my $regexp = RE_EXPRESSION;

my $expression = '{www.zabbix.com:system.cpu.load[all,avg1].last(0)}>5';
$expression =~ m/$regexp/;

print Dumper(\%+);

Which should output:

$VAR1 = {  };
