Subject [jira] [Created] (IGNITE-12550) Add page read latency histogram per data region
Date Thu, 16 Jan 2020 12:37:00 GMT
Alexey Goncharuk created IGNITE-12550:
-----------------------------------------

             Summary: Add page read latency histogram per data region
                 Key: IGNITE-12550
                 URL: https://issues.apache.org/jira/browse/IGNITE-12550
             Project: Ignite
          Issue Type: Improvement
          Components: persistence
            Reporter: Alexey Goncharuk
            Assignee: Alexey Goncharuk
             Fix For: 2.9


During an incident I experienced a large checkpoint mark duration. It was impossible to determine
whether this was caused by a stalled disk because of large number of long page reads or by
some other reasons.
Having a metric showing the page read latency histogram would help in such cases.
