    ><h6>Annotation Query Format</h6>
An annotation is an event that is overlaid on top of graphs. The query can have up to three columns per row, the datetime column is mandatory. Annotation rendering is expensive so it is important to limit the number of rows returned.

- column with the datetime type.
- column with alias: <b>Text</b> or <b>text</b> for the annotation text
- column with alias: <b>Tags</b> or <b>tags</b> for annotation tags. This is should return a comma separated string of tags e.g. 'tag1,tag2'

Macros:
    - $__timeFilter() -&gt; TimeGenerated &ge; datetime(2018-06-05T18:09:58.907Z) and TimeGenerated &le; datetime(2018-06-05T20:09:58.907Z)
    - $__timeFilter(datetimeColumn) -&gt;  datetimeColumn  &ge; datetime(2018-06-05T18:09:58.907Z) and datetimeColumn &le; datetime(2018-06-05T20:09:58.907Z)

    Or build your own conditionals using these built-in variables which just return the values:
    - $__timeFrom -&gt;  datetime(2018-06-05T18:09:58.907Z)
    - $__timeTo -&gt; datetime(2018-06-05T20:09:58.907Z)
    - $__interval -&gt; 5m
