About This Tool

The NFCE SEFAZ Monitor delivers real-time visibility into the availability and health of Brazilian NFCE services. It targets developers, IT ops, ERP teams, and compliance staff who rely on SEFAZ endpoints to issue NFCE. It solves the problem of undetected outages and intermittent latency by collecting standardized health metrics, including endpoint reachability and response times, and presenting a consolidated health summary suitable for dashboards and audits.

Conceptually, users configure basic identity inputs (CNPJ, UF, environment) and optional version and endpoints. The service performs lightweight health checks at configured intervals, records results with timestamps, and aggregates results into a health score or category per endpoint. The output supports drill-down by endpoint and time-range, enabling post-incident analysis and SLA verification.

The tool's unique value lies in domain alignment with NFCE and SEFAZ variances across states, support for homologacao and producao, and easy integration with automation pipelines. Use cases include pre-release verification, live dashboards, incident retrospectives, and vendor risk assessment. Core features include endpoint-level health, interval configuration, historical logs, and simple export formats to CSV or JSON for reporting.

No UI talk; addresses common pain points for teams building or operating NFCE solutions and seeking reliable health signals to maintain throughput and compliance.

How to Use

  1. Provide inputs: supply cnpj, uf, environment, and optional nfce_version and endpoint_base. Sample: cnpj=
  2. 678/0001-95, uf=SP, environment=homologacao.
  3. Configure: set check_interval_sec (e.g.,
  4. and enable any endpoint-specific thresholds.
  5. Run checks: the tool initiates periodic health checks and records results.
  6. Review outputs: inspect status, last_checked, response_time_ms, and endpoints_health for each service.
  7. Export or alert: export to CSV/JSON for reporting or configure alerts for degraded/offline states.

Frequently Asked Questions

Find Quick Answers

What does this monitor?
It tracks NFCE SEFAZ endpoints used for Brazilian electronic invoices, reporting overall health, individual endpoint status, and latency to support uptime and SLA verification.
What inputs are required?
Required inputs include the CNPJ, UF code, and environment (producao or homologacao). Optional inputs cover nfce_version, endpoint_base, and check_interval_sec to customize checks.
How is health classified?
Health is classified as online when all critical endpoints respond OK within thresholds; degraded when some endpoints are slow or intermittently failing; offline when key endpoints are unreachable for a defined period.
Is data retained long-term?
The tool stores timestamped health data for trend analysis and audits. retention duration is configurable in deployments and reporting pipelines; raw data may be purged according to policy.
