Systems and methods for generating a user file activity audit report

A computer-implemented method for generating a user file activity audit report comprising:

• sending from a file storage device to a proxy server comprising a processor and memory programmed to execute a proxy monitor, wherein the proxy monitor receives from the file storage device a plurality of real-time user file notifications related to file events generated by a user on a first file;
• determining from the plurality of real-time user file notifications a file event set for the first file, wherein the file event set comprises:
• an open source file event, a read source file event, an open destination temporary file event, a write to destination temporary file event, a destination temporary file close event, and a temporary file rename event;
• pruning events from the file event set to generate an optimized file event set comprising read source file event, a write to destination temporary file event, and a destination temporary file close event;
• sending the optimized file event set to a proxy monitor database wherein the proxy monitor database comprises optimized file event information record comprising a record ID and optimized file event set, and sending the optimized file event information record from the proxy monitor database to an index server comprising an audit core index and metadata index,
• wherein the audit core index comprises an index of the optimized file event information record received in real-time of the first file and the metadata index comprises an index of the metadata for the first file generated during a storage operation of the first file;
• receiving by the proxy monitor a response wherein the response is one of:
• a transmission success notification for the optimized file event information record and a transmission failure notification for the optimized file event set information record, and
• pruning the optimized file event information record from the proxy monitor database in response to the transmission success notification of the optimized file event set information record, and
• rereading the optimized file event information record from the proxy monitor database and resending the optimized file event information record to the index server in response to the transmission failure notification of the optimized file event information record to the index server;
• and
• generating a user audit report by the index server comprising the optimized file event information record for the first file from the audit core index and the metadata index information for the first file from the metadata index and presenting the user audit report on a user interface.
