+# Monitoring Sentinel-Kit Services
+
+Sentinel Kit includes a set of monitoring services that are enabled when the `internal-monitoring` profile is added to your `COMPOSE_PROFILES` in the `.env` file. These services rely on Prometheus, which is queried by Grafana.
+
+By default, Grafana is accessible at:  
+**[https://grafana.sentinel-kit.local](https://grafana.sentinel-kit.local)**
+
+### Access Credentials
+
+The access credentials for Grafana can be customized in the `.env` file:
+```bash
+GF_SECURITY_ADMIN_USER=sentinel-kit_grafana_admin
+GF_SECURITY_ADMIN_PASSWORD=sentinel-kit_grafana_password
+```
+### Initial Setup
+
+In its default configuration, Sentinel-Kit does not include any custom dashboards. However, the services for `fluentbit`, `mysql`, and `elasticsearch` are already configured within the platform. You can access all available metrics under the `metrics` section, and it is also possible to filter by service (jobs).

+
+### Importing Additional Dashboards
+
+You can import many additional dashboards from the official [Grafana website](https://grafana.com/grafana/dashboards/).
+
+### Performance Consideration
+
+**Warning**: On systems with limited memory or CPU resources, it is recommended to avoid enabling the `internal-monitoring` profile to ensure optimal performance.
