This first variant is used for choosing the set of time series to
operate on. It selects time series that have a value for a key that is greater than or equal
to a specified value. For example, consider the following query:
name,ssCpuSystem,:ge
When matching against the sample data in the table below, the highlighted time series would be
included in the result set:
| Name | nf.app | nf.node |
| ssCpuUser |
alerttest |
i-0123 |
| ssCpuSystem |
alerttest |
i-0123 |
| ssCpuUser |
nccp |

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. For example:
| Time |
a |
b |
a >= b |

The result will be a signal time series that will
be 1.0 for intervals where the condition is true and 0.0 for intervals where it is false.
Info
Note, the data points have floating point values. It is advisable to avoid relying on
an exact equality match.
