-----------------------------------------
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.
