----------------------------------
Summary: Add ability to report all component metrics to Prometheus
Key: NIFI-6352
URL: https://issues.apache.org/jira/browse/NIFI-6352
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Matt Burgess
Assignee: Matt Burgess
Fix For: 1.10.0
NIFI-5435 offered a new reporting task that lets Prometheus scrape metrics from
NiFi. The initial contribution included rollup metrics for the root process
group.
This Jira proposes to add options for the granularity of metrics reporting,
namely:
- Root Process Group rollup (the current capability)
- All Process Groups (parent/child PGs but no individual components)
- All Components (ports, connections, processors, etc.)
The "All Components" option is akin to what the SiteToSiteStatusReportingTask
makes available today.
Note that the original process group gauges sometimes apply to other components
as well, so some renaming of gauges and/or properties might need to be done.
Filtering on component type can be done by Prometheus (if All Components is
specified)
