NSQ plugin not compatible with latest release

[ashtonian]

Bug report

The nsq input plugin uses the /stats http endpoint which has changed its format in March.

Relevant telegraf.conf:

Used the following to generate the config.

./telegraf --output-filter nsq config

System info:

Telegraf: latest, OSX

Steps to reproduce:

1. Run local instance of NSQ - docker run --name nsqd -p 4150:4150 -p 4151:4151 nsqio/nsq nsqd More info: http://nsq.io/overview/quick_start.html
2. Publish test message with curl -d 'hello world 1' 'http://127.0.0.1:4151/pub?topic=test'
3. Verify http://localhost:4151/stats?format=json returns data. This is the endpoint telegraf uses.
4. Run telegraf in test mode with generated config ./telegraf --config telegraf.conf --test

Expected behavior:

Telegraf to report Topic/Client/Channel stats

Actual behavior:

Telegraf reports 0 topics.

Additional info:

This seems to have been caused by changes in the latest release - https://github.com/nsqio/nsq/releases/tag/v1.0.0-compat

This will break functionality for nsq versions < 1.0.
