[FR] Support `blackbox_exporter_probes` interface

[chanchiwai-ray]

Enhancement Proposal

Traefik K8s Operator is commonly deployed in environments / products (such Sunbeam) that need to route requests from the outside of a Kubernetes cluster to Juju units and applications . The traefik application contains all the URLs that it proxied, making it a good candidate for Charmed Blackbox Exporter to get the endpoints for probing without manually configuring the probe endpoints.

Impact

Medium (The feature may be helpful in the future)

Impact Rationale

By supporting blackbox_exporter_probes interface, we will be able to monitor SSL certificate and API related issues in sunbeam (or other products that depend on traefik). This is critical to a product’s operation readiness.

Hi @chanchiwai-ray

Do you think this could be applicable to all charmed ingresses? If you would like to see this implemented in the next cycle, i would request you to create a ticket for your need(s) on the product feedback board. We are currently working on our roadmap for next cycle, so we will consider all incoming requests from the feedback board.

Hi @swetha1654. I guess this could be for all charmed ingresses, but we don't have use case for other yet (traefik is used in sunbeam, and we have a use case for that).

This is currently put under the product feedback board under my team and your team: https://warthogs.atlassian.net/browse/PF-6504. For some reason, it's only showing in our team, but if you filter your team, you can still this card. The reason for us to put it under both teams is that we could have design and implment it if your team does not have bandwidth (with your team being the reviewer).
