Genti Cuni - Mountain View CA, US
Adam Schondelmayer - Cupertino CA, US

International Classification:

G06F 11/00

US Classification:

370241000, 714004000

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.

Appl. No.:

11/433236

Inventors:

Genti Cuni - Mountain View CA, US
Adam Schondelmayer - Cupertino CA, US
Timothy Beyers - San Francisco CA, US

International Classification:

H04L 12/56

US Classification:

370412000, 370252000

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.

Appl. No.:

12/346114

Inventors:

Ricardo A. Negrete - Scotts Valley CA, US
Genti Cuni - Mountain View CA, US

Assignee:

VIRTUAL INSTRUMENTS CORPORATION - Scotts Valley CA

International Classification:

G06F 11/28
G08B 21/00
G01J 1/42

US Classification:

714 37, 340540, 356218

Abstract:

A network diagnostic system may include a network diagnostic device. The network diagnostic device may be configured to receive data indicating a light level of an optical signal and to perform at least one network diagnostic function at least partially in response to the receipt of the data. A network diagnostic method may include detecting a light level of an optical signal; and performing at least one network diagnostic function at least partially in response to the detection of the light level of the optical signal. Exemplary network diagnostic functions may include triggering an alarm; triggering a capture of at least a portion of one or more network messages; storing data indicating the light level of the optical signal on a computer readable medium (e.g., for use in subsequent reports); and/or any other suitable network diagnostic function.

International Classification:

G06F 15/16

US Classification:

709224

Abstract:

A system may comprise a network diagnostic device. The network diagnostic device may be configured to instantiate objects of data collection classes. The data collection classes may be configured to collect data from nodes of a network. The data collection classes may, for instance, inherit an interface object from an ancestor data collection class, and the interface object may be configured to use a protocol to collect data from nodes of a network. The network diagnostic device may be configured to automatically detect a node type associated with a node of a network. The network diagnostic device may also be configured to instantiate a node-specific data collection object associated with the detected node type. The node-specific data collection object may be configured to collect data from nodes of the detected node type at intervals less than or equal to fifteen seconds.

Inventors:

- San Jose CA, US

Genti Cuni - Mountain View CA, US

Assignee:

Virtual Instruments Corporation - San Jose CA

International Classification:

H04L 12/26
H04L 29/08

Abstract:

A link in a storage area network (SAN) is identified that is being affected by one or more slow draining devices. Devices in the SAN are identified as candidates for potentially being a slow draining device affecting the link. For each identified candidate device, metric data is identified that describes, for example, traffic activity of the candidate device, such as data transmission rates of the candidate device. Additionally, metric data is identified for the link. For each candidate device, a correlation value is determined that indicates the likelihood that the candidate device is a slow draining device affecting the link. The correlation value of a candidate device is determined based on the correlation between the metric data of the device and the metric data of the link. One or more of the correlation values are presented to a user via a user interface.
