🔌 Plugin overview

  • Plugin name: Jaeger
  • Purpose / problem solved: Monitor services, dependencies, operations, and traces from a Jaeger distributed tracing backend, via its Query API — an auto-discovered service map, a call-dependency graph with call counts, and per-service operation/trace drilldown with duration, kind, and status.
  • Primary audience: Platform teams / SREs / backend engineers running Jaeger for distributed tracing who want it visible alongside their other infrastructure in SquaredUp.
  • Authentication method(s): None — Jaeger's Query API has no built-in authentication. Hybrid plugin: supports both cloud mode (direct) and relay agent mode (for private/firewalled Jaeger deployments).

🧪 Testing

Tested end-to-end against a real deployed tenant, running against an actual on-prem Jaeger instance via the relay agent (not just structural validation).

  • Verified the services and dependencies streams directly via squaredup test against live data, including diagnosing and fixing a real indexing failure: the dependencies stream's original custom lookback parameter had no fallback, so when invoked by indexDefinitions/default.json (no dashboard tile context) it went out unbounded and timed out the connector. Switched dependencies over to the standard dashboard timeframe mechanism (matching traces) instead of a bespoke control, restricted to last1hourlast7days since the dependency-graph query is comparatively expensive, and added a safe fallback for the timeframe-less indexing context.
  • operations and traces verified directly against the live tenant.
  • Reviewed and fixed two real bugs in traces.js's OTLP decoding found during review: a duration-precision bug (rounding start/end to milliseconds independently before subtracting, rather than computing the duration in full nanosecond precision first) that could overstate short spans' duration by up to 1ms, and a SPAN_KIND default-value bug where proto3 JSON's omission of default-valued fields meant an INTERNAL/unspecified-kind span (very common) rendered as the literal string "undefined" instead of "UNSPECIFIED".
  • Confirmed (via Jaeger's own upstream test fixtures) that /api/v3/traces returns traceId/spanId as hex strings, not base64 — so no conversion was needed there, despite that being a real risk for a generic OTLP-JSON consumer.
  • Renamed source types (Jaeger Service/Jaeger DependencyService/Dependency) to follow the platform's non-prefixed source-type convention, propagated consistently across every referencing file in one pass.

⚠️ Known limitations

  • Dependencies' selectable timeframe is restricted to last 1 hour–last 7 days — the dependency-graph query is comparatively expensive on some storage backends, so it's deliberately narrower than Traces' full range.
  • Scheduled indexing of Dependencies always uses a 30 minute trailing window (imports run every 12 hours by default) since indexing has no dashboard timeframe context — a dependency that only occurred outside that trailing hour won't be indexed until it recurs. Correlation rules will remove this limitation in the near future.
  • Traces are per-service only — no cross-service trace search or single-trace detail view in this version.
  • No Service Performance Monitoring (SPM) metrics — SPM requires a separate metrics storage backend most Jaeger deployments don't enable.
  • No authentication — the Jaeger Query API has none; this plugin can't authenticate through a reverse proxy that requires it.
  • Dependency and Service objects aren't correlated (no edge between them) — a Dependency is really edge-shaped data (a call relationship), not a node, and the platform doesn't yet support importing data streams directly as graph edges. Revisit once that lands rather than forcing it through a same-plugin correlation rule now.
  • Read-only — the plugin never creates, modifies, or deletes anything in Jaeger.

📝 Walkthrough

Walkthrough

Jaeger v1 adds WebAPI connection settings, service and dependency indexing, operations and trace data streams, OTLP trace parsing, index definitions, scopes, dashboards, and setup documentation.

Changes

Jaeger v1 integration

Layer / File(s) Summary
Plugin contract and connection setup
plugins/Jaeger/v1/metadata.json, plugins/Jaeger/v1/ui.json, plugins/Jaeger/v1/configValidation.json, plugins/Jaeger/v1/custom_types.json, plugins/Jaeger/v1/indexDefinitions/default.json, plugins/Jaeger/v1/cspell.json, plugins/Jaeger/v1/docs/README.md
Defines Jaeger metadata, WebAPI connection fields, connection validation, Service and Dependency types, index mappings, spelling terms, and setup documentation.
Service and dependency streams
plugins/Jaeger/v1/dataStreams/services.json, plugins/Jaeger/v1/dataStreams/dependencies.json
Retrieves services from /api/v3/services and dependencies from /api/dependencies. The streams map service, parent, child, call count, and dependency label fields.
Operations and trace streams
plugins/Jaeger/v1/dataStreams/operations.json, plugins/Jaeger/v1/dataStreams/traces.json, plugins/Jaeger/v1/dataStreams/scripts/traces.js
Retrieves service operations and traces. The trace script converts OTLP JSON spans into flattened records with identifiers, timing, duration, status, service metadata, and attributes.
Scopes and dashboards
plugins/Jaeger/v1/defaultContent/scopes.json, plugins/Jaeger/v1/defaultContent/manifest.json, plugins/Jaeger/v1/defaultContent/overview.dash.json, plugins/Jaeger/v1/defaultContent/service.dash.json
Adds a single-service scope, overview and service dashboard entries, service and dependency visualizations, and service-scoped operations and traces tiles.

Mergeability Score: ⚪ Minimal · up to dfe66

The Jaeger dependency view has a localized formatting configuration issue, with digit grouping applied in the data stream rather than the dashboard column. This does not affect data correctness or availability, so the PR is merge-ready after normal review with that cleanup noted.
