Extremely Useful

I have been using PeakHour for quite a while and it only keeps getting better. I’ve always used it with devices that support SNMP, however, I recently needed to switch to a different router that doesn’t support SNMP (Linksys X2000), and PeakHour found it via UPNP and displays the stats perfectly, which is a miracle considering all the complaints about that router.

The power of this application is that you get instant visiblity into network performance. If you want long term history, there are other tools that can do a 1min or 5min resolution. However, when you want 0.5 second resolution, this is the go-to tool.

I have pointed this as a large number of devices (home, small office, and enterprise class) and device types (routers, firewalls, servers) and have had no issues that weren’t either that the device didn’t support snmp, had snmp misconfigured, or were doing something completely non-standard (not using standard MIBs).

As the description points out, use the compatabilty tool to make sure your hardware works if you’re concerned it won’t.

Great utility - could use some work though!

This utility is great to get instant insight into my total WAN usage. I use the stock firmware on my Netgear 3500L and it’s great to be able to track it via UPNP without having to flash DD-WRT (yuck!) on it.

It also supports SNMP which allows me to track my remote targets on the racks in the colo. The biggest drawback is that the interfaces in my servers and network gear have a 60 second polling time while my home router can be polled every 0.5 seconds. I do have dedicated monitoring applications for the rack, but it would be really great if this utility is able to independently set refresh rate on each target.

Great App

I have been using this app for over a year. Not sure why all the negative reviews, as it easily connected to AirPort express and displays in/outbound traffic very nicely.
