Output Stack:| (ts1 + ts2): TimeSeriesExpr | | |
|
Compute a new time series where each interval has the value (a addNaN b) where a
and b are the corresponding intervals in the input time series.
NaN values are handled specially: if either input is NaN, it is treated as 0 for the operation.
If both inputs are NaN, the result is NaN. This differs from strict floating point addition
where any NaN input produces NaN output.

Examples
Adding a constant value to a time series:
| Before | After |
 |  |
name,sps,:eq,
30e3
| name,sps,:eq,
30e3,:add
|
Adding two time series together:
| Before | After |
 |  |
name,requestLatency,:eq,
:sum,
name,requestsPerSecond,:eq,
:max,
(,name,),:by
| name,requestLatency,:eq,
