This configuration allows you to assign a user to a group in AD then map this group to a role in Splunk. This means any DLL referenced by the “Logging Host” MUST be available on the “EVT(X) File Parsing Host” in order to interpret the logs. Ensure you have a way to consistently and accurately manage configurations across the enterprise, such as with the Splunk deployment server, Information: Topologies for Deployment Server, Information: Configure Deployment Clients. Test new inputs. Additionally, much of the deployment of Splunk requires an intimate understanding of its intended use and therefore it is recommended that the team who will be the major user of Splunk should also manage its deployment. Splunk is a fantastic tool for individuals or organizations that are into Big data analysis. Please try to keep this discussion focused on the content covered in this documentation topic. In situations where remote offices are bandwidth limited or may have un-reliable network connections, consider using an Intermediate Universal Forwarder. Methodically plan storage needs for a new deployment, prior to implementation. Deployment Server: Best practices for scaling coltwanger. Solid state drives provide the largest speedups in the “needle in a hay stack” use case. If you have a more general question about Splunk functionality or are experiencing a difficulty with Splunk, To address the problem, limit the indexing of these event codes by blocking some of the events which contain them (the app uses the events for Group Policy monitoring but no other purpose.). Dimitri McKay has held a list of positions in the security space through his 20+ years of working with Fortune 500 companies in and around security best practices, architecture and design. This should be considered the minimum. Splunk Best Practices The recommendations in this document were compiled by Aplura's staff over there more than 5-years of Splunk administration and professional services engagements. Data retention. Instead, configure a Splunk Forwarder to access Windows Event Manager directly to ingest Windows Events. Enterprise Security has many useful dashboards for various protocols. This can greatly impact license volume and potentially cause violations. The syslog-ng developers have a blog post where they discuss possible volumes with the 2.0 OSE: This means they are processing 44000*150=6600000 bytes per second, Multiply 6600000*8 to get bandwidth: 52,800,000, So syslog-ng optimally configured (by its developer) can use about half of the 100/mbs Ethernet connection without dropping packets. These numbers should be considered the absolute maximum an Indexer can do under ideal circumstances. Information: Splunk has the ability to use WMI to monitor Eventlogs remotely. By the end of this course you will gain enough knowledge to complete “Splunk power user certification” How to estimate a Splunk architecture servers. Splunk allows you to generate graphs, alerts, and dashboards. Finally, you should understand your data sources and either their load/volume or the complexity required to collect data from them. Look at the image below to get a consolidated view of the various components involved in the process and their functionalities. Use a consistent naming scheme on the Splunk Search Heads, Indexers to ensure accuracy and reduce troubleshooting time. This may be a result of either inconsistent AD details or missing DLLs on the “Log Parsing Host”, Splunk on Windows can natively ingest EVT(X) files, Adjust VM Swap. Carefully and consistently use Splunk’s listening ports, which bind to specific back-end processes. (On Windows Server 2003 and Server 2003 R2, the event code is 566). We detail configuration of the hardware and software components involved, provide various testing results, and offer implementation and best practices guidance. If you must do this manually, read and understand the docs and how the bucket structure works, and you can take a look at this answers post on the subject. Both the slides and a recording are available. Generally speaking indexers do particularly well with 16+ GB of memory, meanwhile other components might require less. New Index. The information provided in Splunk Lantern is intended for informational and educational purposes only. Memory Spec. Consider this before dropping any data that could be useful in the future. This nine-hour course focuses on large enterprise deployments. This is granular Role Based Access Controls (RBAC). Solid state drives can result in a massive speedup in very specific use cases. You should also install the Splunk Add-on for Windows (Splunk_TA_Windows) onto the host to get all other Windows data for the host into the Splunk App for Windows Infrastructure. When the amount of incoming data exceeds this buffer, packets are dropped. This documentation applies to the following versions of Splunk® App for Windows Infrastructure: What are components of Splunk/Splunk architecture? This system typically acts as the License Master. Use RAID1+0 whenever possible for the Splunk datastore. Proxy servers listening directly on … WMI is very clunky, and generally should not be used due to network and system performance implications. TA_AD and TA_DNS are merged with TA-Windows version 6.0.0. (sample script below to put in cron.daily or weekly). ECS terminology Strip priority out of TCP inputs. Build your own Splunk apps and Consider the implications of parsing data directly on your Indexers or using Intermediate Heavy Forwarders. Traditional syslog technologies (syslogd, syslog-ng, rsyslogd) are simple and featureless compared to Splunk, but this is their advantage. Splunk has put together this Best Practices in the course of developing and using the Splunk App for Windows Infrastructure. Since these packages rarely change and require a small amount of resources, they are perfect for being the initial recipient of syslog data on the network. Students will learn steps and best practices for planning, data collection and sizing for a distributed deployment. All of this makes your Splunk deployment more extensible, provides better access control options, and allows for fine-grained troubleshooting and analysis. Occasionally review your inputs and ensure your data is accurate, time stamps are good, and there are no mistakes such as incorrect or duplicated events. This generally equates to a more successful implementation. This tool can be used for data visualization, report generation, data analysis, etc. Use separate IP addresses whenever possible. Closing this box indicates that you accept our Cookie Policy. It is a best-suited tool for root cause analysis. Divide by seconds per day 86400 to see an average of how much data could be pushed through the network on average: Multiply the above by 8 to get bits per bytes. Consider taking a Splunk EDU class. These files are nothing like normal log files and therefore present some challenges to any attempt to reconstitute them back into usable logs (Note: These issues have nothing to do with Splunk): They reference GUID/SIDs in lieu of system/user names. According to Splunk’s Documentation, a single indexer can accommodate up to about 300GB/day. This will improve the search head’s speed in accessing the events. Even when starting with one Indexer, starting with a master node to manage configurations on that indexer will ensure expanding to a multiple indexer setup is painless. Plan indexes and sourcetypes. Divide this by 400 (average bytes/message) and you get 15625 which is the total amount of messages we could possibly receive if optimally configured with tcp given the parameters. They reference DLL files that contain the pertinent information instead of placing it in the actual log. Even TCP syslog can be lost if the receiving host is unreachable. Splunk architecture At enterprise level it is rare to deal with a distributed deployment as opposed to a clustered deployment (and depending on the scale of your systems, the cluster and Disaster Recovery ( DR ) / High Availability ( HA ) components of Splunk will be pretty large). Many of these items come up time and time again during engagements and consideration of these items will result in a more successful implementation. Integrate Active Directory (AD) for authentication. This strategy reduces search time and provides some redundancy of data-ingest and availability should a single server fail. Inconsistent configurations leading to similar systems setting different metadata on the same type of logs. Modularize your programs for better reusability. Consider one Deployment Server instance for every 2000 polls per minute. Single team accountability. You must be logged into splunk.com in order to post comments. These two things will be difficult to change later. This is not intended to replace a scoping discussion with a Splunk Sales Engineer, but rather to assist a customer in preparation for a professional services engagement. You know you have a problem with too many files if the Splunk instance involved has something like this in its logs: File descriptor cache is full. The topic did not answer my question(s) This configuration provides rapid read and write disk I/O and low latency through the use of an all-flash Containing all of these knowledge-items helps with manageability of the data across an enterprise deployment. Any pivot or report generated by that data model will complete much quicker than it would without the acceleration, even if the data model represents a significantly large dataset. This tool is installed by default on 2008 AD systems, but would need to be installed manually as part of the RSAT package on other versions of Windows. In Splunk 6.2, there were a number of improvements to what will require a restart on the Indexers, and Indexer Clustering reduces this even further. Keep an Eye on Free Disk Space. Consider moving your Splunk database (SPLUNKDB) to its own volume to ensure clean separation of the binary/configuration structure and the data. To configure active directory monitoring on a specific domain controller, open, Create a new Active Directory monitoring stanza and set the. Ideally, have the files be application-specific (e.g. It is imperative that time stamps and timezone offsets be parsed and set correctly both for usability and efficiency purposes. Additionally, if leveraging existing groups there could be many other users in that group that you don’t want to have access to Splunk. The Splunk App for Windows Infrastructure does not need SID translation in the Security Event Log. Doing so can make troubleshooting problematic inputs more difficult. You don't need to collect a baseline - or dump - of your Active Directory schema to use with the Splunk App for Windows Infrastructure. Before activating Splunk Windows Forwarders configure custom indexes, Information: Monitor files and directories. Translation turns SIDs (the very long string that begins with S-1-5-21 and ends with a long jumble of numbers) into friendly account names. Imagine a device that generates messages that are 250-450 bytes with most being over 350. You must know the amount you expect to index/day. Other. If you are in a distributed deployment, with multiple Splunk search heads and forwarders, strongly consider using Deployment Server. No, Please specify the reason There are a few things to keep in mind though, specifically that you want to pass the following msiexec arguments: AGREETOLICENSE, INSTALLDIR (since many sites want to install to some drive besides c ), Below is an example content that you can put in a script/package-management and it is based on having a Splunk deployment server in place. To ensure that the Splunk App for Windows Infrastructure sees all data coming in from the hosts in your Exchange environment, confirm that those hosts have their clocks synchronized. A single team should be responsible for Splunk instead of having this split across multiple departments, divisions, or entities. You must make these changes inside the universal forwarders that you have installed on the AD domain controllers in your environment. For large deployments, a stand-alone system is important. 2.0.0, 2.0.1, Was this documentation topic helpful? Splunk hardware planning: Determine what components you need. More best practices. This article explains how splunk data models and datasets work, how to define a data model using the Splunk editor, and important best practices for efficient data model design. In very specific use-cases, Heavy Forwarders can still provide value. Free Demo Session Timings: When deploying Indexers, strongly consider indexer clustering. DRP/BCP. The recommendations in this document were compiled by Aplura‘s staff over their many years of Splunk administration and professional services engagements. Deployment Architecture: Best practices Migrating from standalone indexers ... Options. Deployment Server. Perform integrity checks. Recommended Splunk Enterprise sizing: 150GB/day per Indexer. Data collection architecture components 3. This can be very tricky and you need to be careful since you could destroy and disable your data. Live handson experience with Splunk and supportive document for references . consider posting a question to Splunkbase Answers. Such as: management, log collection, web UI/search head and use separate IPs for different major sourcetypes. An indexer, when used in an ES deployment, can accommodate up to 100GB/day. This system can be collocated with other Splunk services, or stand-alone. GetWatchList is a free Splunk app on Splunkbase that allows users to manage lookup tables on the system without requiring shell or administrative access. Visual representation of the reference architecture Characteristics Written description of fitness-for purpose and limitations Tier-Specific Considerations and Best Practices What to look out for when building out a Splunkdeployment In Scope For Svas Components Of A SVA Manage Identities. Managing Splunk instances on these remote systems always has problems and leads to issues such as: Forwarders that have not had Splunk configured properly or locked down (e.g. The memory allocated to the UDP input buffer is distribution-specific. Configure a Disaster Recovery and Business Continuity Plan for your Splunk deployment. Splunk can work with either AMD or Intel architecture on x86 systems, but is typically run on Intel hardware. This hard-codes a download of the Splunk UF RPM at each invocation. Note that Splunk 6.6 and higher no longer provide the option to turn off autolb. 1. Beware not to go nullQueue-happy and drop too much. In our tests, many GUIDs and some DLL references didn’t convert in the event logs, leaving lots of useless events. (OU=unix_admins,OU=splunkgroups, OU=network_admins,OU=splunkgroups), then you can set the bindgroupDN to splunkgroups to minimize returned groups as well as users who have access to Splunk. Best practices guide. Review types of forwarders; Describe how to manage forwarder installation; Review configuration management for all Splunk components, using Splunk deployment tools; Provide best practices for a Splunk deployment; Module 7 - Integration . Enter your email address, and someone from the documentation team will respond to you: Please provide your comments here. Port commonly used to send events from a Splunk forwarder to a Splunk listener (indexer or another forwarder) using encryption. Splunk hardware planning: Know what the size/scope of your deployment is. NOTE: This can be any permissible port, 9998 is just an example. Information: Custom EventLogs on Splunk for Windows are discussed here. Consider backups for the $SPLUNK_HOME/etc on each standalone search head (non-pooled) and the cluster node to a remote drive on a frequent interval. Splunk doesn’t prescribe exactly what hardware you must purchase; however, you should read through the following documentation to better understand their minimum specs: CPU Spec. No Heavy Forwarders means you always know where your data is being parsed (the Indexer). Make better use of LVM partitioning by creating discrete logical volumes for each major portion of the system such as, Backup the deployment server, the $SPLUNK_HOME/etc/system/local/serverclass.conf and the /$SPLUNK_HOME/etc/deployment-apps directory to a remote drive is recommended to quickly build a new deployment server. Manage Assets Lists. If you cannot use this version of the universal forwarder, then this strategy does not apply to you. Change the admin password on forwarders. Be sure you know what you are changing and have tracked changes and the results appropriately to ensure it has the desired effect. Module 6 - Forwarder and Deployment Best Practices. The DS can be collocated with any other full Splunk instance; however, there are also some reasons why it might need to be stand-alone. All other brand names, product names, or trademarks belong to their respective owners. Generally speaking here are the standard ports, if they have not been altered: Splunk’s daemon port used for distributed search and deployment server. In the storage layer, VxRail leverages VMware vSAN technology to build vSAN on groups of local attached disks. In this file, modify the Security Event Log stanza. Drop incoming data with the nullQueue. Indexing and search topology 2. If you created a new base_ou (e.g. Moving away from Heavy Forwarders reduces the amount of systems to manage. Indexes and sourcetypes assist in data management. Systems generating events should have the proper time to ensure the events they create will be able to be correlated when analyzed. Data routing allows the Splunk administrator to selectively determine what incoming data gets ingested, what gets forwarded, and what gets dropped. Aditum’s Splunk Professional Services consultants can assist your team with best practices to optimize your Splunk deployment and get more from Splunk. Carefully configure your Splunk, 50000000000/86400 = 578703 (bytes/second), (50000000000/86400) * 8 = 4629624 (bits/second), On a version with UAC (User Access Controls) such as Visa, 2008 or Windows 7, you must be in an admin shell to install software, Very old (out of date) versions of Splunk throughout the enterprise, Use LVM to manage underlying file-system space. Also be aware that there are significant differences in the event format of SEP events between versions (most notably versions 11 and 12), which may result in failed extraction of fields if your TA or current extractions are expecting a different version. Memory is somewhat varied depending on what component you are talking about. cron) to move the previous day’s (or week perhaps) syslog directory out of the monitored directory-structure to an archive location. One or more separate search heads. Ensure a single instance of Splunk does not monitor more than a few hundred active files. Points to Remember. Before attempting any performance remedies, first try and determine what may be adversely affecting your deployment’s performance. For very in depth logging on critical systems, consider using the Splunk addon for Microsoft sysmon in addition to Splunk_TA_Windows. Our certified Splunk Architects and Splunk Consultants manage successful Splunk deployments, environment upgrades and scaling, dashboard, search, and report creation, and Splunk Health Checks. Answering these three questions will suffice for the average deployment, but not all deployments. Generally speaking, this scales linearly resulting in a situation where double the indexers will cut search time in half. Ensure all critical systems have consistent time configuration. firewall.log, router.log, maillog.log, etc.). It is advised that you call Splunk support or have PS help you. Expedite your reporting, and be empowered to present data in a meaningful way 3. RPM repo, Puppet, Satellite Server) to manage packages and configurations to forwarders and other related systems. We use our own and third-party cookies to provide you with a great online experience. If an unmentionable happened, you can copy this directory to a new Splunk instance to restore. Currently he’s a Principal Security Specialist for Splunk. Port commonly used to send events from a Splunk forwarder to a Splunk listener (indexer or another forwarder). Adjust ulimit. Be sure to understand what it is, and how it operates. Configure retention in indexes.conf to push older data to remote volumes such as NFS mount for data archive. Continue to manage your ES Asset List to always get the most value out of your deployment. For Symantec Endpoint Protection, you can put the SEP server in a configuration where it will write out temp files that a Splunk Universal Forwarder can read. This guide assumes a high level of technical knowledge for the devices and technologies described. It is almost always appropriate to use multiple indexes and not just main. In this tutorial I have discussed about basic Architecture of Splunk. Too many files. Enterprise Security’s search load can apply more memory pressure. Consider NTP use throughout the enterprise as well as frequent time audits of the most critical systems to ensure accuracy. Some of the benefits of using Splunk are: Offers enhanced GUI and real-time visibility in a dashboard ; It reduces troubleshooting and resolving time by offering instant results. On *nix hosts (if you use *nix hosts to host the Splunk App for Windows Infrastructure), use the. Data is often not considered security relevant at first, until there is a security incident related to the data. See the “Storage Hardware” section in this document for many notes regarding hardware. If the events are generated by the same device and are in the same format, they should most likely be one sourcetype. For indexers, the current sweet spot for servers has been 12-16 core machines (I.e. There are various ways to test your storage to benchmark your current values, but the mostly commonly used method is via the venerable tool bonnie++ found in the repository of every major Linux distribution. As of Splunk 5, it is also possible to use report acceleration. SEP Data import. This document covers the various best practices for Splunk on Pure Storage. Splunk can work with either AMD or Intel architecture on x86 systems, but is typically run on Intel hardware. This is a great resource for learning the search language. Splunk instances as virtual machines on a VMware vSphere 6.0 cluster following Splunk’s documented virtualization best practices. With that in mind, 24GB+ of memory on Indexers running ES is recommended. Use Splunk effectively to gather, analyze, and report on operational data throughout your environment 2. This white paper is a reference guide for configuring Splunk SmartStore with ECS and the recommended best practices. Ensure all (if possible) searches call saved searches or use other knowledge-items such as Macros or Eventtypes. This will include implementing a backup plan. Please select On a very busy server, this could happen frequently or in some cases continually. This page contains links to assorted topics on Splunk best practices. This is not necessary, but there are advantages in high-volume environments. Splunk should be run on 64 bit platforms. these instructions to Forward data to third party systems, network and system performance implications, Add Indexers when volume reaches 200GB/day/Indexer, Add indexers when volume reaches 80GB/day/Indexer. Splunk Architecture and SSL 4 Splunkweb (SSL to browsers) Splunk-to-splunk data transfer (forwarders to indexers) ... Best Practices Checklist Run Splunk forwarders as an unprivileged user Change forwarder admin passwords Enable strong SSL authentication between DS client and DS /splunk_hot) is mounted and relatively not in use (meaning stop Splunk if it is running). If you have a number of domain controllers, consider selecting one (or two to three for redundancy) and enabling the admon inputs only on those hosts. Master Node. Splunk recommends 800 IOPS (Input/Outputs Per Second) or better on your storage tier. Splunk’s reads the time stamp from incoming events, which it then associates to the event in the index and the underlying buckets. syslog-ng) on the network to receive the syslog feeds and configure the application to write the data out to files. If you need assistance implementing a Splunk Validated Architecture, contact Splunk Professional Services. Adding search load or app load to a distributed Splunk install will dramatically reduce the amount of indexed data per data that can be searched effectively. If msiexec is failing consider copying the MSI installer local and try it again. This includes the Splunk Classic architecture with Hot/Warm on Pure FlashArray, cold on Pure FlashArray over FC/iSCSI, or FlashBlade over NFS as well as Splunk SmartStore architecture with data on … A separate search head is shown here to support Splunk’s Enterprise Security (ES) application. There are many online guides (even on Splunk’s site) for how to run this tool; however, below is the gist: Ensure the target drive to be tested (e.g. These events can be collected with a Splunk Universal Forwarder, and then sent to indexers which may be a central location. The Splunk Enterprise event log monitor translates security identifiers (SIDs) by default for the Security Event Log. Largely, most of this applies to most environments we see.

While it is possible to configure SEP to send data via syslog, in some cases this data is incomplete, and unreliable. Solid state drives do not provide much performance in dense searches (high event counts). When doing an extreme amount of parse-time operations on data, such as large amounts of Index, Host, and Sourcetype renaming, a Heavy Forwarder may be used to reduce CPU load on Indexers. LOGO Splunk Server 9. and it is based on having a Splunk deployment server in place. Memory is somewhat varied depending on what component you are talking about. If you are processing 100GB/day of data volume for use with Enterprise Security, you will need approximately 340GB more space available across all of the indexers to allow for up to 1 year of data model retention and source retention. Architecture type. Consider not including a baseline for Active Directory data collection, Consider disabling the Active Directory monitoring input on all but a select group of domain controllers, Consider specifying a domain controller for Security Event Log Security ID (SID) translations, Consider limiting AD object access events to reduce impact on license usage. © 2020 Splunk Inc. All rights reserved. Since the EVT(X) files are a subset of the information they represent, a 99MB EVTX file converts to almost 500MB of indexed data. Use sourcetypes to group data by their similarity. The Splunk Reference Card PDF is also a great resource, and a laminated version can be purchased from the Splunk Schwag store. See Defaultfield and [Indexed Fields(https://docs.splunk.com/Documentation/Splunk/latest/Data/Configureindex-timefieldextraction)]. Try to keep search heads as close to indexers as possible. If an event is relayed through multiple syslog servers (for example the local syslog on a Linux system sending events to a remote syslog server), there may be two time stamps at the start of the event. Additionally, you should have a rough idea of how many Splunk users there will be, and what their intensity/usage will be. These lookups can be used in various ways but the most popular method is as watchlistsOS Configuration or Hardening. Design principles and best practices Splunk has put together this Best Practices in the course of developing and using the Splunk App for Windows Infrastructure.
