![]() If there are separate indexers and search head, install the application on all of them. Depending on the OS of the server that's running Splunk, follow the installation recommendations from the Splunk website. Note: Download Splunk for Palo Alto Networks directly from the Splunk site at. This document describes how to configure Splunk for Palo Alto Networks, and covers most problems in configuring Splunk for the first time. Splunk for Palo Alto Networks is a security reporting and analysis tool, and is the result of a collaboration between Palo Alto Networks and Splunk. All documentation is now available at Overview Try using $decideOnStartup and see if that reduces some of your pain points.This article is deprecated. Your environment seems more challenging, so I expert you would have to come up with different solutions. Renaming servers is not allowed in our environment, so we do not have problems with renames. Splunk is installed and configured on the server after first boot, not during the image creation process. Most of our deployments of Splunk are done using Ansible to make sure the proper config is pushed to whatever server needs it. As you point out, you will need a different method of configuring a server that was imaged with Splunk on it. The original question was specifically in regards to packaging the install and deploying to servers, not about imaging a server with the Splunk install on it. A simple restart does not create the nf file. If you set your local/nf file to $decideOnStartup, it should not be overwritten by installs or upgrades. nf is created if it is missing, and it is configured to the actual local host value on first start after an install or upgrade. This way out of the box Splunk will set host to the name of the server, a host name change will be captured by Splunk.Īs you said, this is a really old issue. If you examine the default/nf file on Linux (Splunk 8.0.3) you see: Only set per input overrides in the local/nf file if you need them to be different then the default, for example on Heavy Forwarders.Set a default across the server in local/nf (only is you want to override the Splunk default of $HOSTNAME).This is the short version of my answer again:ĭo not set the host name on nf unless you are overriding a system default. I agree my sentence is confusingly written. ![]() I am not sure your point or if you made a mistake when reading the question or answer. Then you explain how setting the host in nf is a bad idea. I want to disagree about "the better solution is to not set the host in nf". I am sorry I was not more clear in my answer. Not sure what your deal is, insults have no place in support forums. That's the difference of a theoretical knowledge of Splunk administration and having years of actually doing it day in and day out. Yes, I have real world examples of where I wish I had this option today I can't share specifics, but multiple teams manage different types of systems and some times they won't adjust their processes and at some level it makes sense, they can't change their processes around every tool. I would argue that instead of writing out a $SPLUNK_HOME/etc/system/local/nf and making it impossible for Splunk administrators to set a system default, it would have been much better if Splunk had just set the hostname to COMPUTERNAME (or similar variable) in $SPLUNK_HOME/etc/system/default/nf so Splunk admins could push overrides. This makes it much easier to scale Splunk. Eventually it will fix itself without having to have people go out of their way to handle Splunk as a special case AND if they remember they should go out of their way, its as simple as rebooting. The default way requires that Splunk be handled as a special case on the rename either running a command to tell Splunk to cleanup (designed for gold images), a command to remove $SPLUNK_HOME/etc/system/local/nf, or a command to update $SPLUNK_HOME/etc/system/local/nf If you can set it to the environmental variable at install time, then when the rename occurs, you just need a service restart which in the worst case would be the next reboot. There are situations were processes are known and hosts will get renamed. ![]() I know this is an old post, but I want to disagree about "the better solution is to not set the host in nf". ![]()
