After changing the hostname of a system, you may not be able to access the Uptime Infrastructure Monitor UI due to the hard-coded hostname configuration in the uptime.conf file.

To resolve this issue, ensure that the following parameters in the uptime.conf file are set to the resolvable hostname for the system:

Code Block
languagesql
dbHostname=<hostname> 
httpContext=http://<hostname>:9999 
uptime.conf:monitorHost=<hostname>

If using Uptime Infrastructure Monitor 7.2 or later you may also notice that the Dashboard are now blank.
