What is the prometheus.yml scrape config.

N/A

I would like to see the logs produced by the probe on the stdout of the containers. --log.level=error, the log could be reduiced to a minimum.

This avoid the required to make the export web ui Accessable.

I am also interested in this feature :) Is there any plan to implement it or another option to get the logs into stdout?

jkroepke commented

@rei-ber PR is merged: #1091

rei-ber commented

Thanks for implementing :)
When do you deploy a new release, which contains this feature?

jkroepke commented

I'm not a maintainer here, maybe @electron0zero cam give us some details.

electron0zero commented

it will be in next release but we don't have timeline for next release, in the meantime you can use docker images built from master branch. we publish them here: https://quay.io/repository/prometheus/blackbox-exporter?tab=info

another option is build it from master and use that. building it is fairly easy, see https://github.com/prometheus/blackbox_exporter?tab=readme-ov-file#building-the-software for details.
