Some cloned Red Hat Enterprise Linux 7 systems show blank "Instance Name" values on my deployment server's Forwarder Management tab, and when executing ./splunk list deploy-clients, the forwarders instanceName value is shown as "none".
Where is the instanceName value set?
check /splunkforwarder/etc/system/local/inputs.conf and /splunkforwarder/etc.system/local/server.conf
hope it helps
Sorry, I should have mentioned that I already verified the "serverName = " value in $SPLUNK_HOME/etc/system/local/server.conf, and "host = " in $SPLUNK_HOME/etc/system/local/inputs.conf. They are both set to the same value returned by the "hostname" command on the system.
I also verified that "$SPLUNK_HOME/bin/splunk cmd btool [server|inputs] list --debug" shows the correct serverName and host values; but neither one of those shows an "instance(Name) = " value.
