This package is a Laravel wrapper for the influxdb-php client. We utilise graham-campbell/manager to provide multiple connection interfaces.
This package requires PHP 7.4+, Laravel 8+ and works with InfluxDB 2.0/1.8+. For InfluxDB 1.7 or earlier, see the 1.x setup instructions in the next section.
-
To install the latest version of the package, run the following command in your terminal:
$ composer require ge-tracker/influxdb-laravel
Laravel will auto-discover the package's service provider, located at
GeTracker\InfluxDBLaravel\InfluxDBLaravelServiceProvider. -
Next, you should publish the application's configuration file
$ php artisan vendor:publish
To install a 1.7x compatible version, please install version 1.x of this package. You can view the 1.x configuration options on GitHub.
$ composer require "ge-tracker/influxdb-laravel:^1.0"This package's configuration, after publishing, will be located at config/influxdb.php.
Default Connection Name
This option ('default') is where you may specify which of the connections below you wish to use as your default connection for all work. Of course, you may use many connections at once using the manager class. The default value for this setting is 'main'.
InfluxDB Connections
This option ('connections') is where each of the connections are setup for your application. An example configuration has been included, but you may add as many connections as you would like.
The underlying InfluxDB connection instance can be accessed via Facade or Dependency Injection. Unless specified, the package will use the main connection by default.
Facade
<?php
// create an array of points
$points = [
new InfluxDB\Point(
'test_metric', // name of the measurement
null, // the measurement value
['host' => 'server01', 'region' => 'us-west'], // optional tags
['cpucount' => 10], // optional additional fields
time() // Time precision has to be set to seconds!
),
new InfluxDB\Point(
'test_metric', // name of the measurement
null, // the measurement value
['host' => 'server01', 'region' => 'us-west'], // optional tags
['cpucount' => 10], // optional additional fields
time() // Time precision has to be set to seconds!
)
];
$result = InfluxDB::writePoints($points, \InfluxDB\Database::PRECISION_SECONDS);Dependency Injection
DI can be used by type-hinting the InfluxDBManager class:
<?php
namespace App;
use GeTracker\InfluxDBLaravel\InfluxDBManager;
class Foo
{
public function __construct(
protected InfluxDBManager $influxDb
) {
$this->influxDB = $influxDB;
}
public function bar()
{
return $this->influxDb->getQueryBuilder()
->select('usage, idle')
->from('cpu')
->where([
'time < now() -1d',
"host='host01'",
])
->getResultSet();
}
}Both the InfluxDBManager and InfluxDB facade provide a connection() method, which will allow another InfluxDB connection to be interacted with:
// The `main` connection will be used
$manager->query("SELECT * FROM cpu");
// The `alternative` connection will be used
$manager->connection('alternative')->query("SELECT * FROM cpu");
