Use Control Center to query data across caches, monitor performance metrics, define and track production alerts, take snapshots for backup and recovery, and collect and analyze API traces. The latest Control Center release, 2025.2, includes a number of new features, as well as improvements and issue resolutions. ## Major Changes ### GridGain 9 Support Scope Change With this release, GridGain Control Center supports GridGain 9 versions 9.0.17 and later and Apache Ignite 3.0.0. GridGain 9.0.16 and earlier are no longer supported. You need to update [Cloud Connector](/docs/tools/enterprise/control-center/gg9/cloud-connector/connect-cloud-connector.md) to the latest version to securely connect your GridGain 9 and Apache Ignite 3 clusters to Control Center. ## New Features ### Code Deployment in GridGain 9 With this release, [code deployment](/docs/tools/enterprise/control-center/gg9/deployment/code-deployment-gg9.md) is now supported for GridGain 9 clusters, further improving you [computing jobs](https://www.gridgain.com/docs/gridgain9/latest/developers-guide/compute/compute) on GridGain 9 clusters. ### Query Monitoring Improvements This release features multiple improvements to query monitoring, focused on improving user experience and usability. With the continued effort to support GridGain 9, you can now also monitor currently running queries in the [Queries](/docs/tools/enterprise/control-center/gg9/querying-gg9.md) screen for you GridGain 9 clusters. ### FST For Specific Data Center Starting with this release, you can specify the data center ID when you start [Data Center Replication](https://www.gridgain.com/docs/latest/administrators-guide/data-center-replication/introduction) for your GridGain 8 cluster from the [Caches](/docs/tools/enterprise/control-center/gg8/caches/caches.md) screen. ### Monitoring improvements This release features multiple improvements to monitoring your clusters: * Attached GridGain 8 clusters now have alerting enabled by default. The `ignite.longJVMPausesCountChange` metric is monitored for never being over 0 milliseconds. * Cluster health widget now tracks if some nodes in the GridGain 8 cluster are offline, and provides the ID of nodes that are offline. ignite.longJVMPausesCountChange * You can now manage what data is collected from GridGain 9 or Apache Ignite 3 clusters from Control Center interface without updating your cluster configuration. ### Strict Table Limitations You can now set strict limits to the data stored by Control Center on your machine by enabling the `control.repositories.limit.strict-mode.enabled` property to `true`. ## Improvements and Fixed Issues ### Control Center Changes | Issue ID | Category | Description | | -------- | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------- | | CC-11100 | General | Updated spring-security from version 6.4.5 to version 6.4.6. | | CC-11084 | General | Updated Spring framework from version 6.2.6 to version 6.2.7. | | CC-10938 | Queries | Control Center now correctly cancels hanged queries. | | CC-10893 | General | You can now see the number of selected rows on "Caches" screen. | | CC-10854 | Queries | The select 100 rows command now works for custom schemas for GridGain 9 and Apache Ignite 3 clusters. | | CC-10801 | General | Updated Spring boot from version 3.4.3 to version 3.4.5. | | CC-10776 | General | Fixed an issue that could cause an ambiguous URI error after creating a deployment unit. | | CC-10749 | Monitoring | GridGain 8.x services now can be stopped from "System view" widget for "Services". | | CC-10724 | General | You can now deploy your code to GridGain 9 clusters. | | CC-10711 | Authentication | For Ignite 2 and GridGain 8 clusters, Control Center now shows what action triggered cluster authorization dialog. | | CC-10710 | Queries | SQL query tab now shows the currently running SQL statement. | | CC-10700 | General | Updated internal GridGain version to 8.9.20. | | CC-10696 | General | You can now see the total number of caches in the Caches screen. | | CC-10694 | General | Control Center now detects hanged actions and aborts them. | | CC-10670 | Metrics | The jvm.gc.CollectionTime metric now correctly uses milliseconds to display duration. | | CC-10660 | General | Improved connection template for GridGain 9 managed clusters. | | CC-10639 | Metrics | You can now flip columns and rows in the "Metrics (table)" widget. | | CC-10638 | Monitoring | Fixed an issue that caused the SQL query widget name to change after changing the query. | | CC-10637 | Cluster Data Replication | You can now choose data center ID when starting FST. | | CC-10629 | General | Control Center now displays history for running queries for 3.x/9.x clusters when cluster is offline or has running queries disabled. | | CC-10617 | Clusters | You can now manage monitoring configuration for GridGain 9 and Apache Ignite 3 clusters from Control Center. | | CC-10609 | Queries | Slightly improved SQL syntax highlighting. | | CC-10565 | General | Added a new strict mode for table size cleanup. | | CC-10516 | Queries | Improved the way results are displayed for the EXPLAIN PLAN FOR SQL statement. | | CC-10513 | General | Added AI3/GG9 "Code deployment" support to Control Center | | CC-10117 | Metrics | Cluster health widget for GridGain 9 and Apache Ignite 3 now checks active alerts. | | CC-10059 | Clusters | Secured GridGain 9 clusters now show a lock icon. | | CC-9850 | SQL | Caches screen now also provides information about cache size. | | CC-9697 | Clusters | Added support for JSON GridGain 9 licenses. | | CC-9692 | General | Control Center administrator can now remove users with attached clusters, allowing the cluster to be attached to other user. | | CC-8948 | General | Improved performance under high load. | ## Updating to 2025.2 You can update Control Center to 2025.2 from 2022.2 and more recent versions.
