Usage Details

fetchCorrelatedEvents(inputTable, correlationTables, timeSpread, filterExpressions, aggregators)

Input

inputTable: Table containing the data for to run the operator.
correlationTables: Name of the additional tables to correlate.
timeSpread: Range (+/-) of events from correlation tables to correlate to each event in the table name.
filterExpressions: Additional join columns. For example, to correlate events from the first correlation table if the time range matches and its correlated_table.server_name matches the main_table.server column, add correlated_table.server_name = main_table.server as the first entry. There must be one expression for each correlation table.
aggregators: Additional columns to create based on all correlated events for a given event in the main table.

Output

Given a timestamp and +/- interval in minutes, pull the corresponding events from given event types and put all that data into a new table.

Example

fetchCorrelatedEvents(
  dt_lsof, 
  [ dt_pan_thread ], 
  "5 s", 
  [ "dt_lsof.date_mday = dt_pan_thread.date_mday" ], 
  [ "max(dt_pan_thread.signature_id) as m"])
