Hi @Ziadm,

let me understand: now you installed the UF on the DC but you have still problems, is this correct?

This is a new question, for the next time, please close the first question and the n opne a new one.

Anyway, some questions:

  • does you UF send logs to the indexer?, you can check on the indexer running a simple search like "index=_internal host=<DC_hostname>"
  • If yes, how are you taking DC logs, which add-on are you using?
  • if not, check the connection between UF and IDX using "telnet <ip_indexer> 9997"

Ciao.

Hi @Ziadm,

as I said, all the times I had a problem like your I opened a Case to Splunk Support.

Remember to create a Diag and attach it to the Case because this will be the first thing they'll ask you and they connot analyze you problem without it.

Ciao.

 i was able to solve the issue on my own apparently the firewall on the domain was blocking the connection to the deployment server/indexer
so i got this out of the way but now I'm facing another issue  after setting up everything I'm not receiving any events from the dc , i used the sysmon app because I only want to get the sysmon events for now  and I've enabled the inputs file as shown in the pic here

 I checked with netstat and the connection has been established but i got a couple of weird errors in splunk that i don't know what they mean and I'm still unable to get the events from the DC

Hi @Ziadm,

let me understand: at the end, does the Universal Forwarder run on your DC?

What do you mean with ended prematurely?

the error in the initial configuration isn't a problem, doesn't give any problem to your installation.

Anyway, I hint to open a case to Splunk Support for your problem.

Ciao.
