Requrements

Zabbix 3.4 (I dont check backward compability with Zabbix 3.0 - 3.2)
Python 3.4.3 and above
libs: Pillow, py-zabbix, ruamel.yaml

Install

    sudo apt-get install python3-pip python-pip python3-pil
    sudo pip3 install py-zabbix
    sudo pip3 install ruamel.yaml==0.14.12
    unzip Zabbix-Network-Weathermap.zip -d /opt
    chown -R zabbix:zabbix /opt/Zabbix-Network-Weathermap/*
    chmod a+x /opt/Zabbix-Network-Weathermap/starter.py
    chmod a+x /opt/Zabbix-Network-Weathermap/weathermap.py
    cp /opt/Zabbix-Network-Weathermap/template/userparameter_weathermap.conf /etc/zabbix/zabbix_agentd.d/

Copy /template/userparemeter_weathermap.conf to /etc/zabbix/zabbix_agentd.d/ and reload zabbix-agent
Import template /template/weathermap.xml to zabbix
Add Template Weathermap to host where use zabbix agent (for example use host zabbix server)
Create new user with permissions Zabbix Admin
User must have read-only or read-write access to hosts and hosts groups present in map
Go to Zabbix -> Configuration -> Template Weathermap -> Macros:

{$SCANFILE} - When map config exist. If you change map remove host or change position host, configuration will be updated in accordance with changes on the map.

{$SCANMAP} - First time scan map, config file not exist. Create file with map configuration.

{$UPDATE} - Only create image, like old style Network Weathermap.

{$UPLOAD} - Create and upload image to Zabbix.
Check Zabbix -> Configuration -> Hosts -> Host with Weathermap template -> Applications -> Weathermap -> Items -> Status
Create file with map configuration:
```
  weathermap.py -s mapname1 mapnameN -z http://zabbix.example.com -l admin -p admin
```
OR

Zabbix -> Template Weathermap -> Macros -> {$SCANMAP} -> Value
Open file /opt/Zabbix-Network-Weathermap/mapcfgs/mapname1.yaml and set hostname and itemin, itemout. If you set visible name, then use visible name instead hostname.

         link-1:
           node1: node-Router
           node2: node-Switch
           name1: R1
           name2: SW1
           width: 15
           hostname: Router
           #itemin/itemout = item key
           itemin: ifHCInOctets[ge-0/0/0]
           itemout: ifHCOutOctets[ge-0/0/0]

Create map image and upload it to Zabbix:
```
  weathermap.py -m mapname1.yaml -u  
```
OR

Zabbix -> Template Weathermap -> Macros -> {$UPLOAD} -> Value
Set Zabbix -> Monitoring -> Maps -> mapname1 -> Properties -> Background image -> mapname1

# Examples:
# When map config exist. If you change map remove host or change position host, 
# configuration will be updated in accordance with changes on the map.
weathermap.py -s mapname1 mapnameN -f

# First time scan map, config file not exist. Create file with map configuration.
weathermap.py -s mapname1 mapnameN -z http://zabbix.example.ru -l login -p password

# Only create image, like old style Network Weathermap.
weathermap.py -m mapname1.yaml mapnameN.yaml -i /var/www/weather

# Create and upload image to Zabbix.
weathermap.py -m mapname1.yaml mapnameN.yaml -u

starter.py run weathermap.py and return execution time.

For auto update image or rescan map you can use cron, systemd or Template Weathermap.

Notice

Zabbix 3.4.x do not refresh background image on map. FIX!

Zabbix API performance is low. Zabbix agent run weathermap.py. Weathermap.py can be terminated by timeout, set in zabbix_agentd.conf.

Decision:

Increase the timeout for example: zabbix_agentd.conf set Timeout=10
One item to one map in Template Weathermap
Use cron to run the scripts

If you need convert from old style config to YAML format, use converter.py

user@pc:~$ converter.py /path-to-old-style-cfg/map.cfg
user@pc:~$ ls /path-to-old-style-cfg
map.cfg
map.yaml

For a better look of map, set the link type a dot and color like background.
