 ## v0.10.3 [unreleased]

 ### Release Notes
+- Users of the `exec` and `kafka_consumer` (and the new `nats_consumer`
+and `mqtt_consumer` plugins) can now specify the incoming data
+format that they would like to parse. Currently supports: "json", "influx", and
+"graphite"
+- Users of message broker and file output plugins can now choose what data format
+they would like to output. Currently supports: "influx" and "graphite"
+- More info on parsing _incoming_ data formats can be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md)
+- More info on serializing _outgoing_ data formats can be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
+- Telegraf now has an option `flush_buffer_when_full` that will flush the
+metric buffer whenever it fills up for each output, rather than dropping
+points and only flushing on a set time interval. This will default to `true`
+and is in the `[agent]` config section.

-### Accumulator
-
-The way that a plugin emits metrics is by interacting with the Accumulator.
-
-The `Add` function takes 3 arguments:
-* **measurement**: A string description of the metric. For instance `bytes_read` or `
-faults`.
-* **value**: A value for the metric. This accepts 5 different types of value:
-  * **int**: The most common type. All int types are accepted but favor using `int64`
-  Useful for counters, etc.
-  * **float**: Favor `float64`, useful for gauges, percentages, etc.
-  * **bool**: `true` or `false`, useful to indicate the presence of a state. `light_on`,
-  etc.
-  * **string**: Typically used to indicate a message, or some kind of freeform
-  information.
-  * **time.Time**: Useful for indicating when a state last occurred, for instance `
-  light_on_since`.
-* **tags**: This is a map of strings to strings to describe the where or who
-about the metric. For instance, the `net` plugin adds a tag named `"interface"`
-set to the name of the network interface, like `"eth0"`.

+## Input Plugins Accepting Arbitrary Data Formats
+
+Some input plugins (such as
+[exec](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/exec))
+accept arbitrary input data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+In order to enable this, you must specify a `SetParser(parser parsers.Parser)`
+function on the plugin object (see the exec plugin for an example), as well as
+defining `parser` as a field of the object.
+
+You can then utilize the parser internally in your plugin, parsing data as you
+see fit. Telegraf's configuration layer will take care of instantiating and
+creating the `Parser` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to consume. This can be "json", "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+Below is the `Parser` interface.
+
+```go
+// Parser is an interface defining functions that a parser plugin must satisfy.
+type Parser interface {
+    // Parse takes a byte buffer separated by newlines
+    // ie, `cpu.usage.idle 90\ncpu.usage.busy 10`
+    // and parses it into telegraf metrics
+    Parse(buf []byte) ([]telegraf.Metric, error)

+    // ParseLine takes a single string metric
+    // ie, "cpu.usage.idle 90"
+    // and parses it into a telegraf metric.

+# Telegraf Input Data Formats
+
+Telegraf metrics, like InfluxDB
+[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
+are a combination of four basic parts:
+
+1. Measurement Name
+1. Tags
+1. Fields
+1. Timestamp
+
+These four parts are easily defined when using InfluxDB line-protocol as a
+data format. But there are other data formats that users may want to use which
+require more advanced configuration to create usable Telegraf metrics.
+
+Plugins such as `exec` and `kafka_consumer` parse textual data. Up until now,
+these plugins were statically configured to parse just a single
+data format. `exec` mostly only supported parsing JSON, and `kafka_consumer` only
+supported data in InfluxDB line-protocol.
+
+But now we are normalizing the parsing of various data formats across all
+plugins that can support it. You will be able to identify a plugin that supports
+different data formats by the presence of a `data_format` config option, for
+example, in the exec plugin:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume. This can be "json", "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## Additional configuration options go here
+```
+
+Each data_format has an additional set of configuration options available, which
+I'll go over below.
+
+## Influx:
+
+There are no additional configuration options for InfluxDB line-protocol. The
+metrics are parsed directly into Telegraf metrics.
+
+#### Influx Configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume. This can be "json", "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+## JSON:
+
+The JSON data format flattens JSON into metric _fields_. For example, this JSON:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    }
+}
+```
+
+Would get translated into _fields_ of a measurement:
+
+```
+myjsonmetric a=5,b_c=6
+```
+
+The _measurement_ _name_ is usually the name of the plugin,
+but can be overridden using the `name_override` config option.
+
+#### JSON Configuration:
+
+The JSON data format supports specifying "tag keys". If specified, keys
+will be searched for in the root-level of the JSON blob. If the key(s) exist,
+they will be applied as tags to the Telegraf metrics.
+
+For example, if you had this configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume. This can be "json", "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## List of tag names to extract from top-level of JSON server response
+  tag_keys = [
+    "my_tag_1",
+    "my_tag_2"
+  ]
+```
+
+with this JSON output from a command:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    },
+    "my_tag_1": "foo"
+}
+```
+
+Your Telegraf metrics would get tagged with "my_tag_1"
+
+```
+exec_mycollector,my_tag_1=foo a=5,b_c=6
+```
+
+## Graphite:
+
+The Graphite data format translates graphite _dot_ buckets directly into
+telegraf measurement names, with a single value field, and without any tags. For
+more advanced options, Telegraf supports specifying "templates" to translate
+graphite buckets into Telegraf metrics.
+
+#### Separator:
+
+You can specify a separator to use for the parsed metrics.
+By default, it will leave the metrics with a "." separator.
+Setting `separator = "_"` will translate:
+
+```
+cpu.usage.idle 99
+=> cpu_usage_idle value=99
+```
+
+#### Measurement/Tag Templates:
+
+The most basic template is to specify a single transformation to apply to all
+incoming metrics. _measurement_ is a special keyword that tells Telegraf which
+parts of the graphite bucket to combine into the measurement name. It can have a
+trailing `*` to indicate that the remainder of the metric should be used.
+Other words are considered tag keys. So the following template:
+
+```toml
+templates = [
+    "region.measurement*"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+us-west.cpu.load 100
+=> cpu.load,region=us-west value=100
+```
+
+#### Field Templates:
+
+There is also a _field_ keyword, which can only be specified once.
+The field keyword tells Telegraf to give the metric that field name.
+So the following template:
+
+```toml
+templates = [
+    "measurement.measurement.field.region"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.us-west 100
+=> cpu_usage,region=us-west idle=100
+```
+
+#### Filter Templates:
+
+Users can also filter the template(s) to use based on the name of the bucket,
+using glob matching, like so:
+
+```toml
+templates = [
+    "cpu.* measurement.measurement.region",
+    "mem.* measurement.measurement.host"
+]
+```
+
+which would result in the following transformation:
+
+```
+cpu.load.us-west 100
+=> cpu_load,region=us-west value=100
+
+mem.cached.localhost 256
+=> mem_cached,host=localhost value=256
+```
+
+#### Adding Tags:
+
+Additional tags can be added to a metric that don't exist on the received metric.
+You can add additional tags by specifying them after the pattern.
+Tags have the same format as the line protocol.
+Multiple tags are separated by commas.
+
+```toml
+templates = [
+    "measurement.measurement.field.region datacenter=1a"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.us-west 100
+=> cpu_usage,region=us-west,datacenter=1a idle=100
+```
+
+There are many more options available,
+[More details can be found here](https://github.com/influxdata/influxdb/tree/master/services/graphite#templates)
+
+#### Graphite Configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume. This can be "json", "influx" or "graphite" (line-protocol)
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "graphite"
+
+  ## This string will be used to join the matched values.
+  separator = "_"
+
+  ## Each template line requires a template pattern. It can have an optional
+  ## filter before the template and separated by spaces. It can also have optional extra
+  ## tags following the template. Multiple tags should be separated by commas and no spaces
+  ## similar to the line protocol format. There can be only one default template.
+  ## Templates support below format:
+  ## 1. filter + template
+  ## 2. filter + template + extra tag
+  ## 3. filter + template with field key
+  ## 4. default template
+  templates = [
+    "*.app env.service.resource.measurement",
+    "stats.* .host.measurement* region=us-west,agent=sensu",
+    "stats2.* .host.measurement.field",
+    "measurement*"

+# Telegraf Output Data Formats
+
+Telegraf metrics, like InfluxDB
+[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
+are a combination of four basic parts:
+
+1. Measurement Name
+1. Tags
+1. Fields
+1. Timestamp
+
+In InfluxDB line protocol, these 4 parts are easily defined in textual form:
+
+```
+measurement_name[,tag1=val1,...]  field1=val1[,field2=val2,...]  [timestamp]
+```
+
+For Telegraf outputs that write textual data (such as `kafka`, `mqtt`, and `file`),
+InfluxDB line protocol was originally the only available output format. But now
+we are normalizing telegraf metric "serializers" into a
+[plugin-like interface](https://github.com/influxdata/telegraf/tree/master/plugins/serializers)
+across all output plugins that can support it.
+You will be able to identify a plugin that supports different data formats
+by the presence of a `data_format`
+config option, for example, in the `file` output plugin:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout"]
+
+  ## Data format to output. This can be "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read

+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```
+
+## Graphite:
+
+The Graphite data format translates Telegraf metrics into _dot_ buckets.
+The format is:
+
+```
+[prefix].[host tag].[all tags (alphabetical)].[measurement name].[field name] value timestamp
+```
+
+Which means the following influx metric -> graphite conversion would happen:
+
+```
+cpu,cpu=cpu-total,dc=us-east-1,host=tars usage_idle=98.09,usage_user=0.89 1455320660004257758

+tars.cpu-total.us-east-1.cpu.usage_idle 98.09 1455320690
+```
+
+`prefix` is a configuration option when using the graphite output data format.

+# MQTT Consumer Input Plugin
+
+The [MQTT](http://mqtt.org/) consumer plugin reads from
+specified MQTT topics and adds messages to InfluxDB.
+The plugin expects messages in the
+[Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+### Configuration:
+
+```toml
+# Read metrics from MQTT topic(s)
+[[inputs.mqtt_consumer]]
+  servers = ["localhost:1883"]
+  ## MQTT QoS, must be 0, 1, or 2
+  qos = 0
+
+  ## Topics to subscribe to
+  topics = [
+    "telegraf/host01/cpu",
+    "telegraf/+/mem",
+    "sensors/#",
+  ]
+
+  ## Maximum number of metrics to buffer between collection intervals
+  metric_buffer = 100000
+
+  ## username and password to connect MQTT server.
+  # username = "telegraf"
+  # password = "metricsmetricsmetricsmetrics"
+
+  ## Optional SSL Config
+  # ssl_ca = "/etc/telegraf/ca.pem"
+  # ssl_cert = "/etc/telegraf/cert.pem"
+  # ssl_key = "/etc/telegraf/key.pem"
+  ## Use SSL but skip chain & host verification
+  # insecure_skip_verify = false
+
+  ## Data format to consume. This can be "json", "influx" or "graphite"

+# NATS Consumer Input Plugin
+
+The [NATS](http://www.nats.io/about/) consumer plugin reads from
+specified NATS subjects and adds messages to InfluxDB. The plugin expects messages
+in the [Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+A [Queue Group](http://www.nats.io/documentation/concepts/nats-queueing/)
+is used when subscribing to subjects so multiple instances of telegraf can read
+from a NATS cluster in parallel.
+
+## Configuration
+
+```toml
+# Read metrics from NATS subject(s)
+[[inputs.nats_consumer]]
+  ## urls of NATS servers
+  servers = ["nats://localhost:4222"]
+  ## Use Transport Layer Security
+  secure = false
+  ## subject(s) to consume
+  subjects = ["telegraf"]
+  ## name a queue group
+  queue_group = "telegraf_consumers"
+  ## Maximum number of metrics to buffer between collection intervals
+  metric_buffer = 100000
+
+  ## Data format to consume. This can be "json", "influx" or "graphite"
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
