Metric data structure

count

✅ New Relic Metric API

❌ New Relic Events to Metrics

✅ Prometheus Remote Write

✅ OpenTelemetry

Measures the number of occurrences of an event. The count should be reset to 0 every time the metric is reported. Examples include cache hits per reporting interval and the number of threads created per reporting interval.

You must specify a value for interval.ms when reporting the count metric type using the Metric API.

The value must be a positive double.

Generally, you want to take the rate of the sum:

From Metric select rate(sum(myMetric), 1 minute) . . .

• sum

cumulativeCount

❌ New Relic Metric API

❌ New Relic Events to Metrics

✅ Prometheus Remote Write

✅ OpenTelemetry

Equivalent to the count type described above, but in addition this gives access to cumulative metric fields. For more on this, see Cumulative metrics.

• sum

distribution

❌ New Relic Metric API

✅ New Relic Events to Metrics (delta only)

✅ Prometheus Remote Write

✅ OpenTelemetry

Tracks the statistical distribution on a numeric attribute. This metric is re-aggregatable. For example, 1-minute data points from 60 minutes can be aggregated into a 1-hour data point, without degradation on accuracy.

This type:

• Supports statistical functions like percentile and histogram, and all functions supported by the summary type.
• Uses the same algorithm as the percentile function.

• percentile
• histogram
• min
• max
• sum
• count
• average

gauge

✅ New Relic Metric API

❌ New Relic Events to Metrics

✅ Prometheus Remote Write

✅ OpenTelemetry

Represents a value that can increase or decrease with time. Examples of gauges include the temperature, CPU usage, and memory.

For example, there is always a temperature, but you are periodically taking the temperature and reporting it.

The value must fit into the range of a Java double.

• latest
• min
• max
• sum
• count
• average

summary

✅ New Relic Metric API

✅ New Relic Events to Metrics

✅ Prometheus Remote Write

✅ OpenTelemetry (legacy)

Used to report pre-aggregated data, or information on aggregated discrete events. A summary includes a count, sum value, min value, and max value. The count value must be positive. Examples include transaction count/durations and queue count/ durations.

You must specify a value for interval.ms when reporting the summary metric type using the Metric API.

• min
• max
• sum
• count
• average

uniqueCount

❌ New Relic Metric API

✅ New Relic Events to Metrics

❌ Prometheus Remote Write

❌ OpenTelemetry (legacy)

Tracks the number of unique values on a string or numeric attribute. This metric is re-aggregatable. For example, 1-minute data points from 60 minutes can be aggregated into a 1-hour data point, without degradation on accuracy.

This type is generated only via the event-to-metrics service.
