Issues using this role with Telegraf v1.11.0

[wdschei]

My team uses this Ansible Role as part of our performance test suite and we started failing as soon as Telegraf v1.11.0 was released.

We have started the investigation as to what is the root cause, but our short term fix has been to set telegraf_install_url to the previous version.

Is anyone else seeing anything like this:

I came to the same problem today, the hint was in the logs:

Jun 24 16:17:10 xxx telegraf[19525]: 2019-06-24T14:17:10Z I! Starting Telegraf 1.11.0
Jun 24 16:17:10 xxx telegraf[19525]: 2019-06-24T14:17:10Z E! [telegraf] Error running agent: Error parsing /etc/telegraf/telegraf.conf, line 110: field corresponding to `mount_points' in disk.DiskStats cannot be set through TOML

The error is an regression from 1.11.0: https://github.com/influxdata/telegraf/pull/5982

It has been solved in telegraf code already, just not released yet.
