Phpdaemon monitoring with Netdata

phpdaemon is an asynchronous server-side framework for Web and network applications implemented in PHP using libevent.

This module collects phpdaemon workers statistics via http.

Requirements

  • phpdaemon with enabled http server.
  • statistics should be reported in json format.

Charts

It produces the following charts:

  • Workers in workers
  • Alive Workers State in workers
  • Idle Workers State in workers
  • Uptime in seconds

Configuration

Edit the go.d/phpdaemon.conf configuration file using edit-config from the your agent’s config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/phpdaemon.conf

Here is an example for 2 instances:

jobs:
  - name: local
    url : http://127.0.0.1:8509/FullStatus

  - name: remote
    url : http://10.0.0.1:8509/FullStatus

For all available options please see module configuration file.

Instruction from @METAJIJI

For enable phpd statistics on http, you must enable the http server and write an application.

Application is important, because standalone application ServerStatus.php provides statistics in html format and unusable for netdata.

/opt/phpdaemon/conf/phpd.conf

path /opt/phpdaemon/conf/AppResolver.php;
Pool:HTTPServer {
    privileged;
    listen '127.0.0.1';
    port 8509;
}

/opt/phpdaemon/conf/AppResolver.php

<?php

class MyAppResolver extends \PHPDaemon\Core\AppResolver {
    public function getRequestRoute($req, $upstream) {
        if (preg_match('~^/(ServerStatus|FullStatus)/~', $req->attrs->server['DOCUMENT_URI'], $m)) {
            return $m[1];
        }
    }
}

return new MyAppResolver;

/opt/phpdaemon/conf/PHPDaemon/Applications/FullStatus.php

<?php
namespace PHPDaemon\Applications;

class FullStatus extends \PHPDaemon\Core\AppInstance {
    public function beginRequest($req, $upstream) {
        return new FullStatusRequest($this, $upstream, $req);
    }
}

/opt/phpdaemon/conf/PHPDaemon/Applications/FullStatusRequest.php

<?php
namespace PHPDaemon\Applications;

use PHPDaemon\Core\Daemon;
use PHPDaemon\HTTPRequest\Generic;

class FullStatusRequest extends Generic {
    public function run() {
        $stime = microtime(true);
        $this->header('Content-Type: application/javascript; charset=utf-8');

        $stat = Daemon::getStateOfWorkers();
        $stat['uptime'] = time() - Daemon::$startTime;
        echo json_encode($stat);
    }
}

Troubleshooting

Check the module debug output. Run the following command as netdata user:

./go.d.plugin -d -m phpdaemon
