* Telegraf v0.10.1+

[Plugin source](https://github.com/influxdata/telegraf/tree/v1.39.0/plugins/inputs/nsq_consumer/)[Download configuration](https://raw.githubusercontent.com/influxdata/telegraf/refs/tags/v1.39.0/plugins/inputs/nsq_consumer/sample.conf)

# NSQ Consumer Input Plugin

This service plugin consumes messages from [NSQ](https://nsq.io/) realtime distributed
messaging platform brokers in one of the supported [data formats](/telegraf/v1/data_formats/input).

**Introduced in:** Telegraf v0.10.1**Tags:** messaging**OS support:** all

## Service Input

This plugin is a service input. Normal plugins gather metrics determined by the
interval setting. Service plugins start a service to listen and wait for
metrics or events to occur. Service plugins have two key differences from
normal plugins:

1. The global or plugin specific `interval` setting may not apply
2. The CLI options of `--test`, `--test-wait`, and `--once` may not produce
   output for this plugin

## Tracking metric support

This plugin supports [tracking metrics](../../../docs/METRICS.md#tracking-metrics), which allows the plugin
to be notified when metrics have been delivered to all outputs, enabling proper
acknowledgment back to the source.

## Global configuration options

Plugins support additional global and plugin configuration settings for tasks
such as modifying metrics, tags, and fields, creating aliases, and configuring
plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# Read metrics from NSQD topic(s)
[[inputs.nsq_consumer]]
  ## An array representing the NSQD TCP HTTP Endpoints
  nsqd = ["localhost:4150"]

  ## An array representing the NSQLookupd HTTP Endpoints
  nsqlookupd = ["localhost:4161"]
  topic = "telegraf"
  channel = "consumer"
  max_in_flight = 100

  ## Max undelivered messages
  ## This plugin uses tracking metrics, which ensure messages are read to
  ## outputs before acknowledging them to the original broker to ensure data
  ## is not lost. This option sets the maximum messages to read from the
  ## broker that have not been written by an output.
  ##
  ## This value needs to be picked with awareness of the agent's
  ## metric_batch_size value as well. Setting max undelivered messages too high
  ## can result in a constant stream of data batches to the output. While
  ## setting it too low may never flush the broker's messages.
  # max_undelivered_messages = 1000

  ## Data format to consume.
  ## Each data format has its 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"
```

## Metrics

The plugin accepts arbitrary input and parses it according to the `data_format`setting. There is no predefined metric format.

## Example Output

There is no predefined metric format, so output depends on plugin input.
