Pulse Health Checks

Combine the power of Laravel Pulse with Spatie's Health Checks

Installation

You can install the package via composer:

composer require chris-ware/pulse-health-check

Usage

Cache Hit Ratio Check

This check will warn or fail if the cache hit ratio hits a certain percentage threshold. By default, it will fail at 10% hit ratio and warn at 25%.

use ChrisWare\PulseHealthCheck\Checks\PulseCacheHitRatioCheck;

PulseCacheHitRatioCheck::new();

Configure the failure and warning levels:

use ChrisWare\PulseHealthCheck\Checks\PulseCacheHitRatioCheck;

PulseCacheHitRatioCheck::new()->failWhenSizeRatioBelow(25)->warnWhenSizeRatioBelow(50);

Generic Check

This generic check will accommodate most basic circumstances for Pulse aggregates. Every check must have a defined for method on it for it to understand which aggregate type to use.

Example for slow query aggregation:

use ChrisWare\PulseHealthCheck\Checks\PulseCheck;

PulseCheck::new()
    ->for('slow_query')
    ->failWhenAbove(5)
    ->warnWhenAbove(3)
    ->interval(\Carbon\CarbonInterval::minutes(5));

Example for user request aggregation:

use ChrisWare\PulseHealthCheck\Checks\PulseCheck;

PulseCheck::new()
    ->for('user_request')
    ->aggregate('count')
    ->failWhenAbove(500)
    ->warnWhenAbove(300)
    ->interval(\Carbon\CarbonInterval::minutes(5));

Available methods
