Ultimate Guide to Self-Hosted OpenTelemetry Monitoring with SSO (2026)

Table of Contents

The Community Spark #

A recurring pain point recently surfaced in the r/selfhosted community: “Any recommendations for a self-hosted OpenTelemetry monitoring tool which supports SSO?” As homelabs and self-hosted production environments mature, administrators are moving away from isolated dashboards toward unified observability pipelines. The catch? Modern teams require Single Sign-On (SSO) integration via OIDC/SAML to keep these dashboards secure behind their identity providers. Finding a tool that natively handles OpenTelemetry (OTel) while seamlessly integrating with Authentik, Authelia, or Keycloak is a critical requirement.

Synthesized Community Perspectives #

The community consensus is that while Prometheus remains the king of metrics, its native OpenTelemetry support can feel bolted-on rather than native. Users heavily debated the trade-offs between all-in-one platforms versus modular stacks.

The Grafana Stack (The Modular King): Many users pointed out that Grafana, combined with the OTel Collector and Tempo (for traces) and Loki (for logs), remains the most flexible solution. The community universally agreed that Grafana’s native SSO support (via OAuth2/OIDC) is enterprise-grade.
SigNoz (The OTel Purist): A vocal faction advocated for SigNoz. Because SigNoz is built specifically around OpenTelemetry and ClickHouse, it eliminates the need for multiple moving parts. Community members noted that while its SSO/SAML features are gated behind an enterprise license, OIDC authentication is available in the open-source edition.
The Uptrace Contention: A few users mentioned Uptrace for its lightweight footprint and native OTLP support. However, debates arose over its self-hosted SSO capabilities, which are restricted compared to Grafana.

Deep-Dive Actionable Guide: Configuring SigNoz with OIDC SSO #

Based on community successfully deployed setups, SigNoz offers the best turnkey OTel experience. Here is how to configure it with an OIDC provider (like Authentik or Keycloak).

Step 1: Deploy SigNoz via Docker #

git clone https://github.com/SigNoz/signoz.git
cd signoz/deploy/docker
docker compose up -d

Step 2: Configure OIDC in SigNoz #

To enable SSO, you need to modify the docker-compose.yaml file environment variables for the signoz and clickhouse services to pass authentication queries. Ensure your Identity Provider (IdP) is configured with a redirect URI of http://<your-signoz-domain>/api/v1/oidc/callback.

Update the query-service environment variables:

services:
  query-service:
    environment:
      - SIGNOZ_OIDC_ISSUER=http://<your-idp-domain>/realms/master
      - SIGNOZ_OIDC_CLIENT_ID=signoz
      - SIGNOZ_OIDC_CLIENT_SECRET=<your-secret-key>
      - SIGNOZ_OIDC_SCOPES=openid,email,profile

Restart the services: docker compose restart query-service.

Comparative Table: OTel Monitoring Tools #

Tool	Native OTel Support	SSO/OIDC Support (Self-Hosted)	Architecture Complexity	Best For
Grafana Stack	Good (via Promtail/Tempo)	Excellent (Built-in OAuth)	High (Multiple containers)	Modular setups & existing Grafana users
SigNoz	Excellent (Native OTLP)	Good (OIDC is OSS, SAML needs EE)	Medium (ClickHouse + 1 app)	OTel-first users wanting an all-in-one UI
Uptrace	Excellent (Native OTLP)	Limited (Requires reverse proxy hacks)	Low	Lightweight VPS monitoring

The Verdict / Expert Advice #

After synthesizing the community feedback and technical realities, the recommendation comes down to your architecture philosophy:

For the Homelabber / Hybrid Admin: Choose Grafana. If you already run Grafana for metrics, adding Tempo for traces via the OTel Collector is the least friction path. Its OIDC integration is rock-solid and fully open-source.
For the Enterprise Track / OTel Purist: Choose SigNoz. If you want a single UI built entirely around OpenTelemetry protocol (OTLP) without bolting on Prometheus agents, SigNoz handles massive trace volumes efficiently via ClickHouse, and its OSS OIDC support is sufficient for most self-hosted SSO needs.

Frequently Asked Questions (FAQ) #

Does Grafana support OpenTelemetry natively? Yes, Grafana supports OpenTelemetry through its native integrations with Tempo for distributed tracing and Prometheus for metrics, typically routed via the OpenTelemetry Collector.

Is SigNoz completely free for self-hosting with SSO? Yes, the open-source version of SigNoz supports OIDC for SSO. However, if your organization requires SAML integration, you will need to purchase their Enterprise license.

Can I use Authentik or Authelia for monitoring tool SSO? Both Authentik and Authelia are excellent choices for securing self-hosted monitoring tools. Authentik has superior native OIDC/SAML provider support that easily hooks into Grafana and SigNoz via standard OAuth2 environment variables.
