US Patent:

20120246287, Sep 27, 2012

Filed:

Feb 3, 2012

Appl. No.:

13/365484

Inventors:

Patrick MALLOY - Washington DC, US
Peter Anthony CROSBY - Edmond OK, US

Assignee:

OPNET TECHNOLOGIES, INC. - Bethesda MD

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

The present invention relates to correlating requests between a client and a server to a particular transaction. In one embodiment, transactions in a system of clients and servers are monitored and traced. From this information, a context comprising sets or groupings of transaction call sequences are determined. For example, a sequence of method calls on a client process is traced to a socket carrying data for transmission of a request message to a server. In response to this request message, the server then executes a set of method calls that can be correlated to the request message and the socket. This set of actions is considered part of a causally related grouping, and thus, associated together. In one embodiment, HTTP requests from a client may be comprise a unique custom header that is readily identified and traced. For other protocols, a client socket is associated with a corresponding server socket or to data received over a socket receive call.

International Classification:

H04L 12/26

US Classification:

709224

Abstract:

The present invention relates to managing data generated by software transactions, such as event tracing software. In one embodiment, data generated by event tracing software is monitored. The throughput of the data generated may then be modulated based on various criteria, such as a target data rate. The throughput target may be specified on a per-system basis or individual basis. Based on the throughput, the level of detail recorded is modulated. Individual processes may determine a limit or quota depending on their contribution to the throughput. In one embodiment, the method calls for a trace are modified with different property specifications to meet a desired throughput of event tracing data.
