Healthie.NET - Trust your uptime

Healthie.NET.Temporal

NuGet

▶ Live demo — board.healthie-dotnet.dev — a read-only Healthie.NET dashboard watching real status pages (Anthropic, OpenAI, GitHub, Cloudflare, and more), built from these packages. Full documentation at healthie-dotnet.dev.

Schedules pulse checks with Temporal, so the schedule lives in the cluster rather than in the process.

Installation

dotnet add package Healthie.NET.Temporal

Usage

using Healthie.Scheduling.Temporal;
using Temporalio.Extensions.Hosting;

builder.Services.AddSingleton<ITemporalClient>(await TemporalClient.ConnectAsync(new("localhost:7233")));

builder.Services
    .AddHealthie(typeof(Program).Assembly)
    .AddHealthieTemporal(options => options.TaskQueue = "healthie");

// A worker must be listening on the same queue, or the schedules fire and nothing runs.
builder.Services
    .AddHostedTemporalWorker("healthie")
    .AddScopedActivities<PulseCheckerActivities>()
    .AddWorkflow<PulseCheckerWorkflow>();

The Temporal client is yours to create: its address, namespace, TLS and API key are your decisions, and a library that picked them would be picking which cluster your workflows run on.

What it buys, and what it costs

Buys: the schedule survives a restart and a redeploy, each occurrence is handed to exactly one worker however many replicas are running, and every run has a history somebody can look at.

Costs: a Temporal cluster. If you do not already run one, this is the wrong trade — Healthie.NET.Hangfire gives you the same survives-a-restart, runs-once-across-replicas properties against a database you probably already have, and the built-in timer needs nothing at all.

The SDK also carries a native Rust core, so it is a large dependency: it adds a few hundred megabytes to a build output. Worth knowing before adding it to something small.

Details

Schedules are named healthie-<checker name>, so they are recognisable in the Temporal UI and cannot collide with your own.

Overlap policy is Skip. A checker already refuses to run on top of itself, so buffering would queue occurrences that each return immediately — and a check that is late is worth less than the next one, which is current.

Cron expressions use Healthie.NET's standard Unix form: five fields, or six with leading seconds. Temporal uses seven fields when seconds are present because its sixth field is a year, so the adapter appends a wildcard year to Healthie.NET's six-field form. Fixed periods become interval specs, which Temporal counts from an epoch rather than from creation time, so replicas agree on when a schedule fires. Temporal's one-second minimum is validated before an existing schedule is replaced.

The workflow does nothing but call an activity — workflow code must be deterministic, and a pulse check is not — and the activity is given the checker's name, because a schedule outlives the process that created it and a checker does not survive being serialized.

Testing

The mapping from a schedule to a Temporal specification is unit-tested. Everything else needs a running cluster, so it is not exercised in the default test suite — that suite deliberately requires no infrastructure. Run it against a dev server (temporal server start-dev) when changing this package.

### Fixed

- The dashboard event-log and about dialogs now move focus inside, keep keyboard focus contained,
 close with Escape, and restore focus to the control that opened them.
- Dashboard checker rows now expose selection as a real button alongside their action buttons,
 removing nested interactive controls while preserving whole-row pointer selection.
- A dashboard state-provider failure now shows a recoverable unavailable state with a retry action
 instead of looking like an empty installation with no registered checkers.
- The Blazor sample now keeps the dashboard stylesheet in its static host head, preventing an
 unstyled flash while the interactive head reconnects on a slow network.
- HTTP checker display names and result messages now omit URI user information, query strings, and
 fragments, server-controlled reason phrases, and transport exception details, preventing embedded
 credentials and tokens from reaching stored history, alerts, logs, or the dashboard while requests
 still use the complete configured URI.
- Alert-history persistence now loads durable history before its first post-restart write and
 coalesces changes raised during a slow state-provider write into one latest-state follow-up. This
 preserves earlier alerts without duplicating the new one and avoids an unbounded queue of tasks
 and redundant full-history writes during alert bursts.
- The Web API sample maps its unauthenticated management API and mutation-enabled MCP endpoint only
 in Development, so deploying the sample with a production environment no longer exposes those
 local demonstration surfaces. Liveness and readiness probes remain available.
- History clearing and startup trimming now use optimistic concurrency, so they no longer overwrite
 a check result or setting changed by another replica between the read and write.
- Leader election now serializes schedule changes with leadership transitions and reconciles every
 registered checker's persisted active state and schedule through a bulk read on lease renewal. A
 pause or cadence change made through another replica now reaches the leader, a fresh leader
 removes inactive durable jobs left by the previous process, and reconciliation runs with bounded
 concurrency while an independent lease heartbeat prevents slow scheduler calls from expiring an
 otherwise healthy leader. Partial and cancelled transitions remain tracked until cleanup succeeds,
 and shutdown does not release the lease over work it could not stop.
- CosmosDB multi-state reads now use `ReadManyItemsAsync`, avoiding one sequential network round
 trip per checker during dashboard loads and leader renewal.
- The in-memory lease provider now returns exactly one winner when replicas contend concurrently.
- Coravel, Hangfire, Temporal, and the leader-election decorator now validate schedules before they
 are persisted. Cronos expressions requiring an absent jitter seed are reported as validation
 failures instead of escaping as server errors. The built-in timer also rejects periods outside
 `PeriodicTimer`'s supported range before replacing a working schedule.
- Temporal now preserves Healthie.NET's six-field, leading-seconds cron meaning by translating it
 to Temporal's seven-field seconds form. It rejects Cronos-only relative-day and descending-range
 expressions whose Temporal meaning differs, and fixed periods outside Temporal's supported range,
 before an existing schedule is removed.
- Uptime recording now starts a new observation segment on the first fresh result after a process
 restart, even when its health matches persisted state. Time while no process was observing the
 checker remains unknown, and a transition that finds the bounded queue full is retried by the next
 fresh result.
