Healthie.NET.Abstractions

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.

Core interfaces, models, enums, and the PulseChecker abstract base class for the Healthie.NET health monitoring framework. This package contains no implementations -- only the contracts and types that all other Healthie.NET packages depend on.

Installation

dotnet add package Healthie.NET.Abstractions

Usage

Inherit from PulseChecker and override CheckAsync to implement a health check:

using Healthie.Abstractions;
using Healthie.Abstractions.Enums;
using Healthie.Abstractions.Models;
using Healthie.Abstractions.StateProviding;

public class DatabasePulseChecker : PulseChecker
{
    private readonly IDbConnectionFactory _db;

    public DatabasePulseChecker(IStateProvider stateProvider, IDbConnectionFactory db)
        : base(stateProvider, PulseInterval.Every30Seconds, unhealthyThreshold: 3)
    {
        _db = db;
    }

    public override async Task<PulseCheckerResult> CheckAsync(
        CancellationToken cancellationToken = default)
    {
        using var conn = await _db.CreateConnectionAsync(cancellationToken);
        return new PulseCheckerResult(PulseCheckerHealth.Healthy, "OK");
    }
}

Key Types

Type Description
PulseChecker Abstract base class -- inherit to create a health check.
IPulseChecker Full pulse checker contract (IPulse + IState + IAsyncDisposable).
IStateProvider Contract for state persistence (GetStateAsync / SetStateAsync).
IPulseScheduler Contract for scheduling (ScheduleAsync / UnscheduleAsync).
PulseCheckerResult Record returned from CheckAsync with Health and Message.
PulseCheckerState Record holding interval, threshold, failure count, history, tags, group, pin, and last result.
PulseCheckerHealth Enum: Healthy, Suspicious, Unhealthy.
PulseInterval Enum: 13 intervals from EverySecond to Every5Minutes.
HealthieOptions Global options (e.g. MaxHistoryLength).

Describing a checker

A checker can say where it belongs and what it is, and both are picked up by the dashboard.

public class RedisCachePulseChecker(IStateProvider stateProvider) : PulseChecker(stateProvider)
{
    public override string DisplayName => "Redis Cache";

    // One group at most: this is where the checker lives.
    public override string DefaultGroup => "Data Stores";

    // Any number of tags: these describe it, and may cut across groups.
    public override IReadOnlyList<string> DefaultTags => ["tier-1", "cache"];

    public override Task<PulseCheckerResult> CheckAsync(CancellationToken cancellationToken = default)
        => /* ... */;
}

Both seed PulseCheckerState the first time a checker runs and are never applied again, so a change made later -- through SetGroupAsync / SetTagsAsync, or on the dashboard -- survives a restart rather than being reset to what the code says.

SetPinnedAsync sorts a checker above the rest. A pin is stored with the checker rather than per viewer, on the grounds that the checks worth watching are the same for everyone.

### Fixed

- **The dashboard cropped its own rows on anything narrower than a laptop.** The row and its column
 header share one track definition, and two rules overrode it: a read-only board drops the controls
 column, and a narrow viewport folds the row down to three. Written as separate rule sets they
 fought on specificity, and `.hpm-list--readonly .hpm-row` outranks a `.hpm-row` inside a media
 query -- so on a read-only board the fold never applied at any width. Every row was drawn with
 five tracks demanding 556px inside a 342px phone: 214px of columns clipped off the right, the name
 squeezed to its 160px minimum to make room for columns that were not visible anyway, and no
 scrollbar to reach them, because the overflow was clipped rather than scrolled. The definition is
 now a single custom property on the list, which is the one element both variants already sit on,
 so the fold cannot be outranked.
- **The last column was clipped on an ordinary 1280 laptop, read-only or not.** The detail panel
 moved below the list at 1100px, but a full row needs a 706px column and the list only reaches that
 at 1402px of viewport -- so between those two the three columns fitted the window while the middle
 one no longer fitted a row. That threshold is now 1400px, calibrated on the editable board, which
 is the wider of the two and the default.
- **Group and tag chips were sliced down the middle on a phone.** They sit on the row's sub-line,
 which truncates with `text-overflow: ellipsis` -- and that ellipsizes text, not an inline-flex
 pill, so a chip was cut mid-shape instead. The folded row has vertical room the wide one does not,
 so the line now wraps there, exactly as it already does on a card.
- **Cards lost their rate, sparkline and last-checked time on a phone.** The three cells were hidden
 for every layout below 820px, but only the row layout was short of width; a card stacks them into
 areas down its own length, where they fit. They are now hidden for the row layout alone.

### Changed

- **The packages point at [healthie-dotnet.dev](https://healthie-dotnet.dev/).** `PackageProjectUrl`
 is the landing site rather than the repository, because NuGet renders it as the package's "Project
 website" and a reader who clicks it wants documentation and the live board, not a source tree.
 `RepositoryUrl` still points at GitHub, so Source Link and NuGet's own source link are unaffected.
 Every package README now links the documentation site alongside the live demo, which moved to
 [board.healthie-dotnet.dev](https://board.healthie-dotnet.dev/).
- **Releases carry build provenance.** The release workflow attests which workflow, at which commit,
 produced each package, so `gh attestation verify <package>.nupkg --repo ivanvyd/Healthie.NET`
 proves a download came from this repository. The SBOM already said what went into a package; this
 says who built it, which is the half a tampered build would otherwise be free to restate.
- The repository README leads with a screenshot rather than a 10MB animation, and `Healthie.NET.Redis`
 gained the header every other package README already had.
