Need a script or batch to ping across WAN and log results
We have a very relaxed policy WAN between two offices that needs to remain clear of heavy traffic. Every so often I might have an application exceed what it should use and end up slowing everything to a crawl. Unless there is another free solution that somewhere is aware of, I could use a simple script or batch to ping across the WAN (I am able to ping a computer) and then write the findings to a log if the time=>300ms for more than 5 replies (or something similar that could be tweaked). I could then copy the solution and have it check for even worse, say time=>1000 and then use blat to email me the log. The problem now is that I am unaware of any issues until users start complaining about slowness in certain areas. By then it looks bad on me. Thanks for the help!

Sure, this is relatively easy, I will build you a script in the next hour or two.

waiting for my laptop to complete windows updates, I already have the script partially formed in my hrad, itmay be possible to make it a single-line command given enough time, but I will build for batch file instantiation instead.....if...windows 7......will...ever....fini

Great solution! I am testing it tomorrow when at the office. I also would like for it to record the ping results to a log. I actually will be trying to have more than one batch file. The first file would detect smaller delays and just write them consecutive to a local log. I could then have that log emailed to me once a day or even once a week to review a pattern of traffic at a certain time of the day or certain day of the week. This is almost like a simple poor mans way of graphing WAN traffic for analysis.
The second patch, more specific to the one you have created, would detect a much larger problem during the time it is occuring, then emails me a notice. I would have these batches executing several times an hour to get a good sample of the WAN during all hours of the day.

I can certainly create one which does that as well, it's just a bit more complex, and would be a separate Question.
Let me know if there are any issues with the batch I created here; I could not find a slow enough network to run tests with the batch file myself.

Understood. I tested the batch and it seems to stay in a loop, no matter the latency of the WAN. I copied a file across the WAN that slowed the PING to over 1000ms for seveal minutes. Can we have the batch create a log file with each PING so that we can see the results of the test?

Just a note for the contributing Experts:
set /a count += 1
is sufficient. Further you do not need to use % in set /a around a variable.
It's only a nuance, but would you please refrain from using tabs? Two or four spaces are really enough for indention ...
And of course ping -n 5 127.0.0.1 does only wait 4 seconds.

Great work everyone!
VB Script
VBScript (Visual Basic Scripting Edition) is an interpreted scripting language developed by Microsoft that is modeled on Visual Basic, but with some important differences. VBScript is commonly used for automating administrative and other tasks in Windows operating systems (by means of the Windows Script Host) and for server-side scripting in ASP web applications. It is also used for client-side scripting in Internet Explorer, specifically in intranet web applications.
