New Relic data dictionary

This data dictionary defines some of our default-reported data stored in NRDB and queryable via NRQL. This includes events like Transaction, MobileRequest, and BrowserInteraction, and our Metric, Log, and Span data types. These definitions are also available from our query builder UI by mousing over applicable data type and attribute names.

This dictionary doesn't contain:

  • Data from our infrastructure integrations (for that, see docs for a specific integration)
  • Custom data
  • Detailed integration-specific attributes for Metric data

K8sSchedulerSample

Data source:

This event contains Kubernetes scheduler data.

Attribute nameDefinitionData types
goGoroutines

Number of goroutines that currently exist.

goThreads

Number of OS threads created.

httpRequestDurationMicroseconds_handler_HANDLER_count
count

The number of observed HTTP requests events.

httpRequestDurationMicroseconds_handler_HANDLER_quantile_QUANTILE

The HTTP request latencies in microseconds, per quantile.

httpRequestDurationMicroseconds_handler_HANDLER_sum

The sum of the HTTP request latencies, in microseconds.

leaderElectionMasterStatus

Gauge of if the reporting system is master of the relevant lease, 0 indicates backup, 1 indicates master.

processCpuSecondsDelta
seconds (s)

Difference of the user and system CPU time spent in seconds.

processFdsUtilization

Percentage open file descriptors with respect to the maximum number that can be opened.

processMaxFds

Maximum number of open file descriptors.

processOpenFds

Number of open file descriptors.

processResidentMemoryBytes
bytes (B)

Resident memory size, in bytes.

restClientRequestsDelta_code_CODE_host_HOST_method_METHOD

Difference of the number of HTTP requests, partitioned by status code, method, and host.

restClientRequestsRate_code_CODE_host_HOST_method_METHOD

Rate of the number of HTTP requests, partitioned by status code, method, and host.

schedulerPendingPodsActive
count

Number of pending pods in the active queue (requires k8s v1.23+).

schedulerPendingPodsBackoff
count

Number of pending pods in the backoff queue (requires k8s v1.23+).

schedulerPendingPodsUnschedulable
count

Number of pending pods in the unschedulable queue (requires k8s v1.23+).

schedulerPodPreemptionVictims
count

Number of selected preemption victims.

schedulerPreemptionAttemptsDelta

Difference of the total preemption attempts in the cluster until now.

schedulerScheduleAttemptsDelta_result_RESULT

Difference of the number of attempts to schedule pods, by the result. unschedulable means a pod could not be scheduled, while error means an internal scheduler problem.

schedulerScheduleAttemptsRate_result_RESULT

Rate of the number of attempts to schedule pods, by the result. unschedulable means a pod could not be scheduled, while error means an internal scheduler problem.

schedulerSchedulingDurationSeconds_operation_OPERATION_count

The number of observed events of schedulings split by sub-parts of the scheduling operation.

schedulerSchedulingDurationSeconds_operation_OPERATION_quantile_QUANTILE

Scheduling latency in seconds split by sub-parts of the scheduling operation.

schedulerSchedulingDurationSeconds_operation_OPERATION_sum

The sum of scheduling latency in seconds split by sub-parts of the scheduling operation.
