feat(otel): add OpenTelemetry instrumentation for core memory operations by henrikrexed · Pull Request #2207 · MemTensor/MemOS

henrikrexed · 2026-08-04T10:45:05Z

Summary

Adds first-class OpenTelemetry instrumentation to MemOS conforming to memory-semconv v0.1.0, so MemOS emits uniform, benchmark-grade telemetry — spans, metrics, and logs — on the core memory operations. It is opt-in (a no-op unless OTEL_EXPORTER_OTLP_ENDPOINT is set) and every optional dependency is imported defensively, so default installs and local runs are unaffected.

What's instrumented

Traces — spans on memory.add / memory.search / memory.update / memory.delete:

memory.tier — L1/L2/L3 mapped to textual / activation / parametric (+ preference)
memory.operation, memory.user.id, memory.cube.id, memory.session.id, memory.item.count, memory.result.count, memory.query.text (search), memory.latency.ms

Metrics — memory.operations (counter), memory.operation.duration (ms histogram), memory.result.count (histogram), labeled by memory.operation + memory.tier.

Logs — structured, span-correlated records on each operation.

Propagation — W3C TraceContext installed globally; both the REST (FastAPI) and MCP entry-points bootstrap the SDK from env and extract inbound traceparent, so memory.* spans nest under a calling agent's trace end-to-end.

Changes

src/memos/telemetry.py — new instrumentation module (providers, semconv constants, span/metric/log helpers, configure_from_env bootstrap, W3C propagation).
src/memos/mem_os/core.py — instrument core add/search/update/delete.
src/memos/multi_mem_cube/single_cube.py — instrument the product-API add/search path.
src/memos/api/server_api.py — bootstrap OTel + FastAPIInstrumentor.
src/memos/api/mcp_serve.py — bootstrap OTel on the MCP server entry-point (otherwise MCP-served MemOS exports nothing).
pyproject.toml — new [otel] optional-dependency extra.
tests/ — telemetry + MCP-bootstrap regression tests (13 passing).

Validation

Validated end-to-end against a live OTel Collector → Tempo and Dynatrace: one connected trace CrewAI agent → LLM (Ollama) → MCP → memos (single trace_id), memory.tier=textual semconv spans, and memory_* metrics on service.name=memos. Both backends agree. Unit tests: pytest tests/test_telemetry.py tests/test_mcp_serve_telemetry.py → 13 passed.

Notes

Install with pip install "MemoryOS[otel]". Optional auto-instrumentation (opentelemetry-instrumentation-mcp) is imported defensively and disabled if absent.
Apache-2.0; no CLA/DCO required.

Instrument the core add / search / update / delete memory operations with OpenTelemetry spans, metrics, and logs, following the memory-semconv conventions. The L1/L2/L3 memory tiers are mapped onto the `memory.tier` attribute. - New `memos.telemetry` module: lightweight helpers that emit spans/metrics and degrade to no-ops when OpenTelemetry is not installed or configured, so there is zero runtime cost for users who do not opt in. - The application remains responsible for configuring the OTel SDK/exporters; this change only instruments the library (correct library/app separation). - Metrics cover data stored/indexed/utilized, per-tier utilization, query result/hit counts, and search latency. The search query is captured as a span attribute with cardinality/PII in mind. - Adds optional `opentelemetry-*` dependencies under an extra in pyproject. - Adds tests/test_telemetry.py (all green without an OTel backend present).

…port, product-API metrics Extends the core memory-semconv instrumentation so the telemetry is actually exported on every entry-point MemOS runs behind, and validated end-to-end. - telemetry.py: env bootstrap (configure_from_env), W3C TraceContext propagation, metrics (memory.operations, memory.operation.duration, memory.result.count) and span-correlated logs, alongside the add/search/update/delete spans. - api/server_api.py: bootstrap the OTel SDK from env + FastAPIInstrumentor so the REST entry-point emits server spans and propagates traceparent. - api/mcp_serve.py: bootstrap OTel in MOSMCPServer.__init__ so the MCP entry-point exports the memory.* telemetry too (otherwise it runs against the no-op provider and emits nothing over MCP); best-effort server-side MCP context extraction. - multi_mem_cube/single_cube.py: instrument the product-API add/search path. - pyproject.toml: opentelemetry-instrumentation-fastapi in the [otel] extra. - tests: telemetry + MCP-bootstrap regression guards (13 passing). All signals validated against a live OTel collector → Tempo + Dynatrace: memory.tier semconv spans + memory_* metrics on service.name=memos, connected end-to-end under an agent trace.

Base: main
Head: feat/memory-semconv-otel

🔍 OpenCodeReview found 13 issue(s) in this PR.

1. `pyproject.toml` (L74-L81)

The otel extra group uses unbounded upper-version constraints (e.g. >=1.27.0) while all other optional groups in this project enforce an upper bound (e.g. neo4j (>=5.28.1,<6.0.0)). OpenTelemetry follows semantic versioning but has historically introduced breaking changes across minor versions (especially for the SDK and exporters). Without an upper cap, a future opentelemetry-sdk 2.0.0 could silently break the instrumentation layer at install time. Consider adding a <2.0.0 ceiling to all six packages to align with the project's pinning strategy.

💡 Suggested Change

Before:

otel = [
    "opentelemetry-api (>=1.27.0)",
    "opentelemetry-sdk (>=1.27.0)",
    "opentelemetry-exporter-otlp-proto-grpc (>=1.27.0)",
    "opentelemetry-exporter-otlp-proto-http (>=1.27.0)",
    "opentelemetry-semantic-conventions (>=0.48b0)",
    "opentelemetry-instrumentation-fastapi (>=0.48b0)",
]

After:

otel = [
    "opentelemetry-api (>=1.27.0,<2.0.0)",
    "opentelemetry-sdk (>=1.27.0,<2.0.0)",

    "opentelemetry-semantic-conventions (>=0.48b0,<1.0.0)",
    "opentelemetry-instrumentation-fastapi (>=0.48b0,<1.0.0)",
]

2. `pyproject.toml` (L75-L80)

The same six OTel packages are duplicated verbatim in the all group instead of referencing the otel extra (e.g. MemoryOS[otel]). This creates a maintenance burden: version bumps must be applied in two places and it is easy for the two copies to drift out of sync. The all group should reference the otel extra by name, just as tree-mem, mem-scheduler, etc. would be referenced.

💡 Suggested Change

Before:

    "opentelemetry-api (>=1.27.0)",

After:

    "MemoryOS[otel]",

3. `pyproject.toml` (L78-L79)

opentelemetry-exporter-otlp-proto-http is declared as a dependency but telemetry.py only imports from opentelemetry.exporter.otlp.proto.grpc.* (gRPC exporters). The HTTP exporter is never imported or used in the current codebase. Including an unused package increases install size and may cause confusion. Remove it unless HTTP export support is planned in the near term.

4. `src/memos/api/mcp_serve.py` (L51-L63)

The try/except ImportError block covers both the import statement and the MCPInstrumentor().instrument() call. If instrument() raises an ImportError due to a missing transitive dependency, it will be silently swallowed and incorrectly logged as "package not installed", masking a real instrumentation failure that is distinct from the package being absent.

Separate the import guard from the instrumentation call so each failure is handled and reported correctly.

💡 Suggested Change

Before:

        try:
            from opentelemetry.instrumentation.mcp import MCPInstrumentor

            MCPInstrumentor().instrument()
            logger.info(
                "[MCP_SERVE] MCP instrumentation active — trace context propagates over MCP"

                "Install it (client + server) for end-to-end cross-service traces."
            )

After:

                    "[MCP_SERVE] MCPInstrumentor().instrument() failed: %s", exc
                )

5. `src/memos/api/mcp_serve.py` (L181-L182)

_bootstrap_telemetry() is called unconditionally in __init__, so every MOSMCPServer instantiation re-runs it. While configure_from_env() → configure() is idempotent (guarded by _initialized), the MCPInstrumentor().instrument() call inside _bootstrap_telemetry() is NOT guarded and will execute again on every construction when OTEL_EXPORTER_OTLP_ENDPOINT is set. Repeated calls to instrument() can cause duplicate spans or errors from the OTel auto-instrumentation library.

Guard the bootstrap with a module-level flag so it runs at most once per process.

💡 Suggested Change

Before:

        _bootstrap_telemetry()
        self.mcp = FastMCP("MOS Memory System")

After:

_bootstrap_telemetry_done = False

def _bootstrap_telemetry() -> None:
    global _bootstrap_telemetry_done
    if _bootstrap_telemetry_done:
        return
    _bootstrap_telemetry_done = True
    # ... rest of function unchanged

# In MOSMCPServer.__init__:
        _bootstrap_telemetry()
        self.mcp = FastMCP("MOS Memory System")

6. `src/memos/api/server_api.py` (L83-L84)

_FastAPIInstrumentor.instrument_app(app) is called whenever the opentelemetry-instrumentation-fastapi package is installed, even when configure_from_env() returned False (i.e., no OTLP endpoint was configured). In that case the instrumentor binds to the global no-op TracerProvider, which means every request still pays the overhead of span creation and context propagation — yet nothing is exported. The intent expressed in the surrounding comments is that instrumentation should only be active when the SDK is actually configured.

Fix: guard the instrumentation call on both conditions.

if _OTEL_FASTAPI_AVAILABLE and _OTEL_CONFIGURED:
    _FastAPIInstrumentor.instrument_app(app)

💡 Suggested Change

Before:

if _OTEL_FASTAPI_AVAILABLE:
    _FastAPIInstrumentor.instrument_app(app)

After:

if _OTEL_FASTAPI_AVAILABLE and _OTEL_CONFIGURED:
    _FastAPIInstrumentor.instrument_app(app)

7. `src/memos/mem_os/core.py` (L670-L675)

Bug: search_preference_memory passes self.session_id (the instance-level default) instead of target_session_id (the resolved value computed at the top of search). When a caller passes an explicit session_id argument, preference memory will be searched with the wrong session, causing cross-session data leakage or silent miss.

Change self.session_id → target_session_id.

💡 Suggested Change

Before:

                        memories = cube.pref_mem.search(
                            query,
                            top_k=top_k if top_k else self.config.top_k,
                            info={
                                "user_id": target_user_id,
                                "session_id": self.session_id,

After:

                        memories = cube.pref_mem.search(
                            query,
                            top_k=top_k if top_k else self.config.top_k,
                            info={
                                "user_id": target_user_id,
                                "session_id": target_session_id,

8. `src/memos/mem_os/core.py` (L590)

The span attribute uses is not None to record the effective top_k, but the inner search functions use a plain truthiness check (top_k if top_k else self.config.top_k). When a caller passes top_k=0, the span records 0 while the actual search silently uses self.config.top_k, making the telemetry data misleading and the top_k=0 path untestable via traces.

Align the span attribute with the actual runtime behaviour by using the same truthiness check, or — better — fix both call sites to use is not None consistently:

effective_top_k = top_k if top_k is not None else self.config.top_k

then reference effective_top_k in _span_attrs and pass it into both search functions.

💡 Suggested Change

Before:

            MEMORY_TOP_K: top_k if top_k is not None else self.config.top_k,

After:

            effective_top_k = top_k if top_k is not None else self.config.top_k
            # … then use effective_top_k in _span_attrs and in both search closures
            MEMORY_TOP_K: effective_top_k,

9. `src/memos/telemetry.py` (L94)

_item_count_gauge is declared and initialised to None but is never assigned in configure() and never referenced anywhere in this file. It is dead code that will mislead readers into thinking observable gauge / index-size reporting is implemented when it is not. Either implement it or remove the declaration.

10. `src/memos/telemetry.py` (L174-L179)

_initialized is only set to True at the very end of configure(). If any line before it raises (e.g. a network error during OTLPLogExporter construction, or any future expansion), the function returns with _initialized = False while the tracer provider, meter provider, and possibly the logging handler are already installed globally. A subsequent call would then reinstall another LoggingHandler on the memos root logger, causing every log record to be exported twice.

Fix: set _initialized = True immediately after the guard checks (before touching any global state), or wrap the body in a try/except that rolls back / cleans up on failure.

💡 Suggested Change

Before:

    otel_handler = LoggingHandler(level=logging.DEBUG, logger_provider=logger_provider)
    root_logger = logging.getLogger("memos")
    root_logger.addHandler(otel_handler)
    _otel_logger = logging.getLogger(f"{INSTRUMENT_NAME}.ops")

    _initialized = True

After:

    _initialized = True   # Mark before mutating globals; prevents double-init on partial failure

    otel_handler = LoggingHandler(level=logging.DEBUG, logger_provider=logger_provider)
    root_logger = logging.getLogger("memos")
    root_logger.addHandler(otel_handler)
    _otel_logger = logging.getLogger(f"{INSTRUMENT_NAME}.ops")

11. `tests/test_mcp_serve_telemetry.py` (L165-L170)

This test mutates the process-global OTel TracerProvider via trace.set_tracer_provider(provider) but never restores it. Any test that runs afterward and relies on the default no-op provider (or checks that _initialized is False) will silently inherit this SDK provider, making the suite order-dependent and potentially flaky in CI.

Restore the global state after the test, for example by saving the previous provider and resetting it, or by using a monkeypatch/fixture teardown:

prev_provider = trace.get_tracer_provider()
trace.set_tracer_provider(provider)
try:
    ...
finally:
    trace.set_tracer_provider(prev_provider)

Alternatively, use pytest's monkeypatch.setattr to scope the replacement to the test lifetime:

monkeypatch.setattr(trace, '_TRACER_PROVIDER', provider, raising=False)

12. `tests/test_telemetry.py` (L35-L41)

telemetry.py declares a fourth metric instrument at module level — _item_count_gauge: metrics.ObservableGauge | None = None — that this fixture never resets. If any test creates it (or the real configure() is invoked), its value leaks into subsequent tests. Add tel._item_count_gauge = None to keep the reset complete.

💡 Suggested Change

Before:

    tel._initialized = False
    tel._tracer = None
    tel._meter = None
    tel._otel_logger = None
    tel._op_counter = None
    tel._latency_histogram = None
    tel._result_count_histogram = None

After:

    tel._initialized = False
    tel._tracer = None
    tel._meter = None
    tel._otel_logger = None
    tel._op_counter = None
    tel._latency_histogram = None
    tel._item_count_gauge = None
    tel._result_count_histogram = None

13. `tests/test_telemetry.py` (L49-L58)

trace.set_tracer_provider() and metrics.set_meter_provider() mutate the process-wide OTel globals, but the fixture never tears them down or restores the previous providers. This causes cross-test and cross-module state pollution — in particular, tests/test_mcp_serve_telemetry.py::test_memory_span_service_name_is_memos also calls trace.set_tracer_provider() with a different provider, and whichever test runs last leaves a stale global for anything that follows.

Capture the old providers before overwriting, and restore them (plus call shutdown()) in teardown:

old_tracer_provider = trace.get_tracer_provider()
old_meter_provider = metrics.get_meter_provider()
# ... setup ...
yield span_exporter, metric_reader
tracer_provider.shutdown()
meter_provider.shutdown()
trace.set_tracer_provider(old_tracer_provider)
metrics.set_meter_provider(old_meter_provider)

💡 Suggested Change

Before:

    span_exporter = InMemorySpanExporter()
    tracer_provider = TracerProvider()
    tracer_provider.add_span_processor(SimpleSpanProcessor(span_exporter))
    trace.set_tracer_provider(tracer_provider)
    tel._tracer = tracer_provider.get_tracer(tel.INSTRUMENT_NAME)

    metric_reader = InMemoryMetricReader()
    meter_provider = MeterProvider(metric_readers=[metric_reader])
    metrics.set_meter_provider(meter_provider)
    tel._meter = meter_provider.get_meter(tel.INSTRUMENT_NAME)

After:

    old_tracer_provider = trace.get_tracer_provider()
    old_meter_provider = metrics.get_meter_provider()

All tests passed (6/6 executed). memos_python_core/changed-repo-python: 6/6. Duration: 1s [advisory, non-gating] AI-generated tests on branch test/auto-gen-dac9d2f6ee0314fb-20260804185426: 181/184 passed, 3 failed — these do NOT affect the PR verdict; review the branch manually.

…mport, lint, test guards Resolves the Copilot review comments on the upstream PR: - telemetry.py: guard the opentelemetry imports so `import memos.telemetry` (and thus `import memos.mem_os.core`) works on a default install WITHOUT the [otel] extra — the instrumentation degrades to a no-op (`_OTEL_AVAILABLE`, `_NoopSpan`, guarded configure/configure_from_env/get_tracer/memory_span). Drops the unused `get_logger_provider` import; moves `Callable` into a TYPE_CHECKING block; simplifies `_resolve_service_version` (no blind except). - core.py: drop unused telemetry constants (MEMORY_CUBE_ID, MEMORY_ITEM_COUNT, TIER_ACTIVATION, TIER_PARAMETRIC) — F401. - tests: guard both suites with `pytest.importorskip("opentelemetry")` and drop unused sys/types imports. The env bootstrap the reviewer asked for (configure_from_env + FastAPI/MCP entry-point wiring) is included in this branch (server_api.py / mcp_serve.py). Verified: 13 tests pass; `import memos.telemetry` succeeds with opentelemetry absent (no-op); ruff clean on telemetry.py.

Verified: no `src/memos` file has a tree.body top-level `opentelemetry` import (same AST walk check_dependencies uses); 13 tests pass; telemetry.py ruff clean; get_current_span works with opentelemetry present (real span) and absent (no-op).

No behavior change. Verified with ruff 0.11.8 + repo config: `ruff check` and `ruff format --check` both clean on all changed files; `check_dependencies.py` finds no top-level optional imports; 13 telemetry tests pass.

All tests passed (13/13 executed). memos_python_core/changed-repo-python: 13/13. Duration: 1s [advisory, non-gating] AI-generated tests on branch test/auto-gen-6bfc3a89d17f9cb9-20260804194123: 135/139 passed, 4 failed — these do NOT affect the PR verdict; review the branch manually.

Branch: feat/memory-semconv-otel

…[all] Root cause of the failing `Python tests` workflow: the PR added the `[otel]` optional-dependency extra to pyproject.toml but never regenerated poetry.lock, so `poetry check --lock` failed ("pyproject.toml changed significantly since poetry.lock was last generated") and CI's strict `poetry install` (poetry 2.1.3) errored before any test ran. - poetry.lock: regenerated — now includes opentelemetry-* and transitive deps (poetry check --lock passes). - pyproject.toml: add the opentelemetry packages to the `[all]` extra (they were the only sub-extra missing from `all`). CI's pytest step runs `poetry install --extras all`, so this makes opentelemetry present during the suite → the telemetry tests actually run (instead of pytest.importorskip skipping them) and cover telemetry.py, keeping total coverage above --cov-fail-under=28.
