A customer has been using Splunk for one year, utilizing a single/all-in-one instance. This single Splunk server is now struggling to cope with the daily ingest rate.
Also, Splunk has become a vital system in day-to-day operations making high availability a consideration for the Splunk service. The customer is unsure how to design the new environment topology in order to provide this.
Which resource would help the customer gather the requirements for their new architecture?
The best resource to help the customer gather the requirements for their new architecture is the Splunk Validated Architectures document. This document guides customers through various approved architectures that can meet their requirements, including considerations for scalability and high availability, which are essential for their situation.
The customer has an indexer cluster supporting a wide variety of search needs, including scheduled search, data model acceleration, and summary indexing.
Here is an excerpt from the cluster mater's server.conf:
Which strategy represents the minimum and least disruptive change necessary to protect the searchability of the indexer cluster in case of indexer failure?
The appropriate strategy to protect the searchability of the indexer cluster with the minimum and least disruptive change is to leave the replication factor at 2, increase the search factor to 2, and enable summary replication. Increasing the search factor ensures that there are enough searchable copies of the data, and enabling summary replication will safeguard summary data without requiring a complete overhaul of the system configuration or a more complex multi-site setup. This approach balances protection and minimal disruption to the existing cluster configuration.
What is the primary driver behind implementing indexer clustering in a customer's environment?
The primary driver behind implementing indexer clustering in a customer's environment is to provide higher availability for buckets of data. Indexer clustering ensures that data is replicated across multiple indexers, which enhances the redundancy and availability of the data, thus preventing data loss in case an indexer fails.
In a single indexer cluster, where should the Monitoring Console (MC) be installed?
The Monitoring Console (MC) should be installed on the cluster master node in a single indexer cluster, provided that the load on the master node is within acceptable limits. This centralizes monitoring and is often recommended unless specific conditions dictate otherwise, such as heavy load or SmartStore usage, which might necessitate hosting the MC on a dedicated search head.
A customer has downloaded the Splunk App for AWS from Splunkbase and installed it in a search head cluster following the instructions using the deployer. A power user modifies a dashboard in the app on one of the search head cluster members. The app containing an updated dashboard is upgraded to the latest version by following the instructions via the deployer.
What happens?
When a user modifies a dashboard, the modified version is saved in the 'local' directory, which takes precedence over the 'default' directory where the application updates are stored. Therefore, when the app is upgraded, the updated dashboard will not override the user's modifications, and the user will continue to see their modified version.
