A method and apparatus of a device that dynamically changes how management data is managed in response to events detected in a network system is described. In an exemplary embodiment, the device detects an event occurring in the network system. The device further determines if the event triggers a system change in how the management data is reported on one or more of the managed nodes. If the event notification does trigger the system change, for each of the one or more of the managed nodes, the device determines a command for that manage node that represents a specific change in how frequent the management data is reported to the network management system. In addition, the device sends the command to that managed node, where the agent applies the command to the managed node and the applied command implements the specific change in how frequent the management data is reported to the network management system.

As disclosed herein, a method, executed by a computer, for analyzing a performance metric includes distributing link connection information for a network to each node in the network, pairing each node with another node in the network to provide paired nodes, testing a performance metric for the paired nodes, and generating a performance report for the network. The method may further include receiving link connection information for the network. The method may further include constructing a connectivity graph based on the received link connection information. The method can be used to test link performance within non-homogeneous networks.

The disclosure is related to a framework that enables server-side controlling of data sampling at client devices. An application executing on a client device samples data related to various aspects of the application, generates a log file containing the sample data and transmits the log file to the server. The application samples the data based on specified criteria, e.g., specified events, specified actions of a user of the client device, at a specified sampling rate. The framework enables controlling the sampling of such data from the server. The framework can be used to configure various parameters of the sampling, including a number of users to be sampled, a set of events to be sampled, a sampling rate for the events, etc. After the configuration is determined, the server transmits a configuration file to the client device, which performs the sampling based on the configuration in the configuration file.

A heartbeat packet timer identification method and a device, where the identification method is performed by a device that sets a timer, and the method includes determining, in a data packet transmitted by the device, each associated data packet corresponding to each timing end moment of the timer and determining, according to each associated data packet and each timing end moment of the timer, whether the timer is a heartbeat packet timer set by the device for transmitting a heartbeat packet. With reference to a data packet transmitted by a device and each associated data packet that corresponds to each timing end moment of a timer, the heartbeat packet timer identification method and the device may determine with relatively high accuracy whether the timer is a heartbeat packet timer.

Example methods are provided for a network device to perform adaptive polling in a software-defined networking (SDN) environment. One example method may comprise: operating in a polling mode at a current polling round to detect zero or more packets that require packet processing by the network device. The method may also comprise: determining packet characteristic information associated with multiple polling rounds that include the current polling round and one or more previous polling rounds; and based on the packet characteristic information, determining whether a resource performance condition associated with the network device is satisfied. In response to determination that the resource performance condition is satisfied, the network device may operate in the polling mode at a subsequent polling round; but otherwise, switch from the polling mode to an interrupt mode.

A method for managing message transmission times from a first device to a destination of a second device. The devices have respective electrical load levels at a given time. The method includes receiving a request to change message transmission times, the request including the current electrical load level associated with the second device; and determining transmission times by taking into account the load levels of the first and/or second device.

A first network device is configured to: transmit data packets and poll messages to a second network device; and receive, in response to each poll message, at least one status message from the second network device. The at least one status message indicates which of the data packets sent before that poll message have been correctly received at the second network device and/or have been lost. The first network device is configured to adapt a rate of transmitting the poll messages based on a set of parameters. Further, a second network device is configured to: receive data packets from a first network device; and transmit at least one unsolicited status message to the first network device, in case of certain conditions.

Aspects of the technology provide solutions for determining a time period (“epoch”) required to monitor or analyze a tenant network. Some implementations of the technology include a process for making automatic epoch determinations, which includes steps for identifying one or more network parameters for a tenant network, analyzing the tenant network using the network parameters to discover one or more configuration settings of the tenant network, and determining a first epoch for the tenant network, the first epoch corresponding with a period of time to complete analysis of the tenant network using the network parameters. In some aspects, the process can further include steps for generating a tenant profile for the tenant network, the tenant profile based on the network parameters, the first epoch, and the one or more configuration settings of the tenant network. Systems and machine-readable media are also provided.

A method comprising: receiving network traffic data from a network traffic monitoring platform, the network traffic data identifying communication between entities of an enterprise network and storage monitoring data from a server-based SAN monitoring platform, the storage monitoring data identifying communication between a software-only server-based SAN and entities of the enterprise network, parsing the received traffic data and storage monitoring data to identify object data and/or metric data, creating a metric table entry from metric data, creating an object table entry from object data linking metric table entries with object table entries, creating a link table entry from the linking of metric table entries with object table entries, for each link table entry, assigning an object performance threshold, comparing each metric table entries to the assigned object performance threshold, if an alarm trigger condition is satisfied based on the comparison, then triggering an alarm event and outputting an alarm notification.

Systems and methods are provided for automatically responding to network connectivity issues in a media stream. One example method includes transmitting, from a first computing device, a media stream to one or more secondary computing devices. A network connectivity issue between the first computing device and one or more of the secondary computing devices is detected. If a network connectivity issue is detected, a notification is transmitted to one or more of the secondary computing devices.
