Embodiments describe techniques for reducing resource overhead in verbose trace operations by recursively pruning object data prior to string serialization. According to one embodiment, a trace operation is initiated. The trace operation generates a string and specifies one or more objects to serialize and append to the string. At least one object is a nested object. The trace operation recursively parses the nested object while generating the string. Data associated with one or more of the objects to prune from the serialization is determined based on a current prioritization level. The one or more objects is serialized into the string.

Systems and methods for efficiently obtaining a summary from and locating data in a log file allow a user to efficiently obtain summary information and locate specific data records even in large log files. The system includes a configuration program, a log writing program, and a log reading program. The configuration program allows the user to control the duration of monitoring and the frequency of summary record creation by the log writing program. The log writing program writes data records, summary records, and summary information to a log file in response to monitored events. The log reading program retrieves summary records and data records from the log file using summary information in response to user requests.
