> Key: IGNITE-8580
> URL: https://issues.apache.org/jira/browse/IGNITE-8580
> Project: Ignite
> Issue Type: Task
> Components: persistence, sql
> Reporter: Vladimir Ozerov
> Assignee: Yury Gerzhedovich
> Priority: Major
> Fix For: 2.7
>
>
> Currently it is impossible to track how many pages of a certain type were
> read from or written to disk. This might be very useful for performance
> tuning and debugging purposes. E.g. excessive page reads may highlight
> missing SQL index.
> We need to expose total physical read/write, logical read pages metrics
> splitted by aggregate page type DATA, H2, OTHER (see
> org.apache.ignite.internal.processors.cache.persistence.tree.io.PageIO#getType()).
