#Example of a PowerShell external collector. See http://bosun.org/scollector/external-collectors for details
#This file should be saved in C:\Program Files\scollector\collectors\0\mymetrics.ps1 since it is a continuous output script

#If a continuous output script ever exits scollector will restart it. If you just want periodic data every 60 seconds you
#can use a /60/ folder instead of /0/ and allow the script to exit when finished sending a batch of metrics.
