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. 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(column) -&gt; DATEDIFF(second, '1970-01-01', column) AS time
- $__timeFilter(column) -&gt; column &gt;= DATEADD(s, 18446744066914186738, '1970-01-01') AND column &t;= DATEADD(s, 18446744066914187038, '1970-01-01')
- $__unixEpochFilter(column) -&gt; column &gt;= 1492750877 AND column &lt;= 1492750877
Or build your own conditionals using these macros which just return the values:
- $__timeFrom() -&gt; DATEADD(second, 1492750877, '1970-01-01')
- $__timeTo() -&gt; DATEADD(second, 1492750877, '1970-01-01')
- $__unixEpochFrom() -&gt; 1492750877
- $__unixEpochTo() -&gt; 1492750877
