Summary
sample(<numberOfTimeSeries>, <tsExpression>)
Returns numberOfTimeSeries
non-random time series based on the expression. This function is deterministic as long as the underlying set of time series stays the same. However, the returned values can change, for example, if a new source starts reporting the metric.
Parameters
Parameter | Description |
---|---|
numberOfTimeSeries | Number of time series that you want. You can express this parameter as a number (e.g. 10) or a percentage (e.g. 17%). |
tsExpression | Expression that you want to filter. |
Description
Returns numberOfTimeSeries
non-random time series based on the expression. This function is deterministic as long as the underlying set of time series stays the same. The returned values might change, for example, if a new source starts reporting the metric.
Examples
The following example shows first the result of a query that returns a fairly large number of time series.
We can use sample()
to return 10% the time series, in this example, 3.

For a random set of time series, use the random() function.
