PROMETHEUS ALERTING
We already saw multiple Custom Resourse Definitions (CRDs) that the Prometheus Operator gives us. The Alertmanager is also a CRD. The definition of this instance is very simple. The complete code for this setup is found on this branch on github.

KUBERNETES AND PROMETHEUS
Prometheus will be a separate pod in your cluster that will scrape given endpoints for information. In this first section we will get this pod running. All code for this section is found on github. Let’s take a look at the Kubernetes resource definition of Prometheus:

What is the Role of AI in DevOps?
The increasing complexity of modern systems led to the rise of AIOps (Artificial Intelligence for IT Operations) and observability practices. AIOps leveraged machine learning algorithms to automate problem detection, analysis, and resolution. Observability focused on gaining insights into system behaviour through metrics, logs, and traces. As a result, tools like Prometheus, Grafana, and ELK stack (Elasticsearch, Logstash, Kibana) gained popularity.

Are there any good solutions for analyzing firewall logs to generate analytics/reports?
My only experience with NetFlow collection is on my home firewall/router running pfSense Community Edition, which is free to download and can be installed on a wide assortment of X86 hardware. I installed the Softflowd package, which exports NetFlow data to a dedicated Elasticsearch/Logstash/Kibana (ELK) server on my LAN. I believe Security Onion and ElastiFlow also can be NetFlow collectors.

Traffic logging at home without router
Buy an enterprise-class, wired router like the Negate 2100 ($349 USD), which runs pfSense, and configure the Deco AXE5400 device(s) to operate in Access Point Mode. Then install the Softflowd package through the pfSense web UI. Softflowd will collect and export NetFlow data to a NefFlow collector, which is the separate computer/VM/container referred to above, running software like Security Onion, ElastiFlow, or Elasticsearch/Logstash/Kibana (ELK).
