Saved, shareable multi-panel dashboards (table/line/bar/single-stat panels via gridstack + uPlot, global + per-panel time range, JSON export/import) and threshold/absence alert rules with an ok/pending/firing evaluator and webhook/Slack/PagerDuty delivery. - New /metadata component: Postgres control-plane store for dashboards, panels, notification targets, alert rules/state, and delivery log -- see docs/phase-3-dashboard-design.md for why ClickHouse's MergeTree family isn't a fit for this access pattern (needs real row-level locking and read-your-writes consistency). - api/internal/dashboards: dashboard/panel CRUD, pure -- panel query execution stays client-side, reusing the existing /query endpoint. - New /alerting service: rule/target CRUD, a ticker-driven evaluator (claim-then-evaluate concurrency control, transactional-outbox delivery, query errors and threshold zero-rows never coerced into a false transition) and webhook/Slack/PagerDuty delivery with retry/backoff. See docs/phase-3-alerting-design.md for the full state-machine design and the four correctness properties it implements. - web: /dashboards and /alerts UIs; cli: sentryctl dashboards/alerts list/get/apply, seeding a future Terraform provider's JSON contract. - hack/alert-load-test: 500 rules against real ClickHouse data, real measured results in docs/phase-3-runbook.md. Five real bugs found by actually running this against a live stack (documented in the runbook, not just fixed silently): a latent Phase 2 bug where ClickHouse rejected the timestamp format used for earliest=/latest= queries; a "now" literal token injected into query text; a GridStack/uPlot layout-timing race; JS's Date.parse being too lenient to use as a timestamp-detection heuristic; a rule's "enabled" field silently defaulting to false when omitted; and the evaluator's claim-batch-size and worker-pool-concurrency defaulting to the same value, causing 500 concurrently-due rules to take 125s to cycle through instead of the configured 60s.
sentryctl
Sentry's control CLI.
sentryctl ping # checks http://localhost:8080/healthz
sentryctl ping --api http://api.internal:8080
SENTRYCTL_API_URL=http://api.internal:8080 sentryctl ping
Exits 0 and prints ok if /api's /healthz responds 200; exits 1 with an
error on stderr otherwise.
sentryctl query 'service=api | where status>=500 | stats count by host'
sentryctl query 'SELECT * FROM logs LIMIT 10' --language sql
sentryctl query 'message:"connection refused"' --json
Quote the query in your shell — pipe syntax uses |, which your shell
interprets as an actual pipe if you don't. Hits the exact same POST /query endpoint the web UI does (internal/querylang in /api does the
compiling; there's no separate query logic here to drift out of sync —
see /docs/query-language-reference.md). --language overrides
auto-detection, same optional override the HTTP API itself exposes.
Prints a table by default (stdlib text/tabwriter, no new dependency);
--json prints the raw {columns, rows} response instead.
sentryctl dashboards list
sentryctl dashboards get <id>
sentryctl dashboards apply dashboard.json # imports a dashboard exported via the web UI's "Export JSON" button
sentryctl alerts list
sentryctl alerts get <id>
sentryctl alerts apply rule.json # creates a rule from a JSON file shaped like POST /rules's body
dashboards talks to /api (--api, same override as query/ping).
alerts talks to /alerting, a separate service with its own base URL
(--alerting-api, or $SENTRYCTL_ALERTING_API_URL, default
http://localhost:8081) — see /docs/phase-3-alerting-design.md's
component boundary for why alerting isn't just another /api route.
apply in both cases sends the file's JSON as-is to the corresponding
create/import endpoint — no reshaping, since the file's shape already
matches what the endpoint expects (the same JSON the web UI's export
button downloads, or the same shape GET /rules/{id} returns). This is
deliberately the seed of a future Terraform provider: one JSON contract,
multiple callers (web export, CLI apply, eventually a provider), not
three different formats to keep in sync.
No CLI framework (cobra/urfave-cli/etc.) — six commands split across a
few files (cmd_ping.go, cmd_query.go, cmd_dashboards.go,
cmd_alerts.go) is still boring enough not to need one; stdlib
os.Args handling plus a hand-rolled switch in main.go covers it.
Revisit once there's a real command tree (nested subcommands, nontrivial
flag parsing) to justify a dependency.
