Frequently Asked Questions (FAQ):

Q:  “What are the system requirements for Network Logger Pro?”

A:  Currently Network Logger Pro requires OSX 10.7 “Lion” as a minimum and has been verified to work with macOS 10.12 “Sierra.”

Q:  “We have recently moved to a new internet provider and are finding recurring, but inconsistent internet service periods “randomly” (it seems) – we lose our connection for 1 to 4 minutes and then it magically restores itself. We’ve had the ISP replace the router/modem, check the line on their end, etc.  I’m looking for an Internet Monitoring tool that I can run for a day or two that will continuously check the connection (to the primary DNS server?) and log “outages” so that I can “prove” to the ISP that it’s occurring, and when /how long outages occur. …  Will your tool meet our needs, or do you know of a tool that will fulfill these needs?”

A:  Yes, logging outages over arbitrary periods is one of Network Logger Pro’s features.

Q:  “Does Network Logger Pro use a lot of CPU time?”

A:  Since Network Logger Pro is designed to run for weeks or months at a time, a lot of care has gone into designing it to use very little CPU time.  That way your machine stays cool and has almost all of it’s power available for other tasks.  Typical usage with the default settings is about 5% of one core.  It will use less on newer machines.

Q:  “Since using your Network Logging Pro I am getting reports from the 3rd party monitoring company that your application is trying to contact a number of web sites for an unknown reason.  Can you explain why this is happening?”

That is a feature called Automatic Connection Testing, which does connection outage logging.  You can see that activity in the ACT Activity window, under the Window menu.  It’s not pulling data down, it’s seeing if it can reach the servers via ping and http header requests.   If you want to turn it off you can do so in the Preferences by setting the Automatic Connection Testing Interval to Off.  In that case if you still want outage logging you’ll have to set up your own Server Monitor from the File menu.  More details can be found in the User Manual under the Help menu in the menubar.

Q:  “Why doesn’t my URL work in the Server Monitor?”

A:  Make sure your URLs is not malformed, meaning they contain spaces or other characters that don’t conform to the URL standard.  If your URL works in a browser, simply copy it from the browser’s URL field and paste it into Network Logger Pro.

Q: “My internet drops out quite often but usually only for a few seconds, would your logger note these short periods?”

A:  Yes, but it would be unusual to have actual disconnects that behave like that.  Usually when you see that kind of behavior, either network bandwidth is fully utilized momentarily or a server is very busy, neither is really an outage but the former can cause some services to disconnect, like VPN, FTP, or IRC, because too many packets are dropped.
