The one non-serverless piece — Grafana OSS on a t4g.small (AL2023, ARM64) in the
imported seahaven-vpc, fronted by an internet-facing ALB locked by SG to the
office CIDRs (no Client VPN exists, so "VPN-only" = office-IP restriction, the
syslog-server pattern). Instance in private subnets, reachable only from the ALB
SG, administered via SSM Session Manager (no SSH/key pair).
grafana_stack.py: ALB (HTTPS, *.seahaven.com cert, open=False so the SG office
rules aren't undone by an auto 0.0.0.0/0), instance role (Athena query + Glue
read + S3 analytics/athena-results, no static keys), Route53 grafana.seahaven.com
alias, gp3 root volume RETAINed, daily DLM snapshot of the tagged instance, and a
BucketDeployment that uploads grafana/ to the S3 config prefix.
grafana_userdata.sh: install Grafana OSS, pin the Athena datasource plugin, write
grafana.ini (root_url grafana.seahaven.com, kiosk embedding), sync provisioning +
dashboards from S3 on boot, and a systemd timer re-syncs every 15 min so repo
edits land without an instance rebuild.
Dashboard (grafana-author agent, grafana/dashboards/apm-work-orders.json, uid
apm-wo so the Slack 📊 button resolves): 7 panels — category distribution,
escalation summary, action/routine, escalations-by-site, trend time-series over
dt (the new capability), filterable WO table (5 template vars, escalation row
coloring, CSV export, no APM links), and the mismatch panel. Datasource uid
"athena" pinned in the provisioning yaml.
Tests: tests/test_grafana_synth.py — ALB admits only the office CIDRs on 443
(caught and fixed a default 0.0.0.0/0 listener rule), instance only-from-ALB,
no static keys, scoped instance role + SSM, gp3+retained root volume, daily DLM
backup, grafana.seahaven.com alias. 57/57 tests pass; full cdk synth green.
