#23899 [Feat]: Add an AISIX AI Gateway Prometheus profile

Problem

Netdata's generic Prometheus collector can scrape AISIX, but it does not currently provide a named AISIX integration or curated charts for operating an AI gateway. Users would otherwise receive generic metric-family charts without an operator-oriented view of gateway traffic, latency, token usage, routing, policy enforcement, and telemetry health.

Description

I would like to contribute a stock aisix profile to the existing Prometheus collector for the open-source AISIX AI Gateway.

AISIX 1.2.0 exposes a dedicated Prometheus endpoint and a registered aisix_* metric catalog. The proposed profile would use the existing collector and automatic profile selection; it would not add a new collector, exporter, or runtime dependency.

Before preparing the full contribution, could you confirm that a product-specific AISIX stock profile and generated integration page are in scope?

Importance

nice to have

Value proposition

Gives Netdata users curated AI gateway views instead of generic metric-family charts.
Covers operational questions around request success, end-to-end latency and TTFT, token usage, routing and fallback, cache and guardrail outcomes, and exporter/configuration health.
Reuses AISIX's existing Prometheus endpoint and Netdata's generic collector, so no new collector is required.

Proposed implementation

If this direction is accepted, I would follow the repository's current stock-profile contract:

pin the source evidence to AISIX 1.2.0;
add an automatically selected aisix Prometheus profile;
define bounded chart identity and label handling for the public metric catalog;
add the required source semantics, profile design, proof bundle, and sanitized replay fixtures;
add Prometheus integration metadata so the generated documentation includes AISIX setup and metric coverage;
run the profile validator, proof replay, metadata generation, and relevant Go tests.
