# Zabbix plugin for PHP Network Weathermap
2+
3+
This plugin inegrates Zabbix into PHP Weathermap, using Zabbix API.
4+
5+
## Installation
6+
7+
Copy the content of the `lib` folder into the `lib` folder of your PHP Weathermap installation.
8+
9+
### Configuration of the new datasource for traffic
10+
11+
You have to configure the following parameters in yoour weathermap file :
12+
13+
* `SET zabbix_user username` : Zabbix username
14+
* `SET zabbix_password password` : Zabbix password
15+
* `SET zabbix_url http://zabbix/zabbix/api_jsonrpc.php` : the URL to the Zabbix API
16+
* `SET zabbix_key name` : the attributes you want to use to select items in the configuration
17+
18+
You can connect with a guest account by ommitting the password parameter :
19+
20+
```SET zabbix_user guest```
21+
22+
### Configuration of the Zabbix graphs integration
23+
24+
You have to configure the following parameters in yoour weathermap file :
25+
26+
* `SET post_zabbix_graphs 1` : enable the overlib graphs
27+
* `SET post_zabbix_graph_links 1` : enable the links to the graph page in Zabbix
28+
* `SET post_zabbix_graph_base_url https://zabbix/zabbix/chart2.php` : the URL to the Zabbix frontend
29+
* `SET post_zabbix_graph_width 420` : the graphs width in pixels
30+
* `SET post_zabbix_graph_height 150` : the graph height in pixels
31+
* `SET post_zabbix_graph_period 86400` : the graph period in seconds
