How to change the Splunk alert url to DNS instead of hostname to link to results?

[dhavamanis]

Can you please tell us how to change the Splunk alert url to DNS instead of hostname to link to results?

currently its showing like:

https://aobxrfabc.amz.arfyd.com:8000/app/IDX/@go?sid=scheduler__admin__IDX__RMD57f21c7e9d1910c90_at_...

We want to change the base url to DNS like this,

https://splunk.abc.com/app/IDX/@go?sid=scheduler__admin__IDX__RMD57f21c7e9d1910c90_at_1420664100_374...

Please provide the configuration details where i can update the settings.

For people searching for the setting, it's hostname = <your hostname> in alert_actions.conf - https://docs.splunk.com/Documentation/Splunk/latest/Admin/Alertactionsconf#GLOBAL_SETTINGS

it has to be set in the alerts.conf file. See Splunk documentation for alerts.conf file
