Connection KPIs expose the metrics that NiFi provides for the connection used in the
NiFi data flow. Choosing Connection allows you to set alerts based on any
of the connection metrics that the data flow monitors.
- Metric name: Bytes Queued
- Metric unit: Bytes
- Meaning: How much data is stored in a queue?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the data queued in the selected queue or
connection 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: Percent Full
- Metric unit: Percentage
- Meaning: How much of the queue's capacity is used?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the data queued in the selected queue or
connection 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: Flow Files Queued
- Metric unit: Count
- Meaning: How many flow files are queued in this connection?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the aggregated number of flowfiles queued for the
selected queue or connection 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.
