From bf5fd17436c67adbcada9965d41fb84adf3baf1b Mon Sep 17 00:00:00 2001 From: Alberto Vara Date: Tue, 31 Oct 2023 17:44:44 +0100 Subject: [PATCH] feat(iast): include as iast telemetry metrics tags in the root span of the trace (#7354) For metrics that need to be correlated to traces, a small subset of IAST telemetry metrics can be included as tags in the root span of the trace following the next algorithm, this PR contains: - `iast_metrics` into asm_request_context - Span metrics with IAST `request.tainted` and `executed.skins.*` data TODO: add integration tests with a flask server and retrieve telemetry events from test agent but we need to refactor telemetry tests and move testagent fixture from conftest to a upper level conftest ## Checklist - [x] Change(s) are motivated and described in the PR description. - [x] Testing strategy is described if automated tests are not included in the PR. - [x] Risk is outlined (performance impact, potential for breakage, maintainability, etc). - [x] Change is maintainable (easy to change, telemetry, documentation). - [x] [Library release note guidelines](https://ddtrace.readthedocs.io/en/stable/releasenotes.html) are followed. If no release note is required, add label `changelog/no-changelog`. - [x] Documentation is included (in-code, generated user docs, [public corp docs](https://github.com/DataDog/documentation/)). - [x] Backport labels are set (if [applicable](https://ddtrace.readthedocs.io/en/latest/contributing.html#backporting)) ## Reviewer Checklist - [x] Title is accurate. - [x] No unnecessary changes are introduced. - [x] Description motivates each change. - [x] Avoids breaking [API](https://ddtrace.readthedocs.io/en/stable/versioning.html#interfaces) changes unless absolutely necessary. - [x] Testing strategy adequately addresses listed risk(s). - [x] Change is maintainable (easy to change, telemetry, documentation). - [x] Release note makes sense to a user of the library. - [x] Reviewer has explicitly acknowledged and discussed the performance implications of this PR as reported in the benchmarks PR comment. - [x] Backport labels are set in a manner that is consistent with the [release branch maintenance policy](https://ddtrace.readthedocs.io/en/latest/contributing.html#backporting) - [x] If this PR touches code that signs or publishes builds or packages, or handles credentials of any kind, I've requested a review from `@DataDog/security-design-and-guidance`. - [x] This PR doesn't touch any of that. --------- Co-authored-by: Christophe Papazian
