Monitor Tab

The Monitor tab provides real-time tracking of replication progress for topics, consumer groups, and schemas. It is the primary interface for assessing cutover readiness and managing individual component states during an active migration.

Cutover Readiness

The top section displays an overall cutover readiness summary:

Metric	Description
Completion Percentage	Aggregate progress toward cutover readiness
Topics Synced	Number of topics that have reached “In Sync” status
Consumer Groups Ready	Number of consumer groups with synchronized offsets
Schemas Synced	Number of schema subjects replicated to the destination
Last Updated	Timestamp of the most recent status refresh

Overall Migration Statuses

Status	Description
Not Ready for Cutover	No replication activity initiated (displayed with an error color)
Migration In Progress	Active migration with some components still syncing
In Sync	All monitored components have caught up with the source
Ready	All components in sync, ready for cutover
Cutover Done	Cutover complete for all components

Topics

The Topics sub-tab displays all selected topics with their synchronization status.

Each topic row shows:

• Topic Name: Fully qualified name
• Partitions: Number of partitions
• Sync Progress Bar: Visual indicator of replication completeness
• Status Badge: Current replication state

Expand a topic row to view partition-level details:

Field	Description
Partition Number	Partition ID within the topic
Source Offset	Latest offset on the source cluster
Destination Offset	Latest offset on the destination cluster
Lag	Number of messages behind (source minus destination)
Status	Per-partition replication state

Topic Statuses

Status	Description
Not Started	No replication activity for this topic
Sync In Progress	Data is actively being replicated
In Sync	All available messages have been replicated
Producer Cutover	Producers have been redirected to the destination

Partition Statuses

Status	Description
Syncing	Partition data is actively being replicated
In Sync	Partition offsets are aligned between source and destination
Cutover	Partition cutover is complete

Users can remove a topic from the migration or rollback a topic that has been cut over.

Consumer Groups

The Consumer Groups sub-tab displays all selected consumer groups with their offset synchronization progress.

Each consumer group row shows:

• Consumer Group ID: Unique identifier
• Partitions: Total partitions consumed
• Sync Progress: Visual indicator of offset synchronization
• Status: Current synchronization state

Expand a consumer group row to view partition-level offset details, including source offset, destination offset, and lag for each partition.

Consumer Group Statuses

Status	Description
None	No status assigned
Not Started	Offset synchronization has not begun
Sync In Progress	Offsets are actively being synchronized
In Sync	All offsets are aligned between source and destination
Consumer Cutover	Consumers have been redirected to the destination

Users can exclude a consumer group from the migration if it is no longer needed.

Schemas

The Schemas sub-tab displays all selected schema subjects with their synchronization status.

Each schema row shows:

Field	Description
Subject	Schema subject name
Type	Serialization format (JSON, AVRO, PROTOBUF)
Source Version	Current version on the source registry
Destination Version	Current version on the destination registry
Status	Synchronization state

Schema Statuses

Status	Description
Syncing	Schema replication is in progress
Synced	Schema versions match between source and destination
Version Mismatch	Source and destination have different version counts
Missing Dest	Schema exists on source but not on destination
Extra Dest	Schema exists on destination but not on source

Manage Topics

The Manage Topics sub-tab allows you to add topics to an in-progress migration job.

Summary counters:

Metric	Description
Total Topics	All topics on the source cluster
Mirrored	Topics already included in the migration
Available to Add	Topics eligible to be added

Topics with naming conflicts on the destination are shown as inline warnings within the table, not as a separate counter.

The table displays each topic with:

Column	Description
Topic Name	Fully qualified name
Partitions	Number of partitions
Replication Factor	Number of replicas
Actions	Add (for available topics) or Conflicting (for topics with conflicts)

Manage CGs

The Manage Consumer Groups sub-tab allows you to add consumer groups to an in-progress migration job.

Summary counters:

Metric	Description
Total Groups	All consumer groups on the source cluster
Replicated	Groups already included in the migration
Available to Add	Groups eligible to be added

The table displays each group with:

Column	Description
Consumer Group ID	Unique identifier
Topics	Subscribed topics
Actions	Add (for available groups) or Exclude (for groups currently being mirrored)

Manage Schemas

The Manage Schemas sub-tab is available when schema management is enabled for the migration job. It allows you to add schema subjects to an in-progress migration.

Summary counters:

Metric	Description
Total Schemas	All schema subjects on the source registry
Mirrored	Subjects already included in the migration
Available to Add	Subjects eligible to be added

The table displays each schema subject with:

Column	Description
Subject	Schema subject name
Type	Serialization format (JSON, AVRO, PROTOBUF)
Versions	Number of versions for the subject
Actions	Add (for available subjects) or Exclude (for subjects currently being mirrored)

Tip

You can add topics and consumer groups while the job is in progress. The suite begins monitoring the newly added components without interrupting the existing replication.

Caution

Removing a topic from a running migration does not delete the replicated data on the destination cluster. It only stops monitoring and excludes the topic from cutover readiness calculations.

Sync Resources (Replicator Pre-create)

Sync Resources is available on the Monitor page for running Replicator jobs that use Pre-create topic creation mode. It is not offered for auto-create migrations, where Replicator owns topic creation.

In Pre-create mode, Replicator does not create destination topics itself — the suite creates them before the connector starts. If a new source topic appears after the job has started (for example, a wildcard pattern matches a newly-created topic), use Sync Resources to create it on the destination without stopping the migration.

What Sync Resources does

1. Re-resolves the migration’s topic selection — including wildcard patterns — against the live source cluster.
2. Creates any source topics that are missing on the destination, with the same partition count and config exclusions applied at job start.
3. Leaves topics that already exist on the destination unchanged.
4. After creation, replication to the newly-created topic begins automatically and data appears on it.

Sync Resources report

After triggering, a Topic Pre-creation Report modal shows the per-topic outcome:

Status	Description
Created	Topic was newly created on the destination.
Skipped	Topic was already present on the destination; left unchanged.
Failed	Topic could not be created; the topic name and reason are shown.

The report is also accessible at any time via the View sync report button on the Monitor page.

Note

Sync Resources is available only for running Pre-create migrations. It is not offered for auto-create migrations, where Replicator controls topic creation.

Caution

In Pre-create mode, ongoing configuration changes on an existing source topic are not automatically pushed to the destination topic. Sync Resources creates missing topics only — it does not modify configurations on already-existing destination topics.
