docs(katana): update monitoring example #2942
Conversation
WalkthroughOhayo, sensei! The pull request introduces updates to the monitoring infrastructure for the Katana project. The changes primarily focus on updating Docker images for services like Katana, Prometheus, and Grafana, and configuring their respective settings. The modifications include version bumps for services, adjusting data source configurations in Grafana dashboards, and adding a fallback scrape protocol in Prometheus settings. Changes

1-7: Consider adding configuration comments, sensei!The configuration would benefit from documentation explaining:
- Why the fallback protocol is needed
- Which versions of Prometheus it supports
- When it might be triggered
scrape_configs: - job_name: katana metrics_path: "/" scrape_interval: 5s static_configs: - targets: ["host.docker.internal:9001", "localhost:9100"] + # Fallback protocol for compatibility with older metric formats + # Supported in Prometheus v3.x.x and later fallback_scrape_protocol: PrometheusText1.0.0crates/katana/monitoring/grafana/dashboards/overview.json (2)
2-2: Ohayo sensei! Consider adding datasource provisioning configuration.The empty
__inputsarray removes the variable-based datasource configuration. While this simplifies setup, it assumes the Prometheus datasource is already configured with the exact name "Prometheus".Consider adding a datasource provisioning configuration file to ensure the required datasource is automatically configured during deployment.
Line range hint
1830-1845: Consider enhancing instance variable configuration.The instance variable configuration uses a basic regex to extract instance names. This could be enhanced to:
- Add a meaningful default value
- Include instance labels or tags for better organization
- Add validation to ensure only valid instances are selected

18-18: Ohayo! Consider using non-root user for Prometheus.While updating to v3.1.0 is good, it's recommended to run Prometheus as a non-root user for better security.

104-104: Verify Prometheus datasource configuration.The hardcoded "Prometheus" datasource UID is used consistently across all panels. This change removes the flexibility of variable-based configuration but simplifies the setup.

✅ Verification successful
Ohayo sensei!
✓ Prometheus datasource configuration verified
The hardcoded "Prometheus" datasource name in the dashboard correctly matches the provisioned datasource configuration. The setup follows Grafana's best practices with proper Docker volumes and provisioning.

7-7: Ohayo sensei! Consider platform compatibility for Docker host resolution.The hardcoded URL
http://host.docker.internal:9090might not work on all platforms. While it works on Docker Desktop for Windows and macOS, Linux users might need additional configuration.Consider either:
- Using an environment variable for flexibility:
- url: "http://host.docker.internal:9090" + url: ${PROMETHEUS_URL:-http://host.docker.internal:9090}
- Or adding a note in the documentation about Linux configuration:

💡 Codebase verification
Ohayo sensei! Remove unsupported protocol configuration.
The fallback_scrape_protocol: PrometheusText1.0.0 configuration appears to be invalid or unsupported. This setting is not documented in the standard Prometheus configuration and could cause issues with metric collection. Please remove this line unless there's a specific requirement for it, in which case it should be documented in the monitoring setup guide.
🔗 Analysis chain
Ohayo sensei! Verify Prometheus version compatibility.
The addition of fallback_scrape_protocol is a good defensive measure, but we should ensure it's compatible with the Prometheus version being used (v3.1.0 according to the summary).

🛠️ Refactor suggestion
Secure configuration for Grafana environment variables.
The current setup exposes admin credentials in the compose file and enables anonymous access. While this might be fine for development, please consider:
- Using a
.envfile for sensitive values - Evaluating if anonymous access is really needed
Create a .env file:
GF_SECURITY_ADMIN_PASSWORD=your_secure_password
GF_SECURITY_ADMIN_USER=admin
GF_AUTH_ANONYMOUS_ENABLED=falseThen update the compose file:
environment:
- GF_DASHBOARDS_DEFAULT_HOME_DASHBOARD_PATH=/etc/grafana/provisioning/dashboards/overview.json
- - GF_SECURITY_ADMIN_PASSWORD=admin
- - GF_SECURITY_ADMIN_USER=admin
- - GF_AUTH_ANONYMOUS_ENABLED=true
+ - GF_SECURITY_ADMIN_PASSWORD=${GF_SECURITY_ADMIN_PASSWORD}
+ - GF_SECURITY_ADMIN_USER=${GF_SECURITY_ADMIN_USER}
+ - GF_AUTH_ANONYMOUS_ENABLED=${GF_AUTH_ANONYMOUS_ENABLED:-false}
