Graph LLD

This is Zabbix 3 plugin to allow graph multiple LLD items on the same chart (ZBXNEXT-927).
For example you might have some disk discovery, which creates item free disk space, % for each disk found. With this plugin now you can create and automatically keep in sync graph with all the items on single chart:

Interface for this looks mostly the same as for usual Graph prototype:

with additional field for Template. You can create multiple such Graphs for different Templates and ItemPrototypes. Also you can mix different ItemPrototypes of same Template on one chart. When Graph is created such actions possible:

• Run - create standalone Graphs for selected prototype(s)
• Clean - remove generated standalone graphs from all hosts in Template
• Delete - same as Clean, but also removes Graph entry

How it works

When you executing Run action this happens:

• Search for Hosts having this Template assigned
• For each Host - search LLD items derived from ItemPrototype(s) selected for Graph
• Create or update standalone Graph on Host with found Items (will update only if something changed)

Installation

Unzip (or clone) to root of your zabbix-frontend-php folder (which is /usr/share/zabbix for Debian)
Then add to Main Menu with something like this:

+++ include/menu.inc.php	2016-07-24 13:04:06.000000000 -0700

Now you can create new Graphs and apply them in Zabbix Web Interface. But as time goes - discovery would find new items (or remove missed ones) and standalone Graphs would become outdated. One solution is to press Run to update them time to time. Better solution is to configure cron job, for this fix /glld/glld.cli.php with service user creds:

#!/usr/bin/env php
<?php PHP_SAPI === 'cli' or die();
$auth=['user' => '', 'password' => '']; //fix this with valid user/password having Write access to Hosts
...

Note that user should have write access to Host on which you going to create Graphs.
Check it executing glld/glld.cli.php from shell (you might need to do chmod +x glld/glld.cli.php)
Then add it to cron, for example via such /etc/cron.d/zabbix-glld-update:

#m h dom mon dow user     command
47 * *   *   *   www-data /usr/share/zabbix/glld/glld.cli.php >/dev/null

This would update graphs once per hour (on each 47th minute)
