Output Stack:(ts1 / ts2): TimeSeriesExpr | |
|
Compute a new time series where each interval has the value (a / b)
where a
and b
are the corresponding intervals in the input time series.
Special handling for division by zero:
- If both
a
and b
are 0, the result is 0 (instead of NaN)
- If only
b
(divisor) is 0, the result is NaN

Examples
Dividing a time series by a constant:
Before | After |
 |  |
name,sps,:eq,
42
| name,sps,:eq,
42,:div
|
Dividing two time series (e.g., calculating error rate):
Before | After |
 |  |
name,sps,:eq,
:sum,
name,requestsPerSecond,:eq,
:max,
(,name,),:by
| name,sps,:eq,
:sum,
name,requestsPerSecond,:eq,
:max,
(,name,),:by,
:div
|
- :add - Add two time series
- :sub - Subtract two time series
- :mul - Multiply two time series
- :fdiv - Strict floating point division (NaN / anything = NaN)
- :avg - Calculate average (uses division internally)
