Push API alternative to Prometheus for small SaaS
The article advises beginners building a small SaaS custom metrics dashboard to prefer a push-style metrics API for app-level business measurements, while retaining Prometheus plus Grafana for Kubernetes, host monitoring, or where a richer infrastructure ecosystem is required. It explains the architectural differences between Prometheus's pull/scrape model and push APIs, highlights operational failure modes (duplication, staleness, delivery errors), and recommends starting by validating a single metric and the failure model before committing to a full stack. The author suggests running short bake-offs including Infrai (a REST-based option), Datadog, New Relic, Honeycomb, and emphasizes adding heartbeats and notification/deduplication components when needed.
- Recommendation: use a push-style metrics API for narrow, app-level custom metrics dashboards for beginners.
- Keep Prometheus plus Grafana for Kubernetes and host/ infrastructure monitoring where Prometheus's ecosystem and PromQL matter.
- Infrai is presented as a plain REST reporting and querying option; the article states the platform exposes "295 routes across 20 modules."

Structured Handoffs Reduce Repeat On-Call Incidents
An engineer managing 40+ HIPAA-scoped production databases describes a repeat-incident problem caused by loss of operational context at rotation handoffs. The team introduced a 30-minute structured "readiness review" between outgoing and incoming on-call engineers with a fixed agenda: (1) what paged and why, (2) what changed in the platform, and (3) which runbooks are stale. Runbooks were moved into version control as "runbooks as code" with fields like last_validated and known_repeat to make staleness and repeat incidents visible. A simple SQL grouping to find frequently repeating alerts is provided. The changes correlated with roughly 35% fewer repeat incidents and ~30% lower MTTR; cross-team dependency handoffs remain an open challenge.
- Author manages a platform of 40+ production databases in healthcare with multi-terabyte scale and HIPAA scope.
- Introduced a 30-minute structured readiness review before every on-call rotation handoff with a fixed three-item agenda.
- Moved runbooks into version control ("runbooks as code") with fields such as last_validated, known_repeat, and last_repeat to make staleness and repeats auditable.

AgentATC: Observability for Multi-Agent Coordination
AgentATC is a real three-agent workflow (Planner, Executor, Critic) developed as part of an Agents of SigNoz hackathon to demonstrate observability for multi-agent LLM systems. Unlike traditional APM, AgentATC instruments every inter-agent hand-off as first-class OpenTelemetry spans (e.g., agent.execute, agent.handoff, agent.review), recording initiator, receiver, and reason to make coordination directly observable. SigNoz is used end-to-end for traces, metrics, and logs, with dashboards and alerts (Task Thrashing, Task Stalled) and a Copilot that queries SigNoz MCP Server (signoz_search_traces, signoz_get_trace_details, signoz_search_logs) to diagnose coordination failures. The project exposes failure modes such as thrashing, stalled tasks, and redundant work that standard observability metrics often miss.
- AgentATC implements a real three-agent workflow (Planner, Executor, Critic) to produce a competitive analysis report.
- Every agent hand-off is recorded as an OpenTelemetry span (examples: agent.execute, agent.handoff, agent.review) and includes who initiated, who received, and why the hand-off occurred.
- Traces, metrics, and logs flow through SigNoz; coordination metrics are computed from raw telemetry in SigNoz's query layer and displayed on dashboards (Swarm Health Overview, Thrash Leaderboard).

Deploying SigNoz with ClickHouse v25 and OTel Gotchas
A developer describes troubleshooting and deployment patterns for self-hosting SigNoz in 2026, focusing on ClickHouse v25 configuration changes, OpenTelemetry Collector incompatibilities, and Docker network isolation. Key recommendations include using config.d/users.d for ClickHouse overrides (instead of replacing the main config), enforcing a deterministic docker-compose boot sequence with one-shot migrator containers (signoz_init_clickhouse and signoz_telemetrystore_migrator), updating exporter names and image tags for the OTel collector (use signozclickhousemetrics and include the 'v' prefix), and relying on internal Docker network isolation rather than per-component passwords to simplify connectivity. The post emphasizes that maintaining self-hosted observability infrastructure requires ongoing engineering effort.
- Author self-hosted SigNoz for Verne Software to control telemetry data.
- ClickHouse v25+ changes require using config.d/ and users.d/ for overrides instead of replacing the main config file.
- SigNoz deployments must run one-shot containers (signoz_init_clickhouse and signoz_telemetrystore_migrator) to install UDFs and create required databases before starting collectors.

Integrating AI Agents with Self-Hosted SigNoz
An engineer describes building ArcNet to instrument and monitor an AI agent fleet using a self-hosted SigNoz instance. The write-up covers installation (SigNoz v0.133.0 via foundryctl), lessons about verifying emitted OpenTelemetry attributes (the Agno instrumentor emitted OpenInference conventions rather than gen_ai.*), turning guardrail results into structured span attributes for alerting, the need to use SigNoz's v5 alerts queries payload, using raw ClickHouse SQL panels as an escape hatch, and the distinction between telemetry (traces in SigNoz/ClickHouse) and replayable session transcripts (stored separately in SQLite). The author notes SigNoz MCP was unreliable in their setup and links code on GitHub.
- Author built ArcNet on self-hosted SigNoz for the Agents of SigNoz hackathon.
- SigNoz v0.133.0 was used and installed with foundryctl (casting.yaml + casting.yaml.lock produced reproducible deployments).
- The Agno instrumentor (openinference-instrumentation-agno) emitted OpenInference semantic conventions rather than OpenTelemetry gen_ai.* attributes, causing initially empty dashboards.

Instrumenting MERN E‑Commerce with SigNoz
A developer case study describing how the author instrumented a MERN-stack e-commerce application called Ram Store with SigNoz and OpenTelemetry during the Agents of SigNoz Hackathon 2026. The project used a self-hosted SigNoz instance (Docker) and the OpenTelemetry Node SDK with automatic instrumentation for Express, HTTP, and MongoDB, exporting via OTLP gRPC. The instrumentation enabled distributed traces, runtime metrics, and structured logs (Winston) correlated inside SigNoz. The post covers setup steps, observed telemetry (traces, metrics, logs), challenges (Docker networking, configuration), lessons learned, and planned improvements like custom dashboards and alerting. Project source code and a demo video are linked.
- Author integrated SigNoz into a MERN e-commerce application named Ram Store as part of the Agents of SigNoz Hackathon 2026.
- SigNoz was self-hosted locally using Docker to provide observability dashboards.
- OpenTelemetry Node SDK with automatic instrumentation was configured for Express, HTTP, and MongoDB, using an OTLP gRPC exporter.
