every

Function

every bucket ts using a duration

Synopsis

every(d: duration) -> time

Description

The every function is a shortcut for bucket(ts, d). This provides a convenient binning function for aggregations when analyzing time-series data like logs that have a ts field.

Examples

Operate on a sequence of times:

echo '{ts:2021-02-01T12:00:01Z}' | zq -z 'yield {ts,val:0},{ts:ts+1s},{ts:ts+2h2s} | yield every(1h) | sort' -

->

2021-02-01T12:00:00Z
2021-02-01T12:00:00Z
2021-02-01T14:00:00Z

Use as a group-by key:

echo '{ts:2021-02-01T12:00:01Z}' | zq -z 'yield {ts,val:1},{ts:ts+1s,val:2},{ts:ts+2h2s,val:5} | sum(val) by every(1h) | sort' -

->

{ts:2021-02-01T12:00:00Z,sum:3}
{ts:2021-02-01T14:00:00Z,sum:5}
