Backport of #62432 to release/10.0-rc1
/cc @sebastienros @Elanis
Empty "http.route" tags should be set to "/"
Normalizes empty routes to
/when used telemetry for thehttp.routetag.Description
Currently an empty route and
/are seen as two values for telemetry purposes. This PR uses/as the common value used in telemetry as they represent the same thing.Fixes #62431
Customer Impact
Wrong telemetry reported.
Some diagnostic tooling isn't happy with an empty string route value. Also, the meaning of an empty string route isn't immediately obvious. Using
/instead of empty string makes it clear that this route is for the root of the web app.Regression?
[If yes, specify the version the behavior has regressed from]
Risk
It's only changing a empty tag to
/to aggregate metrics correctly.Verification
Packaging changes reviewed?
