------------------------------------
Summary: Export ReconTaskStatus as Prometheus metrics
Key: HDDS-6317
URL: https://issues.apache.org/jira/browse/HDDS-6317
Project: Apache Ozone
Issue Type: Improvement
Components: Ozone Recon
Affects Versions: 1.2.0
Reporter: Kohei Sugihara
Assignee: Kohei Sugihara
Currently Recon does not have a feature to export/show last successful
timestamp about each task; if a {{Recon\{Om,Scm}Task}} is failed, Recon may
display an old summary on the top page.
I assume that Recon already stores timestamps in Derby DB as
{{ReconTaskStatus}} table, and these timestamp are important to check the
health status of Recon itself. So I think it might be convenient and better to
export this as {{/prom}} rather than querying to the DB to get
{{ReconTaskStatus}} table by hand.
