It describes the nodes of a single-site cluster and how they work together. Download manual as PDF Version ... For information on how cluster architecture differs for SmartStore indexes, ... Splunk Enterprise stores indexed data in buckets, which are directories containing files of data. For a deeper dive into cluster architecture, read the chapter How indexer clusters work. By creating a server class, you are telling the deployment server that a specific set of clients should receive configuration updates in the form of a specific set of apps. There are, however, a few areas of significant difference. Also this will be standalone architecture to collect, parse and extract events rather a distributed architecture where multiple components are required to collect, parse, extract and display event in Splunk. The bucket copies are either searchable or non-searchable. This diagram provides a conceptual overview of the relationship between a deployment server and its set of deployment clients and server classes: In this example, each deployment client is a Splunk Enterprise forwarder that belongs to two server classes, one for its OS and the other for its geographical location. This diagram shows the movement of data into peers, both from forwarders and from other peers: You can set up your cluster so that all the peer nodes ingest external data. We also use these cookies to improve our products and services, support our marketing campaigns, and advertise to you on our website and other websites. The cluster will contain three complete copies of the peer's data. Splunk Architecture Overview (e-learning) This one-hour course provides an overview of the Splunk architecture. To ensure rapid recovery from one downed node, the search factor must be set to at least 2. This diagram represents a very simplified version of peer replication, where all data is coming into the system through a single peer. planning a Splunk® deployment, can achieve orders of magnitude, up to 33 times better indexing and ingest performance and orders of magnitude, up to 100’s of times, better search performance using Apeiron CaptiveSAN® Splunk Appliances when compared to Splunk® reference architecture that assumes traditional The number of peer nodes you deploy is dependent on two factors: the cluster replication factor and the indexing load. The manager node rebalances primaries across the set of peers whenever a peer joins or rejoins the cluster, in an attempt to improve distribution of the search load. For information on how indexing works in a multisite cluster, read Multisite indexing. When a search across data sources is constructed, the user can save, run, and send the search results and graphical reports to others in PDF format on a scheduled basis. 8.1.0, Was this documentation topic helpful? A complete cluster also has search factor number of searchable copies of each bucket. You are not required to use forwarders to get data into a cluster, but, for most purposes, you will want to. This topic introduces indexer cluster architecture. Search heads, however, can search across multiple clusters. We use our own and third-party cookies to provide you with a great online experience. This documentation applies to the following versions of Splunk® Enterprise: Primary copies of those 20 buckets could be spread across all three peers, with 10 primaries on the first peer, six on the second, and four on the third. Example 2: Distributed Single-Site Cluster Characteristics High Availability for data ingestion and search peers via configurable data replication Horizontally scalable indexing to multi-TB/day Total number of unique buckets in indexer cluster limited to 5MM as of Kimono (6.6), 15MM total buckets No DR capability in case of data center outage Peer nodes perform the indexing function for the cluster. Please select The search factor determines the number of peers that index the data. If so, what is the retention period and requirement for doing so? A remotely configured Splunk Enterprise instance. LOGO Splunk 2. Please select You use a deployment server to distribute content and configurations (collectively called deployment apps) to deployment clients, grouped into server classes. Architecting Splunk Enterprise Deployments Generated for Rafal Kondracki Multisite cluster architecture is similar to single-site cluster architecture. That allows the manager node to immediately replace primaries on the downed node with existing searchable copies on other nodes. It deploys configuration updates to other instances. It can be availed from Splunk itself or through the AWS cloud platform. LOGO Splunk ? For more information, read Multisite searching. Indexing and search topology 2. If there are less peer nodes remaining than the number specified by the replication factor, the cluster will not be able to replace the 20 missing copies. An index typically consists of many buckets. In this tutorial I have discussed about basic Architecture of Splunk. It coordinates the replicating activities of the peer nodes and tells the search head where to find data. While this time-intensive process is occurring, the cluster has an incomplete set of primary buckets. For example, if you have a three-peer cluster configured with a replication factor of 3, each peer can be ingesting and indexing external data while also storing copies of replicated data streamed to it by the other peers. Manager nodes, peer nodes, and search heads are all specialized Splunk Enterprise instances. in Deployment Architecture, topic Re: Deployment server in Deployment Architecture, "Deploy configurations to several forwarders", Learn more (including how to update your settings) here ». Look at the above image to understand the end to end working of Splunk.

For information on how search works with SmartStore indexes, see How search works in SmartStore. See Multisite replication and search factors. I did not like the topic organization This book is designed to reach beyond the typical techie Please try to keep this discussion focused on the content covered in this documentation topic. Scaling your Splunk Architecture. If you need assistance implementing a Splunk Validated Architecture, contact Splunk Professional Services. A search head cluster consists of a group of search heads that share configurations, job scheduling, and search artifacts. Search head clustering architecture. Splunk Light is a free version. The original bucket and its copies on other peer nodes have identical sets of rawdata. Splunk’s default SSL posture 4 For example, assume a cluster of three peers is maintaining 20 buckets that need to be searched to fulfill a particular search request coming from the search head. A peer node can be indexing external data while simultaneously storing, and potentially indexing, copies of replicated data sent to it from other peers. The number of copies is called the cluster's replication factor. Forwarders function the same as in any Splunk Enterprise deployment. Splunk Architecture 1. Enter your email address, and someone from the documentation team will respond to you: Please provide your comments here. In most three-peer clusters, all three peers would be receiving external data from a forwarder, as well as replicated data from other peers. in Deployment Architecture, topic Does Splunk support two search head clusters with one indexer cluster? Here is a diagram of a simple single-site cluster, with a few peers and some forwarders sending data to them: Some of what is happening in this diagram might not make sense yet; read on. 9 Splunk Architecture 10. A deployment client can belong to multiple server classes. I schedule report and recevie mail from the pdf report server. Figure 1. consider posting a question to Splunkbase Answers. Problems eventually will arise, however, particularly if one of the peers goes down. 6.3.0, 6.3.1, 6.3.2, 6.3.3, 6.3.4, 6.3.5, 6.3.6, 6.3.7, 6.3.8, 6.3.9, 6.3.10, 6.3.11, 6.3.12, 6.3.13, 6.3.14, 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4, 6.4.5, 6.4.6, 6.4.7, 6.4.8, 6.4.9, 6.4.10, 6.4.11, 6.5.0, 6.5.1, 6.5.2, 6.5.3, 6.5.4, 6.5.5, 6.5.6, 6.5.7, 6.5.8, 6.5.9, 6.5.10, 6.6.0, 6.6.1, 6.6.2, 6.6.3, 6.6.4, 6.6.5, 6.6.6, 6.6.7, 6.6.8, 6.6.9, 6.6.10, 6.6.11, 6.6.12, 7.0.0, 7.0.1, 7.0.2, 7.0.3, 7.0.4, 7.0.5, 7.0.6, 7.0.7, 7.0.8, 7.0.9, 7.0.10, 7.0.11, 7.0.13, 7.1.0, 7.1.1, 7.1.2, 7.1.3, 7.1.4, 7.1.5, 7.1.6, 7.1.7, 7.1.8, 7.1.9, 7.1.10, 7.2.0, 7.2.1, 7.2.2, 7.2.3, 7.2.4, 7.2.5, 7.2.6, 7.2.7, 7.2.8, 7.2.9, 7.2.10, 7.3.0, 7.3.1, 7.3.2, 7.3.3, 7.3.4, 7.3.5, 7.3.6, 7.3.7, 7.3.8, 8.0.0, 8.0.1, 8.0.2, 8.0.3, 8.0.4, 8.0.5, 8.0.6, 8.0.7, 8.1.0, Was this documentation topic helpful? There is no way to recover from peer loss without the manager node, and the search head will then be searching across an incomplete set of data. In addition, a cluster deployment usually employs forwarders to ingest and forward data to the peers. Splunk is often used by system administrators, network administrators, and security gurus, but its use is not restricted to these audiences. in Deployment Architecture. If you're looking for information about third-party components used in Splunk Enterprise, see the credits section in the Release notes. You need a good grasp of buckets to understand cluster architecture. About deployment server and forwarder management, Use forwarder management to define server classes, Use forwarder management to manage clients, Use serverclass.conf to define server classes, Extended example: Deploy configurations to several forwarders. For example, the manager node cannot reside on the same instance or machine as a peer node or a search head. They consume data from external sources and then forward that data to indexers, which, in clusters, are the peer nodes. The activity to replace the searchable copies from the downed node will still occur, but in the meantime searches can continue uninterrupted across all the cluster's data. The images shows a few remote Forwarders that send the data to the Indexers. Any full Splunk Enterprise instance - even one indexing data locally - can act as a deployment server.

Searches can then occur across the full set of data. A unit of content deployed to the members of one or more server classes. This is because only with forwarders can you enable indexer acknowledgment, which ensures that incoming data gets reliably indexed. For detailed information on manager node failure, read the topic What happens when a manager node goes down. Then read the topic Buckets and indexer clusters. For example, if you have a replication factor of 3 (which means you intend to store three copies of your data), you need at least three peers. Splunk Light . This is the most common scenario. If a manager node goes down, peer nodes can continue to index and replicate data, and the search head can continue to search across the data, for some period of time. Ask a question or make a suggestion. No, Please specify the reason Also refers to the overall configuration update facility comprising deployment server, clients, and apps.

Clustered indexing functions like non-clustered indexing, except that the cluster stores multiple copies of the data. For example, if you have a cluster of five peer nodes, with a replication factor of 3, the cluster will still be able to maintain a full set of primary copies if one or two peers go down but not if a third peer goes down. Some cookies may continue to collect information after you have left our website. To ensure that exactly one copy of each bucket participates in a search, one searchable copy of each bucket in the cluster is designated as primary. This tool can be used for data visualization, report generation, data analysis, etc. 1.4 Overview of the Splunk Phantom Validated Architectures Selection Process The Splunk Phantom Validated Architectures selection process will help you identify the simplest and most streamlined architecture that meets all of your organization's needs. Here is a high-level representation of a cluster with three peers and a replication factor of 3: In this diagram, one peer is receiving data from a forwarder, which it processes and then streams to two other peers. For information on multisite cluster architecture and how it differs from single-site cluster architecture, read the topic Multisite indexer cluster architecture. If a peer node goes down, the manager node coordinates attempts to reproduce the peer's buckets on other peers. Searchable copies also contain the index files. Based on the feedback on the data, the IT team will be able to take the necessary steps to improve their overall efficiency. © 2020 Splunk Inc. All rights reserved. Log in now. You must be logged into splunk.com in order to post comments. A cluster has exactly one manager node. To understand how a cluster functions, you need to be familiar with a few concepts: This section provides a brief introduction to these concepts. See Rebalance the indexer cluster primary buckets. Splunk Enterprise architecture and processes. Closing this box indicates that you accept our Cookie Policy. Also, there are various processes in place to ensure that a search occurs over one and only one copy of each bucket.
