Chronosphere Observability Platform uses the following definitions for licensing units across both capacity and consumption models:
  • 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.
  • 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.

​
Consumption definitions

The following definitions apply only to the consumption pricing model that uses partitions and budgets to control your telemetry data usage:
  • Credits are a flexible, fungible unit of currency that you can spend on any telemetry type without needing to renegotiate your contract. Learn more about Credits consumption to understand how credits work in the consumption pricing model.
  • Effective Datapoint Resolution (EDR) represents the average time interval between data points for your time series.
  • Metrics Matched Datapoint is a data point matched for aggregation. One Metrics Matched Datapoint is incurred for each aggregation rule matched for each data point.
  • Metrics Matched Histogram Datapoint Bucket is a bucket within a histogram data point matched for aggregation. One Metrics Matched Histogram Datapoint Bucket is incurred for each non-zero bucket within a matched histogram data point.
  • Metrics Persisted Datapoint is an individual, timestamped data point that’s persisted to storage. Metrics Persisted Datapoints pricing varies by Effective Datapoint Resolution.
  • Metrics Persisted Histogram Datapoint Bucket is a bucket within a histogram data point that’s persisted to storage. One Metrics Persisted Histogram Datapoint Bucket is incurred for each non-zero bucket within a persisted histogram data point.
  • Metrics Persisted Series is a time series, defined as a combination of metric name and labels, that’s persisted to storage. One Metrics Persisted Series is incurred for a time series if no identical time series have been persisted in the last 48 hours. Metrics Persisted Series pricing varies by storage retention.

Capacity definitions

The following definitions apply only to the capacity pricing model that uses quotas and pools to control your telemetry data usage:
  • Matched Writes (mW) are the number of writes per second being matched for transformation and reshaping. For more information, see matched writes.
  • 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.
