Cisco UCS Manager Plugin Release 0.9(4) for Nagios

Version 13

    We are pleased to release Cisco UCS Manager Plugin 0.9.4 for Nagios

     

    Nagios is an open source computer system monitoring, network monitoring and infrastructure monitoring software application. Nagios offers monitoring and alerting services for servers, switches, applications, and services.


    The solution provides end-user with two components.

    • The first is the Nagios monitoring plugin script (cisco_ucs_nagios) which will provide end-user with the capability of monitoring the components like blade servers, rack servers, fabric interconnects, chassis, IO Modules, fabric extenders in one or more UCS domains.
    • The second is an add-on to the Nagios, which will provide end-user with the capability to auto discover UCS domain and create the host definitions in Nagios . It also creates the service definitions for the services defined in the configuration file. By default, the addon is shipped with basic service definitions for each UCS component (aka host in Nagios) which use the cisco_ucs_nagios script to monitor their health. Refer to the user guide section 5.1 for the list of services defined by the addon. For components/hosts which are not healthy, it gives the associated faults and their details. For components/hosts which are healthy, it gives the inventory details.
