Hi @rgadepal,
as you can see in the Splunk ideas, there's in analysis the possibility to add this feature to Deployment Server, but at the moment the esiest way is to use a tool (third-party management tool like Ansible, Puppet, etc.) otherwise you can use a script that installs one Universal Forwarder at a time, if you want to parallelize UFs installation you can run it more times:
Script
#!/bin/sh
# Script to remotely install Splunk forwarder
# to avoid to store readable password
read -s -p "Enter Splunk Admin Password: " PASSWORD
echo
# Configuration file
source /home/your_user/config.ini
# Command lists to execute in remote forwarder server
REMOTESCRIPT="
cd $DIRDEST
$WGETCMD
sudo tar -xzf $FWDTGZ
sudo chown -R splunk:splunk $DIRDEST/splunkforwarder
sudo -H -u splunk $DIRDEST/splunkforwarder/bin/splunk start --accept-license --answer-yes --auto-ports --no-prompt
sudo $DIRDEST/splunkforwarder/bin/splunk edit user admin -password $PASSWORD -auth admin:changeme
sudo $DIRDEST/splunkforwarder/bin/splunk set deploy-poll \"$DEPLOYSERVER\" -auth admin:$PASSWORD
sudo $DIRDEST/splunkforwarder/bin/splunk enable boot-start -user splunk
sudo chown -R splunk:splunk $DIRDEST/splunkforwarder
sudo -H -u splunk $DIRDEST/splunkforwarder/bin/splunk restart
"
# Installation execution
echo "============================= FORWARDER REMOTE INSTALLER ============================="
echo
sleep 5
echo "Reading host logins from $TARGETSFILE"
echo
echo "Start Forwarder remote installation to:"
# hosts cycle
for DEST in `cat "$TARGETSFILE"`; do
if [ -z "$DEST" ]; then
continue;
fi
echo
echo "- $DEST"
ssh "$DEST" "$REMOTESCRIPT"
done
Config.ini
TARGETSFILE="/home/my_user/targets.ini"
DIRDEST="/opt"
WGETCMD="sudo wget -O splunkforwarder-your_version.tgz 'your_link"
FWDTGZ="/opt/splunkforwarder-your_version.tgz"
DEPLOYSERVER="your_Deployment_Server:8089"
Adapt the script to your needs.
In addition you could insert your host list in another file and read them from it.
Another hint is to copy in $SPLUNK_HOME/etc/apps a Technical Add-on in which there are two files: outputs.conf and deploymentclient.conf, in this way your Forwarders will connect directly to you Deployment Server and you can manage them
Ciao.
