Remove legacy assets/ directory (pre-Astro era). Images were already
duplicated under site/public/images/; update README sponsor URLs to
point to the new location.
@astrojs/tailwind v6 still requires tailwindcss@^3; replace it with the
official @tailwindcss/vite Vite plugin. Update global.css to v4 syntax
(@import "tailwindcss", @custom-variant dark, @theme tokens) and drop
the now-unused tailwind.config.mjs.
* feat: migrate website from Jekyll to Astro
Rebuilds the site using Astro (SSG) with Tailwind CSS v4, replacing the
Jekyll/Cayman theme. Key changes:
- Splits the monolithic /rules page into 110 statically-generated pages
(92 per-service + 13 group index + homepage + guide pages) for SEO
- URL structure: /rules/[group-slug]/[service-slug]/ with backward-
compatibility redirect map for old anchor-based URLs (/rules#redis)
- Modern UI: Prometheus-orange accent, dark mode (system + toggle),
sticky sidebar, responsive layout, copy-to-clipboard per rule/section
- SEO: per-page <title>, <meta description>, Open Graph, Twitter Card,
canonical URLs, sitemap.xml via @astrojs/sitemap
- GEO: FAQPage JSON-LD schema on each service page (rules as Q&A pairs
for AI search engines), TechArticle schema, BreadcrumbList
- Search: Pagefind (build-time index, lazy-loaded, ~200KB)
- Zero JS by default; copy buttons and theme toggle use inline scripts
- New CI: .github/workflows/deploy.yml builds Astro + Pagefind and
deploys to GitHub Pages via actions/deploy-pages
- Existing dist.yml and test.yml workflows are untouched
- _data/rules.yml remains the single source of truth
Note: GitHub Pages source must be changed from "Build from branch"
(Jekyll) to "GitHub Actions" in repository settings.

* fix: strip trailing slash from BASE_URL to prevent double slashes in URLs

* fix: resolve Astro build errors in astro.config.mjs
- Remove assetsInclude yml which caused Vite to treat YAML files as static assets instead of running them through the custom YAML transform plugin; data.groups was undefined at runtime because the import resolved to a URL rather than parsed content
- Deduplicate old-path redirects: emit only the slash-less variant per service to avoid Astro router collision warnings (trailing-slash variant is handled automatically)

Add guidance on untyped metrics with counter semantics (node_vmstat_*,
MySQL SHOW GLOBAL STATUS), YAML duplicate key pitfall, permanent-firing
cumulative counter alerts, and updated category structure.
Add Prometheus alerting rules for Oracle Database using iamseth/oracledb_exporter.
Rules based on Grafana oracledb-mixin and exporter default metrics:
- DB down, session/process limit, tablespace capacity (warning+critical),
high rollbacks, active sessions, user I/O wait time.
* feat: add Grafana Tempo and Grafana Mimir alerting rules (67 rules)
Add 18 Tempo rules and 49 Mimir rules based on official upstream mixins.
Covers ring health, compaction, TSDB, instance limits, ruler, alertmanager, and more.
* fix: address PR review comments on Tempo/Mimir rules
- Fix Tempo no tenant index builders: add on() for cross-label-set and
- Fix Tempo block list rising: output percentage instead of ratio
- Fix Mimir memory map areas: multiply by 100 to match % description
- Fix all instance limit rules: multiply by 100 to match % descriptions
- Fix distributor inflight requests: add % to description
* Add .worktrees/ to .gitignore
* feat: add Jaeger alerting rules (8 rules from official jaeger-mixin)
Rules cover agent HTTP errors, RPC errors, client/agent/collector span drops,
sampling update failures, throttling update failures, and query request failures.
All rules sourced from https://github.com/jaegertracing/jaeger/tree/main/monitoring/jaeger-mixin
* fix: rename Jaeger agent RPC alert to Jaeger client RPC
The jaeger_client_jaeger_rpc_http_requests metric is client-side,
not agent-side. Rename alert to match the actual metric source.
* feat: add systemd_exporter alerting rules (7 rules)
Add new Systemd service under Basic resource monitoring with rules for:
- Unit failed/inactive state detection
- Service crash loop detection
- Task limit exhaustion
- Socket refused/high connections
- Timer missed trigger
* fix: narrow systemd unit inactive query to reduce noise
Add type="service" and name filter to the inactive unit alert
to avoid false positives from legitimately inactive units.
* feat: add Cloud providers alerting rules (33 rules across 4 exporters)
New "Cloud providers" category with rules for:
- AWS CloudWatch (13 rules): exporter health + EC2, RDS, SQS, ALB, Lambda
- Google Cloud / Stackdriver (5 rules): scrape health, API quotas, staleness
- DigitalOcean (10 rules): droplets, databases, k8s, load balancers, incidents
- Azure (5 rules): API errors, rate limits, collection performance
* fix: address PR review - move Cloud providers before Other, fix service name
- Move "Cloud providers" group before "Other" in rules.yml for consistent ordering
- Rename "Google Cloud / Stackdriver" to "Google Cloud Stackdriver" to avoid
awkward /-/ in generated anchors and dist/rules/ paths
- Fix README anchor link to match the new service name
* fix: use proper zero-traffic guard in Envoy ratio alerts (#511)
Replace `+ 1` denominator hack with `and ... > 0` filter in upstream
timeout rate and upstream 5xx error rate queries for mathematical
correctness and repo consistency.
* feat: add alerting rules for prometheus/memcached_exporter
* fix: add division-by-zero guards and improve quoting in memcached rules (#512)
- Add `and memcached_max_connections > 0` to connection limit queries
- Add `and memcached_limit_bytes > 0` to memory usage query
- Switch hit-rate query to single quotes for cleaner PromQL readability
* fix: fix SNMP interface down query and add job scoping (#507)
- Fix ifOperStatus query to use vector matching instead of label filter
since ifAdminStatus is a separate metric in snmp_exporter output
- Add job=~"snmp.*" matcher to interface error rate, bandwidth usage,
and interface down rules to prevent matching non-SNMP series
* Potential fix for pull request finding
