This package checks if the application resources are running as they should and creates a service status panel. It has the following main points:
Heath has pre-configured resource checkers for the following services:
But you can add anything else you need, you just have to find the right checker to use or just create a new checker for your resource.
If you have a lot of websites to check, you can use the HealthPanel checker to create a Health Monitor application to check all your remote monitors and create a dashboard to summarize the state of all your websites.
Creating new resources monitors is easy, just create a new YAML file in app's config/health folder and it's done. Here's some examples:
name: S3
abbreviation: s3
checker: PragmaRX\Health\Checkers\CloudStorageChecker
notify: true
driver: s3
file: pragmarx-health-s3-testfile.txt
contents: {{ str_random(32) }}
error_message: 'Amazon S3 connection is failing.'
column_size: 4
name: NginxServer
abbreviation: ngnxsrvr
checker: PragmaRX\Health\Checkers\ProcessChecker
command: 'pgrep %s'
method: process_count
process_name: nginx
instances:
minimum:
count: 4
message: 'Process "%s" has not enough instances running: it has %s, when should have at least %s'
maximum:
count: 8
message: 'Process "%s" exceeded the maximum number of running instances: it has %s, when should have at most %s'
notify: true
pid_file_missing_error_message: 'Process ID file is missing: %s.'
pid_file_missing_not_locked: 'Process ID file is not being used by any process: %s.'
column_size: 4
If you have lots of services to check, you may change the default panel design to use less space:
Mouse over a failing resource and get instant access to the error message:
Click the resource button and you'll get an alert showing the error message:
Here's an example of notification sent via Slack:
The health check commands below also return an exit code in a standard format:
Numeric Value | Service Status | Status Description |
---|---|---|
0 | OK | Service and appears to be functioning properly |
1 | Warning | Check ran okay, but was above some "warning" threshold |
2 | Critical | The check detected service is not running or is above a "critical" threshold |
3 | Unknown | Settings for the service check may be misconfigured and is preventing the check for being performed |
Use the command health:panel
to view the status of your services in console.
Use the command health:check
to check all your resources and send notifications on failures.
After installing you will have access to the following routes:
The main panel route.
Returns a json with everything the package knows about your services:
Returns a string with status on all your services, useful when using other monitoring services:
hlthFAIL-dbFAIL-filesystemOK-frmwrkOK-httpOK-httpsOK-mailOK
Returns a json with information about a particular service:
Use Composer to install it:
composer require pragmarx/health
Add the Service Provider to your config/app.php
:
PragmaRX\Health\ServiceProvider::class,
php artisan vendor:publish --provider="PragmaRX\Health\ServiceProvider"
http://yourdomain.com/health/panel
Almost everything is easily configurable in this package:
Some of the checkers need you to configure the proper binary path for the checker to work:
'services' => [
'ping' => [
'bin' => env('HEALTH_PING_BIN', '/sbin/ping'),
],
'composer' => [
'bin' => env('HEALTH_COMPOSER_BIN', 'composer'),
],
],
To receive notifications via Slack, you'll have to setup Incoming Webhooks and add this method to your User model with your webhook:
/**
* Route notifications for the Slack channel.
*
* @return string
*/
public function routeNotificationForSlack()
{
return config('services.slack.webhook_url');
}
When Health result is cached, you can flush the cache to make it process all resources again by adding ?flush=true
to the url:
http://yourdomain.com/health/panel?flush=true
If you prefer to build you own notifications systems, you can disable it and listen for the following event
PragmaRX\Health\Events\RaiseHealthIssue::class
Broadcasting checker is done via ping and pong system. The broadcast checker will ping your service, and it must pong back. Basically what you need to do is to call back a url with some data:
var request = require('request');
var server = require('http').Server();
var io = require('socket.io')(server);
var Redis = require('ioredis');
var redis = new Redis();
redis.subscribe('pragmarx-health-broadcasting-channel');
redis.on('message', function (channel, message) {
message = JSON.parse(message);
if (message.event == 'PragmaRX\\Health\\Events\\HealthPing') {
request.get(message.data.callbackUrl + '?data=' + JSON.stringify(message.data));
}
});
server.listen(3000);

$generalHealthState = app('pragmarx.health')->checkResources();
// or
$databaseHealthy = app('pragmarx.health')->checkResource('database')->isHealthy();
Checking in artisan commands example:
Artisan::command('database:health', function () {
app('pragmarx.health')->checkResource('database')->isHealthy()
? $this->info('database is healthy')
: $this->info('database is in trouble')
;
})->describe('Check database health');
As the SensioLabs Security Checker package was abandoned, this checker now depends on local-php-security-checker. You need to compile or install it on your server or container in order to use this checker, and update the config/resources/SecurityChecker.yml
file accordingly.
To use it on Lumen, you'll probably need to do something like this on your bootstrap/app.php
:
$app->instance('path.config', app()->basePath() . DIRECTORY_SEPARATOR . 'config');
$app->instance('path.storage', app()->basePath() . DIRECTORY_SEPARATOR . 'storage');
$app->withFacades();
$app->singleton('Illuminate\Contracts\Routing\ResponseFactory', function ($app) {
return new \Illuminate\Routing\ResponseFactory(
$app['Illuminate\Contracts\View\Factory'],
$app['Illuminate\Routing\Redirector']
);
});
$app->register(PragmaRX\Health\ServiceProvider::class);
$ composer test
