An annotation is an event that is overlayed 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 (in UTC), as a unix time stamp or any sql native date datatype.
2017-12-02 05:40:12 -06:00
- 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:
2017-12-12 14:43:24 -06:00
- $__time(column) -> column AS time
- $__utcTime(column) -> DATEADD(second, DATEDIFF(second,GETDATE(),GETUTCDATE()), column) AS time
- $__timeEpoch(column) -> DATEDIFF(second, {d '1970-01-01'}, DATEADD(second, DATEDIFF(second,GETDATE(),GETUTCDATE()), column) ) AS time
2017-12-02 05:40:12 -06:00
- $__timeFilter(column) -> column > DATEADD(s, 1492750877+DATEDIFF(second,GETUTCDATE(),GETDATE()), '1970-01-01') AND column < DATEADD(s, 1492750877+DATEDIFF(second,GETUTCDATE(),GETDATE()), '1970-01-01')
- $__unixEpochFilter(column) -> column > 1492750877 AND column < 1492750877
Or build your own conditionals using these macros which just return the values:
- $__timeFrom() -> DATEADD(second, 1492750877+DATEDIFF(second,GETUTCDATE(),GETDATE()), '1970-01-01')
- $__timeTo() -> DATEADD(second, 1492750877+DATEDIFF(second,GETUTCDATE(),GETDATE()), '1970-01-01')
- $__unixEpochFrom() -> 1492750877
- $__unixEpochTo() -> 1492750877
