statsd - protocol not a supported config field

[tshchensek]

Hi,

I'm running into an error where I can't specify protocol in statsd.conf plugin. Fortunately, for my use case, the default UDP is what I need, but that still goes against the documentation: https://github.com/influxdata/telegraf/tree/master/plugins/inputs/statsd#configuration. Is it a version issue?

Thanks

Relevant telegraf.conf:

$ cat /etc/telegraf/telegraf.d/statsd.conf 
[[inputs.statsd]]
  allowed_pending_messages = 1000
  delete_counters = true
  delete_gauges = true
  delete_sets = true
  delete_timings = true
  metric_separator = "_"
  parse_data_dog_tags = false
  percentile_limit = 1000
  percentiles = [50, 90, 95, 99]
  protocol = "udp"
  service_address = "localhost:8125"

System info:

$ uname -a
Linux 4.4.0-64-generic #85-Ubuntu SMP Mon Feb 20 11:50:30 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ telegraf -version
Telegraf v1.1.1 (git: release-1.1.0 94de9dc)

Steps to reproduce:

1. sudo service telegraf start

Expected behavior:

sudo service telegraf status returns with "running"

Actual behavior:

sudo service telegraf status returns with

May 14 18:44:02 <hostname> systemd[1]: telegraf.service: Main process exited, code=exited, status=1/FAILURE
May 14 18:44:02 <hostname> systemd[1]: telegraf.service: Unit entered failed state.

This option was added in a later version of Telegraf (I believe 1.4) than you are using.

@danielnelson, thanks. How can I find the current version from the github repo? Also, do you know in which github revision I can find documentation that pertains to 1.1?

[danielnelson]

Your best bet is to look at the release tags, you can follow links from this page to get to the tree for that version, or just go to URLs like:

• https://github.com/influxdata/telegraf/tree/1.6.2
• https://github.com/influxdata/telegraf/tree/1.1.1
