- An annotation is an event that is overlaid on top of graphs. The query can have up to four columns per row, the <b>time</b> column is mandatory. Annotation rendering is expensive so it is important to limit the number of rows returned.
- - column with alias: <b>time</b> for the annotation event time. Use epoch time or any native date data type.
- - column with alias: <b>timeend</b> for the annotation event end time. Use epoch time or any native date data type.
- - column with alias: <b>text</b> for the annotation text.
- - column with alias: <b>tags</b> for annotation tags. This is a comma separated string of tags e.g. 'tag1,tag2'.
- Macros:
- - $__time(column) -> column AS time
- - $__timeEpoch(column) -> DATEDIFF(second, '1970-01-01', column) AS time
- - $__timeFilter(column) -> column BETWEEN '2017-04-21T05:01:17Z' AND '2017-04-21T05:01:17Z'
- - $__unixEpochFilter(column) -> column >= 1492750877 AND column <= 1492750877
- - $__unixEpochNanoFilter(column) -> column >= 1494410783152415214 AND column <= 1494497183142514872
- Or build your own conditionals using these macros which just return the values:
- - $__timeFrom() -> '2017-04-21T05:01:17Z'
- - $__timeTo() -> '2017-04-21T05:01:17Z'
- - $__unixEpochFrom() -> 1492750877
- - $__unixEpochTo() -> 1492750877
- - $__unixEpochNanoFrom() -> 1494410783152415214
- - $__unixEpochNanoTo() -> 1494497183142514872
