Entire Flow KPIs expose the metrics that NiFi provides for the entire data flow.
Choosing Entire Flow enables you to set alerts based on any of the flow
metrics that the data flow monitors.
- Metric name: Data In
- Metric unit: Bytes/sec
- Meaning: How much data did the entire flow receive from external systems per second?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the aggregated data received for the entire flow
is either below the specified lower threshold or above the upper threshold for the given time
period.
- Metric name: Data Out
- Metric unit: Bytes/sec
- Meaning: How much data did the entire flow send to external systems per second?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the aggregated data sent for the entire flow is
either below the specified lower threshold or above the upper threshold for the given time
period.
- Metric name: Flow Files Queued
- Metric unit: Count
- Meaning: How many flow files are queued in all connections of the flow?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the aggregated number of flowfiles queued for all
connections of the flow 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.
