Hi, Jacob.

We cover some general concepts about long term monitoring here:

That might give you some general direction.

As for your specific questions:

1) No - the web interface for PingPlotter Pro is entirely independant of the auto-save settings.

2) No - The max samples in memory setting in the Options screen is used for setting the memory footprint. The # of times to trace in the main screen is only used to determine how many samples will be done. This is almost always set to 0 - and for long term monitoring, should always be 0 (ALL). The Max samples in memory, though, should be set to something different - see the knowledge base article referenced above for more details on this.

3) All settings are per-host. If you want 100 samples for each one, you'd set it to 100.

4) It's saved at the specified time. We normally save data every 30 minutes, but recommend having at least a day's worth of data in memory. The important thing is that you need a "bucket" to save things in - and the bucket size if determined by the file name - if it only has a date in it, then you only get one bucket a day and you'll need to have enough in memory to fill that bucket. If your file name has $hour in it, you'll get a save file per hour, and you'll want to make your max samples in memory be at least an hour's worth (3600).

Have a look over the article referenced above and then feel free to come back with any questions.
