+
+# Riak KV monitoring with Netdata
+
+Collects database stats from `/stats` endpoint.
+
+## Requirements
+
+- An accessible `/stats` endpoint. See [the Riak KV configuration reference documentation](https://docs.riak.com/riak/kv/2.2.3/configuring/reference/#client-interfaces)
+ for how to enable this.
+
+The following charts are included, which are mostly derived from the metrics
+listed
+[here](https://docs.riak.com/riak/kv/latest/using/reference/statistics-monitoring/index.html#riak-metrics-to-graph).
+
+1. **Throughput** in operations/s
+
+- **KV operations**
+ - gets
+ - puts
+
+- **Data type updates**
+ - counters
+ - sets
+ - maps
+
+- **Search queries**
+ - queries
+
+- **Search documents**
+ - indexed
+
+- **Strong consistency operations**
+ - gets
+ - puts
+
+2. **Latency** in milliseconds
+
+- **KV latency** of the past minute
+ - get (mean, median, 95th / 99th / 100th percentile)
+ - put (mean, median, 95th / 99th / 100th percentile)
+
+- **Data type latency** of the past minute
+ - counter_merge (mean, median, 95th / 99th / 100th percentile)
+ - set_merge (mean, median, 95th / 99th / 100th percentile)
+ - map_merge (mean, median, 95th / 99th / 100th percentile)
+
+- **Search latency** of the past minute
+ - query (median, min, max, 95th / 99th percentile)
+ - index (median, min, max, 95th / 99th percentile)
+
+- **Strong consistency latency** of the past minute
+ - get (mean, median, 95th / 99th / 100th percentile)
+ - put (mean, median, 95th / 99th / 100th percentile)
+
+3. **Erlang VM metrics**
+
+- **System counters**
+ - processes
+
+- **Memory allocation** in MB
+ - processes.allocated
+ - processes.used
+
+4. **General load / health metrics**
+
+- **Siblings encountered in KV operations** during the past minute
+ - get (mean, median, 95th / 99th / 100th percentile)
+
+- **Object size in KV operations** during the past minute in KB
+ - get (mean, median, 95th / 99th / 100th percentile)
+
+- **Message queue length** in unprocessed messages
+ - vnodeq_size (mean, median, 95th / 99th / 100th percentile)
+
+- **Index operations** encountered by Search
+ - errors
+
+- **Protocol buffer connections**
+ - active
+
+- **Repair operations coordinated by this node**
+ - read
+
+- **Active finite state machines by kind**
+ - get
+ - put
+ - secondary_index
+ - list_keys
+
+- **Rejected finite state machines**
+ - get
+ - put
+
+- **Number of writes to Search failed due to bad data format by reason**
+ - bad_entry
+ - extract_fail
+
+## Configuration
+
+Edit the `python.d/riakkv.conf` configuration file using `edit-config` from the Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d/riakkv.conf
+```
+
+The module needs to be passed the full URL to Riak's stats endpoint.
+For example:
+
+```yaml
+myriak:
+ url: http://myriak.example.com:8098/stats
+```
+
+With no explicit configuration given, the module will attempt to connect to
+`http://localhost:8098/stats`.
+
+The default update frequency for the plugin is set to 2 seconds as Riak
+internally updates the metrics every second. If we were to update the metrics
+every second, the resulting graph would contain odd jitter.
+
