Abstract: Methods and systems are described for storing network device identities and application assignments as a function of time to facilitate analysis of network devices and applications even in a temporally dynamic network. Server assignments are stored as a function of time for various applications executed within a network. Performance data are indexed according to a server and/or port unique identifier and stored as a function of time. Using the time-based server assignments and time-based performance data, the system can be queried using at least one of an application and intermediate entity identifier to determine the performance of the application, the entity, or both at one or more points in time.

Abstract: A diagnostic device, such as a network probe or a blade, with wired and/or wireless communication capabilities. In one example embodiment, a network probe includes a processor, a memory in communication with the processor, and a buffer in communication with the processor. In this example embodiment, the processor is programmed to identify a triggering event in data received by the network probe and store, in the buffer, data that is associated with the triggering event.

Abstract: A network diagnostic module may use network configuration data in performing network diagnostic methods. The network diagnostic module may use network configuration data to generate baseline network activity data. The network diagnostic module may use network configuration data to identify network components and aggregate network activity data for the components. The network diagnostic module may use network configuration data to identify sets of network components and to access network activity data for the sets. The network diagnostic module may use network activity data to identify sets of network components and to access network configuration data for the sets.

Abstract: A network diagnostic system may include one or more network diagnostic components. The network diagnostic components may be configured to capture at least a portion of one or more network messages. The network diagnostic components may include a plurality of buffers, and the network diagnostic components may be configured to capture at least a portion of one or more network messages in the buffers. The network diagnostic components may be configured to execute the captures in response to capture trigger. A trigger module may be configured to provide the capture trigger in response to detecting one or more conditions. The trigger module may be configured to provide the capture trigger in response to detecting a statistic that is outside a particular range of values. The trigger module may be configured to provide the capture trigger in response to detecting a change in network configuration data associated with a networking system.

Abstract: This disclosure relates to a wireless diagnostic device, such as a network probe or a blade, with wireless communication capabilities. In one example embodiment, a network probe includes a processor, a memory in communication with the processor, a buffer in communication with the processor, and a first wireless transceiver in communication with the processor. In this example embodiment, the first wireless transceiver is configured to transmit data over a wireless channel.

Abstract: A data analyzing system. The data analyzing system includes a number of data capture devices. The data capture devices may be for example, at different points in a network or for testing different components in a system. The data analyzing system further includes a distributed storage system connected to the data capture devices. The distributed storage system includes one or more portal servers. The distributed storage system further includes a number of storage servers coupled to the one or more portal servers. The one or more portal servers are configured to direct data from the data capture devices to the storage servers.

Abstract: A networking system is provided. The networking system may include a diagnostic module. The diagnostic module may perform any of a variety of network diagnostic functions. The diagnostic module may include an analysis module, which may receive messages and perform any of a variety of network diagnostic functions using the messages it receives. The diagnostic module may include a logic module, which may receive network messages having a first format or structure, may process the network messages it receives into network messages having a second format or structure, and may send the processed messages to the analysis module. The logic module may receive the network messages from an aggregated link.
