Simplicity is the theme here. We didn't need much knob turning to start tracking availability, and WhatsUp has a good blend of ease of use, low price and basic monitoring. It sat there happily in our system tray, monitoring our network.
Although WhatsUp isn't big on drawing complex Layer 2 maps, its straightforward display of our monitored systems made it easy for us to see device status. Instead of lots of custom views, WhatsUp streamlines device-status reporting with network, health, availability and performance views.
WhatsUp is intentionally limited to 10 monitored devices. This makes autodiscovery less important, but the process was easy to understand and launch anyway. Although many more than 10 devices can be discovered, we had to choose the lucky 10 we wanted to monitor. We did so and were up and tracking in less than five minutes.
A couple of limitations go along with this ease of use, however. For example, we had to delete a device prior to running a new autodiscovery whenever we wanted to add new devices to our group. This is an issue only on subsequent discoveries and when the number of possible devices is more than 10, but still, we wish we'd had the option to select from the original results list.
Once we'd settled on the devices to monitor, we went looking for some SNMP communities (noticeably absent as a parameter during autodiscovery) and poll frequency tweaks. Alas, WhatsUp doesn't support SNMP, and polling is predefined at five-minute intervals. Well, this does keep it simple--two fewer knobs to turn.
