net.opentsdb.meta.Annotation

Annotations are used to record time-based notes about timeseries events. Every note must have an associated start_time as that determines where the note is stored.

Annotations may be associated with a specific timeseries, in which case the tsuid must be configured with a valid TSUID. If no TSUID is provided, the annotation is considered a "global" note that applies to everything stored in OpenTSDB. Global annotations are stored in the rows [ 0, 0, 0, <timestamp>] in the same manner as local annotations and timeseries data.

The description field should store a very brief line of information about the event. GUIs can display the description in their "main" view where multiple annotations may appear. Users of the GUI could then click or hover over the description for more detail including the {@link #notes}field.

Custom data can be stored in the custom hash map for user specific information. For example, you could add a "reporter" key with the name of the person who recorded the note. @since 2.0
