Parallel reduce search processing If you struggle with extremely large high-cardinality searches, you might be able to apply parallel reduce processing to them to help them complete faster. You must have a distributed search environment to use parallel reduce search processing.

According to the Splunk documentation1, to manually specify a character set for an input, you need to set the CHARSET key in the props.conf file. You can specify the character set by host, source, or sourcetype, but not by index.

"You can map either users or groups, but not both. If you are using groups, all users must be members of an appropriate group. Groups inherit capabilities form the highest level role they're a member of." "If your LDAP environment does not have group entries, you can treat each user as its own group."

curl “https://mysplunkserver.example.com:8088/services/collector” \ -H “Authorization: Splunk DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67” \ -d ‘{“event”: “Hello World”}, {“event”: “Hola Mundo”}, {“event”: “Hallo Welt”}’. This is the correct curl command to send multiple events through HTTP Event Collector (HEC), which is a token-based API that allows you to send data to Splunk Enterprise from any application that can make an HTTP request. The command has the following components:

The URL of the HEC endpoint, which consists of the protocol (https), the hostname or IP address of the Splunk server (mysplunkserver.example.com), the port number (8088), and the service name (services/collector).

The header that contains the authorization token, which is a unique identifier that grants access to the HEC endpoint. The token is prefixed with Splunk and enclosed in quotation marks. The token value (DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67) is an example and should be replaced with your own token value.

The data payload that contains the events to be sent, which are JSON objects enclosed in curly braces and separated by commas. Each event object has a mandatory field called event, which contains the raw data to be indexed. The event value can be a string, a number, a boolean, an array, or another JSON object. In this case, the event values are strings that say hello in different languages.

 The setting that allows the configuration of Splunk to allow events to span over more than one line is SHOULD_LINEMERGE. This setting determines whether consecutive lines from a single source should be concatenated into a single event. If SHOULD_LINEMERGE is set to true, Splunk will attempt to merge multiple lines into one event based on certain criteria, such as timestamps or regular expressions. Therefore, option A is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [Configure event line merging - Splunk Documentation]

Adding further clarity and quoting same Splunk reference URL from @giubal"

"To keep configuration settings consistent across peer nodes, configuration files are managed from the cluster master, which pushes the files to the slave-app directories on the peer nodes. Files in the slave-app directories have the highest precedence in a cluster peer's configuration. Here is the expanded precedence order for cluster peers:

1.Slave-app local directories -- highest priority

2. System local directory

3. App local directories

4. Slave-app default directories

5. App default directories

6. System default directory --lowest priority

"Specify how far (how many characters) into an event Splunk software should look for a timestamp." since TIME_PREFIX = ^ and timestamp is from 0-29 position, so D=30 will pick up the WHOLE timestamp correctly.
