Webhook that sends alerts to a Zabbix server via trapper items.
You can create your Zabbix Hosts/Items/Triggers yourself - which gets tedious fast - or you can use https://github.com/gmauleon/alertmanager-zabbix-provisioner to pull the list of items and alerts directly from Prometheus and its Alertmanager.
However, if your Prometheus Alertmanager is not (automatically) reachable from your alertmanager-zabbix-webhook location, or you have no place to pull from Prometheus AND push to Zabbix server at the same time, or you have multiple remote Prometheuses and/or Alertmanagers, then you might use the Zabbix template that uses Low-Level-Discovery rules and automatically learns and populates your Zabbix targets for you, based on the alerts that it receives via this webhook: P_Prometheus.xml.
Have a look at the default config.yaml for the possible parameters
