+
+## Overview
+
+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
+
+#### Auto-Detection
+
+This integration doesn't support auto-detection.
+
+#### Limits
+
+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.
+
+
+## Metrics
+
+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.
+
+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 |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+#### Enable phpDaemon's HTTP server
+
+Statistics expected to be in JSON format.
+
+<details>
+<summary>phpDaemon configuration</summary>
+
+Instruction from [@METAJIJI](https://github.com/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](https://github.com/kakserpom/phpdaemon/blob/master/PHPDaemon/Applications/ServerStatus.php) 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 (preg_match('~^/(ServerStatus|FullStatus)/~', $req->attrs->server['DOCUMENT_URI'], $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>
+
+
+
+### Configuration
+
+#### File
+
+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](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config go.d/phpdaemon.conf
+```
+#### Options
+
+The following options can be defined globally: update_every, autodetection_retry.
+
+
+<details open><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Data collection frequency. | 1 | no |
+| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no |
+| url | Server URL. | http://127.0.0.1:8509/FullStatus | yes |
+| timeout | HTTP request timeout. | 2 | no |
+| username | Username for basic HTTP authentication. |  | no |

+| proxy_url | Proxy URL. |  | no |
+| proxy_username | Username for proxy basic HTTP authentication. |  | no |
+| proxy_password | Password for proxy basic HTTP authentication. |  | no |
+| method | HTTP request method. | GET | no |
+| body | HTTP request body. |  | no |
+| headers | HTTP request headers. |  | no |
+| not_follow_redirects | Redirect handling policy. Controls whether the client follows redirects. | no | no |
+| tls_skip_verify | Server certificate chain and hostname validation policy. Controls whether the client performs this check. | no | no |
+| tls_ca | Certification authority that the client uses when verifying the server's certificates. |  | no |
+| tls_cert | Client TLS certificate. |  | no |
+| tls_key | Client TLS key. |  | no |

+
+## Troubleshooting
+
+### Debug Mode
+
+**Important**: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
+
+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]`.
+
+  ```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
+  ```
+
+### Getting Logs
+
+If you're encountering problems with the `phpdaemon` collector, follow these steps to retrieve logs and identify potential issues:
+
+- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
+- **Examine the output** for any warnings or error messages that might indicate issues.  These messages should provide clues about the root cause of the problem.
+
+#### System with systemd
+
+Use the following command to view logs generated since the last Netdata service restart:
+
+```bash
+journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep phpdaemon
+```
+
+#### System without systemd
+
+Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
+
+```bash
+grep phpdaemon /var/log/netdata/collector.log
+```
+
+**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.
+
+#### Docker Container
+
+If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
+
+```bash
+docker logs netdata 2>&1 | grep phpdaemon
+```
+
+

+              
+              Instruction from [@METAJIJI](https://github.com/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](https://github.com/kakserpom/phpdaemon/blob/master/PHPDaemon/Applications/ServerStatus.php) provides statistics in html format and unusable for `netdata`.

+              // /opt/phpdaemon/conf/phpd.conf

+                  port 8509;
