Instance shown as "up" although status code 403 (module http_2xx)

[svenmueller]

Hi,

I'm using the latest Docker image of blackbox for probing targets. I'm having a target probe (module http_2xx, config as in https://github.com/prometheus/blackbox_exporter/blob/master/blackbox.yml) where the server returns status code 403 (due to IP resctriction), but the target instance is still shown as "up".I would expect status "down" since i'm using the defaul config for module http_2xx which checks for status code 200-300.

When looking at the value of probe_http_status_code for this instance, it shows 403.

Any idea why the instance is still shown as "up"?

Cheers Sven

You're looking for the probe_success metric.

If we used up then you'd lose all the other metrics when a probe failed.
