I have a weird problem. I’ve set up Blackbox probes for both HTTP and TCP targets, and they all show as “UP” in the Prometheus interface (see 2 examples below):
However, when I try to add them to Grafana, the HTTP probes show “UP”, but the TCP probes show “DOWN”.
My setups for those are in the first post.
Can anybody explain what’s wrong with the setup for the TCP target, since it shows “DOWN” in Grafana and not “UP” (like it does in the Prometheus interface)?
Thanks a lot!
