How do I confirm the host name & IP address of a host I am logged in in Splunk GUI?
You can get the Splunk server name with this query.
| rest /services/server/sysinfo splunk_server=local | table splunk_server
I don't a reliable way to get the IP address, however. You can try adding a DNS lookup to the above, but that often doesn't work well in corporate networks.
| rest /services/server/sysinfo splunk_server=local
| table splunk_server
| lookup dnslookup clienthost as splunk_server OUTPUT clienthost as ipAddress
