title: Probing kubernetes ingress to check health
body: <p>I have recently deployed an instance of promethus blackbox exporter to try to help monitor the status of the ingress in our clsuter. To do that i have set up a probe that uses the <strong>module http_2xx</strong> which works fine but <strong>not all services return 200 on /</strong>. hence i get status codes 404, 502 etc from some of the services. Any recommendation on how i could monitor the health of the ingress in our cluster using the blackbox exporter? any help is appreciated</p>
