1. A system for indexing and aggregating proxy server data, the system comprising: a memory device configured to store a set of instructions; and one or more processors configured to execute the set of instructions to: receive a plurality of log lines of proxy server data comprising a plurality of data components; index one or more of the plurality of data components for the plurality of log lines; generate a set of structured log data records, each including the one or more indexed data components; generate a set of first summarized data records, each first summarized data record of the set generated by aggregating one or more log data records of the set of log data records having at least one matching indexed data component, wherein each first summarized data record includes fewer indexed data components than a log data record; and generate, after passage of a predetermined period of time since generation of the set of first summarized data records, a set of second summarized data records, each second summarized data record of the second set generated by aggregating one or more first summarized data records having a matching subset of the indexed data components, wherein each second summarized data record includes fewer indexed data components than a first summarized data record.
