States "There are currently no forwarders configured as deployment clients to this instance." Receive data: Forwarding and receiving: Receive data But the Splunk Web interface stubbornly insists that "There are currently no forwarders configured as deployment clients to this instance." I have a single-instance Splunk Enterprise environment, with a Universal Forwarder on another machine. Using Deployment Server, you can configure these classes, configure the app once centrally, and push the appropriate app/configuration to the right systems. So you may want to have your production servers class have the unix app configured to execute those scripts listed in ~local/inputs at the default values, but maybe your QA servers only need a few of the full stack, and at longer polling intervals. This can be used to define server classes and push out specific apps and configurations to those classes. Note that Splunk also has a centralized configuration management server called Deployment Server. Step 10 (Optional): Configure File System Change Monitoring (for configuration files): The ~local/nf shows what has been enabled – if you want to change polling intervals or disable certain scripts, make the changes in ~local/nf. path shows what the app can do, but everything is disabled. Look at nf in /opt/splunkforwarder/etc/apps/unix/local/ and /opt/splunkforwarder/etc/apps/unix/default/ Step 9 (Optional): Customize UNIX app configuration on forwarders: Note: The data collected by the unix app is by default placed into a separate index called ‘os’ so it will not be searchable within splunk unless you either go through the UNIX app, or include the following in your search query: “index=os” or “index=os OR index=main” (don’t paste doublequotes) Restart the Splunk forwarder (/opt/splunkforwarder/bin/splunk restart) If done correctly, you will have the directory "/opt/splunkforwarder/etc/apps/Splunk_TA_nix" and inside it will be a few directories along with a README & license files. Go to and find the "Splunk Add-on for Unix and Linux" (Note you want the ADD-ON, not the App - there is a difference!).Ĭopy the contents of the Add-On zip file to the Universal Forwarder, in: /opt/splunkforwarder/etc/apps/. Once you’ve configured the UNIX app on the server, you'll want to install the related Add-on: "Splunk Add-on for Unix and Linux" on the Universal Forwarder. Restart Splunk if prompted, Open UNIX app -> Configure On the Splunk Server, go to Apps -> Manage Apps -> Find more Apps Online -> Search for ‘Splunk App for Unix and Linux’ -> Install the "Splunk App for Unix and Linux' Step 8 (Optional): Install and Configure UNIX app on Indexer and *nix forwarders: If you have application logs in /var/log/*/ Note: System logs in /var/log/ are covered in the configuration part of Step 7. This will create a file: nf in /opt/splunkforwarder/etc/apps/search/local/ - here is some documentation on nf: Where /path/to/app/logs/ is the path to application logs on the host that you want to bring into Splunk, and %app% is the name you want to associate with that type of data opt/splunkforwarder/bin/splunk add monitor /path/to/app/logs/ -index main -sourcetype %app% opt/splunkforwarder/bin/splunk list forward-server Manager -> sending and receiving -> configure receiving -> new) (where hostname.domain is the fully qualified address or IP of the index server (like ), and 9997 is the receiving port you create on the Indexer: opt/splunkforwarder/bin/splunk add forward-server hostname.domain:9997 Step 5: Configure Forwarder connection to Index Server: Where 9997 (default) is the receiving port for Splunk Forwarder connections opt/splunk/bin/splunk enable listen 9997 Manager -> sending and receiving -> configure receiving -> new Step 4: Enable Receiving input on the Index ServerĬonfigure the Splunk Index Server to receive data, either in the manager: (start splunk: /opt/splunkforwarder/splunk start) opt/splunkforwarder/bin/splunk enable boot-start Step 1: Download Splunk Universal Forwarder: Steps for Installing/Configuring Linux forwarders: Note: the CLI may ask you to authenticate – it’s asking for the LOCAL credentials, so if you haven’t changed the admin password on the forwarder, you should use admin/changeme
