System KPIs expose the metrics that NiFi provides for the system. Choosing
System allows you to set alerts based on any of the system metrics that
the data flow monitors.
- Metric name: CPU Utilization
- Metric unit: Percentage
- Meaning: How much of the available CPU to the entire cluster is being used by
deployment?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the CPU utilization is either above the specified
upper threshold or below the specified lower threshold for the given time period. For
example, if the threshold is 80% and the time period is 5 minutes, all data points that
are being captured within five minutes must show a higher utilization than 80%, to trigger
an alert.
- Metric name: Core Allocation
- Metric unit: Count
- Meaning: How many cores are allocated?
- Threshold: Upper and lower boundary
- You can use this KPI to create alerts when the core allocation is either above the specified
upper threshold or below the specified lower threshold for the given time period.
