Splunk SPLK-2002 Exam With Confidence Using Practice Dumps

According to Splunk Enterprise Distributed Clustering documentation, when you add a search head to an indexer cluster, you must configure it to communicate with the Cluster Manager (previously known as Master Node). The proper way to initialize this connection is by editing the cluster configuration using the splunk edit cluster-config command.

The correct syntax for a search head is:

splunk edit cluster-config -mode searchhead -manager_uri :8089 -secret

Here:

-mode searchhead specifies that this node will function as a search head that participates in distributed search across the indexer cluster.

-manager_uri provides the management URI of the cluster manager.

-secret defines the shared secret key used for secure communication between the manager and cluster members.

Once this configuration is applied, the search head must be restarted for the changes to take effect.

Using -mode peer (Option B) is for indexers joining the cluster, not search heads. The add cluster-manager command (Options C and D) is not a valid Splunk command.

The license_usage.log file is generated and maintained on the License Manager node in a Splunk deployment. This log provides detailed statistics about daily license consumption, including data volume indexed per pool, index, sourcetype, source, and host.

In a distributed or clustered environment (with both search head and indexer clusters), the License Manager acts as the central authority that collects license usage information from all indexers and consolidates it into this log. The License Manager receives periodic reports from each license peer (indexer) and records them in:

$SPLUNK_HOME/var/log/splunk/license_usage.log

The log is automatically indexed into the _internal index with sourcetype=splunkd and can be queried using searches such as:

index=_internal source=*license_usage.log* type="RolloverSummary"

Other components like the Cluster Manager, SHC Deployer, or individual indexers do not store the full consolidated license usage data — they only send summarized reports to the License Manager.

Therefore, the License Manager is the definitive and Splunk-documented location for retrieving and analyzing license_usage.log data across a distributed deployment.

The following logs are included in the _introspection index, which contains data that the Splunk Enterprise deployment logs for platform instrumentation:

disk_objects.log. This log contains information about the disk objects that Splunk creates and manages, such as buckets, indexes, and files. This log can help monitor the disk space usage and the bucket lifecycle.

resource_usage.log. This log contains information about the resource usage of Splunk processes, such as CPU, memory, disk, and network. This log can help monitor the Splunk performance and identify any resource bottlenecks. The following logs are not included in the _introspection index, but rather in the _internal index, which contains data that Splunk generates for internal logging:

audit.log. This log contains information about the audit events that Splunk records, such as user actions, configuration changes, and search activity. This log can help audit the Splunk operations and security.

metrics.log. This log contains information about the performance metrics that Splunk collects, such as data throughput, data latency, search concurrency, and search duration. This log can help measure the Splunk performance and efficiency. For more information, see About Splunk Enterprise logging and [About the _introspection index] in the Splunk documentation.
