# SigNoz
SigNoz is an open-source observability platform that unifies traces, metrics, and
logs in a single backend powered by ClickHouse. 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 |
