Hi @deepakgaonkar,
if you need only operative system of each target server, you can use a search like this on Deployment Server:

| rest splunk_server=local /services/deployment/server/clients | table instanceName ip utsname

If instead you want more infos about your servers, as the operative system version, you have to use a Technology Add-On (TA) to extract this info from the target.
I'm speaking of TA_Windows (for Windows Servers) and TA_nix (for Linux servers).
You have to take these TAs, enable the stanza to check the operative system version and deploy them to all the targets.

Then you can run a search like this:
for Windows servers:

index=windows sourcetype=WinHostMon Type=OperatingSystem 
            | eval host=upper(host)
            | dedup host 
            | sort host 
            | table OS Version ServicePack BuildNumber SerialNumber InstallDate LastBootUpTime
            | eval 
               InstallDate=strftime(strptime(InstallDate,"%Y%m%d%H%M%S"),"%d/%m/%Y %H.%M.%S"),
               LastBootUpTime=strftime(strptime(LastBootUpTime,"%Y%m%d%H%M%S"),"%d/%m/%Y %H.%M.%S")

For Linux servers:

index=os sourcetype=Unix:Version
            | table os_name os_release os_version machine_architecture_name
            | rename os_name AS "Operative System" os_release AS Release os_version AS Version machine_architecture_name AS Architecture

Ciao.
Giuseppe

Install the Splunk Addon for Unix to your forwarders, and configure version.sh
https://splunkbase.splunk.com/app/833/

This input collects detailed version information from your host (amongst many other useful things if you wish), and as a bonus will add it to the Inventory Data model.
