[damm]

Bug report

Relevant telegraf.conf:

[inputs.ping]]
urls = ["ipv4.google.com","ipv6.l.google.com"]

System info:

Gentoo Linux; using linux tarball/gz 1.3.0

Steps to reproduce:

1. ...Install Telegraf
   2 ...On an ipv6 enabled host configure the ping plugin to ping ipv6 hosts

Expected behavior:

It to return an address and ping it and store the results.

Actual behavior:

It fails to return an address. Chonograf shows this host but returns no data.

pinging ipv6 on linux requires ping6 binary, which (it seems) not supported in telegraf ATM.

Sometimes it requires ping6 but it depends on the system, we are tracking support for ipv6 on #2159 so I'm going to close this issue.

@rlex it worked previously? so what changed?

@danielnelson doesn't seem that helpful of a response there. As it worked previously and stopped working now; I assume something in telegraf changed.

ipv6 has been working natively for me for almost a year; I'll be quite honest my Gentoo is older than it should be and the ping6 binary hasn't been touched in that time. (Yeah I'm sure my coreutils is dated) but that shouldn't matter as it's returning -2 which kinda makes me think it's running the wrong binary

Lastly I have ping6; thanks for the other issue but I will comment this update is rather unsatisfying. It worked; it doesn't now; yeah very unsatisfying excuses.

Can you add the output of running ping ipv6.l.google.com?
