Splunk

Hi all,

I am trying to setup splunk to monitor all the remote hosts on a Splunk server. Without any issues, i have set up the Splunk server. I have installed the Universal forwader on Remote host and provides inputs.conf and outputs.conf as below. But some how these logs are not getting routed to Splunk server. I am stuck here though i change some configuration according to the Splunk documentation, i have not got the output. can anyone suggest me.

inputs.conf
[default]
[monitor:///var/log/messages]
disabled = 0
source type = messages_log
index = system_log

outputs.conf
[tcpout:default-autolb-group]
disabled = false
server = 192.189.11.34:9997

To rule out firewall; from client, if you try to telnet to that splunk server and it's listening port, does it connect?

oh yes, Telnet to the port is not listening

Trying ...
telnet: Unable to connect to remote host: Connection refused
 WARN  TcpOutputProc - The TCP output processor has paused the data flow. Forwarding to output group default-autolb-group has been blocked for 514002 seconds. This will probably stall the data flow towards indexing and other network outputs. Review the receiving system's health in the Splunk Monitoring Console. It is probably not accepting data.

But i have configured the receiving port for splunk dashboard, also I opend the port 9997 on the Remote host. But its unable to connect

Let's simplify, the host running splunk, can you configure to send its logs to splunk?

Try this on your Splunk servers, if you don't get the result line then you've not configured Splunk correctly or haven't restarted it.

# netstat -lnp | grep 9997
tcp        0      0 0.0.0.0:9997            0.0.0.0:*               LISTEN      30215/splunkd

Oh, and rather than relying on telnet you can try this to find out if the port is open/listening:

(echo >/dev/tcp/192.189.11.34/9997) &>/dev/null && echo "open" || echo "closed"

so its says port is closed

i used below command to open the port, but it still says the port closed. any suggestions?

iptables -A INPUT -p tcp --dport 9997 --jump ACCEPT
iptables-save
