PostgreSQLExporterErrors #
Meaning #
Alert is triggered when the PostgreSQL exporter reports errors when scrapping metrics.
Impact #
The monitoring system is degraded, some metrics may not be collected anymore. Alerts relying on these metrics will not trigger.
Diagnosis #
Look at Prometheus PostgreSQL exporter logs. The error messages (level=error) should explain why the exporter can’t scrape metrics.
Usually, this is linked to misconfiguration of the exporter.
Mitigation #
Identify and fix the exporter misconfigurations.
