Removes the macro function . Macro functions should not do UTC/timezone conversion - they should work in the same way as postgres and mysql datasource implementations. Grafana and Microsft SQL Server should be run on servers with UTC timezones.

|
|
An annotation is an event that is overlayed on top of graphs. The query can have up to three 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). Use unix timestamp in seconds 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 >= DATEADD(s, 18446744066914186738, '1970-01-01') AND column &t;= DATEADD(s, 18446744066914187038, '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, '1970-01-01')
|
|
- $__timeTo() -> DATEADD(second, 1492750877, '1970-01-01')
|
|
- $__unixEpochFrom() -> 1492750877
|
|
- $__unixEpochTo() -> 1492750877
