A Splunk Enterprise trial license gives you access to all the features of Splunk Enterprise for a limited period of time, usually 60 days1. After the trial period expires, you can either purchase a Splunk Enterprise license or switch to a Free license1.

A Splunk Enterprise Free license allows you to index up to 500 MB of data per day, but some features are disabled, such as authentication, distributed search, and alerting2. You can switch to a Free license at any time during the trial period or after the trial period expires1.

A Splunk Enterprise Forwarder license is used with forwarders, which are Splunk instances that forward data to other Splunk instances. A Forwarder license does not allow indexing or searching of data3. You can install a Forwarder license on any Splunk instance that you want to use as a forwarder4.

A Splunk Enterprise commercial end-user license is a license that you purchase from Splunk based on either data volume or infrastructure. This license gives you access to all the features of Splunk Enterprise within a defined limit of indexed data per day (volume-based license) or vCPU count (infrastructure license). You can purchase and install this license after the trial period expires or at any time during the trial period1.

The splunk server field contains the name of the Splunk server containing the event. Useful in a distributed Splunk environment. Example: Restrict a search to the main index on a server named remote. splunk_server=remote index=main 404

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.

The deployer is a Splunk Enterprise instance that you use to distribute apps and certain other configuration updates to search head cluster members. The set of updates that the deployer distributes is called the configuration bundle.https://docs.splunk.com/Documentation/Splunk/8.1.3/DistSearch/PropagateSHCconfigurationchanges#:~:text=The%20deployer%20is%20a%20Splunk,is%20called%20the%20configuration%20bundle.

First line says it all: " The deployment server distributes deployment apps to clients. "

Hot/warm/cold/thawed bucket types are searchable. Frozen isn ' t searchable because its either deleted at that state or archived.

The app local directories move to second in the priority list. This is explained in the Splunk documentation, which states:

In a clustered environment, the precedence of configuration files changes slightly from that of a standalone deployment. The app local directories move to second in the priority list, after the peer-apps local directory. This means that any configuration files in the app local directories on the individual peers are overridden by configuration files of the same name and type in the peer-apps local directory on the master node.

" Every Splunk instance has a fishbucket index, except the lightest of hand-tuned lightweight forwarders, and if you index a lot of files it can get quite large. As any other index, you can change the retention policy to control the size via indexes.conf "

Splunk uses alayered configuration modelwhere settings are loaded in a specific order. This order determines which configuration takes precedence when multiple settings conflict. Atindex time(the point when data is parsed and indexed), the configuration precedence is clearly defined in the official documentation.

FromSplunk Docs(props.conf precedence):

Configuration file resolution order (highest to lowest precedence):

$SPLUNK_HOME/etc/users/ < username > / < appname > /local

$SPLUNK_HOME/etc/apps/ < appname > /local

$SPLUNK_HOME/etc/apps/ < appname > /default

$SPLUNK_HOME/etc/system/local

$SPLUNK_HOME/etc/system/default

However, forindex-time configurations, a slight difference applies:

system/local and users/local areoften treated specially, butin practice and according to Splunk Docs, thesystem/localconfigs override apps/default, and so on.

InOption C, the correct precedence fromhighest to lowestis:

/etc/users/local (Highest)

/etc/system/default

/etc/apps/aaa/local

/etc/apps/zzz/default

/etc/system/local (Lowest of these listed)

Though system/local typically has high precedence,when users/local is involved, that is the ultimate override. Splunk Docs confirms this in:

Configuration file precedence

Configuration layering reference

Therefore, Option C reflects the correct Splunk configuration file precedence order at index time.
