Monitoring flow deployments

Process Group KPIs

Process Group KPIs expose the metrics that NiFi provides for the process groups. Choosing Process Group enables you to set alerts based on any of the process group metrics that the data flow monitors.

Metric name: Bytes Queued: Metric unit: Bytes; Meaning: How much data is queued, in total, in queues of the selected process group?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated data queued for the selected process group is either more than what is specified in the upper boundary or less than what is specified in the lower boundary for the given time period.
Metric name: Bytes Received: Metric unit: Bytes; Meaning: How much data is received by the selected process group within the flow?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated data received by the selected process group is either below the specified lower threshold or above the upper threshold for the given time period.
Metric name: Bytes Sent: Metric unit: Bytes; Meaning: How much data is sent by the selected process group within the flow?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated data sent by the selected process group is either below the specified lower threshold or above the specified upper threshold for the given time period.
Metric name: Flowfiles Input: Metric unit: Count; Meaning: How many flowfiles are received by the selected process group within the flow?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated number of flowfiles received by the selected process group is either below the specified lower threshold or above the specified upper threshold for the given time period.
Metric name: Flowfiles Out: Metric unit: Count; Meaning: How many flowfiles are sent by the selected process group within the flow?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated number of flowfiles sent by the selected process group is either below the specified lower threshold or above the specified upper threshold for the given time period.
Metric name: Flowfiles Queued: Metric unit: Count; Meaning: How many flowfiles are queued, in total, in queues for the selected process group?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated number of flowfiles queued for the selected process group is either higher than what is specified in the upper boundary or less than what is specified in the lower boundary for the given time period.
Metric name: Flowfiles Received: Metric unit: Count; Meaning: How many flowfiles are received from a source that is external to the flow?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated number of flowfiles received from a source that is external to the flow is either above the specified in the upper boundary or below the specified in the lower boundary.
Metric name: Flowfiles Sent: Metric unit: Count; Meaning: How many flowfiles are sent to an external recipient?; Threshold: Upper and lower boundary; You can use this KPI to create alerts when the aggregated number of flowfiles sent to an external recipient is either above the specified in the upper boundary or below the specified in the lower boundary.
