I have installed Splunk_TA_nix add-on on my universal forwarder to send Linux logs, What is the difference between forwarding the logs through the add-on and forwarding logs through /etc/system/local/inputs.conf.?Will both does the same thing.?Will the Splunk_TA_nix add-on extract the fields from the linux logs (/var/log/messages,/var/log/maillog) which will be CIM compatible.?

Hi @sandeepduppalli,

there isn't any difference in inputs, the main difference is in management:

if you put all the inputs in dedicated TAs (e.g. TA_nix), you can distribute and update them using a Deployment Server, in other words, you have to modify apps in only one point.

If instead you put all the inputs in one big inputs.conf in $SPLUNK_HOME/etc/system/local, you cannot use Deployment Server and you have to manually deploy and update inputs.conf in all your servers.

So, if you have few servers (e.g. in a lab), you can do this manually, if you have many servers it isn't possible!

To better understand this way to deploy apps: it's a best practice to insert in a dedicated Technical-AddOn (called e.g. TA_Forwarder or TA_sendtoindexer) also the outputs.conf and deploymentclient.conf, that ofter are in $SPLUNK_HOME/etc/system/local, so you can manage them in a centralized way.

Ciao.

Hi @gcusello 

Thanks for that, one last thing, Does the Splunk_TA_nix add on extract the fields of the inputs provided to it which will be CIM compatible.? If this add-on doesn't do that Is there any other add-on which extract fields from my logs(eg: /var/log/*).

Hi @sandeepduppalli,

as you can see at https://splunkbase.splunk.com/app/833/ , this TA is compatible with CIM4.x.

Open it and see which inputs you have by default:

File and Directory Inputs:
/etc		
/home/*/.bash_history		
/Library/Logs		
/root/.bash_history		
/var/adm		
/var/log

Scripted Inputs:
bandwidth.sh			
cpu.sh			
df.sh			
hardware.sh			
interfaces.sh			
iostat.sh			
lastlog.sh			
lsof.sh			
netstat.sh			
nfsiostat.sh			
openPorts.sh			
openPortsEnhanced.sh			
package.sh			
passwd.sh			
protocol.sh			
ps.sh			
rlog.sh			
selinuxChecker.sh			
service.sh			
sshdChecker.sh			
time.sh			
top.sh			
update.sh			
uptime.sh			
usersWithLoginPrivs.sh			
version.sh			
vmstat.sh			
vsftpdChecker.sh
