What does 'implemented PostgreSQL monitoring through Prometheus and Grafana' mean? Does it mean she deployed it in the company?

The phrase "implemented PostgreSQL monitoring through Prometheus and Grafana" usually means that the person has not just deployed these tools, but has organized the process of collecting, storing, and visualizing PostgreSQL database metrics within the company. This includes:

• Setting up exporters (e.g., postgres_exporter) to collect metrics from PostgreSQL.
• Configuring Prometheus to regularly query these metrics.
• Creating dashboards in Grafana for convenient data display and analysis.
• Possibly integrating with existing alerting systems.

In other words, it is not just installation, but a full integration of monitoring into the company's workflow and infrastructure.
