This repository contains the deployments of monitoring tools used across Open Food Facts infrastructure.

See Infrastructure / Observability for more documentation.

It contains Docker Compose deployments for services deployed on monitoring server:

• ElasticSearch (for gathering logs) running on port 9200 and 9300
• Kibana (to access elasticsearch thus logs) running on port 5601
• InfluxDB (metrics database) running on port 8086
• Grafana (dashboards and graphics from metrics) running on port 3000
• Prometheus (metrics and monitoring) running on port 9090
• AlertManager (automatic alerts triggering) running on port 9093

📝 there is another InfluxDB and Grafana for "business" metrics, see openfoodfacts-infrastructure:docker/metrics

It also contains exporters that should be deployed on each nodes (see docker-compose.node.yml):

• filebeat ¹ gather logs and send them to Elasticsearch
• cadvisor ² gather docker metrics
• node_exporter ³ gather host metrics

PS: if you modify this, please keep corresponding page in infrastructure up to date

• Alerts
• Prometheus Scrape targets
• Grafana Dashboards
• Grafana Datasources
• HTTP Probe Config
• Filebeat Config

You can first start the blackbox exporter service: docker compose up blackbox-exporter Look at the log, it may tell about errors in the config.

You can then test a probe manually, you must pass as parameter the target (the URL to probe), and the module used to probe it. Adding debug=true will help you debug the probe.

For example: http://127.0.0.1:9115/probe?target=https://prometheus.openfoodfacts.org/&module=http_probe_auth_monitoring&debug=true will probe http://prometheus.openfoodfacts.org with the http_probe_auth_monitoring module.

Look at the probe_success metrics to see if the probe succeeded.
