Chronosphere Observability Platform uses the following definitions for licensing units:
  • Active Time Series (ATS) is the total number of unique time series, defined as distinct combinations of metric names and labels, measured within a 2.5 hour time window.
  • Control is the volume of data that undergoes transformation and reshaping. Control is measured in GB for traces, GB for logs, and matched writes for metrics.
  • Long Term Retention is the number of months Chronosphere will retain data at a negotiated resolution.
  • Matched Writes (mW) are the number of writes per second being matched for transformation and reshaping. For more information, see aggregations.
  • Persisted Cardinality is the count of unique time series of the persisted writes stored by Chronosphere. For more information, see persisted cardinality.
  • Persisted Writes Per Minute (WPM) is the total count of individual, timestamped data points persisted in a one-minute interval. For more information, see persisted writes.
  • Persisted Writes Per Second (WPS) is the total count of individual, timestamped data points persisted in a one-second interval.
  • Persistence is the volume of data stored following processing by control. Persistence is measured in GB for traces, GB for logs, WPM for events, and cardinality and resolution for metrics.
  • Raw Retention is the number of days Chronosphere will retain raw data. For more information, see ingestion limits and retention policies.
  • Resolution is the ratio of active time series to persisted writes per second.
  • Time series is a set of data points with matching labels.
