Splunk Architecture is a topic which will make its way into any set of Splunk interview questions. As explained in the previous question, the main components of Splunk are: Forwarders, Indexers and Search Heads. You can then mention that another component called Deployment Server(or Management Console Host) will come into the picture in case of a larger environment. Deployment servers:
This kind of question is asked to understand the scope of your knowledge. You can answer that question by saying that Splunk has a lot of competition in the market for analyzing machine logs, doing business intelligence, for performing IT operations and providing security. But, there is no one single tool other than Splunk that can do all of these operations and that is where Splunk comes out of the box and makes a difference. With Splunk you can easily scale up your infrastructure and get professional support from a company backing the platform. Some of its competitors are Sumo Logic in the cloud space of log management and ELK in the open source category. You can refer to the below table to understand how Splunk fares against other popular tools feature-wise.
You can say that the benefits of getting data into Splunk via forwarders are bandwidth throttling, TCP connection and an encrypted SSL connection for transferring data from a forwarder to an indexer. The data forwarded to the indexer is also load balanced by default and even if one indexer is down due to network outage or maintenance purpose, that data can always be routed to another indexer instance in a very short time. Also, the forwarder caches the events locally before forwarding it, thus creating a temporary backup of that data.
License master in Splunk is responsible for making sure that the right amount of data gets indexed. Splunk license is based on the data volume that comes to the platform within a 24hr window and thus, it is important to make sure that the environment stays within the limits of the purchased volume.
Consider a scenario where you get 300 GB of data on day one, 500 GB of data the next day and 1 terabyte of data some other day and then it suddenly drops to 100 GB on some other day. Then, you should ideally have a 1 terabyte/day licensing model. The license master thus makes sure that the indexers within the Splunk deployment have sufficient capacity and are licensing the right amount of data.
If you exceed the data limit, then you will be shown a ‘license violation’ error. The license warning that is thrown up, will persist for 14 days. In a commercial license you can have 5 warnings within a 30 day rolling window before which your Indexer’s search results and reports stop triggering. In a free version however, it will show only 3 counts of warning.
This is a common question aimed at candidates appearing for the role of a Splunk Administrator. Alerts can be used when you want to be notified of an erroneous condition in your system. For example, send an email notification to the admin when there are more than three failed login attempts in a twenty-four hour period. Another example is when you want to run the same search query every day at a specific time to give a notification about the system status.
Different options that are available while setting up alerts are:
Data models are used for creating a structured hierarchical model of your data. It can be used when you have a large amount of unstructured data, and when you want to make use of that information without using complex search queries.
A few use cases of Data models are:
There will be a great deal of events coming to Splunk in a short time. Thus it is a little complicated task to search and filter data. But, thankfully there are commands like ‘search’, ‘where’, ‘sort’ and ‘rex’ that come to the rescue. That is why, filtering commands are also among the most commonly asked Splunk interview questions.
Search: The ‘search’ command is used to retrieve events from indexes or filter the results of a previous search command in the pipeline. You can retrieve events from your indexes using keywords, quoted phrases, wildcards, and key/value expressions. The ‘search’ command is implied at the beginning of any and every search operation.
Where: The ‘where’ command however uses ‘eval’ expressions to filter search results. While the ‘search’ command keeps only the results for which the evaluation was successful, the ‘where’ command is used to drill down further into those search results. For example, a ‘search’ can be used to find the total number of nodes that are active but it is the ‘where’ command which will return a matching condition of an active node which is running a particular application.
Sort: The ‘sort’ command is used to sort the results by specified fields. It can sort the results in a reverse order, ascending or descending order. Apart from that, the sort command also has the capability to limit the results while sorting. For example, you can execute commands which will return only the top 5 revenue generating products in your business.
Rex: The ‘rex’ command basically allows you to extract data or particular fields from your events. For example if you want to identify certain fields in an email id: firstname.lastname@example.org, the ‘rex’ command allows you to break down the results as abc being the user id, edureka.co being the domain name and edureka as the company name. You can use rex to breakdown, slice your events and parts of each of your event record the way you want.
There are about 5 fields that are default and they are barcoded with every event into Splunk. They are host, source, source type, index and timestamp.
You can extract fields from either event lists, sidebar or from the settings menu via the UI. The other way is to write your own regular expressions in props.conf configuration file.
You might not want to index all your events in Splunk instance. In that case, how will you exclude the entry of events to Splunk. An example of this is the debug messages in your application development cycle. You can exclude such debug messages by putting those events in the null queue. These null queues are put into transforms.conf at the forwarder level itself.
Splunk Apps are considered to be the entire collection of reports, dashboards, alerts, field extractions and lookups. Splunk Apps minus the visual components of a report or a dashboard are Splunk Add-ons. Lookups, field extractions, etc are examples of Splunk Add-on.
Sourcetype is a default field which is used to identify the data structure of an incoming event. Sourcetype determines how Splunk Enterprise formats the data during the indexing process. Source type can be set at the forwarder level for indexer extraction to identify different data formats. Because the source type controls how Splunk software formats incoming data, it is important that you assign the correct source type to your data. It is important that even the indexed version of the data (the event data) also looks the way you want, with appropriate timestamps and event breaks. This facilitates easier searching of data later.
This is a sure-shot question because your interviewer will judge this answer of yours to understand how well you know the concept. The Forwarder acts like a dumb agent which will collect the data from the source and forward it to the Indexer. The Indexer will store the data locally in a host machine or on cloud. The Search Head is then used for searching, analyzing, visualizing and performing various other functions on the data stored in the Indexer.
This is another frequently asked Splunk interview question which will test the candidate’s hands-on knowledge. In case of small deployments, most of the roles can be shared on the same machine which includes Indexer, Search Head and License Master. However, in case of larger deployments the preferred practice is to host each role on stand alone hosts. Details about roles that can be shared even in case of larger deployments are mentioned below:
In case the license master is unreachable, then it is just not possible to search the data. However, the data coming in to the Indexer will not be affected. The data will continue to flow into your Splunk deployment, the Indexers will continue to index the data as usual however, you will get a warning message on top your Search head or web UI saying that you have exceeded the indexing volume and you either need to reduce the amount of data coming in or you need to buy a higher capacity of license.
Questions regarding Search Factor and Replication Factor are most likely asked when you are interviewing for the role of a Splunk Architect. SF & RF are terminologies related to Clustering techniques (Search head clustering & Indexer clustering).
This is the kind of question which only somebody who has worked as a Splunk administrator can answer. The answer to the question is below.
As the name suggests, Search time field extraction refers to the fields extracted while performing searches whereas, fields extracted when the data comes to the indexer are referred to as Index time field extraction. You can set up the indexer time field extraction either at the forwarder level or at the indexer level.
Another difference is that Search time field extraction’s extracted fields are not part of the metadata, so they do not consume disk space. Whereas index time field extraction’s extracted fields are a part of metadata and hence consume disk space.
