" To activate distributed search, you add search peers, or indexers, to a Splunk Enterprise instance that you desingate as a search head. You do this by specifying each search peer manually. "

In Splunk Enterprise and Splunk Universal Forwarder, data inputs are configured using stanzas in inputs.conf . Each stanza defines a listener for a particular input type (for example, TCP or UDP) and a specific port.

Splunk documentation states that a single TCP input stanza can receive data from multiple remote hosts sending to the same TCP port, and similarly, a single UDP input stanza can receive data from multiple devices sending to the same UDP port. Therefore, the number of sending devices does not determine the number of stanzas required; rather, the input protocol and port type do.

In this case:

All three TCP devices can send data to one TCP port (one stanza).

All four UDP devices can send data to one UDP port (one stanza).

Thus, the minimum number of input stanzas required is two — one for TCP and one for UDP.

Example configuration (inputs.conf):

# TCP input for three switches sending via TCP

[tcp://9997]

sourcetype = switch_logs

# UDP input for four switches sending via UDP

[udp://514]

sourcetype = switch_logs

This configuration ensures all seven devices’ logs are collected without creating individual stanzas for each device.

" To set the default username and password, place user-seed.conf in $SPLUNK_HOME/etc/system/local. You must restart Splunk to enable configurations. If the $SPLUNK_HOME/etc/passwd file is present, the settings in this file (user-seed.conf) are not used. "

When creating new user roles in Splunk, it ' s recommended to define roles that incorporate the necessary capabilities and index access permissions. This approach allows for granular control over user access and aligns with best practices for role-based access control.

" You can create custom roles and assign those roles to your users. Custom roles let you make granular adjustments to user access, including... Role inheritance... Capabilities... Allowed and default indexes... "

— About configuring role-based user access -

By creating roles that incorporate both capabilities and index access, administrators can efficiently manage user permissions and maintain a secure Splunk environment.

Specifies a comma-separated list of tcpout group names. Use this setting to selectively forward your data to specific indexers by specifying the tcpout groups that the forwarder should use when forwarding the data. Define the tcpout group names in the outputs.conf file in [tcpout: < tcpout_group_name > ] stanzas. The groups present in defaultGroup in [tcpout] stanza in the outputs.conf file.

The ellipsis wildcard searches recursively through directories and any number of levels of subdirectories to find matches.

If you specify a folder separator (for example, //var/log/.../file), it does not match the first folder level, only subfolders.

* The asterisk wildcard matches anything in that specific folder path segment.

Unlike ..., * does not recurse through subfolders.

" In the input segment, Splunk software consumes data. It acquires the raw data stream from its source, breaks in into 64K blocks, and annotates each block with some metadata keys. "
