1. A method for improving machine data analysis, comprising:
- creating a set of searchable events by segmenting raw time series machine data received from at least one data source in an information technology environment into searchable events, the raw time series machine data reflecting activity in the information technology environment, each searchable event including at least a portion of the segmented raw time series machine data thereby allowing application of time-based search phrases across at least a portion of events in the set of searchable events to search the segmented raw time series machine data in the at least a portion of the events;
detecting whether time information is present in the raw time series machine data of an event in the set of searchable events;
in response to detecting that the time information is present in the event;
extracting the time information from the raw time series machine data of the event;
determining a time zone in the extracted time information;
generating an offset by normalizing the extracted time information using the determined time zone;
generating a time stamp based on the offset; and
associating the generated time stamp with the event, thereby enabling the event to be searched using the generated time stamp;
in response to detecting that the time information is not present in the event;
calculating a time stamp for the event using one or more stored time stamps, wherein the one or more stored time stamps are time stamps stored from one or more earlier processed events selected on a periodic basis in order to facilitate time stamp creation; and
associating the calculated time stamp with the event, thereby enabling the event to be searched using the created time stamp;
wherein the method is performed by one or more computing devices.

Abstract
Methods and apparatus consistent with the invention provide the ability to organize, index, search, and present time series data based on searches. Time series data are sequences of time stamped records occurring in one or more usually continuous streams, representing some type of activity. In one embodiment, time series data is organized into discrete events with normalized time stamps and the events are indexed by time and keyword. A search is received and relevant event information is retrieved based in whole or in part on the time indexing mechanism, keyword indexing mechanism, or statistical indices calculated at the time of the search.

1. A method for improving machine data analysis, comprising:
-
creating a set of searchable events by segmenting raw time series machine data received from at least one data source in an information technology environment into searchable events, the raw time series machine data reflecting activity in the information technology environment, each searchable event including at least a portion of the segmented raw time series machine data thereby allowing application of time-based search phrases across at least a portion of events in the set of searchable events to search the segmented raw time series machine data in the at least a portion of the events; detecting whether time information is present in the raw time series machine data of an event in the set of searchable events; in response to detecting that the time information is present in the event; extracting the time information from the raw time series machine data of the event; determining a time zone in the extracted time information; generating an offset by normalizing the extracted time information using the determined time zone; generating a time stamp based on the offset; and associating the generated time stamp with the event, thereby enabling the event to be searched using the generated time stamp; in response to detecting that the time information is not present in the event; calculating a time stamp for the event using one or more stored time stamps, wherein the one or more stored time stamps are time stamps stored from one or more earlier processed events selected on a periodic basis in order to facilitate time stamp creation; and associating the calculated time stamp with the event, thereby enabling the event to be searched using the created time stamp; wherein the method is performed by one or more computing devices. - View Dependent Claims (2, 3, 4, 5, 6)

7. An apparatus for improving machine data analysis, comprising:
-
an event processor, implemented at least partially in hardware, that creates a set of searchable events by segmenting raw time series machine data received from at least one data source in an information technology environment into searchable events, the raw time series machine data reflecting activity in the information technology environment, each searchable event including at least a portion of the segmented raw time series machine data thereby allowing application of time-based search phrases across at least a portion of events in the set of searchable events to search the segmented raw time series machine data in the at least a portion of the events; wherein the event processor detects whether time information is present in the raw time series machine data of an event in the set of searchable events; in response to the event processor detecting that the time information is present in the event, the event processor; extracts the time information from the raw time series machine data of the event; determines a time zone in the extracted time information; generates an offset by normalizing the extracted time information using the determined time zone; generates a time stamp based on the offset; and associates the generated time stamp with the event, thereby enabling the event to be searched using the generated time stamp; in response to the event processor detecting that the time information is not present in the event, the event processor; calculates a time stamp for the event using one or more stored time stamps, wherein the one or more stored time stamps are time stamps stored from one or more earlier processed events selected on a periodic basis in order to facilitate time stamp creation; and associates the calculated time stamp with the event, thereby enabling the event to be searched using the created time stamp. - View Dependent Claims (8, 9, 10)
