Prometheus Zabbix Template Generator

This is a proof-of-concept that converts the output of a Prometheus exporter into a Zabbix template with generated items.

A conversion can be performed in the following way:

1. Gather the prometheus output (alternatively use the --url parameter in step 4)

   curl http://kube-prometheus-stack-prometheus.umon:9090/metrics > example/prometheus_exporter_dump.txt
   

2. Create an example template in zabbix
3. Download it in JSON and add replacement markers to it, see zabbix_template_prometheus_exporter.json
   • PROM2ZABBIX_TEMPLATE_NAME: The name of the template
   • PROM2ZABBIX_ITEM_NAME: The displayed name of the template
   • PROM2ZABBIX_ITEM_KEY: The item key, adapted label to comply to zabbix item name restrictions
   • PROM2ZABBIX_ITEM_LABEL: The prometheus label
4. Execute the conversion, this selects only items which match to the specified filter regex

   ./prom2zabbix \
      --template example/zabbix_template_prometheus_exporter.json \
      --dump example/prometheus_exporter_dump.txt \
      --target_template example/zabbix_template_prometheus_exporter_generated.json \
      --filter "promhttp_metric_handler_requests_total" \
      --name "Prometheus"
   

5. Upload the generated template to zabbix and check the result
6. Repeat the process for other items and select the option "Delete missing" of the existing items
