There's no debate about the need for centralized network monitoring. The potential benefits are numerous, including improvedend-use productivity,network performance,application performance andsecurity and compliance.There are three main approaches to network monitoring: Simple Network Management Protocol (SNMP), flow records and packet-based. There are pros and cons to each when considering issues like data granularity (as high level as just the source and destination, or as low as every bit in every packet), data accuracy (sampled methods can miss critical data and thus be less accurate, whereas methods which interrogate every packet are 100 percent accurate), overhead (how much additional traffic is added to the network and competition for processing power and memory on the network devices themselves) and cost.SNMP is best used in identifying and describing system configurations. It monitors network-attached devices for basic high-level conditions like up/down, total traffic (bytes, … [Read more...] about EXPERT ADVICE What’s on the Wire?
