Metrics dictionary

This dictionary defines metrics created by and specific to Chronosphere Observability Platform. These metrics are often included in default dashboards, and you can search for them anywhere you use metrics. These curated metrics can help track basic important information about your Observability Platform instance.

The Chronosphere Health Check dashboard includes links to the Collectors, Usage Dashboard, and Licensing Information dashboards.

Query these metrics as their respective Prometheus type.

Capacity limits

Licensing capacity is based on your telemetry types and usage. The following tables describe metrics used for specific sections of your license.

Chronosphere recommends creating alerts using the existing Capacity Limit metrics, which are also used in the Metrics License Consumption dashboard. Use alerts to be notified when you're close to or over 100% of your license limit and therefore at risk of experiencing drops:

Persisted cardinality

The following metrics apply to persisted cardinality, which is a cumulative measure that calculates the sum of the unique time series of the persisted writes that Observability Platform stores, seen over the last 2.5 hours only.

Metric name	Description
`chrono_metrics_persisted_cardinality_license_limit`	License limit for active persisted time series cardinality.
`chrono_metrics_persisted_cardinality_license_capacity`	Capacity limit for active persisted time series cardinality.
`chrono_metrics_persisted_cardinality_license_consumed`	Consumption of the persisted write cardinality limit by datapoint type.

Query the following metric to understand if data is actively being dropped:

chrono_metrics_persisted_license_dpps_dropped{limit="persisted_cardinality"}

Persisted writes

The following metrics apply to persisted writes, which are writes to the Observability Platform database.

Metric name	Description
`chrono_metrics_persisted_writes_license_dpps_limit`	License limit for persisted write DPPS by datapoint type.
`chrono_metrics_persisted_writes_license_dpps_capacity`	Capacity limit for persisted write DPPS by datapoint type.
`chrono_metrics_persisted_writes_license_dpps_consumed`	Consumption rate in DPPS of persisted write license by datapoint type.

Query the following metric to understand if data is actively being dropped:

chrono_metrics_persisted_license_dpps_dropped{limit="persisted_writes"}

Matched writes

The following metrics apply to matched writes, which are the number of writes per second being matched for transformation and reshaping by the Observability Platform aggregation tier.

Metric name	Description
`chrono_metrics_matched_writes_license_dpps_limit`	License limit for matched write DPPS by datapoint type.
`chrono_metrics_matched_writes_license_dpps_capacity`	Capacity limit for matched write DPPS by datapoint type.
`chrono_metrics_matched_writes_license_dpps_consumed`	Consumption rate in DPPS of matched write license by datapoint type.

Query the following metric to understand if data is actively being dropped:

chrono_metrics_matched_license_dpps_dropped
