Splunk SPLK-1003 - Splunk Enterprise Certified Admin

In Splunk Enterprise, when collecting data from remote Windows machines using Windows Management Instrumentation (WMI), the configurations are defined in the wmi.conf file. This file specifies the parameters for connecting to WMI providers and defines the data inputs.

The wmi.conf file is located in the $SPLUNK_HOME\etc\system\local\ directory. It contains stanzas that define global settings and input-specific configurations for WMI data collection. This setup allows Splunk to collect various types of data from remote Windows systems, such as event logs and performance metrics, without requiring a forwarder on the remote machine.

"Where to place the scripts for scripted inputs. The script that you refer to in $SCRIPT can reside in only one of the following places on the host file system:

$SPLUNK_HOME/etc/system/bin

$SPLUNK_HOME/etc/apps//bin

$SPLUNK_HOME/bin/scripts

As a best practice, put your script in the bin/ directory that is nearest to the inputs.conf file that calls your script on the host file system."

 [monitor::/opt/log/crashlog/Jan27crash.txt]. This stanza means that Splunk is monitoring a single local file named Jan27crash.txt in the /opt/log/crashlog/ directory1. The monitor input type is used to monitor files and directories for changes and index any new data that is added2.

The coldPath parameter defines the path for the cold buckets, which are the oldest and least frequently accessed data in an index1. By setting the coldPath to point to the NAS mount point, the Splunk administrator can achieve the retention strategy of having older data on slower NAS storage.

because transforms.conf is the right configuration file to state the regex expression.https://docs.splunk.com/Documentation/Splunk/8.1.0/Admin/Transformsconf

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.

The serverclass.conf file controls how deployment apps and configurations are distributed from the Deployment Server to its Deployment Clients. Within this configuration, attribute values can be defined at multiple levels, and Splunk applies them based on a defined order of precedence — from general to most specific.

The correct order of evaluation (lowest to highest precedence) is:

[global] — applies to all server classes and clients unless overridden.

[serverClass:<name>] — applies to all clients in that specific server class.

[serverClass:<name>:app:<appname>] — applies only to a specific app within that server class and overrides previous settings.

This means that values set in the [serverClass::app:] stanza take priority over those in [serverClass:], which in turn override values in [global].

Example (from serverclass.conf):

[global]

whitelist.0 = *

[serverClass:web_servers]

whitelist.0 = web01*

blacklist.0 = test*

[serverClass:web_servers:app:web_monitoring]

restartSplunkWeb = true

Here, restartSplunkWeb = true in the app stanza overrides any inherited setting from the global or class level.
