Method and apparatus for parsing log data

A computing device, comprising:

• one or more processors;
• a memory configured to load a computer program executed by the one or more processors;
• and
• a storage configured to store the computer program,
• wherein the computer program comprises instructions for performing operations of:
• loading a plurality of unit logs identified by first-parsing log data in a two-dimensional matrix into the memory, wherein the log data comprises a plurality of raw unit logs, and each of the plurality of unit logs constitutes one row and comprises items that are parsed from a plurality of items of each of the plurality of raw unit logs;
• determining a target item to be second-parsed among the items loaded into the memory;
• dividing data of the target item into a plurality of sub-items by second-parsing the data of the target item, among the items loaded in the two-dimensional matrix into the memory;
• and
• storing a second-parsing result including the plurality of sub-items,
• wherein the loading of the plurality of unit logs in the two-dimensional matrix into the memory comprises:
• identifying a log format that corresponds to a type of the log data, among pre-stored log formats that are different for each type of log data, wherein the log format provides an order and a definition of each item in a raw unit log of the log data;
• determining at least one item that are indexed in the identified log format, the at least one item being a subset of a plurality of items included the raw unit log;
• and
• first-parsing a unit log, including the indexed at least one item, and loading the unit log into the memory.
