Embodiments generally relate to performance testing of software code. In some embodiments, a method includes executing a software program, where the software program includes at least one target portion of code to be performance tested. The method further includes receiving a data stream, where the data stream includes a plurality of events, and where the at least one target portion of code processes the plurality of events based on an event rate. The method further includes monitoring for failures associated with the at least one target portion of code processing the plurality of events. The method further includes modifying the event rate if at least one failure is detected, where the event rate is modified until no failures are detected. The method further includes generating a performance report if no failures are detected during a target success time period.

Methods and apparatus, including computer program products, implementing and using techniques for network modeling and device configuration. A security information and event manager is configured to receive log data from third party devices connected to a network. A notification is received each time a specific third party device generates a predetermined event in response to traffic at the specific third party device. The notification includes event information inferring network topology information, which network topology information includes third party device location information, firewall event information, source and destination networks. In response to receiving this information, a state of each third party device is generated, using inferred information over a predetermined period. An access control list is generated for each third party device, by using the inferred information over the predetermined period.

Network modeling and device configuration based on observed network behavior

A mechanism is provided for reparsing unsuccessfully parsed event data. Responsive to determining that one or more unsuccessfully parsed event data items exist for a log source, each unsuccessfully parsed event data item of the one or more unsuccessfully parsed event data items is reparsing using an updated device support module associated with the log source. Responsive to the device support module successfully reparsing the unsuccessfully parsed event data item thereby forming a successfully parsed event data item, the successfully parsed event data item is added to a historical record of events associated with the log source. Responsive to the device support module failing to successfully reparse the unsuccessfully parsed event data item, the unsuccessfully parsed event data item is retained in an unsuccessfully parsed event data item data structure.
