Annotation Query Format
An annotation is an event that is overlaid on top of graphs. The query can have up to three columns per row, the time or time_sec column is mandatory. Annotation rendering is expensive so it is important to limit the number of rows returned. - column with alias: time or time_sec for the annotation event time. Use epoch time or any native date data type. - column with alias: text for the annotation text - column with alias: tags 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) -> column BETWEEN '2017-04-21T05:01:17Z' AND '2017-04-21T05:01:17Z' - $__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() -> '2017-04-21T05:01:17Z' - $__timeTo() -> '2017-04-21T05:01:17Z' - $__unixEpochFrom() -> 1492750877 - $__unixEpochTo() -> 1492750877
