LogParser get results from last hour


I have cpu monitors constantly workning on my computer. I would like log parser to parse results only from the last hour. does anyone know how to do that?

SELECT TO_STRING(QUANTIZE(TO_TIMESTAMP(Field1, 'mm/dd/yyyy HH:mm:ss.ll'),10 ), 'hh:mm:ss') AS Time, AVG(TO_REAL(Field2)) AS Cpu
INTO .\output\cpu.csv
FROM .\logs\*.csv   
WHERE Time >= SUB( TO_LOCALTIME(SYSTEM_TIMESTAMP()), TIMESTAMP('0000-01-02', 'yyyy-MM-dd') )

the last line results with an error. does anyone know how can i do that? thanks!


Solution

  • Your WHERE clause is wrong; instead of pulling 1 hour, you're pulling 1 day.

    The following worked on IIS logs:

    SELECT TO_STRING(QUANTIZE(TO_TIMESTAMP(date, time),10 ), 'hh:mm:ss') AS Time
    INTO asdf.csv
    FROM W3SVC5\*ex*.log
    WHERE TO_LOCALTIME(TO_TIMESTAMP(date, time)) >= SUB( TO_LOCALTIME(SYSTEM_TIMESTAMP()), TIMESTAMP('0000-01-01 01:00', 'yyyy-MM-dd HH:mm') )
    

    For your particular case you should be safe just using this bit of the WHERE clause:

    SUB( TO_LOCALTIME(SYSTEM_TIMESTAMP()), TIMESTAMP('0000-01-01 01:00', 'yyyy-MM-dd HH:mm') )
