Method Detail

time

public long time(Stat name)

Note: time stats are measured in nanoseconds and after conversion to millisecond it may become 0. Usually it makes no sense to log such small values, and 0 value makes it easier to filter out them. In contrast, when using humanTime(Stat) for such timers, correct value will be printed.

Parameters:

name - statistic name

Returns:

collected time in milliseconds or 0 (is stat value is not available)

Throws:

java.lang.IllegalStateException - if provided stat is not time stat

humanTime

public java.lang.String humanTime(Stat name)

Value is reported in best suited units (e.g. milliseconds, seconds, minutes etc).

Parameters:

name - statistic name

Returns:

human readable (formatted) timer value or 0 (if stat value is not available)

Throws:

java.lang.IllegalStateException - if provided stat is not time stat

count

public int count(Stat name)
