  • Volt Statistics populating AVG_EXECUTION_TIME and MAX_EXECUTION_TIME with '\N'

    In the statistics reported by VOLT for PROCEDURE, I see '\N' populated in the AVG_EXECUTION_TIME and MAX_EXECUTION_TIME fields instead of an INTEGER.

    According to Volt documentation this field is supposed to be an INTEGER:

    Code:
    "TIMESTAMP","HOST_ID","HOSTNAME","SITE_ID","PARTITION_ID","PROCEDURE","INVOCATIONS","TIMED_INVOCATIONS","MIN_EXECUTION_TIME","MAX_EXECUTION_TIME","AVG_EXECUTION_TIME","MIN_RESULT_SIZE","MAX_RESULT_SIZE","AVG_RESULT_SIZE","MIN_PARAMETER_SET_SIZE","MAX_PARAMETER_SET_SIZE","AVG_PARAMETER_SET_SIZE","ABORTS","FAILURES"
    "1465050135851","2","ypgprd2ocsdb4","1","2","GYSESSIONDEFINITION_GetExpiredTimers","10","0","9223372036854775807","\N","0","2147483647","\N","0","51","51","0","0","0"
    It looks like it has overflowed the integer range or something? Has anyone seen this before?

    Most of the timings and counts in PROCEDURE are sampled, except for INVOCATIONS, which is the actual count. To see how many samples were taken, look at TIMED_INVOCATIONS. In your case, the count is 0, which is why you're getting weird values like "\n" and LONG_MAX, and LONG_INT for some other values. You should throw away any values when TIMED_INVOCATIONS is 0.
