Splunk universal forwarder msi switches7/27/2023 A single team should be responsible for Splunk instead of having this split across multiple departments, divisions, or entities. We strongly recommend using Splunk_TA_Windows.įor very in depth logging on critical systems, consider using the Splunk addon for Microsoft sysmon in addition to Splunk_TA_Windows. The Splunk Universal Forwarder doesn’t have these limitations and can be used to reliably and efficiently collection Windows events from a large distributed Enterprise. Many Windows event collection tools have various limitations such as the truncation of events at 512 or 1024 bytes. Use a consistent naming scheme on the Splunk Search Heads, Indexers to ensure accuracy and reduce troubleshooting time.Ĭarefully plan the deployment of Windows event collection (Event logs and Performance data) to ensure success. All of this makes your Splunk deployment more extensible, provides better access control options, and allows for fine-grained troubleshooting and analysis. Such as: management, log collection, web UI/search head and use separate IPs for different major sourcetypes. Use separate IP addresses whenever possible. This will improve the search head’s speed in accessing the events. Try to keep search heads as close to indexers as possible. ![]() These events can be collected with a Splunk Universal Forwarder, and then sent to indexers which may be a central location. ![]() Try to collect events as close (in terms of geography and network location) as possible. See this great blog-post on Sourcetype naming. If the events are generated by the same device and are in the same format, they should most likely be one sourcetype. Use sourcetypes to group data by their similarity. Indexes and sourcetypes assist in data management. These two things will be difficult to change later. For large deployments, a stand-alone system is important This system is typically co-located with the Deployment server. This system typically acts as the License Master. For large deployments, a stand-alone system is important. This system can be collocated with other Splunk services, or stand-alone. This separate system will distribute any search request across all configured search-peers improve search performance.Ī separate search head is shown here to support Splunk’s Enterprise Security (ES) applicationĭeployment Server. This strategy reduces search time and provides some redundancy of data-ingest and availability should a single server fail Multiple clustered search-peers (indexers) improves performance both during data-ingest and search. This architecture has several key components such as:Īn indexer tier with indexer clustering. Largely, most of this applies to most environments we see. ![]() A successful implementation is one that is efficient, scalable, follows information security best-practice, and is, most importantly, useful.Īlthough everything here is valuable, some of it does not apply for very small or specific implementations of Splunk. Many of these items come up time and time again during engagements and consideration of these items will result in a more successful implementation. ![]() The universal forwarder automatically starts.įrom Windows Control Panel, confirm that the SplunkForwarder service runs.The recommendations in this document were compiled by Aplura‘s staff over their many years of Splunk administration and professional services engagements. The installer runs and displays the Installation Completed dialog box. In the Receiving Indexer pane, leave it empty for the receiving indexer that you want the universal forwarder to send data to and click Next.Ĭlick Install to proceed with the installation. In the Deployment Server pane, enter management port 8089 for the deployment server that you want the universal forwarder to connect to and click Next. Do at least one of the following two steps:.Check Generate random password to let Splunk generate a password for you. (Optional) Select one or more Windows inputs from the list and click Next.Ĭreate a username and password for your Universal Forwarder administrator account. See "Install as a low-privilege user" for information about securing your system when installing as a local user. Do not specify any parameters.Īs a best practice, run the Universal Forwarder as the Local System user and click Next. On the Certificate Information page, click Next as a best practice. (Optional) In the Destination Folder dialog box, click Change to specify a different installation directory. To change any of the default installation settings, click the "Customize Options" button.Select the Check this box to accept the License Agreement check box and the check box for either Splunk Enterprise or Splunk Cloud. The first screen of the installer should pop-up. Install a Windows universal forwarder from an installerĭouble-click the MSI file to start the installation.
