This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. This integration doesn't support auto-detection. The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. These metrics refer to the entire monitored application. This scope has no labels. Metrics: | 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. Statistics expected to be in JSON format. <details> <summary>phpDaemon configuration</summary> Instruction from . To enable `phpd` statistics on http, you must enable the http server and write an application. Application is important, because standalone application provides statistics in html format and unusable for `netdata`. ```php // /opt/phpdaemon/conf/phpd.conf path /opt/phpdaemon/conf/AppResolver.php; Pool:HTTPServer { privileged; listen '127.0.0.1'; port 8509; } ``` ```php // /opt/phpdaemon/conf/AppResolver.php <?php class MyAppResolver extends \PHPDaemon\Core\AppResolver { public function getRequestRoute($req, $upstream) { if (pregmatch('~^/(ServerStatus|FullStatus)/~', $req->attrs->server['DOCUMENTURI'], $m)) { return $m[1]; } } } return new MyAppResolver; ``` ```php /opt/phpdaemon/conf/PHPDaemon/Applications/FullStatus.php <?php namespace PHPDaemon\Applications; class FullStatus extends \PHPDaemon\Core\AppInstance { public function beginRequest($req, $upstream) { return new FullStatusRequest($this, $upstream, $req); } } ``` ```php // /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); } } ``` </details> 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 . ```bash 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: updateevery,

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]`. ```bash cd /usr/libexec/netdata/plugins.d/ ``` Switch to the `netdata` user. ```bash sudo -u netdata -s ``` Run the `go.d.plugin` to debug the collector: ```bash ./go.d.plugin -d -m phpdaemon ```
