No info about hop address in MTR metric #49

Open arsbest opened 5 months ago

arsbest commented 5 months ago

I use network_exporer v1.7.6. For example try to probe mtr google.com. And i cant see in metric addresses of intermediate hops. If i correctly understand this info must be in path label

If I run local mtr google.com i can see host ip for each hop.

I'm also seeing this behavior with mtr targets. Something is preventing path from being stored for a number of hops, resulting in most data points being associated with unknown.

I've confirmed that running mtr to the same target manually from within the network_exporter container results in the expected hop values/ips. Wish I had more insight as to where exactly it might be encountering issues. Happy to set flags/logging etc if it would help narrow down! My data is pretty similar as well:
