v0.14.4: Introducing Script Probes, plus SQL and gRPC Sidecar Probes

This release introduces Starlark script probes — write real probe logic in a sandboxed scripting language, with cross-run state, custom metrics, JWT/OAuth auth, and full HTTP control — alongside two more new major probe types, SQL and EXTERNAL_GRPC. Several CI, security, and docs improvements round things out.

🧩 New: Script Probes (Starlark)

The headline feature of this release is the script probe — write your probe logic directly in Starlark, a small, sandboxed, Python-like language embedded in Cloudprober.

Plenty of real checks don't fit a single HTTP request: log in, grab a token, call an API with it, assert on something in the response body, then emit a metric derived from what you found. Until now that meant either an external probe (a separate binary, process-per-run, no structured contract) or a patch to Cloudprober itself. Script probes let you express that logic inline in your config — no extra binary to build, ship, or version — while still getting the standard latency, success, and failure metrics plus full alerting integration that every other probe type gets. Scripts run sandboxed with no filesystem or arbitrary network access beyond the builtins Cloudprober exposes, so config authors can't accidentally turn a probe into a shell.

What's available at launch:

• Core builtins: vars (probe-level variables exposed to scripts), log (with set_attr for per-run logger attributes), state (per-target memory that persists across runs), and print_metric (emit your own custom metrics).
• HTTP: http.get/put/patch/delete, max_redirects and keep_alive kwargs, tls_config for custom CA / mTLS / SNI / skip-verify, and per-call TLS selection via a tls= kwarg.
• Auth: jwt.encode for JWT-bearer APIs, and an oauth builtin for token and header handling.
• Assertions: assert.http_status for checking response codes.
• Docs: a Script Probe (Starlark) how-to, surfaced on the top-of-funnel pages.

🔌 Two More New Probe Types

SQL Probes

Cloudprober can now probe SQL databases directly, starting with a POSTGRES flavor. Until now, checking database health meant either bolting on an external exporter or writing a custom probe just to run a query and check the result. With a native SQL probe type, you can point Cloudprober at a Postgres instance, run a query on a schedule, and get the same latency/success/failure metrics and alerting integration as every other probe type — connection health, query latency, and query-result validation all become first-class signals alongside your HTTP and gRPC checks. It's a foundation to build on: the flavor-based design means support for other SQL backends (MySQL, etc.) can be added without changing the probe's config surface.

EXTERNAL_GRPC Probes

This is the biggest architectural addition in the release: a new EXTERNAL_GRPC probe type that delegates the actual probe run to a gRPC sidecar process, with full TLS/mTLS support for securing that connection.

Cloudprober has long supported EXTERNAL probes (shelling out to an external binary), but that model is limited — no structured request/response, no streaming, and process-per-run overhead. EXTERNAL_GRPC replaces that with a proper gRPC contract: Cloudprober calls out to a long-lived sidecar over a defined protocol instead of spawning a process each run. That unlocks probe logic in any language with a gRPC library — not just what you can compile into Cloudprober's Go binary — while keeping the sidecar process warm and stateful between runs. It's the cleanest path yet for teams who want to write custom, complex probe logic (e.g. multi-step business transactions, non-HTTP protocol checks) without forking Cloudprober itself, and the added mTLS support means that sidecar boundary can be locked down for production use.

🔔 Alerting

• New Microsoft Teams notifier (thanks @dmesad!).
• Added a 30s timeout to notifications; fixed Slack typos/headers; cleaned up variable names and constants across Slack and Teams notifiers.
• Command notifier now reaps child processes correctly.

🌐 HTTP Probes

• Dynamic headers, including @uuid@ substitution.
• Dynamic headers are now logged on probe errors; Host header substitution was dropped.

🛠️ Other Fixes & Improvements

• File surfacer: fixed 32-bit alignment for atomic operations, made close() idempotent (thanks @amdw!).
• Postgres surfacer: now uses pgxpool to recreate connections after drops (thanks @markoposavec!).
• Config parsing: bufio.Scanner errors are now surfaced during parsing (thanks @karlpvoss!).
• Surfacer additional labels: validation now trims whitespace before checking (thanks @immanuwell!).
• json_metric now accepts integer jq results.
• Browser probes: new internal_errors metric for missing-toolchain failures and browser-launch timeouts; Dockerfile.pw now calls playwright directly and installs ca-certificates.
• External serverutils: fixed a late-binding closure bug and a logging error.
• Go and dependencies upgraded to address vulnerabilities, including CVE-2026-53486 (decompress path traversal).

📚 Docs & Site

• Homepage modernized: tightened hero-to-logos spacing, slimmed the trusted-by band, fixed footer links (Resources, Browser Probe, Blog → Medium, How-to/FAQ), and corrected the hero font.
• Config docs version dropdown now sorts newest-first; CI fixed to pick up new release tags in "all" mode.

🧰 CI / Build

• Enforced pinned dependency versions across Go (go mod download), npm (npm ci), and Python (py_serverutils).
• Sped up the Go build/test workflow; regenerated gRPC proto code.
• Bumped CI Node to 20 for @xhmikosr/decompress.

v0.13.6

What's Changed

Targets improvements

• [targets.resolver] Make cloudprober's resolver more reliable. Note this resolver gets triggered only
  if you configure resolve_first in your probe.
  • On failure, attempt refresh on each resolve call. Earlier, we'll wait for the cache TTL to expire,
    causing delays in getting a good resolution. by @manugarg in #753, #755
• [targets.resolve] Provide a way to specify network for DNS server override. This will allow users to
  use DNS servers over TCP, which may be critical in enterprise/firewall setting where UDP is sometimes
  restricted. by @manugarg in #756
• [targets.file] Support YAML format for target files and allow specifying URLs in resources. This will
  make specifying targets through files even more convenient. by @manugarg in #777, #778

Surfacers improvements

• [surfacers] Ignore sysvars metrics for file surfacer added by default. This is to reduce noise in default
  logs. by @manugarg in #749.
• [config] Provide a way to specify surfacers config independently. This will allow multi-tenant
  deployments to configure surfacers centrally. by @manugarg in #750.
• [surfacers] Provide a way to add labels to all metrics through environment variables. by @manugarg
  in #759.

HTTP Probe

• [probes.http] Provide a way to read request body from a file. by @manugarg in #782
• [probes.http] Allow specifying proxy connect headers by @manugarg in #763
