Review: The best network monitoring system on earth
ScienceLogic EM7 brings ultraflexible, ultrascalable, carrier-grade network monitoring to the enterprise
Built for big networks
One point I want to make very clear is that EM7 should not be compared to WhatsUp Gold or other network monitoring systems designed for the single enterprise. This is a carrier-class system that was born from engineers working with national and international carriers that needed enough flexibility to handle hundreds of entities and a similar number of connected networks. The fact that EM7 can use national weather service map overlays to put potential trouble spots into perspective gives you a good idea of the system scope the Science Logic folks are used to. Even so, keep in mind that I've been using EM7 for the past year or so in a single college on a single campus at a single university. Pricing is a function of the number of systems you're monitoring.
In other words, the EM7 pricing structure doesn't differentiate between a flat enterprise network with 1,000 devices to monitor as opposed to our network that includes dozens of labs with projects behind their own firewalls. All of this sits on a collection of NAT Class C IPv4 subnets -- some with public addressing and a smaller number making the transition to IPv6. If you have projects behind NAT firewalls, you can put in a virtual machine collector that feeds systems information to the main EM7 database for the same price as a flat network with a single collector. If you're not virtualized yet, the database and collectors are also available as a physical appliance. We make use of both physical and virtual appliances.
