Use the ConvertSqlTimeColumnToEpochMs function to convert any native datetime data type or epoch time (millisecond precision). Refactored mysql implementation to make it more similar to postgres and mssql implementations. Added $__timeEpoch macro function with same implementation as $__time. Added possibility to use a time column named time in addition to the currectly supported time_sec. Additional tests and update of existing. Added test dashboard.

|
|
An annotation is an event that is overlayed on top of graphs. The query can have up to three columns per row, the <i>time</i> or <i>time_sec</i> column is mandatory. Annotation rendering is expensive so it is important to limit the number of rows returned.
|
|
|
|
- column with alias: <b>time</b> or <i>time_sec</i> for the annotation event 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) -> UNIX_TIMESTAMP(column) as time (or as time_sec)
|
|
- $__timeEpoch(column) -> UNIX_TIMESTAMP(column) as time (or as time_sec)
|
|
- $__timeFilter(column) -> UNIX_TIMESTAMP(time_date_time) > 1492750877 AND UNIX_TIMESTAMP(time_date_time) < 1492750877
|
|
- $__unixEpochFilter(column) -> time_unix_epoch > 1492750877 AND time_unix_epoch < 1492750877
|
|
|
|
Or build your own conditionals using these macros which just return the values:
|
|
- $__timeFrom() -> FROM_UNIXTIME(1492750877)
|
|
- $__timeTo() -> FROM_UNIXTIME(1492750877)
|
|
- $__unixEpochFrom() -> 1492750877
|
|
- $__unixEpochTo() -> 1492750877
