Built natively on OpenTelemetry, it provides APM dashboards, distributed tracing with flamegraphs, log management with pipelines, custom metrics, alerting across all signals, and exception monitoring - all without vendor lock-in. SigNoz is available as a managed cloud service or self-hosted via Docker or Kubernetes. --- ## When to use this skill Trigger this skill when the user: - Wants to set up or configure SigNoz (cloud or self-hosted) - Needs to instrument an application to send traces, logs, or metrics to SigNoz - Asks about OpenTelemetry Collector configuration for SigNoz - Wants to create dashboards, panels, or visualizations in SigNoz - Needs to configure alerts (metric, log, trace, or anomaly-based) in SigNoz - Asks about SigNoz query builder syntax, aggregations, or filters - Wants to monitor exceptions or correlate traces with logs in SigNoz - Is migrating from Datadog, Grafana, New Relic, or ELK to SigNoz Do NOT trigger this skill for: - General observability concepts without SigNoz context (use the `observability` skill) - OpenTelemetry instrumentation not targeting SigNoz as the backend --- ## Setup & authentication ### SigNoz Cloud Sign up at `https://signoz.io/teams/` to get a cloud instance. You will receive: - A **region endpoint** (e.g. `ingest.us.signoz.cloud:443`) - A **SIGNOZ_INGESTION_KEY** for authenticating data ### Self-hosted deployment ```bash # Docker Standalone (quickest for local/dev) git clone -b main https://github.com/SigNoz/signoz.git && cd signoz/deploy/ docker compose -f docker/clickhouse-setup/docker-compose.yaml up -d # Kubernetes via Helm helm repo add signoz https://charts.signoz.io helm install my-release signoz/signoz ``` Self-hosted supports Docker Standalone, Docker Swarm, Kubernetes (AWS/GCP/Azure/ DigitalOcean/OpenShift), and native Linux installation. ### Environment variables ```env # For cloud - set these in your OTel Collector or SDK exporter config SIGNOZ_INGESTION_KEY=your-ingestion-key OTEL_EXPORTER_OTLP_ENDPOINT=https://ingest.<region>.signoz.cloud:443 OTEL_EXPORTER_OTLP_HEADERS=signoz-ingestion-key=<your-ingestion-key> ``` --- ## Core concepts SigNoz uses **OpenTelemetry** as its sole data ingestion layer. All telemetry (traces, metrics, logs) flows through an **OTel Collector** which receives data via OTLP (gRPC on port 4317, HTTP on 4318), processes it with batching and resource detection, and exports it to SigNoz's **ClickHouse** storage backend. The data model has three pillars: - **Traces** - Distributed request flows visualized as flamegraphs and Gantt charts. Each trace contains spans with attributes, events, and status codes. - **Metrics** - Time-series data from application instrumentation (p99 latency, error rates, Apdex) and infrastructure (CPU, memory, disk, network via hostmetrics receiver). - **Logs** - Structured log records ingested via OTel SDKs, FluentBit, Logstash, or file-based collection. Processed through log pipelines for parsing and enrichment. All three signals correlate - traces link to logs via trace IDs, and exceptions embed in spans. The **Query Builder** provides a unified interface for filtering, aggregating, and visualizing across all signal types. --- ## Common tasks ### Instrument a Node.js app ```bash npm install @opentelemetry/api @opentelemetry/sdk-node @opentelemetry/auto-instrumentations-node @opentelemetry/exporter-trace-otlp-grpc ``` ```javascript const { NodeSDK } = require("@opentelemetry/sdk-node"); const { getNodeAutoInstrumentations } = require("@opentelemetry/auto-instrumentations-node"); const { OTLPTraceExporter } = require("@opentelemetry/exporter-trace-otlp-grpc"); const sdk = new NodeSDK({ traceExporter: new OTLPTraceExporter({ url: process.env.OTEL_EXPORTER_OTLP_ENDPOINT || "http://localhost:4317", }), instrumentations: [getNodeAutoInstrumentations()], }); sdk.start(); ``` > Supported languages: Java, Python, Go, .NET, Ruby, PHP, Rust, Elixir, C++, Deno, > Swift, plus mobile (React Native, Android, iOS, Flutter) and frontend. ### Configure the OTel Collector for SigNoz ```yaml receivers: otlp: protocols: grpc: endpoint: 0.0.0.0:4317 http: endpoint: 0.0.0.0:4318 hostmetrics: collection_interval: 60s scrapers: cpu: {} memory: {} disk: {} load: {} network: {} filesystem: {} processors: batch: send_batch_size: 1000 timeout: 10s resourcedetection: detectors: [env, system] system: hostname_sources: [os] exporters: otlp: endpoint: "ingest.<region>.signoz.cloud:443" tls: insecure: false headers: signoz-ingestion-key: "${SIGNOZ_INGESTION_KEY}" service: pipelines: traces: receivers: [otlp] processors: [batch, resourcedetection] exporters: [otlp] metrics: receivers: [otlp, hostmetrics] processors: [batch, resourcedetection] exporters: [otlp] logs: receivers: [otlp] processors: [batch, resourcedetection] exporters: [otlp] ``` > For self-hosted, replace the endpoint with your SigNoz instance URL and remove > the `headers` section. ### Send logs to SigNoz Three approaches: 1. **OTel SDK** - Instrument application code directly with OpenTelemetry logging SDK 2. **File-based** - Use FluentBit or Logstash to tail log files and forward via OTLP 3. **Stdout/collector** - Pipe container stdout to the OTel Collector's filelog receiver ```yaml # FluentBit output to SigNoz via OTLP [OUTPUT] Name opentelemetry Match * Host ingest.<region>.signoz.cloud Port 443 Header signoz-ingestion-key <your-key> Tls On Tls.verify On ``` > Log pipelines in SigNoz can parse, transform, enrich, drop unwanted logs, and > scrub PII before storage. ### Create dashboards and panels Navigate to **Dashboards > New Dashboard**. Add panels using the Query Builder: 1. Select signal type (metrics, logs, or traces) 2. Add filters (e.g. `service.name = my-app`) 3. Choose aggregation (Count, Avg, P99, Rate, etc.) 4. Group by attributes (e.g. `method`, `status_code`) 5. Set visualization type (time series, bar, pie chart, table) Use `{{attributeName}}` in legend format for dynamic labels. Multiple queries can be combined with mathematical functions (log, sqrt, exp, time shift). > SigNoz provides pre-built dashboard JSON templates on GitHub that can be imported. ### Configure alerts SigNoz supports six alert types: - **Metrics-based** - threshold on any metric - **Log-based** - patterns, counts, or attribute values - **Trace-based** - latency or error rate thresholds - **Anomaly-based** - automatic anomaly detection - **Exceptions-based** - exception count or type thresholds - **Apdex alerts** - application performance index Notification channels include Slack, PagerDuty, email, and webhooks. Alerts support routing policies and planned maintenance windows. A Terraform provider is available for infrastructure-as-code alert management. ### Monitor exceptions Exceptions are auto-recorded for Python, Java, Ruby, and JavaScript. For other languages, record manually: ```python from opentelemetry import trace tracer = trace.get_tracer(__name__) with tracer.start_as_current_span("operation") as span: try: risky_operation() except Exception as ex: span.record_exception(ex) span.set_status(trace.StatusCode.ERROR, str(ex)) raise ``` Exceptions group by service name, type, and message. Enable `low_cardinal_exception_grouping` in the clickhousetraces exporter to group only by service and type (reduces high cardinality from dynamic messages). ### Query with the Query Builder ``` # Filter: service.name = demo-app AND severity_text = ERROR # Aggregation: Count # Group by: status_code # Aggregate every: 60s # Order by: timestamp DESC # Limit: 100 ``` Supported aggregations: Count, Count Distinct, Sum, Avg, Min, Max, P05-P99, Rate, Rate Sum, Rate Avg, Rate Min, Rate Max. Filters use `=`, `!=`, `IN`, `NOT_IN` operators combined with AND logic. Advanced functions: EWMA smoothing (3/5/7 periods), time shift comparison, cut-off min/max thresholds, and chained function application. --- ## Error handling | Error | Cause | Resolution | |---|---|---| | No data in SigNoz after setup | OTel Collector not reaching SigNoz endpoint | Add a `debug` exporter to the collector config to verify telemetry is received locally; check endpoint URL and ingestion key | | Port 4317/4318 already in use | Another process bound to OTLP ports | Stop conflicting process or change collector receiver ports | | `context deadline exceeded` | Network/firewall blocking gRPC to SigNoz cloud | Verify outbound 443 is open; check TLS settings in exporter config | | High cardinality exceptions | Dynamic exception messages creating too many groups | Enable `low_cardinal_exception_grouping` in clickhousetraces exporter | | Missing host metrics | hostmetrics receiver not configured or Docker volume not mounted | Add hostmetrics receiver with scrapers; set `root_path: /hostfs` for Docker deployments | --- ## References For detailed content on specific sub-domains, read the relevant file from the `references/` folder: - `references/instrumentation.md` - Language-specific instrumentation guides and setup patterns (read when instrumenting a specific language) - `references/otel-collector.md` - Advanced OTel Collector configuration, receivers, processors, and exporters (read when customizing the collector pipeline) - `references/query-builder.md` - Full query builder syntax, aggregation functions, and advanced analysis features (read when building complex queries or dashboards) Only load a references file if the current task requires it - they are long and will consume context. --- ## Related skills > When this skill is activated, check if the following companion skills are installed. > For any that are missing, mention them to the user and offer to install before proceeding > with the task.
