Surkov Aleksandr reassigned IGNITE-12183:
-----------------------------------------
Assignee: Surkov Aleksandr (was: Maxim Muzafarov)
> Move rebalanceKeysReceived metric to the cache group level
> ----------------------------------------------------------
>
> Key: IGNITE-12183
> URL: https://issues.apache.org/jira/browse/IGNITE-12183
> Project: Ignite
> Issue Type: Improvement
> Reporter: Aleksandr Brazhnikov
> Assignee: Surkov Aleksandr
> Priority: Major
> Labels: IEP-35
>
> Currently, `onRebalanceKeyReceived` metric is treated as CacheMetric, but,
> for example, calculated for the whole cache group for historical rebalance
> (see IGNITE-11330 and code block comment below). So, it is not actually
> working as CacheMetric. We should move it to the cache group level.
> Also, such metrics `EstimatedRebalancingKeys`, `RebalancedKeys`,
> `RebalancingKeysRate` can be available without enabling cache statistics.
> {code}
> /**
> * Update rebalancing metrics.
> */
> private void updateGroupMetrics() {
> // TODO: IGNITE-11330: Update metrics for touched cache only.
> // Due to historical rebalancing "EstimatedRebalancingKeys" metric is
> currently calculated for the whole cache
> // group (by partition counters), so "RebalancedKeys" and
> "RebalancingKeysRate" is calculated in the same way.
> for (GridCacheContext cctx0 : grp.caches()) {
> if (cctx0.statisticsEnabled())
> cctx0.cache().metrics0().onRebalanceKeyReceived();
> }
> }
