> Add metrics for index pages loaded into memory
> ----------------------------------------------
>
> Key: IGNITE-14774
> URL: https://issues.apache.org/jira/browse/IGNITE-14774
> Project: Ignite
> Issue Type: Improvement
> Components: general
> Affects Versions: 2.11
> Reporter: Aleksandr Polovtcev
> Assignee: Aleksandr Polovtcev
> Priority: Minor
> Fix For: 2.11
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Expose the number of index pages currently loaded into memory on per-cache
> group and per-data region basis.
> h3. Implementation details
> # PageMetrics - an aggregation of all page-related metrics. At the moment of
> writing, contains the total number of pages and the number of index pages.
> # DataRegionMetricsImpl now contains page metrics related to every created
> cache group in a form of an immutable copy-on-write IntMap. It also contains
> an aggregation over these metrics that can be used as metrics for the whole
> data region.
> # Index pages allocation is tracked through the PageIO#initNewPage method,
> which can later be used to track other kinds of pages.
> # Index pages de-allocation is tracked in various places like replacing a
> page or adding it to a free list as I couldn’t find a single suitable place
> for this logic.
