Windows Perfmon Counters Not Detected

[fenneh]

This isn't necessarily a bug - maybe an oversight.

Bug report

If Telegraf starts up before an application has started publishing its own performance counters then they are never detected and no metrics are sent. A restart of the Telegraf agent is then required.

System info:

Windows Server 2008R2, 2012R2. Telegraf 1.4.0.

Steps to reproduce:

1. Start Telegraf Agent
2. Start Windows App which publishes to perfmon
3. No perfmon capture

Expected behavior:

Perfmon counters will be picked up and shipped

Actual behavior:

No perfmon counters detected

Feature Request

Either allow telegraf to reload it's config from disk on a set period or allow telegraf to re-evaluate its own config every X minutes

Same issue on Windows 10 x64 (not for all, just for some)

KeepAlive = true
doesn't support v 1.4.1 and nightly build too

@fenneh @andryua This may have been addressed by #4189, would it be possible for you to retest the issue using the nightly builds?

[fenneh]

Testing it out now @danielnelson - Will close the issue off if all is well.
