How to send journal logs to splunk ?

How do i send journal logs to splunk??

journalctl -u servicename

Here journal logs are raw logs. Will splunk read raw logs ?

Configuration setup on my bos-server1
root@bos-server1#/opt/splunkforwarder/etc/apps/linux_auth/default# cat inputs.conf
[monitor:///var/log/auth*.log]
sourcetype = linux_authlog
index = linux_log
disabled = false

[monitor:///var/log/syslog]
sourcetype = linux_syslog
index = linux_log
disabled = false

Below journal logs location:

root@bos-server1:/run/log/journal/112824edd9f56398bab569035733662e# pwd
/run/log/journal/112824edd9f56398bab569035733662e

Hello @meenakande ,

depending on OS, the journal logs usually duplicated in various /var/log/*log so just by monitoring them with monitor stanza as you mentioned should work in most cases.
The /run/log/journal/* files are binary files and cannot be consumed by splunk.

If you run splunk forwarder as not root user then you need to modifiy file/folder permissions to allow splunk read logs in /var/log directory.

What is the problem you are currently have?

Run these commands on the linux splunk forwarder:

ps aux|grep -i splunk

ls -ld /var/log

ls -l /var/log/*log

When you restart Splunk (or the forwarder if that is what you are using) after changing the inputs.conf file, data should be sent to Splunk. What do you get when you search index=linux_log?
