28-68: Update test assertions to match new metric names withtrtllm_prefix.The test file
tests/unittest/llmapi/apps/_test_openai_prometheus.pycontains assertions that check for the old unprefixed metric names (lines 64-67), but your implementation now emits metrics with thetrtllm_prefix. These assertions will fail once the metric name changes are applied.Update the assertions to check for the prefixed names:
# Old (lines 64-67): assert "request_success_total" in data assert "e2e_request_latency_seconds" in data assert "time_to_first_token_seconds" in data assert "request_queue_time_seconds" in data # Should be updated to: assert "trtllm_request_success_total" in data assert "trtllm_e2e_request_latency_seconds" in data assert "trtllm_time_to_first_token_seconds" in data assert "trtllm_time_per_output_token_seconds" in data assert "trtllm_request_queue_time_seconds" in dataNote: The test is also missing an assertion for
time_per_output_token_seconds—add that as well.

17-17: LGTM! Consider making the prefix configurable.The metric prefix is correctly defined and consistently applied across all metrics. The hardcoded value is acceptable for the current use case.
If future flexibility is desired, the prefix could be made configurable via a constructor parameter:
- def __init__(self, labels: Dict[str, str]) -> None: + def __init__(self, labels: Dict[str, str], metric_prefix: str = "trtllm_") -> None: from prometheus_client import Counter, Histogram self.last_log_time = time.time() self.labels = labels - self.metric_prefix = "trtllm_" + self.metric_prefix = metric_prefix

**/*.py: Python code must target Python 3.8+.
Indent Python code with 4 spaces; do not use tabs.
Maintain module namespace when importing; prefer 'from package.subpackage import foo' then 'foo.SomeClass()' instead of importing the class directly.
Python filenames should be snake_case (e.g., some_file.py).
Python classes use PascalCase names.
Functions and methods use snake_case names.
Local variables use snake_case; prefix 'k' for variables that start with a number (e.g., k_99th_percentile).
Global variables use upper SNAKE_CASE prefixed with 'G' (e.g., G_MY_GLOBAL).
Constants use upper SNAKE_CASE (e.g., MY_CONSTANT).
Avoid shadowing variables from an outer scope.
Initialize all externally visible members of a class in the constructor.
Prefer docstrings for interfaces that may be used outside a file; comments for in-function or file-local interfaces.
Use Google-style docstrings for classes and functions (Sphinx-parsable).
Document attributes and variables inline so they render under the class/function docstring.
Avoid reflection when a simpler, explicit approach suffices (e.g., avoid dict(**locals()) patterns).
In try/except, catch the most specific exceptions possible.
For duck-typing try/except, keep the try body minimal and use else for the main logic.

Learning: For PR templates in TensorRT-LLM, avoid suggesting changes that would increase developer overhead, such as converting plain bullets to mandatory checkboxes. The team prefers guidance-style bullets that don't require explicit interaction to reduce friction in the PR creation process.
