Add send_certificate_cost_metrics() to emit per-cert annual cost (certificates.annual_cost, gauge USD), a per-cert count (certificates.count), and a fleet total (certificates.total_annual_cost) tagged with issuer, cert_type, cert_name, owner, expiration and status (active/replaced/expired/ revoked/ca). Pricing: DigiCert FQDN $150, DigiCert wildcard $550, Sectigo wildcard OV $400 (assumed), Let's Encrypt free. Wire it into the certificates CLI (cost_metrics command) and the certificate_expirations_metrics celery task so the 'Lemur Certificate Cost Basis' dashboard (wsp-8mi-daz) populates.

What
Adds
send_certificate_cost_metrics()tolemur/certificates/service.py, acost_metricsCLI command, and a hook in thecertificate_expirations_metricscelery task so Lemur emits per-certificate annual cost gauges:lemur.certificates.annual_cost(gauge, USD) — one point per cert; sum = fleet costlemur.certificates.count(gauge, 1) — one point per cert for countinglemur.certificates.total_annual_cost(gauge, USD) — fleet totalTags:
issuer,cert_type(fqdn|wildcard_san),cert_name,owner,expiration,status(active|replaced|expired|revoked|ca). Thestatustag lets the dashboard split ongoing vs gross cost basis.Pricing rules (annual USD — all estimates for cost-basis governance)
Pricing lives in
CERT_ANNUAL_PRICEin service.py and is mirrored in the Datadog reference tablelemur_certificate_pricingand the 'Lemur Certificate Cost Basis' dashboard (wsp-8mi-daz).Why
Populate the 'Lemur Certificate Cost Basis' dashboard with real metric data for certificate cost governance.
Tests
test_send_certificate_cost_metricscovering DigiCert FQDN/wildcard, Let's Encrypt free, Sectigo wildcard, and unpriced certs.test_send_certificate_expiration_metricsstill passes; fulltest_certificates.pyhas the same 10 pre-existing failures as master (Vault not configured for private-key tests).
