Installation

The preferred way to install this extension is through composer.

composer require --prefer-dist machour/yii2-prometheus

Configuration

In order to exploit the metrics files generated by this extension, you must run the node exporter using the --collector.textfile.directory flag, and point it to a valid directory.

If using systemd to manage your scrappers, your node_exporter.service file may look something like this:

node_exporter.service
[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target

[Service]
User=prometheus
ExecStart=/usr/local/bin/node_exporter --collector.textfile.directory /var/lib/node_exporter/textfile_collector  --web.listen-address="127.0.0.1:9100"

[Install]
WantedBy=default.target

Once the extension is installed, simply modify your application configuration as follows:

return [
    'components' => [
        'prometheusExporter' => [
            'class' => 'machour\yii2\prometheus\components\Exporter',
            
            // Point this to your collector directory. Defaults to '/var/lib/node_exporter/textfile_collector/'
            // 'collectorDir' => '/var/lib/node_exporter/textfile_collector/',
            
            // The default prom file to create if not specified in exportMetric()
            // 'defaultFile' => 'yii2-prometheus-exporter.prom',
        ],
        // ...
    ],
    ...
];
