Actual exam question for Splunk's SPLK-1003 exam
Question #: 84
Topic #: 8
[All SPLK-1003 Questions]

Windows can prevent a Splunk forwarder from reading open files. If files need to be read while they are being written to, what type of input stanza needs to be created?

Show Suggested Answer Hide Answer
Suggested Answer: C

The correct answer is C. MonitorNoHandle.

MonitorNoHandle is a type of input stanza that allows a Splunk forwarder to read files on Windows systems as Windows writes to them. It does this by using a kernel-mode filter driver to capture raw data as it gets written to the file1. This input stanza is useful for files that get locked open for writing, such as the Windows DNS server log file2.

The other options are incorrect because:

A) Tail Reader is not a valid input stanza in Splunk. It is a component of the Tailing Processor, which is responsible for monitoring files and directories for new data3.

B) Upload is a type of input stanza that allows Splunk to index a single file from a local or network file system. It is not suitable for files that are constantly being updated, as it only indexes the file once and does not monitor it for changes4.

D) Monitor is a type of input stanza that allows Splunk to monitor files and directories for new data. However, it may not work for files that Windows prevents Splunk from reading while they are open. In such cases, MonitorNoHandle is a better option2.

A Splunk forwarder is a lightweight agent that can forward data to a Splunk deployment. There are two types of forwarders: universal and heavy. A universal forwarder can only forward data, while a heavy forwarder can also perform parsing, filtering, routing, and aggregation on the data before forwarding it5.

An input stanza is a section in the inputs.conf configuration file that defines the settings for a specific type of input, such as files, directories, network ports, scripts, or Windows event logs. An input stanza starts with a square bracket, followed by the input type and the input path or name. For example, [monitor:///var/log] is an input stanza for monitoring the /var/log directory.

I think "Tail Reader" is for reading logs, but I'm not confident if it applies here. I should have reviewed this more!

I recall that "MonitorNoHandle" was mentioned, but I can't remember if that's the one for open files.

I'm not entirely sure, but I feel like "Monitor" might be the right choice since it sounds familiar from practice questions.

I think we talked about this in class, and I remember something about needing a specific type of input for files that are still being written to.

I'm a little confused by this question. What's the difference between the Monitor and MonitorNoHandle options? I'll have to review my notes to see which one is the right choice here.

Hmm, I'm a bit unsure about this one. I know Windows can cause issues with Splunk forwarders reading open files, but I'm not totally sure which input stanza is the right solution. I'll have to think this through carefully.

This one seems straightforward. I'm pretty sure the answer is Tail Reader, since that's the type of input stanza used to read files that are being actively written to.

Ah, I remember learning about this in the Splunk training. If you need to read files that are being written to, you need to use the Tail Reader input stanza. That's the one that can handle open files.

I'm a bit confused by the wording of some of these options. "Opens up many new design and deployment opportunities" - is that really an advantage of the "one switch at a time" approach? I'm not sure that one applies.

Okay, I think I've got this. The key is to first shut down the database, then mount it and restore the archived logs. After that, I can recover the database and open it with the RESETLOGS option.
