Adding Moesif Tracer Module - #421
Conversation
📝 WalkthroughWalkthroughAdds the Moesif tracing adapter API, authenticated search client, OpenTelemetry Collector routing, Helm resources, container packaging, and installation documentation. ChangesMoesif tracing module
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟠 High · up to This PR adds a new tracing adapter and deployment, but the current head can start without required search tokens and then return 500s, expose response payloads in logs, route traffic to unhealthy pods, and fail its build lint checks. These create concrete correctness, privacy, availability, and release-readiness risks, so the PR is not ready to merge until addressed. Sequence Diagram(s)sequenceDiagram

config-loading function containing oauthClientSecret to require
OAUTH_CLIENT_SECRET from the environment, removing its hardcoded fallback;
preserve the existing client ID default, and ensure missing or empty secrets
propagate as unset so the startup guard in main rejects the configuration.
- Line 39: Update LoadConfig’s SEARCH_AUTH_MODE handling to validate the value
against the supported authentication modes (api_key and bearer) and reject
unknown values during startup. Preserve the existing default mode and ensure
invalid configuration returns the established configuration error path before
the search client is used.
In `@observability-tracing-moesif/adaptor-api/internal/envresolver/resolver.go`:
- Line 65: The environment-loading request in the resolver must not hardcode the
"default" namespace. Update the surrounding resolver flow and its callers to
obtain the requested namespace from TracesQueryRequest.searchScope.namespace, or
otherwise load and retain environment mappings for every supported namespace, so
ResolveUID and Client.ResolveEnvToken work for non-default namespaces.
In `@observability-tracing-moesif/adaptor-api/internal/handler/handler.go`:
- Around line 392-397: Update the duration calculation in buildSearchRequest to
derive the trace end from span end times rather than the last span’s start time.
Aggregate the maximum response.time, or add each matching duration_ms to
request.time before taking the maximum, then compute durationNs from the
resulting start and end values.
- Around line 412-423: Update buildSearchRequest to add the proposed errorCount
filter aggregation for spans whose span.status is error, add an ErrorCount field
to TraceBucket so the response is decoded, and replace the constant hasErrors
assignment in the traceItem construction with bucket.ErrorCount.DocCount > 0.
- Around line 47-53: Update the missing-header validation blocks in handler.go,
including the duplicate blocks at lines 47-53, 102-108, and 163-169, to return
http.StatusBadRequest with gen.BadRequest instead of a 404/notFound response. In
observability-tracing-moesif/adaptor-api/api/observability-tracing-adapter-api.yaml
lines 212-231, update the contract only if the span-not-found path in handler.go
retains a 404: add notFound to the ErrorResponse.title enum and declare the
affected operation’s 404 response.
- Around line 159-192: Update the GetSpanDetailsForTrace endpoint contract to
require a search scope, then parse and validate that scope before constructing
search.TraceSearchParams. Apply the scope through applyScope so Namespace,
Project, Component, and Environment are included, and derive/pass the
environment token needed by SearchTraceSpanById instead of resolving an empty
key; preserve the existing authentication and not-found responses.
- Around line 67-70: Clamp the limit assigned in the handler’s
request-processing block to the documented range of 1–1000, including values
supplied through req.Limit, before it becomes the aggregation Size. Apply the
identical clamping logic in QuerySpansForTrace so both entry points enforce the
same bounds.
- Around line 339-342: Update the status mapping in the handler’s SpanStatus
construction to translate upstream values through a dedicated mapSpanStatusCode
helper. Normalize case, map “ok”/“status_code_ok” to gen.Ok and
“error”/“status_code_error” to gen.Error, and return gen.Unset for all other
values instead of passing raw strings to gen.SpanStatusCode.
In `@observability-tracing-moesif/adaptor-api/internal/search/client.go`:
- Around line 201-203: Update the search response logging in the request
handling paths around the existing response log statements to remove
responseBody from Info-level logs. Log only the status code, hit count, and took
values, applying the same change to all three occurrences; retain the response
body only in the existing error branch or behind Debug-level logging.
- Around line 468-520: Update buildSpansSearchRequest to include a sort clause
on request.time using params.SortOrder, while preserving the existing size and
filter construction. Ensure the generated request honors the caller’s resolved
sort direction for both ascending and descending requests.
In `@observability-tracing-moesif/adaptor-api/Makefile`:
- Around line 14-15: Update the Makefile build target to create the bin
directory before invoking go build, while preserving the existing
bin/adaptor-api output path.
In
`@observability-tracing-moesif/helm/templates/opentelemetry-collector/configMap.yaml`:
- Around line 25-36: Update the OpenTelemetry Collector pipeline configuration
so routing evaluates openchoreo.dev/environment before resource/cleanup removes
it: remove resource/cleanup from traces/in, add it after the routing connector
in every traces/{{ . }} pipeline, and configure the routing connector’s
default_pipelines to a valid fallback pipeline so unmatched traces are not
silently dropped.
In `@observability-tracing-moesif/module.yaml`:
- Around line 8-11: Align the image name configured by the module.yaml images
entry with the Helm chart’s moesif.adapter.image.repository value, and add the
missing Helm mapping field if needed. Ensure CI publishes the same repository
image that the chart installs.
In `@observability-tracing-moesif/README.md`:
- Around line 20-24: Update the README’s Moesif secret creation instructions to
avoid passing Collector Application IDs or bearer tokens through kubectl
arguments. Replace the --from-literal entries in the kubectl create secret
generic command with --from-file or another protected input method, and apply
the same change to the corresponding instructions around the additionally
referenced section.

where possible or explicit placeholder values for required settings. Add inline
comments identifying values that users must override, and ensure the keys match
the names consumed by the collector and adapter templates.
---
Minor comments:
In `@observability-tracing-moesif/adaptor-api/internal/envresolver/resolver.go`:
- Line 84: Update the response logging in the resolver flow around the
environments request to remove the full body from the Info-level log. Log the
response status and environments item count instead, while retaining the body
for the existing error path near the error handling.
In `@observability-tracing-moesif/adaptor-api/internal/handler/handler.go`:
- Around line 91-95: The handler currently sets Total from len(traces), which
only reflects the returned page. Update the trace query and response flow around
mapAggregationBucketsToTraces to obtain the total matching trace count using a
cardinality aggregation on trace_id.raw, then populate Total with that
aggregation result while preserving the existing returned traces and TookMs
values.
- Around line 30-41: Update Handler.Health to remove the upstream probe from
both JSON responses: return only status and error on HealthProbe failure, and
only status for unhealthy or healthy probe results, matching the declared
/healthz contract.
In `@observability-tracing-moesif/adaptor-api/internal/search/client.go`:
- Around line 195-198: Update the error handling around ResolveEnvToken in the
affected client methods, including the paths near the existing wrappers at lines
245 and 294, so unsupported environments return a distinct typed or sentinel
error instead of an “internal error.” Update the corresponding handler.go
mappings to translate that error to HTTP 400 while preserving HTTP 500 for
genuine adapter failures and keeping the client-facing detail meaningful.
In `@observability-tracing-moesif/adaptor-api/Makefile`:
- Around line 7-12: The generate target hardcodes the oapi-codegen binary path
as $(shell go env GOPATH)/bin/oapi-codegen, which does not respect the GOBIN
environment variable that go install honors in the oapi-codegen-install step.
Update the generate target to either use the GOBIN variable in the binary path
lookup (defaulting to GOPATH/bin if GOBIN is unset) or invoke the tool through
go run with the same version specification used in oapi-codegen-install,
ensuring CI workflows and custom GOBIN configurations work consistently.
In `@observability-tracing-moesif/helm/templates/adapter/deployment.yaml`:
- Around line 37-64: Update the moesif-search-secret volume in the adapter
Deployment to use .Values.moesif.adapter.searchSecretName instead of the
hardcoded moesif-trace-search-secret, while preserving the /etc/moesif/env
volumeMount. Mark the secret volume optional: true to match the optional
secretKeyRef entries.
In `@observability-tracing-moesif/README.md`:
- Around line 102-110: Update the README configuration documentation to
distinguish the two search credential secrets: document that the mounted
moesif-trace-search-secret at /etc/moesif/env serves the relevant authentication
mode, while moesif.adapter.searchSecretName (default moesif-search-credentials)
supplies SEARCH_API_KEY and SEARCH_BEARER_TOKEN for the other mode.
Alternatively, document how to configure the mounted secret name, ensuring both
authentication paths are unambiguous.
- Around line 156-161: Update the uninstall instructions in the README to also
delete the installation-created moesif-trace-search-secret, alongside
moesif-tracing-secret, so search bearer tokens are removed from the namespace;
if custom credential secrets are supported, document their separate cleanup as
well.

Nitpick comments:
In
`@observability-tracing-moesif/adaptor-api/api/observability-tracing-adapter-api.yaml`:
- Around line 280-285: Update the TracesQueryResponse schema: since no operation
references it, remove it; alternatively, retain it only if TracesListResponse,
TraceSpansListResponse, and TraceSpanDetailsResponse each require distinct
identifying properties (traces, spans, and spanId respectively) so the oneOf
branches are mutually exclusive.
- Around line 288-333: Declare maxItems: 1000 on the traces array in
TracesListResponse and apply the same maxItems constraint to the spans array in
TraceSpansListResponse, matching the documented and request limit cap.
In `@observability-tracing-moesif/adaptor-api/cmd/main.go`:
- Around line 44-52: Update the server setup around gin.Default and r.Run to use
Gin release mode with gin.New and gin.Recovery, then configure an http.Server
with explicit read-header, read, and write timeouts. Run the server
asynchronously, handle SIGINT and SIGTERM, and call srv.Shutdown with a bounded
context so in-flight requests can complete; ignore http.ErrServerClosed while
logging other listen failures.
In `@observability-tracing-moesif/adaptor-api/Dockerfile`:
- Around line 4-12: Update the builder and runtime image references in the
Dockerfile to approved patch-level versions with immutable digests, replacing
golang:1.25-alpine and alpine:latest. Obtain and apply the pinned references
through the project’s explicit dependency-update process while preserving the
existing build stages.
In `@observability-tracing-moesif/adaptor-api/go.mod`:
- Line 13: Regenerate Go module metadata using the existing tidy target so the
Gin and OAPI runtime dependencies used by the adapter are recorded as direct
dependencies. Commit the resulting updates to go.mod and go.sum, including both
affected dependency entries.
In `@observability-tracing-moesif/adaptor-api/internal/config/config.go`:
- Around line 72-91: Update loadEnvTokens to report token-directory and per-file
read failures instead of silently returning an empty or partial map, either by
returning an error through LoadConfig or by accepting a *slog.Logger. Also log
the number of successfully loaded environments while preserving the existing
token parsing behavior.
In `@observability-tracing-moesif/adaptor-api/internal/handler/handler.go`:
- Around line 240-243: Verify the real Moesif trace event payload and update
mapHitToSpanRecord’s field paths and extraction logic to match it, ensuring
missing or incorrect paths are handled explicitly rather than silently producing
empty spans. Replace the comment above spanRecord with documentation of the
confirmed payload structure, removing the unverified assumption and open
question.
- Around line 225-238: Update the OpenAPI item schemas for the spans and traces
arrays with x-go-type-name or named components so oapi-codegen emits a reusable
named type; regenerate the API types, remove the manually duplicated
traceSpanItem alias, and update its usages in the handler to reference the
generated type directly.
In `@observability-tracing-moesif/adaptor-api/internal/search/client.go`:
- Around line 150-156: Move the “HealthProbe calls…” documentation comment from
above AuthMode to directly above the HealthProbe method, and retain the existing
AuthMode comment above AuthMode so each exported method documents its own
behavior.
- Around line 385-414: Extract the duplicated namespace, project, component,
environment, trace ID, and span ID match_phrase construction from the search
request builders into a shared buildScopeFilters function. Update both callers,
including buildSearchRequest, to reuse it while preserving buildSearchRequest’s
separate trace_id.raw exists clause and existing filter behavior.
- Around line 355-362: Update the response-reading logic in the client method
containing io.ReadAll to wrap resp.Body with io.LimitReader and enforce the
established maximum response-size limit before reading. Preserve the existing
status-code return and wrapped read-error behavior, while ensuring oversized
upstream responses cannot be fully buffered.
- Around line 180-199: Extract the duplicated search-request flow from
SearchTraceEvents, SearchTraceSpans, and SearchTraceSpanById into one shared
helper that accepts the request body and operation label. Move path selection,
query construction, ResolveEnvToken, do, status validation, and response
unmarshalling into the helper, preserving each method’s request builder and log
message by passing the appropriate inputs.
In `@observability-tracing-moesif/helm/templates/adapter/deployment.yaml`:
- Around line 24-27: Add a container-level securityContext to the adapter
container with allowPrivilegeEscalation disabled, all Linux capabilities
dropped, and a read-only root filesystem, while retaining the existing pod-level
securityContext. Add livenessProbe and readinessProbe configurations using the
chart’s established health_check extension endpoint and matching collector probe
pattern, so unready or hung containers are excluded from traffic.

In `@observability-tracing-moesif/adaptor-api/cmd/main.go`:
- Around line 28-35: Replace the r.Run call in main with an explicit http.Server
configured with appropriate ReadTimeout, WriteTimeout, and IdleTimeout values,
and serve the Gin router through it. Add signal-aware graceful shutdown using
os/signal and syscall, canceling with a bounded time.Context and handling
non-shutdown server errors without abruptly terminating in-flight requests.
In `@observability-tracing-moesif/adaptor-api/internal/search/client.go`:
- Around line 133-137: Move the HealthProbe documentation so it directly
precedes the HealthProbe method, and keep the AuthMode documentation directly
above AuthMode in the Client type. Do not alter either method’s implementation.
- Around line 163-176: Extract the shared request flow from SearchTraceEvents,
SearchTraceSpans, and SearchTraceSpanById into one helper accepting the
marshalled request body and a log label. Move path/query construction, token
resolution, and status handling into that helper, then update all three methods
to delegate to it while preserving their distinct request builders and log
messages.
- Around line 368-397: Extract the duplicated six-clause scope filter
construction into a shared function that accepts TraceSearchParams and returns
the filter slice. Replace both filter-building sections, including the builders
around the existing clauses and their counterpart later in the file, with calls
to this function so future parameter fields are updated in one place.
