+
+## Overview
+
+This collector monitors RiakKV metrics about throughput, latency, resources and more.'
+
+
+This collector reads the database stats from the `/stats` endpoint.
+
+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
+
+If the /stats endpoint is accessible, RiakKV instances on the local host running on port 8098 will be autodetected.
+
+#### 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 RiakKV instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| riak.kv.throughput | gets, puts | operations/s |
+| riak.dt.vnode_updates | counters, sets, maps | operations/s |

+
+
+## Setup
+
+### Prerequisites
+
+#### Configure RiakKV to enable /stats endpoint
+
+You can follow the RiakKV configuration reference documentation for how to enable this.
+
+Source : https://docs.riak.com/riak/kv/2.2.3/configuring/reference/#client-interfaces
+
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `python.d/riakkv.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config python.d/riakkv.conf
+```
+#### Options
+
+There are 2 sections:
+
+* Global variables
+* One or more JOBS that can define multiple different instances to monitor.
+
+The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
+
+Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
+
+Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
+
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Sets the default data collection frequency. | 5 | no |
+| priority | Controls the order of charts at the netdata dashboard. | 60000 | no |
+| autodetection_retry | Sets the job re-check interval in seconds. | 0 | no |
+| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | no |
+| url | The url of the server | no | yes |
+
+</details>
+
+#### Examples
+
+##### Basic (default)
+
+A basic example configuration per job
+
+```yaml
+local:
+url: 'http://localhost:8098/stats'
+
+```
+##### Multi-instance
+
+> **Note**: When you define multiple jobs, their names must be unique.
+
+Collecting metrics from local and remote instances.

+
+remote:

+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `riakkv` collector, run the `python.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 `python.d.plugin` to debug the collector:
+
+  ```bash
+  ./python.d.plugin riakkv debug trace
+  ```
+
