Discuss Splunk SPLK-1003 Exam Topic 1 Question 99

Which Splunk component(s) would break a stream of syslog inputs into individual events? (select all that apply)

AUniversal Forwarder

BSearch head

CHeavy Forwarder

DIndexer

Suggested Answer: D

The correct answer is D. The timezone of the forwarder will be added to the event as part of indexing.

According to the Splunk documentation1, Splunk software determines the time zone to assign to a timestamp using the following logic in order of precedence:

Use the time zone specified in raw event data (for example, PST, -0800), if present.

Use the TZ attribute set in props.conf, if the event matches the host, source, or source type that the stanza specifies.

If the forwarder and the receiving indexer are version 6.0 or higher, use the time zone that the forwarder provides.

Use the time zone of the host that indexes the event.

In this case, the event does not have a time zone specified in the raw data, nor does it have a TZ attribute set in props.conf. Therefore, the next rule applies, which is to use the time zone that the forwarder provides. A universal forwarder is a lightweight agent that can forward data to a Splunk deployment, and it knows its system time zone and sends that information along with the events to the indexer2. The indexer then converts the event time to UTC and stores it in the _time field1.

The other options are incorrect because:

A) Universal Coordinated Time (UTC) is not the time zone that Splunk adds to the event as part of indexing, but rather the time zone that Splunk uses to store the event time in the _time field. Splunk software converts the event time to UTC based on the time zone that it determines from the rules above1.

B) The timezone of the search head is not relevant for indexing, as the search head is a Splunk component that handles search requests and distributes them to indexers, but it does not process incoming data3. The search head uses the user's timezone setting to determine the time range in UTC that should be searched and to display the timestamp of the results in the user's timezone2.

C) The timezone of the indexer that indexed the event is only used as a last resort, if none of the other rules apply. In this case, the forwarder provides the time zone information, so the indexer does not use its own time zone1.

Yup, Heavy Forwarder and Indexer for sure!

Paola 11 months ago

Wait, can the Search Head really break events? I’m not so sure.

Ty 11 months ago

Universal Forwarder can also handle that, right?

Loren 11 months ago

I thought the Indexer was the main one for breaking events?

Lai 11 months ago

Definitely the Heavy Forwarder does this!

Hershel 12 months ago

I’m a bit confused about the Search Head's role here. I thought it was more for querying than for breaking up the inputs.

Tamesha 12 months ago

I feel like the Universal Forwarder just sends the data, so it probably doesn't break it into events, right?

Clarinda 12 months ago

I remember practicing a question similar to this, and I think the Heavy Forwarder might also be involved in parsing the data.

Stefany 1 year ago

I think the Indexer is definitely one of the components that breaks the syslog inputs into events, but I'm not sure about the others.

Salena 1 year ago

The Heavy Forwarder might be able to handle this task, since it's designed for more complex data processing. I'll make sure to consider that option as well.

Mari 1 year ago

I'm pretty sure the Indexer is involved in parsing and indexing the data, so that could be a good choice. But I'm not 100% confident on that.

Lezlie 1 year ago

The Universal Forwarder seems like a good option, since it's responsible for collecting and forwarding data. But I'm not sure if it actually breaks the syslog stream into individual events.

Carissa 1 year ago

This is a tricky one. I'll need to think through the different Splunk components and their roles.

Norah 1 year ago

I bet the correct answer is 'D) Indexer' because that's the component that's always in charge of breaking things apart, just like my ex-girlfriend.

Wait, is there an option for 'All of the above'? I feel like Splunk has a way of making everything work together, you know?

Kate 1 year ago

The Indexer makes sense to me. After all, that's where the actual indexing and storage of the events happens, right?

Wilda 1 year ago

↳ replying to Kate

That's correct. The Search head is used for searching and visualizing the indexed data, not breaking it into events.

Jennie 1 year ago

↳ replying to Kate

I think the Universal Forwarder just forwards the data without breaking it into individual events.

Paola 1 year ago

↳ replying to Kate

The Heavy Forwarder can also break a stream of syslog inputs into individual events.

Cassi 1 year ago

↳ replying to Kate

Yes, the Indexer is responsible for indexing and storing the events.

Sherrell 1 year ago

Hmm, the Heavy Forwarder could be a good option too. Isn't that the component that handles a lot of the data processing before sending it to the Indexers?

Julio 1 year ago

C) Heavy Forwarder

A) Universal Forwarder

Tawanna 1 year ago

I'm not so sure about the Search Head - I thought its job was more on the analysis side of things, not the event parsing side.

Rebeca 2 years ago

I believe Indexer can also break the stream of syslog inputs into individual events.

Cordelia 2 years ago

I agree with Luisa, Universal Forwarder and Heavy Forwarder are the components that can break the stream of syslog inputs.

Shawna 2 years ago

The Universal Forwarder seems like the obvious choice here, since it's designed to handle syslog inputs.

Winfred 1 year ago

A) Universal Forwarder

Luisa 2 years ago

I think Universal Forwarder and Heavy Forwarder can break the stream of syslog inputs.
