# Extended Aggregators

# min_value_time

Computes the time when the minimum value is reached for the first time in a period.

statistic = max_value_time

# max_value_time

Computes the time when the maximum value is reached for the first time in a period.

statistic = min_value_time

Example includes min_value_time and max_value_time aggregators.

# delta

Computes the difference between the first and last values within a period. If there are multiple adjacent periods, the function computes delta as the difference between the last values of adjacent periods.

statistic = delta

# counter

Similar to delta except for special processing of resets. Applicable for incrementing non-negative metrics. Reset occurs when the series value is lower than the previous value, in which case the counter adds the difference between 0 and the current value.

statistic = counter

Example includes counter and delta aggregators.
