Zabbix::ServerScript - Simplify your Zabbix server scripts' environment.

SYNOPSIS

    #!/usr/bin/perl
    
    use strict;
    use warnings;
    use utf8;
    use Zabbix::ServerScript;
    
    my $opt = {
    	id => 1,
    };
    
    my @opt_specs = qw(
    	id=i
    );
    
    sub main {
    	Zabbix::ServerScript::init($opt, @opt_specs);
	Zabbix::ServerScript::return_value(1);
    }

    main();

DESCRIPTION

Zabbix::ServerScript is a module to simplify writing new scripts for Zabbix server: external scripts, alert scripts, utils, etc.

SUBROUTINES

init($opt, @opt_specs)

Initializes variables, sets logger, API, etc.

If specified, the first argument must be hashref, which can have the following keys:

$opt = {
	config => q(path/to/local/config.yaml),
	console => 0, 				# should the script log to STDERR or not
	verbose => 0, 				# increase verbosity. By default, script will log only WARN messages and above.
	debug => 0, 				# Enable debug mode.
	logger => q(Zabbix.ServerScript), 	# Log4perl logger name
	api => q(),				# name of Zabbix API instance in global config
	id => q(),	 			# unique identifier of what is being done, e.g.: database being checked
	unique => 0, 				# only one instance for each $opt->{id} is allowed
	daemon => 0, 				# daemonize during initialization. See Proc::Damon for details
}

If specified, the 2nd argument must be array of options descriptions, as for Getopt::Long::GetOptions.

The following options descrtiptions are included by default (see their meanings above):

verbose|v+ # --verbose (supports bundling, e.g. -vvv)
debug
daemon
console

Initializes the following global variables:

$logger

Log4perl instance

$config

hashref contais both local (script-specific) and global config data.

Default global config is located at Zabbix/ServerScript/DefaultConfig.pm.

User can generate its own global config and store it into Zabbix/ServerScript/Config.pm. Config.pm is preferred over DefaultConfig.pm.

Global config data can be accessed through $Zabbix::ServerScript::Config and $config->{global} variables.

Script-specific config is searched within $Zabbix::ServerScript::Config->{config_dir} path. Only YAML is currently supported for script-specific configs.

$config = {
	global => {
		config_dir => q(/path/to/local/config/dir),
		log_dir => q(/tmp),
		...,
	},
	local_item1 => ...,
	local_item2 => ...,
}
$zx_api

Zabbix::ServerScript::API object

return_value($value)

Prints $value to STDOUT and exits. Throws an exception if $value is not defined.

store_cache($cache, $cache_filename)

Stores cache to file using Storable module. $cache_filename is optional.

retrieve_cache($cache_filename)

Retrieves cache from file using Storable module. $cache_filename is optional.

connect_to_db($dsn, $user, $password)

Connects to database via unixODBC. $dsn is mandatory. Returns database handle or throws an exception on failure.

send($data_structure, $trapper_host, $trapper_port)

Send data to Zabbix trapper like zabbix_sender does. $data_structure is mandatory. $trapper_host and $trapper_port are optional, values from global config's 'trapper' section are used by default. Returns server response on success or throws an exception on failure. $data_structure must be either hashref or arrayref of hashrefs.

Each of hashref must be like:

{
	host => q(Linux host),	# hostname as in Zabbix frontend
	key => q(item_key),
	value => 1,
	clock => time,		# unix timestamp, optional
}

create_config

Creates Config.pm from DefaultConfig.pm.

Usage:

perl -MZabbix::ServerScript -e create_config
