Configure the manager node with the dashboard
You can edit the configuration of an existing manager node through its dashboard:
- In Splunk Web, click Settings > Indexer clustering.
The manager node dashboard appears.
In some versions of Splunk Enterprise, the manager node dashboard is labeled as the "master node" dashboard. Aside from the label, the dashboards are identical.
- Select the Edit button on the upper right side of the dashboard.
The Edit button presents several options:
- Node Type. Change the instance's node type. Caution: It is extremely unlikely that you will want to change the node type for nodes in an active cluster. Consider the consequences carefully before doing so.
- Master Node Configuration. Change these manager node settings:
- Replication Factor. Change the cluster's replication factor. Caution: It is inadvisable to increase the replication factor after your cluster contains significant amounts of data. Doing so will kick off a great deal of bucket activity, which will have an adverse effect on the cluster's performance while bucket copies are being created.
- Search Factor. Change the cluster's search factor. Caution: It is inadvisable to increase the search factor after your cluster contains significant amounts of data. Doing so will kick off a great deal of bucket activity, which will have an adverse effect on the cluster's performance while bucket copies are being made searchable.
- Security Key. Change the security key. Only change the security key if you are also changing it for all other nodes in the cluster. The key must be the same across all instances in a cluster.
- Cluster Label. Label the cluster. The label is useful for identifying the cluster in the monitoring console. See Set cluster labels in Securing Splunk Enterprise.
The Master Node Configuration option is disabled for multisite clusters.
- Configuration Bundle Actions. Click Push to distribute the configuration bundle from the manager node to peer nodes. Optionally, validate the bundle and check restart without applying the bundle, or rollback to the previous bundle. See Update common peer configurations and apps.
- Data Rebalance. Rebalance the buckets so that each peer has approximately the same number of bucket copies. See Rebalance the indexer cluster.
- Disable Indexer Clustering. Remove this node from the cluster. Caution: If you remove the manager node from the cluster, the entire cluster will eventually fail.
For information on using this dashboard to enable a manager node initially, see Enable the indexer cluster manager node.
For information on using this dashboard to view cluster status, see View the manager node dashboard.
