Getting started #

Requirements

• Helm

• Prometheus Kubernetes operator

  1. ruleSelector must be enabled (documentation)

  2. serviceMonitorSelector must be enabled for ServiceMonitor (documentation)

Steps

1. Deploy Prometheus RDS exporter and/or Prometheus PostgreSQL exporter

2. Deploy charts with helm

   # RDS alerts
   helm install prometheus-rds-alerts-chart oci://public.ecr.aws/qonto/prometheus-rds-alerts-chart \
   --version latest \
   --namespace monitoring
   

   # PostgreSQL alerts
   helm install prometheus-postgresql-alerts-chart oci://public.ecr.aws/qonto/prometheus-postgresql-alerts-chart \
   --version latest \
   --namespace monitoring
   

3. Connect to Prometheus to check that the rules are correctly loaded (https://<your_prometheus_url>/rules)

Requirements

• Helm

• Prometheus server

Steps

1. Deploy Prometheus RDS exporter and/or Prometheus PostgreSQL exporter

2. Generate Prometheus rule configuration files

   # Generate RDS rules in /etc/prometheus/rds.rules.yaml
   helm template oci://public.ecr.aws/qonto/prometheus-rds-alerts-chart \
   --version latest \
   --set format=PrometheusConfigurationFile \
   > /etc/prometheus/rds.rules.yaml
   

   # Generate PostgreSQL rules in /etc/prometheus/postgresql.rules.yaml
   helm template oci://public.ecr.aws/qonto/prometheus-postgresql-alerts-chart \
   --version latest \
   --set format=PrometheusConfigurationFile \
   > /etc/postgresql.rules.yaml
   

3. Add files to the rule_files parameter in the Prometheus configuration file

   rule_files:
     - /etc/prometheus/rds.rules.yaml
     - /etc/prometheus/postgresql.rules.yaml
   

4. Reload Prometheus configuration

5. Connect to Prometheus to check that the rules are correctly loaded (https://<your_prometheus_url>/rules)
