Load balancing on a Universal Forwarder is not scaling correctly. The forwarder's outputs. and the tcpout stanza are setup correctly. What else could be the cause of this scaling issue? (select all that apply)
The possible causes of the load balancing issue on the Universal Forwarder are A and C. The receiving port and the DNS record are both factors that affect the ability of the Universal Forwarder to distribute data across multiple receivers. If the receiving port is not properly set up to listen on the right port, or if the DNS record used is not set up with a valid list of IP addresses, the Universal Forwarder might fail to connect to some or all of the receivers, resulting in poor load balancing.
A non-clustered Splunk environment has three indexers (A,B,C) and two search heads (X, Y). During a search executed on search head X, indexer A crashes. What is Splunk's response?
This is explained in the Splunk documentation1, which states:
If an indexer goes down during a search, the search head notifies you that the results might be incomplete. The search head does not attempt to re-run the search on another indexer.
Which forwarder type can parse data prior to forwarding?
https://docs.splunk.com/Documentation/Splunk/latest/Forwarding/Typesofforwarders
'A heavy forwarder parses data before forwarding it and can route data based on criteria such as source or type of event.'
Which of the following accurately describes HTTP Event Collector indexer acknowledgement?
https://docs.splunk.com/Documentation/Splunk/8.2.2/Data/AboutHECIDXAck
- Section: About channels and sending data
Sending events to HEC with indexer acknowledgment active is similar to sending them with the setting off. There is one crucial difference: when you have indexer acknowledgment turned on, you must specify a channel when you send events. The concept of a channel was introduced in HEC primarily to prevent a fast client from impeding the performance of a slow client. When you assign one channel per client, because channels are treated equally on Splunk Enterprise, one client can't affect another. You must include a matching channel identifier both when sending data to HEC in an HTTP request and when requesting acknowledgment that events contained in the request have been indexed. If you don't, you will receive the error message, 'Data channel is missing.' Each request that includes a token for which indexer acknowledgment has been enabled must include a channel identifier, as shown in the following example cURL statement, where <data> represents the event data portion of the request
When are knowledge bundles distributed to search peers?
'The search head replicates the knowledge bundle periodically in the background or when initiating a search. ' 'As part of the distributed search process, the search head replicates and distributes its knowledge objects to its search peers, or indexers. Knowledge objects include saved searches, event types, and other entities used in searching accorss indexes. The search head needs to distribute this material to its search peers so that they can properly execute queries on its behalf.'
