An annotation is an event that is overlayed on top of graphs. The query can have up to four 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.
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 (in UTC), as a unix time stamp or any sql native date datatype.
- 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'
- column with alias: <b>time</b> for the annotation event time (in UTC). Use unix timestamp in seconds 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'.
