SPLUNK INPUTS.CONF ONLY HAS HOST NAME FULL

It is probably a good thing you made a mistake in how you wrote (looks like you missed 1. What exactly is the idea behind that transforms you have defined? The way you wrote this, it takes the last word of the event (since you do not define a SOURCE_KEY, it will work on _raw) and put that in the host field.

when the folder is showing an IP that probably indicates that host is not logging its name in the syslog header, which means the syslog hostname extraction fails and you keep the default host value of the forwarder.

thanks to syslog host extraction from the raw event, you still get the hostname for those machines that properly log their hostname.

as a result, all hosts get the default host value of the forwarder itself.

Is it possible to keep only one splunk-TCP port open with 2 differents behavior on 'connectionhost' dependi. But I would like it to be 'none' for some remote servers (Splunk UF sending to this splunktcp-ssl). I have to manually add the new IP to the clients list to get the other app to install, and after that i get events in the index with the desired hostname.

setting source=/var/log/syslogactually breaks the host_segment setting (not sure about this, but it would explain the rest of the Hi, I have a nf with splunktcp-ssl stanza.

When using sourcetype syslog, you get hostname extraction from the logs 'for free' based on below config in etc/system/default/nf

SPLUNK INPUTS.CONF ONLY HAS HOST NAME FULL

The Splunk documentation has a page with full details, with example, on what needs to be done to achieve that. If that's true, it's done by props/transforms on Indexer/Heavy forwarder and not in nf on forwarder. The default way requires that Splunk be handled as a special case on the rename either running a command to. Based on your example event, I'm assuming that you're looking to extract the host name from the event data. There are situations were processes are known and hosts will get renamed. Step 1: Splunk HTTP Event Collector (HEC) Configuration. nf Monitor everything from rsyslog directory I know this is an old post, but I want to disagree about 'the better solution is to not set the host in nf'.

Somehow, my Splunk forwarder is not doing that, and it's using the default host, which is Splunk forwarder's hostname. I was assuming nf would still extract IP and use it to override host field, but it didn't work as expected. I have a special case where my remote server is creating a log directory with IP instead of hostname as /var/log/rsyslog//syslog. It's working fine for most of the remote servers. In nf, I am using host_segment = 4 to override host field to remote server's hostname. Remote servers are collecting logs at /var/log/rsyslog//syslog the server hostname, and the server hostname is changed, then event Host field and Host Name in Forwarder Management will differ. If host in nf is set to a static value e.g. If you don't see any results, visit the Troubleshooting page for possible resolution.I have remote servers dropping logs to a syslog server where I have a Splunk forwarder configured to push it to Splunk. Host field in an event is coming from the host stanza in nf. Run a search and confirm that you see results from the forwarder that you set up the data inputs on:.On the receiving indexer, log in and load the Search and Reporting app.Once you have added your inputs, save the file and close it.You might need to create this file if it does not exist. Using your operating system file management tools or a shell or command prompt, navigate to $SPLUNK_HOME/etc/system/local.Whenever you make a change to a configuration file, you must restart the forwarder for the change to take effect. When you upgrade, the installation overwrites that file, which removes any changes you made. For example, if you have the Splunk Add-on for Unix and Linux installed, you would make edits in $SPLUNK_HOME/etc/apps/Splunk_TA_nix/local/nf.ĭo not make changes to the nf in $SPLUNK_HOME/etc/system/default. If you have an app installed and want to make changes to its input configuration, edit $SPLUNK_HOME/etc/apps//local/nf. In nearly all cases, edit nf in the $SPLUNK_HOME/etc/system/local directory. You can configure data inputs on a forwarder by editing the nf configuration file. Configure data collection on forwarders with nf
