Forward Data to Splunk Server

[Kai191]

Hi, I am new to Splunk and I would like to ask how to send data over from the client PC over to my Splunk server, which is in a VM workStation. (I know it had to use a fowarder, but I just could't get my data to send over, and config, the receiver to using port 9997.(I am capturing tcp packet))

[templier]

Example my inputs.conf from one of computer:

[default]
host = hostname

[monitor:///var/log/Snort_log]
disabled = false
sourcetype = snort_alert_full
index = snort

For test you can specify the directory with the syslogs and change sourcetype.


[monitor:///var/log/syslog.log]
disabled = false
sourcetype = syslog
index = main

And restart.

In _internal index you can see information about the connection forwarder to server.
In search line enter index="_internal"

how can i understand that is data is sent to the indexer from forwarder ? And indexer is really receiving the data.

Hi,

I am new to splunk. I used splunk forwarder to forward data to splunk indexer(receiver). Can you please suggest how to check on the receiver that the data sent from the forwarder is indexed.

Thanks,
Neel

In output.conf the setting is already done. I set previously. Please send the input.conf so that I can configure it.
I already added a path to splunkforwarder to monitor using the following command:

./splunk add monitor

how can i understand that is data is sent to the indexer. And indexer is really receiving the data.

[tcpout]
defaultGroup = default-autolb-group

[tcpout:default-autolb-group]
server = Server (indexer) ip:9997

[tcpout-server://Server (indexer):9997]

In inputs.conf add directory where you need to take logs.

I use splunk for colleck snort logs from ubuntu and windows. If you want i can send you me config file as an example.

Ok, Fedora on server (indexer) and fedora on machines where it will be necessary to collect data?

First thing to do to set the port to transfer data on the server (indexer) go Settings-Forwarding and receiving-Receive data-Add new and add 9997 porn (
or other free open port).
After that go to the machine where you installed splunk forwarder (/opt/splunkforwarder/etc/system/) and edit outputs.conf

i am using Fedora(linux).

Hello!

What operating system are you using?

[ddarmand]

Can you use the universal forwarder ?

Hey Kai191, with regard to the logs, if you are on the forwarder and you go to the following location, you will be able to see the log files:
/opt/splunkforwarder/var/log/splunk

Have a look through the splunkd logs...this should let you know if there are any connection issues with the forwarder connecting to the indexer

That is likely the same thing.

I only installed the splunk forwarder

Hi Vince,
1) I am unable to telnet.
2) I had set the file in the required path.
3) I used netstat -a it show 0.0.0.0 9997 is listening (is it correct?)
4) how do i see the splunkd or metric log?
I am just a beginner in splunk, so your patience is much appreciated

Thanks in advance for the help.

Hey Kai191,
I think Ayn is trying to get some further information on your set up and what troubleshooting you have performed so far. Can you please do the following and provide the answers:
1. can you telnet from the forwarder to indexer on port 9997, eg; telnet 9997
2. Have you set up the /opt/splunkforwarder/etc/system/local/outputs.conf and print out the info
3. Can you please run a netstat to see if ports are listening on the index host, eg; netstat -tnap | grep 9997
4. Are you seeing any errors in the splunkd or metrics logs on the forwarder.

Regards Vince

I am currently stuck at unable to send data over to my splunk server.

Some more information could certainly help - where are you currently getting stuck?
