This chapter explains how health is calculated and how you can drill down to the root cause of a problem.

NetIM lets you view your entire monitored infrastructure and quickly assess its health before you even click a button. The health of a device and its interfaces is determined by comparing a selected set of metrics against default thresholds, where the thresholds have the same values as those used in the Default Alert Profile. The health of a site's devices is aggregated to the site level. Similarly, the health of a device's interfaces is aggregated both to the device level and then up to the site and group level.
