Simple powershell ping log with timestamp

Here's a quick and dirty script that will ping with a timestamp, and save the ouput to a text file. I have used pingInfoView quite a bit, but sometimes this fits the situation better.

There weren't any indications of dropped traffic in the logs, because default policies are not logged in Palo Alto devices by default, and this traffic was getting denied by the interzone-default policy.

To resolve this easily, just change application-default to any. However, you may want to see what else is being blocked, …
