Improve performance of zabbix_host

[baurmatt]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: Puppet 5.5.6
• Ruby: Ruby 2.4.3
• Distribution: Ubuntu 16.04
• Module version: Current master

How to reproduce (e.g Puppet code you use)

(The hosts are already created in Zabbix)

$range = range(0, 3000)

$range.each |$i| {
  zabbix_host { "test${i}":
    templates    => ['Template OS Linux'],
    ipaddress    => '127.0.0.1',
    port         => 10050,
    use_ip       => true,
    group        => 'testhosts',
    group_create => true,
    zabbix_url   => 'zabbix-host.example.de',
    zabbix_user  => 'Admin',
    zabbix_pass  => 'zabbix',
  }
}

root@mbaur-zabbix:~# puppet apply test.pp

What are you seeing

The performance of zabbix_host is really poor. The problems seems to be, that Puppet does, for the a single host as definied above, 7 API calls. If there would be an additional template the API call count goes up to 13 and increases even further for more templates.

What behaviour did you expect instead

Puppet does 2 API calls:

• login
• get host with templates
