Getting data into Cloud Platform

 

To begin onboarding and working with data in Splunk Cloud Platform, review the following general steps. 

  1. Decide on the objective you want to achieve using Splunk Cloud Platform.
  2. Identify the data you need in Splunk Cloud Platform to help you complete that objective. 
  3. After you know the data source, find an add-on in Splunkbase to help you get the data into Splunk Cloud Platform (e.g., Splunk Add-on for Microsoft Windows). 
  4. Install the Splunk Cloud credentials package to allow the forwarder to communicate with Splunk Cloud Platform securely.
  5. Use Splunk Lantern’s security and observability use case libraries to discover new applications for your data.

If you have any questions regarding data onboarding, check out the Getting Data In section in our community or contact your CSM or CSA.

Learning the basics

Use these scripted learning paths to master the basics. You don't have to worry about anything going wrong because these paths use sample datasets, so you can get up-to-speed quickly. 

Understanding getting data in processes

Review the following resources before onboarding your data. 

  • 4 main ways to Get Data In. Watch this Tech Talk to learn about getting data in from any Linux or Windows host, how to create lossless syslog ingress or TCP data ingress over any port from any custom application or use case, and using APIs to send or receive data.
  • What data can I index? The Splunk platform can index any and all IT, streaming, machine, and historical data. To set up indexing, you point Splunk at a data source, fill out information about that source, and then that source becomes a data input. Splunk indexes the data stream and transforms it into a series of events that you can view and search right away, with no structuring necessary.

Onboarding your data

To help guide your data onboarding, check out Splunk's five-step process to build best-practice data onboarding workflows. These guidelines can help you streamline data requests, define the use case, validate data, and properly communicate the availability of new data.

Onboarding documentation for popular data sources: 

Data Manager 

Data Manager is the easiest way to get your AWS, Azure, or GCP data into Splunk. It drastically reduces the time to set up cloud data sources from hours to minutes. Data Manager is native to Splunk Cloud Platform and provides a centralized data ingestion management, monitoring and troubleshooting experience. 

Ingest Actions 

Ingest Actions is a new user interface that enables customers to quickly and easily configure data flows and control the volume, format and destination of data. It is accessible from the Splunk Enterprise and Splunk Cloud Platform Search and Reporting UI as an option in the administrative drop down.

Use Ingest Actions to filter, mask, and route data at ingest and at the edge, using only simple clicks - no writing command lines or hand-writing stanzas in configuration files. This feature allows you to cut through the noise, detangling the data that's mission critical from that which needs to be archived. 

The Ingest Actions page can be found in Splunk Web under Settings > Data > Ingest actions. This feature allows you to dynamically preview and build rulesets using sample data. You simply click to add a new rule, specify what needs to be redacted, and the expression you want to mask it with. 

Common use cases: instantly route data to external S3-compliant destinations for archival or audit purposes, remove sensitive information (PII data, user names, etc.), remove IP addresses, filter DEBUG logs, and much more.

Forwarding your data

Universal forwarders are one of the many ways to collect data in Splunk. They stream data from your machine to a data receiver, which is usually a Splunk index where you store your Splunk data. Universal forwarder streaming lets you monitor data in real time.

The universal forwarder also ensures that your data is correctly formatted before sending it to Splunk. You can also manipulate your data before it reaches the indexes or manually add the data. See the following example diagram:

See Deploy the Universal Forwarder to create this configuration. 

Benefits of the Universal Forwarder

Universal forwarders are highly scalable. Universal Forwarders use significantly less hardware resources than other Splunk products. You can install thousands of them without impacting network performance and cost. The universal forwarder does not have a user interface, which helps minimize resource use.

Forwarders allow metadata tagging, including source, source type, and host. They also provide configurable buffering, data compression, SSL security, and the use of any available network ports.

To get started, download the Universal Forwarder, then review:

Archiving your data

Indexes store the data sent to your Splunk Cloud Platform deployment. You can create, update, delete, and view index properties, modify data retention settings for individual indexes, delete data from indexes, and optimize search performance by managing the number of indexes and the data sources stored in specific indexes. Storage is based on your subscription type. You can also purchase additional data retention capacity.
