  1. nstall fail2ban-exporter:





bash






git clone https://github.com/bodges/fail2ban_exporter.git cd fail2ban_exporter make




  1. Run the exporter:





bash






./fail2ban_exporter




  1. Configure Prometheus to scrape the Fail2Ban exporter by adding it to your prometheus.yml:





yaml






scrape_configs: - job_name: 'fail2ban' static_configs: - targets: ['localhost:9117'] # Adjust the port where your exporter is running





✅ 2. Integrating 축구중계 Cloudflare or AWS WAF Unban Actions with Prometheus


To integrate unban actions (whether from Cloudflare or AWS WAF) into Prometheus, we need to create custom metrics based on unban events.



Step 1: Create a Custom Metric for Unban Events


You can use Prometheus client libraries (e.g., Python, Go) to create custom metrics whenever an IP is unbanned from Cloudflare or AWS WAF.


Here’s an example using Python and the Prometheus client library:





  1. Install the Prometheus client:





bash






pip install prometheus_client




  1. Write a simple script to track unban events:





python






from prometheus_client import start_http_server, Counter import requests import time # Create a counter to track unban events unban_counter = Counter('cloudflare_unban_events', 'Number of IPs unbanned from Cloudflare', ['ip']) def unban_ip(ip): # Send unban event to Cloudflare API url = "https://api.cloudflare.com/client/v4/zones/YOUR_ZONE_ID/firewall/access_rules/rules/<rule_id>" headers = {"Authorization": "Bearer YOUR_API_TOKEN"} response = requests.delete(url, headers=headers) # Increment the unban counter unban_counter.labels(ip=ip).inc() # Start Prometheus server to expose metrics start_http_server(8000) # Simulate unban events while True: ip_to_unban = "192.168.1.1" # Example IP unban_ip(ip_to_unban) time.sleep(60)




  1. Expose metrics to Prometheus:






  • The script will expose metrics at http://localhost:8000/metrics.




  • Prometheus can scrape these metrics



    축구중계  


    like any other endpoint.






  1. Update Prometheus to scrape this custom metric by adding it to prometheus.yml:





yaml






scrape_configs: - job_name: 'cloudflare_unban' static_configs: - targets: ['localhost:8000'] # Your unban script





✅ 3. Visualizing the Data in Grafana


Now that your metrics are available in Prometheus, you can use Grafana to create dashboards to visualize the unban events and Fail2Ban-related data.



Step 1: Set Up Grafana Dashboards




  1. Log into Grafana (http://localhost:3000)




  2. Add Prometheus as a data source.




  3. Create new dashboards with panels that visualize:





    • Fail2Ban bans/unbans




    • Cloudflare/AWS WAF unban events






Example query in Grafana to show the number of unbanned IPs:




nginx






cloudflare_unban_events_count


You can create time series graphs, tables, and alerts that show how often IPs are being banned/unbanned over time.
