This update to NMIS is a really big one, almost 12 months in the making. There have been a lot of improvements to how NMIS will run and handle all sorts of data that is thrown at it.

Some highlights in this release:

  • Extensive modelling improvements that include updates for Arista and Arris devices,  new models for Dell switches, updated and extended modelling of the Host Resources MIB.
    adjustments for Cisco Catalyst IOSXE devices, Nexus CBQoS modelling, substantially improved modelling for Net-SNMP devices.
  • The installer now handles Debian 10 (Buster), and NMIS works correctly on Debian 8 to 10.
  • The node selection, scheduling of operations and process management have been reworked extensively, and NMIS spreads the load now better and more evenly.
    • the new config options nmis_max_nodes_per_collect_cycle, nmis_max_nodes_per_services_cycle and nmis_max_nodes_per_update_cycle  were added to optionally limit how many nodes should be considered at most for an operation cycle.
