The Grouped Availability Report computes reachability statistics similar to the Node Availability Report, but devices are then categorised based on their overall availability metric; the report shows these results spread over various summary table sections (for HTML output) or work sheets (for XLSX output). Both business days and business hour filtering are supported. The availability categories can be configured flexibly by adjusting thresholds and settings.
A combined total availability metric for all nodes is computed and presented in a summary section, and similar metrics and categorisation device counts for both grouping by Customer and Group (ie. NMIS configuration properties customer and group) are computed and presented. Finally the detailed availability stats are shown for all devices, in order of the devices' group memberships. Instead of determining the an individual device devices availability as the Node Availability Report does, the Grouped Availability Report will calculate and give is based on the overall availability metric and gives a summary of the overall availability of all the devices within a specific group as well as display . The summary section displays the number of devices within that group, the number customers within the group, the number of groups and the overall availability of them . The Grouped Availability Report also displays the Down%, Packet Loss %, No Data %, Uptime, and Downtime for a quick look at overall network health.
