Kloudfuse has a large number of functions for examining the logs.
Algorithms
Overlay a band on the metric, showing the expected behavior of a series based on past values.
Highlight outliers series.
Forecast future values based on past values.
Arithmetic
Absolute value
Absolute value of the metric.
Ceil
Rounds up the sample values of all elements in the time series to the nearest integer.
Cube root
Calculates the cube root of a numeric element; \$root(3)(value)\$.
Exponential
Calculates the exponential function for all elements of the time series.
Expm1
Calculates the \$e(x)-1\$ function for all elements of the time series; compensates for the roundoff error in Exponential.
Floor
Rounds down the sample values of all elements in the time series to the nearest integer.
Log
Calculates the natural logarithm of all values in a time series; loge.
Round
Rounds the sample values of all elements in the time series to the nearest integer.
Square root
Calculates the square root of all values in the time series, \$sqrt(value)\$.
