Dynamic thresholds: When it comes to selecting the right thresholds to trigger alerts, one size does not fit all networks. Recognizing that, better performance-management products seek to set thresholds that represent the norm for each particular network. This is key because static thresholds mean a flood of false warnings, and like the cries of the boy who cried wolf, critical notifications then cease to be effective operational diagnostic triggers.
Two companies creating such dynamic thresholds are ProactiveNet and Panacya. Both vendors' products watch existing traffic and set high and low values based on differences seen over a range of times. For example, traffic on a particular interface or for a specific service might seem unusually high, but is it high every month on the day after accounting closes the books? This is the kind of sensitivity that will let you see the threshold in context of what's normal for your network.
Granular reports: SeaNet Technologies is cutting through data glut with granular data and smart rollup features. Using probes and gathering all data flows, its SeaView adds to the usual min/max/avg rollups data for every TCP transaction and variances for each, which are lost when data is averaged.
