When this workflow is a good fit
Use Grafana when you want dashboards, alert rules, and shared visibility across many services. Grafana normally needs a data source that already exposes certificate expiry as a metric or query result.
Concise setup overview
Choose the data source
Feed Grafana from Prometheus, a synthetic monitoring source, or another integration that records certificate expiry timestamps or days remaining.
Build a certificate expiry panel
Create a table or stat panel showing hostname, issuer, expiry date, and days remaining so risky domains are visible at a glance.
Configure Grafana alert rules
Alert when days remaining drops below your renewal window. Use labels for team, environment, and domain owner so notifications route cleanly.
Verify alert delivery
Preview the rule and test contact points before assuming Grafana will notify you during a real expiry event.
Trade-offs to consider
- •Excellent dashboards, but Grafana is not the certificate checker by itself; it depends on reliable input metrics.
- •Alerting can be complex if the expiry metric has missing labels or scrape gaps.
- •More operational overhead than a purpose-built reminder for a small number of domains.
When to add Certimon
Use Certimon alongside Grafana when you want simple Telegram SSL alerts without building dashboards first, or when you want a separate reminder that is not dependent on your metrics pipeline.
Certimon does not need to replace your observability stack. It is useful as a lightweight second path for certificate-expiry reminders, especially for side projects, client domains, and external domains that are not fully covered by your normal infrastructure monitoring.
