Abstract: In one embodiment, a method includes monitoring a network that includes a plurality of information handling systems. The plurality of information handling systems includes a plurality of computer-networking devices and a plurality of remote nodes. The method further includes creating a stored network topology. The stored network topology includes, for each of the plurality of networking devices, any direct children. The creating includes, for each networking device of the plurality of computer-networking devices, selecting the networking device, querying the networking device for topology information, and receiving the topology information from the networking device. The creating also includes adding any directly connected remote nodes to the stored network topology. In addition, the creating includes determining any new parent references that can be inferred based on the topology information. The creating further includes updating the stored network topology according to the new parent references.

Abstract: In one embodiment, a method includes, on a monitoring system, maintaining hot-cluster data. The hot-cluster data includes identification of at least one hot cluster. The at least one hot cluster includes at least one hot-cluster remote node and is served by two or more hot-cluster networking devices. The method further includes selecting a monitoring request and transmitting the monitoring request to the two or more hot-cluster networking devices as a passive request. Via the passive request, the two or more hot-cluster networking devices are instructed to: not forward the monitoring request to the at least one hot-cluster remote node until a control request is received from a communicably separate control system; and upon receipt of the control request, transmit the monitoring request and the control request to the at least one hot-cluster remote node together as a piggy-back request.

Abstract: A management system sends a first request for first data associated with multiple network entities. If the first request times out, the first request is split to create multiple smaller requests and the multiple smaller requests sent, requesting data from a subset of the multiple network entities. Based on responses to the multiple smaller requests, the management system identifies a particular network entity that caused the first request to time out and adds the particular network entity to a set of problematic entities. The management system sends a second request that requests second data from a portion of the multiple network entities that excludes the particular network entity. The multiple network entities may include one or more of a virtual machine (VM), a host node (to host VMs), a storage device, a network link, another type of network entity, or any combination thereof.

Abstract: In one embodiment, a method includes registering as a listener for availability notifications from at least one low-availability device. The method further includes determining a data-collection schedule of the at least one low-availability device. In addition, the method includes maintaining a prioritized queue comprising required data items needed from the at least one low-availability device. Also, the method includes preparing, in advance of the at least one low-availability device becoming available, a request for at least one required data item. The at least one required data item includes a highest-priority data item in the prioritized queue. The method additionally includes, responsive to a notification that the at least one low-availability device is available, transmitting the request to the at least one low-availability device.
