Name Description
merge-columns Merge multiple series into a single row using a boolean expression or enumerated columns as a grouping key.
Example:
  • merge-columns = entity
  • merge-columns = entity, tags
  • merge-columns = tags.target
  • merge-columns = a.tags.country == b.tags.country


hide-empty-series Hide series for which no data exists or data whose validity is expired.
Possible values: false, true.
Default value: true.
Example: hide-empty-series = false

Row Object

The series table consists of multiple rows. In a basic configuration, each row represents one series and provides access to the following fields:

  • alias: string - series alias
  • config: object - parsed portal config
  • data: object - {t:[], v:[]}, timestamps and corresponding values
  • last: object - {t:<integer>, v:<number>}, last timestamp and corresponding value
  • lastIntv: array - array of last two timestamps

If merge-columns is enabled, the row contains multiple series comprising the following fields:

  • aliases: object - {alias: series}, object with key:value pairs, where keys are series aliases, and values are corresponding series objects, which fields are listed above

  • map: object - similar to aliases, but the key depends on merge-columns value:

    merge-columns Key map object
    entity Metric name {metric_name:series}
    metric Entity name {entity_name:series}
    Other value - {} -

WARNING

aliases and map cannot be used simultaneously: if [series] contains alias it is not added to map.
