------------------------------------------
Summary: Lack of page read time metric
Key: IGNITE-18823
URL: https://issues.apache.org/jira/browse/IGNITE-18823
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Currently we have metric for count of pages read, but don't have a metric for
page read time. Time metric could be useful for detecting some hardware level
problems.
For page write we have checkpoint metrics (total pages written, write duration,
fsync duration).
Also page read can be caused by page replacement. Page replacement also can
consume some time (depends on algorithm used) and it coulld be useful to add
this metric too.
