The metadata command is a generating command, which means it is the first command in a search. For those not fully up to speed on Splunk, there are certain fields that are written at index time.Jul 31, 2017

What happens when the Splunk platform indexes raw data?

When the Splunk platform indexes raw data, it transforms the data into searchable events. source A default field that identifies the source of an event, that is, where the event originated. sourcetype A default field that identifies the data structure of an event.

What is source in Splunk?

The repository for data. When the Splunk platform indexes raw data, it transforms the data into searchable events. source A default field that identifies the source of an event, that is, where the event originated. sourcetype A default field that identifies the data structure of an event.

How do I use the metadata command?

The metadata command does not have a lot of options to it, but you can narrow down the search to specific indexes, search peers or server groups and even sourcetypes (like I did above). Once you have a result set, you can flex your SPL muscles on the results to get additional information out it.

What are index time fields in Splunk events?

For those not fully up to speed on Splunk, there are certain fields that are written at index time. These fields are _time, source (where the event originated; could be a filepath or a protocol/port value), sourcetype (type of machine data) and host (hostname or IP that generated an event).

What is called metadata?

Metadata can be explained in a few ways: Data that provide information about other data. Metadata summarizes basic information about data, making finding & working with particular instances of data easier. Metadata can be created manually to be more accurate, or automatically and contain more basic information.

What are the types supported by metadata in Splunk?

Investigation & Forensics.Security Analytics (SIEM)Unified Security Operations.Automation & Orchestration.Security Incident Response.

What are the default fields of Splunk event?

default field Three important default fields are host, source, and source type, which describe where the event originated.

What is Splunk connect?

Splunk Connect for Syslog is a containerized Syslog-ng server with a configuration framework designed to simplify getting syslog data into Splunk Enterprise and Splunk Cloud.

What is source type in Splunk?

source type A default field that identifies the data structure of an event. A source type determines how Splunk Enterprise formats the data during the indexing process. Example source types include access_combined and cisco_syslog .

What is a Splunk index?

"A Splunk index is a repository for Splunk data." Data that has not been previously added to Splunk is referred to as raw data. When the data is added to Splunk, it indexes the data (uses the data to update its indexes), creating event data. Individual units of this data are called events.

What is host in Splunk?

You use the host field in searches to narrow the search results to events that originate from a specific device. You can configure host values for events when events are input into Splunk Enterprise. You can set a default host for a Splunk Enterprise server, file, or directory input.

What are the 4 types of metadata?

Descriptive MetadataUnique identifiers (such as an ISBN)Physical attributes (such as file dimensions or Pantone colors)Bibliographic attributes (such as the author or creator, title, and keywords)

What are the 3 types of metadata?

Metadata Types There are three main types of metadata: descriptive, administrative, and structural. Descriptive metadata enables discovery, identification, and selection of resources.

What are the three major types of metadata in a data warehouse?

Metadata in a data warehouse fall into three major categories: Operational Metadata. Extraction and Transformation Metadata. End-User Metadata.

What is meta data and its type?

Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification.

Setting Up Span Metadata Obfuscation

Span Metadata Obfuscation can be extremely useful when you’re using auto-instrumentation to get traces from your code. This could include an agent running alongside your code, such as a Java agent running in a Spring application or a Python agent in your Django client. Or you may have tracing enabled for third-party code, such as a database.

Removing Span Tags

The Smart Gateway is also able to completely remove tags from a span. For example, if you decided that obfuscating the Jaeger client version wasn’t enough, and that you didn’t want the jaeger.version tag at all, you could add a RemoveSpanTags config.

Protecting Your Data Inside the Smart Gateway

When the Smart Gateway ingests a span, it obfuscates or removes the configured tags as one of the first steps in the processing pipeline. This means that the Smart Gateway cannot use any of the configured tags as it processes your span, including generating internal metrics or making retention decisions.

Specifying pip dependencies

You can specify the Python modules that the platform installs during the app installation. See the following example for the format of this dictionary:

Configuration Section

In order to run an action, an app must operate on an asset that has been configured by the end user within . First, the platform must have one or more instances of an asset configured; at least one that is directly supported by the app, and that matches the vendor and product that the app supports.

README file

An app author can bundle a readme.html file in the app directory, which the platform renders as part of the app documentation. It is rendered between the app description and the asset configuration parameters.

Place Holder Data Type

The order key allows an app author to specify the order in which the controls are displayed to the user. In order to insert a blank, no control, at a specific location use the ph data_type with the order key. For example, to display a blank space between the first and second control define the configuration as shown in the following example:

Actions Section

The actions key defines an array of actions that this app supports. This exposes the core functionality that the app makes available to .

Naming Actions

Splunk SOAR users are used to a particular naming convention for action names. To aid user's understanding, it helps to reuse action names. The following tips can help you understand how to best name actions:

Action Section: Versions

The versions key specifies which versions of the product that this action supports. This key contains a regular expression that is matched against a configured asset to find the app and action within that app that best supports a specific asset.
