Unable to Run k6 Tests on Private Probe for Local Kubernetes Cluster

[SeamusGrafana]

I have a Private SM Agent deployed on a private Kubernetes Cluster (either in GCP or with k3d), and I am trying to create a Synthetic Monitoring Check that uses that Private Probe (only) to run checks against applications in that Cluster.

However, the checks fails, due to restrictions, e.g.;

error	
Get "http://opentelemetry-demo-frontendproxy.mythical.svc.cluster.local:8080/api/products": hostname (opentelemetry-demo-frontendproxy.mythical.svc.cluster.local) is in a blocked pattern (*.cluster.local)

However, I have configured the --blocked-nets="" so this should allow any checks on any network.

If I remove the .cluster.local it then fails with;

Get "http://opentelemetry-demo-frontendproxy.mythical.svc:8080/api/products": IP (10.44.5.128) is in a blacklisted range (10.0.0.0/8)

This seems to happen for either of the MultiHTTP Checks or the Scripted Checks.

I am using the latest Tag for the SM Agent, and pulled it before running these tests.

I've confirmed this. There are a couple things causing this, one is a bug that #731 will solve, and the other is that, for multihttp in particular, this denylist is not configurable:

synthetic-monitoring-agent/internal/prober/multihttp/script.tmpl

Line 43 in 76926b4

blacklistIPs: ['10.0.0.0/8'],

I've played a bit with how making this customizable for multihttp, but that requires a bit more of work and I think should be prioritized.

This should be mostly solved in v0.24.3, except for the caveat mentioned in #735

Closing this one in favor of 735.
