Install and Configure Splunk Universal Forwarder
You may have chosen an architecture option where uberAgent interacts with Splunk through Splunk s Universal Forwarder which can be viewed as a generic agent. In that case you need to install Universal Forwarder on every machine you want to monitor with uberAgent.
The following description shows you how to install and configure Universal Forwarder for uberAgent. In this example, the Splunk server s FQDN is srv1.hk.test .
Launch the Universal Forwarder MSI file. Accept the license agreement and click Next .
If you have Splunk Enterprise you can use Splunk s Deployment Server functionality to deploy apps. In that case specify the Splunk server name. You can leave the port empty to use the default. If you have Splunk Free leave both fields empty.
Specify the name of your Splunk Indexer. In this simple walkthrough our Splunk server also acts as indexer. Again, the port is left at the default value:
Receive uberAgent Data via TCP Port
If you want Universal Forwarder to handle all Splunk communications you can configure uberAgent to pass all output to the Universal Forwarder on the same machine. To do that open a TCP port uberAgent can send data to by adding the following to $SPLUNK_HOME\etc\system\local\inputs.conf on your Universal Forwarders:
Note:$SPLUNK_HOME refers to the base directory of the Splunk (Forwarder) installation, typically C:\Program Files\SplunkUniversalForwarder .
If you are deploying the uberAgent_endpoint app port 19500 is opened for you automatically (details here ).
Complement uberAgent s Metrics
Universal Forwarder includes the Splunk Add-on for Windows which can be used to collect additional data uberAgent deliberately does not provide because it is available via Universal Forwarder. These additional data sources include log files, event logs, file system and registry changes, printer and print job data, Active Directory objects and changes.
Disable Universal Forwarder Eventlog Data Collection
A default installation of Universal Forwarder sends all data from the Windows Application, Security and System event logs to Splunk. If you do not need that edit $SPLUNK_HOME\etc\apps\Splunk_TA_windows\local\inputs.conf so that all stanzas are disabled as in the following example:
Unattended (Silent) Installation
You can find all the information required for automating the deployment of Universal Forwarder here .
Preparation for Imaging / Citrix PVS
If you intend to copy the installation via an imaging method or Citrix PVS you need to remove instance-specific information such as server name and GUID from the Universal Forwarder installation. To do that follow these steps right before capturing the image:
- Stop the service SplunkForwarder (but leave the start type at automatic )
- Open an administrative command prompt
- Run the command: C:\Program Files\SplunkUniversalForwarder\bin\splunk clone-prep-clear-config
- Prepare the machine for cloning as necessary, but do not reboot
