[log]
level = warn

Database optimization significantly impacts performance, especially for installations with extensive historical data. Regular maintenance tasks include index optimization, data pruning, and connection pool tuning.

Best Practices for Production

Implement regular backup procedures for both configuration files and dashboard definitions. Export important dashboards as JSON files and store them in version control systems for disaster recovery purposes.

Monitor Grafana itself using built-in metrics endpoints. Enable the metrics endpoint in the configuration file:

[metrics]
enabled = true

Configure external monitoring systems to track Grafana performance, including response times, memory usage, and query execution duration.

Scale deployments using load balancers and database clustering for high-availability requirements. Document configuration changes and maintain deployment procedures for consistent environments.

Troubleshooting Common Issues

Installation Problems

Repository configuration errors commonly occur during initial setup. Verify repository files contain correct URLs and GPG key references. Remove and recreate repository configurations if corruption is suspected:

sudo rm /etc/yum.repos.d/grafana.repo
# Recreate the repository file with proper configuration

GPG key import failures prevent package installation and updates. Manually import keys using alternative methods:

curl -s https://rpm.grafana.com/gpg.key | sudo gpg --import

Dependency conflicts arise when system packages have incompatible versions. Resolve conflicts by updating system packages or using DNF’s conflict resolution features.

Service and Connectivity Issues

Service startup failures require systematic log analysis. Examine Grafana logs using multiple approaches:

sudo journalctl -u grafana-server --since "1 hour ago"
sudo tail -f /var/log/grafana/grafana.log

Common startup problems include configuration file syntax errors, permission issues, and port conflicts. Verify configuration syntax using Grafana’s built-in validation tools.

Port binding conflicts occur when other services use port 3000. Identify conflicting processes:

sudo netstat -tulnp | grep :3000
sudo lsof -i :3000

Change Grafana’s port configuration or stop conflicting services to resolve binding issues.

Performance and Configuration Issues

Slow dashboard loading indicates performance bottlenecks in queries, data sources, or system resources. Enable query logging to identify expensive operations:

[log]
filters = query.duration:debug

Database connection problems manifest as data source errors or timeout messages. Verify connectivity using command-line database clients and network troubleshooting tools.

Authentication and permission issues prevent user access or limit functionality. Review user roles, organization settings, and authentication provider configurations systematically.

Log Analysis and Debugging

Grafana maintains detailed logs in /var/log/grafana/grafana.log by default. Configure log levels and output formats to capture necessary debugging information:

[log]
mode = console file
level = debug
format = json

Common error patterns include database connection failures, plugin loading errors, and authentication timeouts. Use log analysis tools like grep, awk, and journalctl to filter and analyze log entries effectively.

Enable debug logging temporarily for intensive troubleshooting sessions, but return to standard logging levels in production to prevent excessive disk usage.

Security Considerations and Hardening

Essential Security Measures

Change all default credentials immediately after installation, including the admin account password and any default API keys. Implement strong password policies through configuration settings:

[security]
admin_user = administrator
admin_password = $__env{GRAFANA_ADMIN_PASSWORD}

Implement HTTPS for all communications by configuring SSL certificates. Generate or obtain SSL certificates and update the server configuration:

[server]
protocol = https
cert_file = /etc/grafana/ssl/grafana.crt
cert_key = /etc/grafana/ssl/grafana.key

Restrict network access using firewall rules and network policies. Limit source IP addresses for administrative access and implement VPN requirements for sensitive environments.

Advanced Security Configuration

Configure authentication backends including LDAP, OAuth, or SAML for enterprise integration. These systems provide centralized user management and enhanced security controls:

[auth.ldap]
enabled = true
config_file = /etc/grafana/ldap.toml

Implement role-based access control (RBAC) to limit user permissions based on job functions. Create custom roles with specific dashboard and data source access restrictions.

Secure API access through token management and IP-based restrictions. Regularly rotate API tokens and audit their usage patterns for security compliance.

Configure security headers and additional protections:

[security]
cookie_secure = true
cookie_samesite = strict
content_security_policy = true

Maintenance and Updates

Regular Maintenance Tasks

Keep Grafana updated using DNF package manager commands. Check for available updates regularly:

sudo dnf check-update grafana
