Plugin: go.d.plugin Module: phpdaemon


This collector monitors phpDaemon instances.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior


This integration doesn’t support auto-detection.


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



Enable phpDaemon’s HTTP server

Statistics expected to be in JSON format.

phpDaemon configuration

Instruction from @METAJIJI.

To 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 {
    listen '';
    port 8509;
// /opt/phpdaemon/conf/AppResolver.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;

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

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);



The configuration file name for this integration is go.d/phpdaemon.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/phpdaemon.conf


The following options can be defined globally: update_every, autodetection_retry.

Name Description Default Required
update_every Data collection frequency. 1 False
autodetection_retry Recheck interval in seconds. Zero means no recheck will be scheduled. 0 False
url Server URL. True
timeout HTTP request timeout. 2 False
username Username for basic HTTP authentication. False
password Password for basic HTTP authentication. False
proxy_url Proxy URL. False
proxy_username Username for proxy basic HTTP authentication. False
proxy_password Password for proxy basic HTTP authentication. False
method HTTP request method. GET False
body HTTP request body. False
headers HTTP request headers. False
not_follow_redirects Redirect handling policy. Controls whether the client follows redirects. False False
tls_skip_verify Server certificate chain and hostname validation policy. Controls whether the client performs this check. False False
tls_ca Certification authority that the client uses when verifying the server’s certificates. False
tls_cert Client TLS certificate. False
tls_key Client TLS key. False



A basic example configuration.

  - name: local

HTTP authentication

HTTP authentication.

  - name: local
    username: username
    password: password

HTTPS with self-signed certificate

HTTPS with self-signed certificate.

  - name: local
    tls_skip_verify: yes


Note: When you define multiple jobs, their names must be unique.

Collecting metrics from local and remote instances.

  - name: local

  - name: remote


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per phpDaemon instance

These metrics refer to the entire monitored application.

This scope has no labels.


Metric Dimensions Unit
phpdaemon.workers alive, shutdown workers
phpdaemon.alive_workers idle, busy, reloading workers
phpdaemon.idle_workers preinit, init, initialized workers
phpdaemon.uptime time seconds


There are no alerts configured by default for this integration.


Debug Mode

To troubleshoot issues with the phpdaemon collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn’t working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that’s not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

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