An annotation is an event that is overlayed on top of graphs. The query can have up to four columns per row, the time 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. Format is UTC in seconds, use extract(epoch from column) as "time"
- column with alias: <b>time</b> 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) -&gt; column as "time"
- $__timeEpoch -&gt; extract(epoch from column) as "time"
- $__timeFilter(column) -&gt; column &ge; to_timestamp(1492750877) AND column &le; to_timestamp(1492750877)
- $__unixEpochFilter(column) -&gt; column &gt; 1492750877 AND column &lt; 1492750877
