+Plugin: go.d.plugin
+Module: powerdns_recursor
+
+<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
+
+## Overview
+
+This collector monitors PowerDNS Recursor instances.
+
+It collects metrics from [the internal webserver](https://doc.powerdns.com/recursor/http-api/index.html#built-in-webserver-and-http-api).
+
+Used endpoints:
+
+- [`/api/v1/servers/localhost/statistics`](https://doc.powerdns.com/recursor/common/api/endpoint-statistics.html)
+
+
+
+
+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 PowerDNS Recursor instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| powerdns_recursor.questions_in | total, tcp, ipv6 | questions/s |
+| powerdns_recursor.questions_out | udp, tcp, ipv6, throttled | questions/s |
+| powerdns_recursor.answer_time | 0-1ms, 1-10ms, 10-100ms, 100-1000ms, slow | queries/s |
+| powerdns_recursor.timeouts | total, ipv4, ipv6 | timeouts/s |
+| powerdns_recursor.drops | over-capacity-drops, query-pipe-full-drops, too-old-drops, truncated-drops, empty-queries | drops/s |
+| powerdns_recursor.cache_usage | cache-hits, cache-misses, packet-cache-hits, packet-cache-misses | events/s |
+| powerdns_recursor.cache_size | cache, packet-cache, negative-cache | entries |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+#### Enable webserver
+
+Follow [webserver](https://doc.powerdns.com/recursor/http-api/index.html#webserver) documentation.
+
+
+#### Enable HTTP API
+
+Follow [HTTP API](https://doc.powerdns.com/recursor/http-api/index.html#enabling-the-api) documentation.
+
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `go.d/powerdns_recursor.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/powerdns_recursor.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. | 5 | no |
+| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no |
+| url | Server URL. | http://127.0.0.1:8081 | yes |
+| timeout | HTTP request timeout. | 1 | no |
+| username | Username for basic HTTP authentication. | | no |
+| password | Password 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
+
+To troubleshoot issues with the `powerdns_recursor` 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 powerdns_recursor
+ ```
+
